前导模拟技术是水平井钻井地质导向的关键技术之一。该文结合国外水平井钻井的典型实例,介绍了前导模拟技术的应用现状,详述了前导模拟地质模型的建立过程以及随钻过程中根据LWD(随钻录井)记录曲线与模拟曲线的对比来实现水平井地质导向的情况。该项技术的开发应用对提高水平井钻井技术水平具有重要意义。
Leading simulation technology is one of the key technologies of horizontal well drilling geosteering. Based on the typical examples of horizontal well drilling in foreign countries, the application status of the leading simulation technology is introduced. The establishment process of the leading simulation geological model and the comparison between LWD (logging while drilling) recording curve and the simulation curve while drilling are described To achieve the horizontal well geological guidance situation. The development and application of this technology is of great significance to improve the level of horizontal well drilling technology.
