摘要

为研究断裂在太东地区葡萄花油层中的作用,利用地震和钻井资料,在油藏解剖基础上,分析太东地区断裂发育及分布、油藏类型及分布和断裂在油聚集中的作用.结果表明:太东地区发育71条断裂,走向以北北东、近南北和北北西向为主,剖面上呈似花状组合,平面上呈5条密集带分布.油藏类型以断层—岩性和断块油藏为主,剖面上油层由上至下逐渐减少,平面上由东至西含油面积逐渐减少.断裂对油藏的形成与分布的控制作用表现在:北北东和近南北向断裂遮挡为油气聚集提供圈闭;反向断裂较顺向断裂更有利于油气聚集成藏;断裂侧向封闭性控制油气聚集程度.
In order to study controlling effects of faults in P oil layer in Taidong region by means of existing seismic and drilling data,based on anatomy of oil reservoirs,development and distribution of faults,types of oil reservoirs and controlling effects of faults on oil accumulation were studied.It is considered that there are 71 faults with NNE,NS and NNW trend in Taidong region.They form flower-like fault combination in section.They form 5 fault concentrated zones on the plane.There are two types of fault-lithology and fault block oil reservoirs.The number of oil layers gradually become fewer from upper to down in section.Oil-bearing area gradually become smaller from east to west on the plane.Controlling effects of faults on oil accumulation displays in following a few aspects: seal by faults with NNE and NS trends provides traps for oil to accumulate;oil is more favor accumulation near transoid fault than that near cisoid fault;lateral seal of fault controls oil accumulation degree.
