Abstract

Coal measures are well developed in petroliferous basins in China, and coal resources in deep oilfields are abundant. It is preliminarily estimated that gasifiable coal is three times the amount of conventional natural gas resources. Natural gas mining enterprises have certain advantages in resources, horizontal well drilling and completion, production measurement and control technology based on coiled tubing, comprehensive advantages of building underground gas storage in deep oilfields, market support advantages and natural gas substitution benefits to drive them to play their own advantages in technology, pipeline and market integration, according to different needs and corresponding technological maturity. To develop underground coal gasification business in deep oil fields by optimizing the path can effectively and cleanly develop and utilize a large number of coal resources, alleviate the shortage of natural gas supply and improve the self-sufficiency of domestic natural gas.
