Abstract In the light of the eternal discussion regarding the sources of hydrocarbons for the initial oil and gas-forming substance, it is possible to recognize the legitimacy of both organic matter, which is confirmed by the biogenic theory of the origin of oil, and deep gases, declared by supporters of the theory of the inorganic concept, referring to the extraordinary richness of hydrocarbons in the mantle. But, the catagenic stage, the process of obtaining oil from the initial substance, in which the primary carbonaceous substance (often under such hypothetical concepts as “micron-oil”, “fluids”) passes into hydrocarbons in the form of oil deposits, causes no less scientific interest and also insufficiently studied. The author sees it as fair to attempt to put emphasis on predominantly geodynamic conditions, tectonic stresses, physico-chemical and thermobaric conditions, the generation of hydrocarbons, on the basis of the synthesis of hydrocarbons in any geological period. The article proposes the author’s chemical model describing the low-temperature polycondensation synthesis of hydrocarbons from water and carbon dioxide in the process of mechanical reactions on the surface of a rock model.

The relevance of the article is associated with the importance of the object of the research. Dozens of unique and giant oil and gas fields, such as Urengoyskoye, Medvezhye, Yamburgskoye, Vyngapurovskoye, Messoyakhskoye, Nakhodkinskoye, Russkoye, have been identified within the Cenomanian complex. The main feature of Cenomanian rocks is their slow rock cementation. This leads to significant difficulties in core sampling and the following studies of it; that is the direct and most informative source of data on the composition and properties of rocks that create a geological section.The identification of the factors, which determine the slow rock cementation of reservoir rocks, allows establishing a certain order in sampling and laboratory core studies. Consequently, reliable data on the reservoir and estimation of hydrocarbon reserves both of discovered and exploited fields and newly discovered fields that are being developed on the territory of the Gydan peninsula and the Bolshekhetskaya depression will be obtained. This study is also important for the exploration and development of hydrocarbon resources of the continental shelf in the waters of the Arctic seas of Russia as one of the most promising areas.As a result of the analysis, it was found that the formation of rocks of the PK1-3 Cenomanian age of the Bolshekhetskaya depression happened under conditions of normal compaction of terrigenous sedimentary rocks that are located in the West Siberian basin. Slow rock cementation of reservoir rocks is associated with relatively low thermobaric conditions of their occurrence, as well as the low content of clay and absence of carbonate cements. Their lithological and petrophysical characteristics are close to the analogous Cenomanian deposits of the northern fields of Western Siberia and can be applied to other unconsolidated rocks studied areas.

The Relationship

The microstructure of reservoir rocks plays an important role in oil and gas accumulation and production. We examine a universal method to evaluate these properties of rocks, such as pore tortuosity, matrix porosity, and connectivity, and we respectively construct a 2D numerical reconstruction rock model with different microstructure parameters by the Monte Carlo method and the quartet structure generation set method. We further study the heterogeneity (characterized by fractal dimension and tortuosity) of the constructed image for reservoir rocks by the numerical and theoretical analysis and obtain the formulas for fractal dimension and tortuosity versus porosity. The simulation results show that the logarithmic relation is between the pore fractal dimension and porosity, and the relationship between tortuosity and porosity has the form of power. This process provided an important method to advance 2D reconstruction technology of reservoir rocks and effectively determine the relationship between microstructure and porosity.

A few pipelines transport different unsafe items, for example, synthetic concoctions, profoundly unstable fluids, and anhydrous alkali, or carbon dioxide. As per information from the 2018 NHIS-OHS, laborers utilized in mining and oil and gas enterprises had high commonness paces of introduction to conceivably unsafe work association attributes and risky synthetic compounds gas spills. In our task we are intending to recognize the careful area of the break. A gas spill locator is a gadget that identifies the nearness of gases in a region, as a major aspect of a word related security framework. This kind of hardware is utilized to identify a gas spill, warmth, fire and different emanations and can interface with a human. A controller can sound an alert to human in the region where the variation from the norm is happening, allowing them the chance to find the break without human hazard. This kind of gadget is significant in light of the fact that there are numerous gases that can be hurtful to human. This undertaking measures and alarms the specialist from this risk. The locator unit will be versatile vehicle based gear. This unit will move alongside the pipe line, screen the air and gives ready messages. The versatile security framework will consistently quantify the warmth, CO and H2S level in the environment or in shut zones where human are working[19],[20],[21]

