综合识别方法在低阻油气层勘探中的应用
|
摘要
近年来,吐哈油田在岩性油气藏的勘探中做了大量的研究并取得了很好的效果,目前油气勘探正处在由构造油气藏向岩性油气藏勘探转变的转折时期,但由于岩性油气藏固有的特性,对其储层预测、油水层识别存在诸多困难,在测井资料上反映为油层电阻率低与水层电性差异小和含油饱和度低等特点。该文以吐哈盆地台北西部的低电阻率油气层为例,从低电阻率油层的成因分析出发,在系统总结低电阻率油藏地质特征、形成机理的基础上,详细研究了低电阻率油气层地质录井、测井资料响应特征,并结合地震资料探索出一套能有效识别低电阻率油层的综合方法,对今后该类油气层的解释评价起到一定的借鉴作用。
In recent year,with the expanding petroleum exploration,lithologic hydrocarbon reservoir has become the key for the further oil & gas exploration.Because of its inherent characteristics,such as low resistivity,little difference from water layer electric property,and low oil saturation etc.,there are many difficulties in the reservoir prediction and the identification of the water/oil bed.Based on the analysis of geologic features of low-resistivity hydrocarbon reservoir and formation mechanism,referred to the origin,the geological logging and well logging data of low-resistivity hydrocarbon reservoir in northern Taibei,Tuha Basin were studied.A set of comprehensive methods that could be used to identify low-resistivity reservoir was put forward,which is significant for the future reservoir interpretation and evaluation.
