摘要
本文为了解决低勘探程度区由于缺少测井资料而难以进行储层评价的难题,发展了背景驱动地震反演技术.该技术通过利用区块周边测井资料的背景驱动,克服了低勘探程度区块内因缺少测井资料而难以建模的难题.同时,该技术还规避了压实作用的影响,更有利于反演结果的解释.通过模型和实际数据测试,证明该方法具有较强的抗噪性,并且可以得到准确的反演结果,对低勘探程度区储层评价具有一定的参考价值.
In order to solve the problem of reservoir evalution in low exploration block for the absence of the drilling logging data,We develop a method called ＂background driven seismic inversion ＂.The method makes use of well background information to overcome the difficult problem of modeling in low exploration block.Otherweise,it also can avoid the impact affect which makes the inversion explaination easier.Through the model and actual data test,proved that the method has a strong ability of noise resistant and can obtain more accurate results.It can provide a favorable technical surport of reservoir evalution in the low exploration block.
