对桥东油田进行了石油地质综合研究,明确了该油田的油气成藏条件、油藏类型、油气分布规律及其主控因素。桥东油田具有有利的油源条件、储盖组合和圈闭条件,油藏类型为构造油藏和复合油藏,纵向上分布于古近系沙河街组沙三上亚段和沙四上亚段,平面上富集于有利的正向构造带;断层控制油气的运移与成藏,构造背景控制油气的平面分布,储盖组合条件制约油气藏的发育;取得的认识对油田下一步勘探具有一定的指导作用。
A comprehensive petroleum geology study has been carried out on Qiaodong Oilfield, and the hydrocarbon accumulation conditions, reservoir types, oil and gas distribution laws and their controlling factors have been clarified. Qiaodong oilfield has favorable oil source conditions, reservoir-cap assemblage and trapping conditions. The reservoir type is structural reservoirs and composite reservoirs, and longitudinally distributed in the upper third and upper reaches of Shahejie Formation of Shahejie Formation of Paleogene , The plane is enriched in the favorable positive tectonic belt; the fault controls the migration and accumulation of oil and gas, the tectonic setting controls the plane distribution of oil and gas, and the combination of reservoir and cover restricts the development of oil and gas reservoirs; A certain guiding role.
