随钻测录井参数在水平井地质导向中的应用

Application of parameters of the logging and LWD logging in the geosteering of horizontal well

水平井与常规生产井相比,其优势在于能够有效增加油气层的泄露面积,提高油气采收率和单井产量。但水平井井眼轨迹控制存在诸多难点,如何提高油层钻遇率成为水平井轨迹控制的难题。本文将钻时、岩屑、气测等录井技术与LWD随钻伽马电阻率测井技术相结合,成功应用于水平井地质导向中,取得了较好的应用效果。

Compared with the conventional production well, the advantages of the horizontal well has are the drainage area of the reservoir which can be effectively expanded, and the hydrocarbon recovery and the individual well producing rate can be lifted up. The control of the well course of the horizontal well still exit some difficulties,such as how to drill through more layers. The paper introduces that a successful application of the combination of the logging（drilling hour, cuttings, and gas survey, etc） with the LWD logging（Gamma, and resistivity, etc） in the geosteering of the horizontal well, and a good result is obtained.
