摘要
为了研究含油气盆地下生上储式断裂附近的油气分布规律,在油源断裂输导油气有利部位及其影响因素研究的基础上,将油源断裂填充物相对较少的部位和油源断裂断层面凸面脊分布二者叠合,建立了一套油源断裂输导油气有利部位的综合预测方法。应用结果表明:海拉尔盆地贝尔凹陷苏德尔特地区南一段3条油源断裂共发育5个输导油气有利部位,其中,F1油源断裂发育4个输导油气的有利部位,F2油源断裂仅发育1个有利部位,F3油源断裂不发育输导油气有利部位。这些油源断裂输导油气的有利部位处或附近有利于南一段油气聚集成藏,与目前苏德尔特地区南一段已发现油气分布相吻合。
In order to study the hydrocarbon distribution law near the lower-generation and upper-storage faults in oil-bearing basins,the favorable parts for hydrocarbon transmission in oil source faults and their influencing factors were studied,a comprehensive prediction method of favorable parts for oil and gas transmission in oil source faults was established by superposing the parts of oil-source faults where the volume fraction of shale in oil source fault filling is relatively low with the convex ridge distribution of oil-source faults.The application results show that there are five favorable hydrocarbon transmission parts in the three oil source faults in K1n1 of Sudelter area,Beier Sag,Hailar Basin.Four favorable parts for hydrocarbon transmission are developed in oil source fault F1,only one favorable part for oil and gas transmission is developed in oil source fault F2,and there is no favorable part for hydrocarbon transmission in oil source fault F3.Hydrocarbon easily accumulated in the favorable parts for hydrocarbon transmission or near them in K1n1,which coincides with the hydrocarbon distribution found in K1n1 of Sudeelter area at present.This shows that the method in this paper is suitable for comprehensive prediction of the favorable parts for hydrocarbon transmission in oil source faults.
