摘要
水平井录井过程中,只有数字化精细描述井眼轨迹,才能将录井信息与井眼轨迹以数据的形式联系起来,有效地指导水平井施工。在水平井录井应用软件研发过程中,应用反推法建立了定曲率井眼轨迹数据离散、井眼轨迹盲区预测公式,实现了井眼轨迹的数字化描述,在此基础上将井眼轨迹与录井曲线变化有机地结合在一起。结合水平井现场录井实际,总结出录井气体参数变化反映水平井油气水特征的规律,将该方法用于指导水平井施工,有效地提高了水平井钻遇率,为水平井录井技术的拓展奠定了一定的基础。
During the horizontal well mud logging,only by the digitalized fine description of the borehole trajectory,will mud logging information be contacted with the borehole trajectory in the form of the data,guiding the horizontal well operation effectively. During the development of the application software for horizontal mud logging,the inverse inference law has been used to set up the formula for data scattering with the fixing curvature borehole trajectory and for predicting the borehole trajectory blind area,to realize the digitalized description of the borehole trajectory. On the basis of this,the borehole trajectory is connected with mud logging curve change organically. Combining with the practical mud logging of the horizontal well,the authors summed up the law of the mud logging gas parametric change to reflect the oil,gas and water characteristics for the horizontal wells. When the method turns to be used to guide the horizontal well operation,it has raised the horizontal well drilling rate effectively and established the certain basis for the mud logging technology of the horizontal wells.
