<p>There are enormous resources of unconventional gas in coal measures in Ordos Basin. In order to study the geological characteristics of unconventional gas in coal Measures in Ordos Basin, we analyzed and summarized the results of previous studies. Analysis results are found that, the unconventional gas in coal measures is mainly developed in Upper Paleozoic in Eastern Ordos Basin, which including coalbed methane, shale gas and tight sandstone gas. The oil and gas show active in coal, shale and tight sandstone of Upper Paleozoic in Ordos Basin. Coalbed methane reservoir and shale gas reservoir in coal measures belong to “self-generation and self- preservation”, whereas the coal measures tight sandstone gas reservoir belongs to “allogenic and self-preservation”. The forming factors of the three different kinds of gasses reservoir are closely related and uniform. We have the concluded that it will be more scientific and reasonable that the geological reservoir-forming processes of three different kinds of unconventional gas of coal measures are studied as a whole in Ordos Basin, and at a later stage, the research on joint exploration and co-mining for the three types of gasses ought to be carried out.</p>

The World

Many countries in the world begin to attach great importance to the utilization of the unconventional gas. In some areas, tight gas, Coalbed methane (CBM) and shale gas have came into commercial development. The unconventional gas resources are very abundant in China. They developed rapidly in recent years, and some progress has been made. CBM in Qinshui Basin has been commercially developed successfully. Shale gas resource is also very abundant and has a good development prospect. Besides, the gas hydrate has a great potential in resources.

Gas Potential

During underground coal mining operations, greenhouse gas emissions are produced, mainly methane. These emissions originated not only from coal, but also from the subsidence of the surrounding rocks. Until now, emissions from surrounding rocks have been calculated from international tables, but it is proposed that they be calculated from gas measurements on coal-adjacent rocks in coalbed methane exploration in which drillings and canisters desorption systems were used in the provinces of Boyacá and Cundinamarca. The gas contents of the surrounding rocks, and thus the emissions, are less than those found in the coal at the same depth. The areas with the highest gas content values in the surrounding rocks are Samacá and Chinavita with contents between 40 and 50 feet3/ton. These values equate to one-third or a quarter of those obtained from the coalbeds close to such samples. The highest gas content did not correspond to the highest coal rank (Socotá) which would be explained by the intense folding and faulting in that area. The gas contents found in the shales (clays) of the Guaduas formation can also be used as a proxy indicator for older and deeper formations that could have good shale gas potential.

Unconventional Oil And Gas

With the continuous improvement of the understanding of the geological law and continuous innovation of unconventional oil and gas exploration and mining technology, China has made great breakthroughs in newly-added geological reserves of unconventional oil and gas resources, such as shale gas, coalbed methane, etc. But for many reasons, attention has not been paid to oil and gas resources (petroleum, natural gas, coalbed methane, shale gas), and regional remote sensing monitoring research has not been carried out. Based on high-resolution remote sensing data of the year 2018 and human-computer interactive interpretation technique, this paper built remote sensing interpretation signs of oil and gas mines, carried out exploration of remote sensing monitoring methods for oil and gas mines, completed remote sensing monitoring over development status of oil and gas mines in Ordos Basin, and proved feasibility of remote sensing monitoring method.
