摘要
利用井间地震资料与测井资料进行储层精细解释,可以提供更为准确的储层形态和储层物性资料,进而提高油藏描述的整体精度。其思路为:1收集和综合分析钻井、地质、测井、构造、油藏动态等资料,通过三维地震数据体(地质体)特征和地震相研究,建立井间地震资料数据库;2地质人员根据两口井的井柱资料进行地质分层,按照对比原则和常规作图方法,绘制地质剖面;3开发地震研究人员在地质研究基础上,利用两口井的井柱资料,在井间地震剖面上进行详细解释,以获取相应的解释图件。本文根据上述思路,通过实例对井间小断层、河道砂体内幕结构进行了精细解释,很好地解决了生产中的疑难问题,为地面高精度三维地震资料的精细解释提供了有力依据
Using cross-hole seismic data and logging data for fine reservoir interpretation can provide more accurate reservoir configuration and physical data of reservoir and then improve the precision of the whole in reservoir description.The main ideals are:①collecting and integrative analyzing such data as drilling,geologic,logging,structural and reservoir dynamite and through study of the characteristics of 3D seismic data volume (geologic body) and seismic facies to create database of cross-hole seismic data;②geologists carry out geological layers partition according to well profile data of two wells and draw the geological profile according to correlation principle and common profiling method;③on the basis of geological research and using well column data of two wells,the development seismic researchers carry out detailed interpretation on the cross-hole seismic sections in order to gain relevant interpreted maps.According to above-mentioned ideals and through the cases,the paper carries out fine interpretation for minor cross-hole faults and internal structures of channel sand body,which better solves the difficult problems in production and provides powerful basis for fine interpretation of 3D high-precision seismic data.
