摘　　要：以绥靖油田延9、长2、长4+5、长6油藏河道砂体为研究对象,根据河道砂体不同的韵律结构、层理类型、夹层分布型式,将河道砂体的含油状况分为4种类型8个亚类:底水型(中高渗油帽底水型,低渗含油底水型),韵律型(正的线型,低渗反韵线型),间断型(低渗条带型,多断复合型),块状型(低渗厚块型,特低渗型)。针对每一种含油结构,优化出其投产措施及投产技术指标,取得了超方案设计的良好开发效果。Channel sandbodies of Yan 9, Chang 2, Chang 4 + 5 and Chang 6 reservoirs are used as objects oi study. According to the different rhythmic structures of channel sandbodies .bedding types and distributional mode of interlayers. oil-bearing status of the channel sandbodies are divided into 4 types of 8 subtypes, which includes: bottom-water type (bottom water of mid-high permeable oil cap, low permeable oil-bearing bottom water), rhythm type (normal rhythmic linear, low permeable inverted rhythmic linear), discontinuous type (low permeable strap type, multi-fault composite type), massiveness type (low permeable massiveness type, extra permeable type). In consideration of each oil-bearing structure, its measures and indications for putting into production are optimized , with better exploration efficiency than that set in project design.
