在川东地区二级构造单元中，不论是高陡背斜，或是低陡构造，其陡翼轴部附近都存在一个断陡带。由于这些断陡带地质构造复杂，地震信息杂乱，影响准确解释。在勘探上，导致了部分探井的失利，制约着许多构造主体部位勘探领域的扩展；在气田开发上，断陡带的构造细节解释不正确，偏离地下实际，赞成了气藏地质模型与气藏动态特征不吻合，静态储量与动态储量误差大，直接影响了气藏开发设计方案的准确性。为此，在卧龙河断陡带构造细节解释中，运用地质、地震、钻井、试井、气藏工程等多学科知识进行综合分析，找出了断陡带构造细节变化的规律。初步形成一套行之有铲的解释方法。这种方法、效果好、可信度高，对今后在川东断陡带构造细节解释中具有一定的参考作用。

Comprehensive Interpretation of Steep Faulted Zone of Wolonghe Structure by Use of Multiple Disciplines Knowledge

In the secondary structural element in east Sichuan region,there exists a steep faulted zone in the vicinity of all steep limb axex of both high steep anticline and low steep structure.These steep faulted zones affect the accurate interpretation due to their complex geological structure and disorderly seismic informations which leads a partial exploration wells to suffer a setback and restricts the extension of the exploration sphere of the main part of many structures in the exploration and causes the geological model of the gas reservoir to be nonidentical with the performance characteristics of the gas reservoir and the error between the dynamic reserves and static ones to be great,directly affecting the accuracy of the development plan due to incorrect interpretation of the structural detail of the steep faulted zone and due to deviation from underground practice in gas field development.For this reason,a comprehensive analysis by use of multiple disciplines knowledge (including geological and seismic prospecting,drilling,well test and gas reservoir engineering,etc.)was made in the interpretation of the structural detail of Wolonghe steep faulted zone,finding out the changing law of the structural detail of steep faulted zone and forming and initially effectual interpretation method which has a good effect,high fiduciary level and a certain reference value for the interpretation of the structural detail of the steep faulted zones in east Sichuan.
