断层控油理论在温吉桑滚动勘探中的应用

THE APPLICATION OF FAULT CONTROL OIL THEORY IN THE PROGRESSIVE EXPLORATION AND DEVELOPMENT OF WENJISANG RESERVOIR

温吉桑多年的勘探开发实践再结合国内外断层研究的新成果,表明断层是控制温吉桑油气成藏的主要因素。从而指出在该区进行滚动勘探的思路是在分析断层特征和控制因素的基础上,通过地震资料的精细处理,精细刻画油田周边断层的空间展布形态,进而寻找小断块含油构造。通过一系列断层处理解释新技术的应用,修改了马红断层、新落实了温南2南断层等,并新发现了温西3-52块、温南2块等新的含油断块。滚动勘探取得了很好的效果。

Several years'exploration and development experience in Wenjisang area integrated with the new accomplish- ments about faults at home and abroad shows that faults are the main factor dominating the reservoir generation here.On the basis of the analysis of fault characteristics and dominating factors,it is pointed out that the thought to carry out progressive exploration and development is to look for small blocks of oil bearing structure through fine process of the seismic date and description of the spatial distribution forms of faults around this reservoir.By the use of a series of new fault process interpretation technique,the fault Mahong was modified and the fault Werman 2 was ascertained,and new oil-bearing blocks__Wenxi 5_52,Wennan 2 etc were discovered.Good results have been obtained in the progressive exploration and development.
