摘要
华北探区断陷石油地质条件、油气富集规律、勘探潜力研究与勘探实践表明,断陷洼槽区剩余油气资源丰富,是深化勘探的重要方向,断陷洼槽区砂体的形成主要受构造带类型、边界断层组合样式、坡折带类型、体系域类型和沉积相类型等控制,油气藏的形成主要受流体动力、油气运移通道、储层临界注入物性、砂体封闭等因素的控制,油气形成与富集主要受油气源、砂岩体、汇流通道等条件的控制,断陷洼槽区还具有形成岩性油气藏的优势和构造油气藏与岩性油气藏的共生互补性特征。
The petroleum geological conditions,the hydrocarbon accumulation and enrichment characteristics,and the exploration potential research and practice show that the residual hydrocarbon resources is abundant in the sags in fault depressions.It is the major target for further exploration.The sands formation in the sags is mainly controlled by the type of structural belts,the boundary fault combination pattern,the type of slope break,the type of system tracts,and the type of sedimentary facies.The development of hydrocarbon reservoirs is mainly controlled by such factors as the fluid dynamic,the hydrocarbon migration pathway,the physical properties of reservoir critical injection,and the sands sealing.The hydrocarbon accumulation and enrichment is mainly controlled by such conditions as the oil and gas source,the sandstone bodies,and the confluence channels.In addition,the sags have the advantages of forming lithologic hydrocarbon reservoirs.Both structural and lithologic reservoirs can develop and complement with each other in the sags.
