The regional distributions and the development density of fracture are studied by the data such as tectonic curvature, fault data associated with image logging and core description.

利用构造曲率、断层数据结合成像测井、岩心描述等数据，可以对裂缝的区域分布、发育密度等进行研究。

Introduced are principle and method of applying Stoneley wave and the anisotropy of shear wave picked from the dipole shear wave image logging to evaluate the fracture effectivity of igneous rock.

介绍了利用从偶极声波成像测井资料中提取的斯通·利波和横波各向异性，对火成岩裂缝的有效性进行评价的原理和方法。

The result shows that this method is easy, practical and can make an accurate prediction, thus providing a new approach for the prediction of formation fracture pressure from well logging curves.

结果表明，该法简便好用，预测精度高，为应用测井资料预测地破裂层压力开拓了一条新的途径。
