曲壳模型在区块地应力研究中的应用

The Application of Shell Model on Block Tectonic Stress Research

介绍了利用曲壳模型计算地应力的方法 ,给出了计算实例和计算结果。通过研究证明利用曲壳模型能够反映地质构造的真实情况 ,又不像三维模型那样工作量大 ,能够满足油田分析地层地应力的要求。通过进行大量的区块地应力研究 ,开发了TP1 30TT高抗挤毁套管 ,在盐岩、泥岩等特殊井段使用效果良好。

The way of calculation tectonic stress has been introduced by using shell model,calculating example and results can be given.The results show that the model can reflect genuine geologic tectonic situation,and it has not more work to do than three-dimensional model.It can meet the need of oil field analyze tectonic stress ,many of blocks tectonic stress have been researched and developed TP130TT high strength case,using at the specific well zones (salt body ,sand body etc)have good application effect.
