摘要

在综合应用地质、地震、试油和化验分析资料基础上,根据油气成藏动力学理论对油气成藏条件和油气成藏机理进行综合分析,认为,老新地区具备形成岩性油藏和构造-岩性油藏的良好条件。油气是在高地层温度、地层压力场和势能场等主要动力作用下形成和在沉积型、构造型和复合型油气输导体系中运移。油气于荆河镇组沉积中后期聚集成藏,其空间分布具有互补性。直路口断层下降盘是隐蔽油藏勘探的最有利区。
This paper comprehensively applies geologic,seismic,production test and chemical analysis data,and,according to the theories of dynamics of hydrocarbon accumulation,analyzes hydrocarbon accumulation conditions and hydrocarbon accumulation mechanism.It holds that Laoxin Region possesses good conditions for forming lithologic reservoirs or structural-lithologic reservoirs.Hydrocarbon forms under the action of major dynamics about high temperature,high pressure and high potential fields,and migrates in sedimentary type,structural type and composite type hydrocarbon conducting systems.Hydrocarbon accumulates into reservoirs in the middle or late Jinghezhen Formation sedimentation,spatial distribution complementary.The footwall of Zhilukou Fault is considered to be the most favorable exploration area for the subtle reservoirs.
