利用电子岩芯实现裂隙产状的三维测量研究

目前，钻孔内裂隙的产状测量主要在二维钻孔电视展开图上进行，存在裂隙面不明显、不直观，判别产状时受人为影响较大等问题。电子岩芯是基于钻孔孔壁与岩芯耦合关系建立的三维模型，利用电子岩芯测量裂隙的产状与在二维钻孔电视展开图上测量产状的原理一致，且相比二维模式下测量更有优势。基于电子岩芯进行了三维裂隙产状的测量研究，通过三维平面与裂隙面的匹配实现了对裂隙产状的测量。结果显示，在电子岩芯三维模型中进行测量更为直观、明显，减少了人为因素的影响。

Research on realization of measuring dip of fracture on 3D model using electronic rock core of borehole

At present, the fracture occurrence measuring in borehole is mainly conducted on 2D outspread drawing of borehole TV and the problems of unobvious fracture face, indirect and artificial influence on fracture occurrence etc. are existed. Electronic core is a kind of 3D model established on the couple relation of bore-hole wall and rock core, and the measuring principle of fracture occurrence using electronic core is consistent with that on 2D outspread drawing of borehole TV and has more advantages than 2D measurement. The measuring research on 3D fracture occurrence based on electronic rock core was conducted and fracture occurrence measuring through matching of 3D plane and fracture face was realized. The result shows that the measuring on 3D model is more direct, obvious and less artificial influence.
