Characterization and Key Controlling-Factors of Reservoir in the Lower Sha4 of Wuzhong
摘要
Abstract
The geology,seismic,logging,test and other data are used to characterize the hydrocarbon reservoir and identify hydrocarbon enrichment factors in the lower Sha4 of Wuzhong.It is considered that the reservoir in the lower Sha4 is featured by"beads-shaped"in the plane,that is scattered distribution with poor continuity. It is"tooth-brush-shaped"along the fault in the longitudinal direction,that is superimposed multi-reservoir with independent oil-water and temperature-pressure systems for each reservoir. The reservoir in the lower Sha4 is mainly controlled by a variety of factors such as source-rock,migration system,temperature-pressure system,etc. The source-rock controls the reservoir distribution and hydrocarbon enrichment,the migration system affects the hydrocarbon accu-mulation pattern and accumulation horizon,and the temperature-system influences the hydrocarbon accumulation phase and enrichment zone.This research could provide certain guidance for the further hydrocarbon exploration and target selection in the lower Sha4 of Wuzhong.关键词
