Total Petroleum System and Inner-Source Natural Gas Exploration in Permian Strata of Junggar Basin

doi:10.7657/XJPG20220603

Abstract

Abstract:

In order to further expand the petroleum exploration and enrich the basic theory and understanding on petroleum geology in Junggar basin，based on the exploration practices in recent years，the characteristics of present petroleum exploration and its trend are summarized，and the total petroleum system in Permian strata and the conditions for large-scale accumulation of unconventional natural gas in inner-source deep strata are described. The results show that the middle and lower reservoir assemblages have become the major exploration targets，deep strata have the conditions for oil and gas accumulation，the source rock controls the distribution of oil and gas，and a distribution pattern with orderly coexistence of conventional and unconventional reservoirs is established. The continuous hydrocarbon supply from high-quality Permian source rocks is the premise for the formation of the total petroleum system，and two sets of oil and gas accumulation systems are found inside source and outside source. Various inner-source reservoirs are developed in the Permian strata，which have great potential for natural gas exploration，especially unconventional natural gas. The understanding not only broadens the petroleum exploration area in Junggar basin，but provides theoretical and practical support for construction of a large oil and gas field. Moreover，it is of great significance for further improving the theory of total petroleum system. Deep inner-source unconventional oil and gas are becoming an important frontier for future exploration in hydrocarbon-rich sags.

Key words: Junggar basin, Permian, Fengcheng formation, total petroleum system, unconventional natural gas, accumulation condition
