【摘要】 近几年来，测井地震结合储层横向预测技术在石油、天然气勘探、开发领域受到广泛关注。如何将纵向分辨率高的测井信息与横向连续性好的地震信息有机地结合起来进行储层预测，是众多地质、物探、测井工作者探讨的焦点。四川测井公司经过数年的努力，结合川东地区的地质特点，探索了一套测井地震结合储层横向预测技术。这套技术从单井岩心资料出发，通过岩性标定测井、测井储层参数计算、储层裂缝分析及多井储层对比，精确评价储层。在此基础上，通过合成记录处理、高分辨率处理、地震速度宽带约束反演、地震特征参数分析、神经网络分析、综合判别分析及储层参数反演等一系列测井地震结合处理分析技术，最终得到各种储层参数的平面预测结果，为滚动勘探部署和储量计算与升级提供依据。到目前为止，这套技术已先后在川东地区明月峡构造带、温泉井构造、五百梯构造、渡口河构造等区域应用，取得了较好的应用效果。更多还原

【Abstract】 In recent years,the logging seism combination reservoir lateral prediction technique has been followed with great interest in oil and gas exploration and development and how to combine the log information with a high resolution in vertical with the seismic one with a good continuity in horizontal to predict the reservoir change is the focus discussed by most of the geological,geophysical prospecting and log engineers.Through hard working for several years,a set of logging seism combination reservoir lateral prediction techniques are developed by the Sichuan Logging Company in light of the geological properties in East Sichuan.According to the core data in single well,the reservoir can be accurately evaluated through the calibration of logging by lithology,the calculation of logging reservoir parameters,the reservoir fracture analysis and multiwell reservoir correlation,etc.Based on this,the lateral prediction results of various reservoir parameters may be obtained finally by use of a series of logging seism combination processing and analyzing techniques as synthetic seismogram processing,high resolution processing,seismic velocity wideband constraint inversion,seismic characteristic parameter analysis,nerve network analysis,comprehensive discriminant analysis and reservoir parameter inversion,etc.,which provides bases for disposing rolling exploration and for the reserve estimation and escalation.Up to now,this set of techniques have been applied in the Mingyuexia structural belt and the Wenquanjing,Wubaiti and Dukouhe structures in East Sichuan early and late and a good effectiveness has been achieved.更多还原
