X油田目前已进入开发中后期，薄油层的开发动用成为其保持稳产的重要措施之一。为提高挖潜措施的有效性，需对油藏特征进行精细描述，尤其是储层展布的刻画。由于储层薄、埋藏深、物性横向变化快，常规的地震属性分析及叠后波阻抗反演技术均无法对其进行有效识别和预测。该文以L4油藏为例，采用叠前纵横波联合反演技术对储层展布进行了预测，钻后砂体展布与钻前预测相吻合，使得依据本文研究成果所设计的调整井达到了预期效果，说明叠前纵横波联合反演技术在本地区具有较好的应用价值。

X oilfield has entered the later stage of producing,the development of thin reservoir has become one of the important measures to maintain stable production.In order to improve the effectiveness of potential measures,fine description of reservoir characteristics is necessary,especially the reservoir prediction.Because of the thin reservoir,burial depth,and lateral variation,conventional seismic attribute analysis and poststack acoustic impedance inversion are unable to carry on the effective recognition and prediction.In this paper,the L4 reservoir is taken as an example.The distribution of reservoir is predicted by using Pre-stack simultaneous inversion of P-wave and S-wave,and the actual drilling results are quite consistent with the predicted results,which makes the adjustment well designed based on the results of this paper has reached its expected.This shows that the technique of Pre-stack simultaneous inversion of P-wave and S-wave has a good application value in this area.