Background. In terms of oil and gas, the territory of the Chezhen depression has been studied insufficiently compared to the neighbouring same-range depressions. These depressions complicate the first-order Jiyang depression, geographically coinciding with the largest Shengli hydrocarbon field. In recent years, much geological and geophysical information about the oil geologyof the Chezhen depression has been accumulated, which allows its prospecting oil and gas potential to be assessed.Aim. To reveal regular features of the geological structure and location of oil deposits in the Chezhen depression in order to support the prospecting and exploration work within the Chezhen block of the Shengli field.Materials and methods. A comprehensive analysis of literature data and collected materials was conducted. A historical and geodynamic study of the evolution of the studied area according to literature data was carried out, along with an analysis of the most recent geological and geophysical information and exploration data based on the materials of the “Shengli AKOO Sinopek” oil company. The analysis was based on the data from 52 drilling wells and the results of seismic surveys performed in the central part of the Chezhen depression.Results. Specific features of the block geological structure of the area under study were established, which formed under the repeated influence of large-scale horizontal tectonic movements occurring at different periods of geological history. The role of the most recent fault system in the modern spatial distribution of oil deposits was determined.Conclusions. Our studies demonstrate a great prospecting potential of the Chezhen depression territory, where the discovery of new industrial oil deposits can be expected.

New ideas about the origin of oil and gas are discussed. They are caused by the discovery of the phenomenon of replenishment of oil and gas reserves in exploited fields. This phenomenon was discovered by the Russian geologists a quarter of a century ago, and a little later it was theoretically justified on the basis of the biosphere concept of oil and gas formation. As a result, the well-known «organic hypothesis» and «mineral hypothesis», which have long time competed in oil and gas geology are being replaced by new representations today, according to which oil and gas are the inexhaustible useful fossils of our planet. And their deposits are traps of movable carbon that circulates via the Earth’s surface in three main cycles with periods of ~108-109, ~106 -107 and ≈ 40 years. The 40-year carbon biosphere cycle, which was not previously taken into account at all, plays a main role in replenishment of deposits. Its accounting makes it possible to balance the carbon and water cycles in the biosphere, taking into account the economic activities of people and modern formation of oil and gas in the bowels, and also open up the possibility of exploiting deposits as constantly replenished sources of hydrocarbons.

Repeatability And Reproducibility

Carbon dioxide (CO2) corrosion is one of the most dangerous types of destruction of metal products in the oil and gas industry. The field steel pipelines and tubing run the highest risk. Laboratory tests are carried out to assess the resistance of steels to carbon dioxide corrosion. However, unified requirements for certain test parameters are currently absent in the regulatory documentation. We present the results of studying the effect of the parameters of laboratory tests on the assessment of the resistance of steels to CO2 corrosion. It is shown that change in the parameters of CO2 concentration, chemical composition of the water/brine system, the buffer properties and pH, the roughness of the sample surface, etc., even in the framework of the same laboratory technique, can lead in different test results. The main contribution to the repeatability and reproducibility of test results is made by the concentration of CO2, pH of the water/brine system, and surface roughness of the samples. The results obtained can be used in developing recommendations for the choice of test parameters to ensure a satisfactory convergence of the results gained in different laboratories, as well as in elaborating of a unified method for assessing the resistance of steels to carbon dioxide corrosion.

The element carbon Carbon dioxide emissions are increasing primarily as a result of people's use of fossil fuels for electricity. Coal and oil are fossil fuels that contain carbon that plants removed from the atmosphere by photosynthesis over millions of years; and in just a few hundred years we've returned carbon to the atmosphere. The element carbon Carbon dioxide concentrations rise primarily as a result of the burning of fossil fuels and Freon for electricity. Fossil fuels such as coal, oil and gas produce carbon plants that were photosynthesized from the atmosphere over many years, since in just two centuries, carbon was returned to the atmosphere. Climate alter could be a noteworthy time variety in weather designs happening over periods ranging from decades to millions of a long time. The permanent change in climatic conditions, or in the time period of long-term natural conditions, indicates irregularity in climatic conditions. Discuss toxins are pollutants that have an adverse impact on the ecosystem through interferometry's with the climatic environment, plant physiology, creature organisms, complete biological systems and human property in the form of agricultural or human crops. We list the best climate to represent the fact that global climate change has been identified as one of the major environmental problems facing humanity in the 21st century. In this context, the list of "classic" poisons must be included alongside substances such as oxides of nitrogen or sulfide. Certain environment limiting agents – the most crucial of them being carbon dioxide – which otherwise do not damage life formations. On the other hand, climate research has linked some compounds that have long been known to discuss toxin (occasionally dark CO2) with the warming of the climate.
