Abstract

Abstract

Source rock potential and trap efficiency determine the success of petroleum exploration in the Dunhuang basin, Gansu Province, China. According to the integrated analysis of surface section and sedimentary sequences, the authors analyze the geological elements (source rocks, reservoir, sealing and overlaid rocks) and processes (migration, accumulation and trapping) of the Middle and Lower Jurassic petroleum system in the Dunhuang basin. The results indicate that the Middle and Lower Jurassic dark mudstones and carbonous shales in coal-bearing measures have been inferred to be the main source rocks in the southwestern basin, there is a possibility of using petroleum system theory in the exploration of the Dunhuang basin, Gansu Province in China, and the sandstones lying above the unconformities may be taken as the main targets for hydrocarbon exploration.
