Abstract:
Sha-1 member is the one of the main oil and gas bearing zone in Liuzhuang region.Based on the fine research on features of reservoir and structural,the basic conditions and accumulation characteristics of oil and gas reservoir formation in this area are analyzed.There are four kinds of controlling factors of the oil-gas enrichment:tectonic framework development history and the distribution of oil-gas bearing area are controlled by tectonic framework,the hydrocarbon migration are dominated by gradeⅡ&Ⅲ faults,the enrichment degree of oil and gas accumulation are determined by the location of tectonic,and hydrocarbon enrichment are influenced by the degree of reservoir development.Research findings show that structural and structural-lithology oil-gas reservoirs,forward horst tectonic style migration and segmental tectonic style migration patterns reservoir formation,mainly developed in the sha-1 member.
