摘　　要：对大庆探区不同储层不同区块的油气井、进行了有目的的试油试采,用试油试采录取到的压力恢复曲线进行试井分析,得到了有用的地层参数。同时对双对数及导数曲线研究认识发现了不同油气藏边界类型:一条边界、封闭边界、双重介质储层、定压边界,揭示出地下储层地质特征,为合理取得原始有用地质资料,对油井高饱和压力关井初始点确定,裂缝储层压裂前射孔相位确定提出相应措施,指导了试油试采现场施工,为油气田开采提供了可靠数据。For oil and gas wells in the different reservoirs of different blocks in Daqing exploration block,being conducted of the objective oil testing and production,using pressure buildup curve acquired by oil test and production mining to do well test analysis,the formation parameters are obtained.Meanwhile,through studying and understanding on the double logarithmic derivative curve,the types of different oil and gas reservoirs boundary are found.This's one boundary,the closed border,dual media reservoirs,constant pressure boundary,which reveals the underground reservoir geological features,and for reasonably obtaining the original useful geological data,the corresponding measures to determine the initial point of the high saturation shut-in pressure,and the perforation phasebefore the fracturing to fractured reservoir are proposed to guide the field operation of oil testing and production,provide a reliable data for oil and gas exploration.
