1·In addition, the stability of wildcat well is generally determined by experience, so the disaster at complex formations is unable to avoid.

此外，野猫井的井壁稳定性一般凭经验判断，所以复杂地层的井壁失稳事故在所难免。

2·The third is determining the type of gas reservoir and the boundary of gas field by combining shallow shear seism with contact wildcat well;

第三是浅层横波地震与触探井相结合，探明浅气藏类型和气田边界；

3·Nowadays, at home and abroad, there are few reports about how to predict rock drillability of wildcat well before drilling in new exploration area.

目前，国内外关于新探区野猫井的岩石可钻性钻前预测方面的研究很少。

4·For wild well, there are lack of logging data and core data. Therefore, present evaluation methods of rock drillability can not be applied to predict rock drillability of wildcat well before drilling.

现有评价方法不能满足对缺少测井资料和岩心资料的野猫井的岩石可钻性进行钻前预测的需要。
