摘要：针对中国东部某油田Y区块测井资料质量不理想和叠后纵波阻抗反演不能进行有效储层预测等向题，开展叠前同时反演工作。资料准备阶段与反演过程中，对测井曲线进行环境校正和标准化处理，对横波曲线估算岩性剖面建立、岩石物理参数分析等技术环节进行严格质量控制。反演得到各类岩石物理参数数据体，结合岩石物理参数分析优选出储层敏感参数，进行有效储层预测。分析表明，叠前同时反演技术可以作为研究区储层预测的有效技术手段，反演预测结果与研究区主力油层吻合良好，符合研究区地质认识，并指出扇三角洲前积砂体中上部是有利的探目标。

Abstract: In the light of the problems of not ideal well-logging data quality, not effective reservoir prediction by eeesae and inversion process, the environmental correction and normalization of the well logging curves are accomplished, and the strict quality controls of technical links such as the shear wave estimation, lithological section establish-ment, petrophysical parameter analyses are taken seriously. Each kind of the petrophysical parameter data body is obtained with the help of the inversion, and moreover integrating with the above parameter analyses, the sensitive parameters of the reservoirs are optimized, and finally the effective reservoir prediction is completed. The analyses show that the pre-stack simultaneous inversion technique can be regarded as an effective technical measure for the reservoir prediction in the study area, there are much better coincidence between the predicted results and main oil reservoirs and the geological understandings in the study area. And furthermore the favorable exploration targets are pointed out: the middle and upper parts of the sandbodies of the fan delta front.
Key words: pre-stack simultaneous inversion; shear wave estimation; petrophysical parameter; wavelet estimation ; reservoir prediction
