Hydrocarbon Source Rock Quality and Analysis of Hydrocarbon Potential in K_1sh of Zhaozhou Sag

Abstract:

Use of drilling, logging and seismic data, research on K_1sh geology and geochemical characteristics of Zhaozhou Sag, combining the geohistory, thermal history and chemical kinetics evaluation of tight gas resource potential of K_1sh. The results show that, TOC of K_1sh in Zhaozhou Sag mean value is 1.12%; The type of organic matter mostly of type III andII₁; the average maturity of 2.41%, more than 70% entered the mature stage. Mudstone are developed widely, the average thickness of 140 meters. In the simulation experiments based on hydrocarbon generation thermal, In the study area by using chemical kinetic method for the quantitative evaluation of hydrocarbon source rock in the deep formation. The results show that, K_1sh in Zhaozhou Sag total generating capacity is 4.68×10¹²m³, the results can be seen from the generated gas, the K_1sh in Zhaozhou Sag has high resource potential.
