Types of Hydrocarbon Migration Pathways and Hydrocarbon Accumulation in the Yakela Fault-Convex, Tarim Basin

Article Preview

Abstract:

The existence of abundant hydrocarbon has been discovered in the Yakela Fault-convex, Tarim Basin, after reconstructing and superimposing for several periods. Through interpretation of 3D seismic data up to date, combined with the circumferential field geology, after comprehensively analyzing the characteristics of development on hydrocarbon migration passages and its relationship with hydrocarbon accumulation, this paper holds that it is divided into fault type, unconformity type and carrier bed type in the Yakela fault-convex. The unconformities and the carrier beds are the main lateral migration passage of gas and oil for long distance. The faults are the main vertical migration pathway of hydrocarbon, and the hydrocarbon can arrive at any strata with fault. It is significant to know the hydrocarbon migration pathways in the study area for exploration in future.
