<p>A new method has been developed for modeling acoustic monitoring of a layered-block elastic medium with several inclusions of various physical, mechanical and phase hierarchical structures. An iterative process is developed for solving the direct problem for the case of three hierarchical inclusions of l, m, s-th ranks based on the use of 2D integral-differential equations. The degree of hierarchy of inclusions is determined by the values ​​of their ranks, which can be different. Hierarchical inclusions are located in one layer: the first is anomalously dense, the second is anomalously plastic, and the third is anomalously elastic and fluid-saturated density. The degree of filling with inclusions of each rank for all three hierarchical inclusions is different. The simulation results can be used in monitoring studies of the control of fluid return from oil fields developed as part of horizontal drilling.</p><p> </p>

Degree Of Filling

<p>In the enormous and still poorly mastered gap between the macro level, where the well-developed continuum theories of continuous media and engineering methods of calculation and design operate, and the atomic, subordinate to the laws of quantum mechanics, there is an extensive meso-hierarchical level of the structure of matter. At this level unprecedented previously products and technologies can be artificially created. Nano technology is a qualitatively new strategy in technology: it creates objects in exactly the opposite way - large objects are created from small ones [1]. We have developed a new method for modeling acoustic monitoring of a layered-block elastic medium with several inclusions of various physical and mechanical hierarchical structures [2]. An iterative process is developed for solving the direct problem for the case of three hierarchical inclusions of l, m, s-th ranks based on the use of 2D integro-differential equations. The degree of hierarchy of inclusions is determined by the values ​​of their ranks, which can be different while the first rank is associated with the atomic structure, the following ranks are associated with increasing geometric dimensions, which contain inclusions of lower ranks and sizes. Hierarchical inclusions are located in different layers one above the other: the upper one is abnormally stressed, the second is abnormally elastic and the third is abnormally dense. The degree of filling with inclusions of each rank for all three hierarchical inclusions is different. Modeling is carried out from smaller sizes to large inclusions; as a result, it becomes possible to determine the necessary parameters of the formed material from acoustic monitoring data.<br>References<br>[1] Nanotechnology in the coming decade.

A method of maintaining reservoir pressure using a system for formation pressure maintenance of oil reservoirs in the oil fields of Western Siberia is extremely wide-spread. In oil fields as a system for formation pressure maintenance are widely used almost all types of water resources including surface water, groundwater and industrial wastewater. Different calculation methods for predicting the formation and precipitation of salts based on quantitative criteria are used to forecast possible precipitation of calcium carbonate in the flooded oil reservoir areas.

Filling Pathway

Based on the thermodynamic stability and hydrogen bond mechanisms, alkyl dibenzothiophene molecular ratios, 4-/1-MDBT, and 4,6-/1,4-DMDBT, are used to characterize organic maturity and oil migration, which can act as molecular tracers for the filling orientation and pathway in oil reservoir. The results show that the well Shuang32 is the filling point which is close to the source kitchen. Three advantaged oil migration and filling pathways have been discovered, the first one is that oil is charged from well Shuang32 to well Shuang26- well Shuang301- well Shuang31 in northeast orientation, the second one is that oil is charged from well Shuang32 to well Shuang34- well Shuang36 in southwest orientation, the third one is that oil is charged from well Shuang 32 to well Chang502- well Shuang 23 in west-northwest orientation.

The Impact

The seepage underground is rather complicated in the low permeability reservoir and the heavy oil reservoir. One important point to note is that the seepage in these reservoirs does not follow Darcy's law, which brings difficulty to the development of oil field. Study on low velocity non-Darcy percolation theory, the impact on oil production index is analyzed. The key is the summary of the application in order to provide theoretical references for the rational exploitation of the relevant oil fields.

Hydrochloric acid is a chemical compound with broad applications in industry, chemistry, mainly used for the manufacture of agrochemicals, veterinary products, production of PVC, the process of demineralization of water, activation of oil fields, process of tanning skins, process of stamping in the textile industry, production of pharmaceuticals as well as applications in the food industry as an additive in the manufacture of gelatin and sugar. In recent years in Mexico, the chemical industry has held between the third and fourth place in the value of GDP is a 10.7% of this (INEGI, 2015). The growth of this industry every year, explains the increase in the demand for the product of the study dedicated to the purchase, storage, packaging and distribution of hydrochloric acid and muriatic. This company raises the need to distribute their areas of production, optimizing the working conditions and the need to expand to implementing a better distribution of plant that guarantees the security of the worker and increase its production capacity and competitiveness.
