水平井地质导向自然伽马探边技术研究

Study on geologically guided gamma ray edge exploration technology for horizontal Wells

通过随钻自然伽马测井对水平井的井眼轨迹与地层边界之间的距离进行计算,对井眼的钻进起到更好的指导作用。首先对自然伽马探边技术识别地层边界的原理与模型展开深入分析;在此基础上,提出水平井地质导向自然伽马探边技术的研究。

In this paper,natural gamma logging while drilling is used to calculate the distance between horizontal well trajectory and formation boundary,which plays a better guiding role in borehole drilling. Therefore,the principle and model of identifying stratigraphic boundary by natural gamma exploration technique are analyzed in this paper. On this basis,the research of geological guided natural gamma exploration technology for horizontal Wells is put forward.
