复杂断块砂砾岩油藏地震解释

地震构造层位的解释精度对砂砾岩油藏的预测起关键性作用.本文以夏子街油田夏18-36区块砂砾岩扇体油藏的构造和层位解释为例,研究砂砾岩油藏地震精细解释技术.研究中采用快速地震扫描、相干体分析、精细层位标定、构造样式及断裂组合分析相结合的工作思路,在地震资料品质中偏差先天不足条件下,实现了全工区200余口井的井震统一.运用多种解释方法综合印证来提高砂砾岩油藏的解释精度,为油藏参数的反演和储层预测及注水生产奠定了坚实的基础.

Seismic interpretation of the glutenite reservoir in complicated block area

The structure and horizon interpretation of the seismic data are most important for the glutenite reservoir's prediction.In this text,the seismic data interpretation technique has been studied from am example of the structure and horizon interpretation in Xia18-36 area in XiaZiJie oil field,where the lithology is glutenite bodies.In the study,the methods,the quick seismic scanning,coherence body analysis,the fine horizon tie,structure type and fracture combination are the work guide.We complete the tie of more than 200 wells successfully in the condition of bad seismic data,and use various interpretation method to improve the interpretation accurate of the glutenite reservoir.The fine interpretation forms the basement for the reservoir parameters' inversion,reservoir prediction,injection and production.
