振幅属性在M气田盒1段储层预测中的应用
APPLICATION OF AMPLITUDE ATTRIBUTES IN RESERVOIR PREDICTION FOR THE P1X1 SECTION OF M GAS FIELD
摘要
Abstract
The P1x1 (the He-1 Section of the Xiashihezi Formation of the Permian) channel sand body,the main reservoir of the M gas field,is the most important exploration target in this region.It is a typical lithologic reservoir with low porosity and permeability and thus hard to make seismic prediction.In this paper,we presented a practical way for reservoir prediction.Upon the principle of seismics and using of method of statistics and data analysis,actual drilling data,in addition to the geophysical characteristics of actual logging data are collected and processed by the seismic forward modeling.As the results,the seismic section features of P1x1 are summarized,and then the amplitude attributes of the post-stack seismic data,which can be used as a criterion for distribution prediction,are extracted from these features.According to the actual drilling data of 40 wells in this area,the coincidence rate of amplitude attributes and actual drilling data is as high as 75％,which shows a good effect of prediction.The process to draw amplitude attributes from seismic post-stack data is rather simple.It requires relatively small amount of data and the workload is not heavy.It is easy to carry out and only requires limited hardware support.关键词
