Abstract
|
A combination of seismic, logging , production testing , and other relevant information , the the forming rules Xing'anling Group Sudeerte . Biomarkers , aromatics content similarity analysis of gas chromatography geochemical indicators to determine Xing'anling Group crude oil mainly from the the Nantun source rock, and a small amount from Xing'anling Group source rocks . The core observation, thin microscopic identification of relevant information we can see that the reservoir Ⅰ Oil group Xing'anling Group II reservoir group for the transition between the rock of pyroclastic and normal deposition of debris ; Xing'anling Group Pore Types native pores , followed by the porosity of the fracture-cave . By study area Nantun for some of Xing'anling Group shale and the overlying Sec of mudstone caprock for caprock and closed . The caprock existence abnormal pore fluid pressure , capillary closed , closed two closed type . The Reservoir Evaluation results show that the shell 16 blocks west of the oil group IV and III oil group , Tony 14 Block IV oil group , Ⅱ oil group and Ⅰ oil group and shellfish 28 blocks east and northeast IV oil group and ⅲ oil group for better reservoir . Combined with raw reservoir, cap , preservation conditions and other factors , that Xing'anling Group reservoir type main fault blocks and faults lithologic reservoirs , hydrocarbon accumulation and distribution is mainly affected by the source rock , the migration pathways of control and trap types .
