三塘湖盆地牛东火山岩处理和测井识别技术研究

SEISMIC PROCESSING AND LOGGING RECOGNITION TECHNOLOGY IN VOLCANIC ROCKS IN SANTANDHY NIUDONG

由于火山岩以裂缝性储集层为主,其识别与评价一直是油气勘探的难点,本文通过地震波及声波速度分析、地震反射特征分析、三瞬信息分析及测井声波约束反演等技术分别对三塘湖盆地火山岩储集层进行了响应特征研究,为有效圈定和评价火山岩储集性提供了可靠的依据。

Due to volcanic rocks' being nonhomogeneous,related recognition and prediction technology is still one of the teasers exsiting in oil and gas exploration.In this thesis,the prospecting flow mainly consists of analysis of velocity,analysis of seismic reflection property,analysis of information of the 3 instantaneous,and constrained inversion of sonic logging which are synthetically applied to help discern 4 sorts of reservoir rocks in Santanghu Basin effectively,which are listed as breccia,andesite,basalt,and diabase.It is the first time that their horizontal distributions have been blocked out respectively,and thanks to this fruit,prediction of cleft reservoir is proceeded smoothly,which contributes to supply the exploration and development of volcanic rock reservoir with definite theoretical foundation and some technological methods.
