油燕沟地区火山岩储层裂缝的研究

Study on fractures in volcanic reservoirs of Youyangou area

根据油燕沟地区火山岩储层的实际情况,利用地震、钻井、测井资料综合分析的方法来预测火山岩的裂隙发育情况,由于研究区内的钻井资料较少,所以主要利用地震资料来研究火山岩的裂缝发育情况。研究结果表明,油燕沟地区中生界火山岩构造裂隙的发育区主要集中在断裂带附近油38-58井及以南地区,位于以北东向延伸为主的断层附近。

Fracture development in volcanics of Youyangou area has been predicted through integrated analysis of seismic, drilling and logging data. Because there is a little drilling data for the study area, fracture development in volcanics is studied mainly through seismic data. The result shows that, fracture developed zones in Mesozoic volcanic structure of Youyangou area concentrate around well You38-58 near the fault zone and to the south, near the almost NE extended fault.
