为精准确定地下井眼的位置和方向,定向井工程师要依靠重力计、磁力计和陀螺仪的测量数据。在过去,要通过中断钻井作业来获得高精度的定向测量数据。如今,地磁测量方面技术的发展使得在钻井过程中获得的实时数据来精准定位水平井,缩小井口距离,在有限的地表位置进行多井钻探成为可能。由于种种原因,各钻井公司在实施钻井作业时需要知道井眼在井下的位置。如今许多斜井和水平井都不再只是简单地穿透储油层,而是在储油层中延着油层钻井,尽可能扩大与油层的接触面。为优
To accurately determine the location and direction of the borehole, directional well engineers rely on measurements from gravimeters, magnetometers, and gyroscopes. In the past, highly accurate directional measurements were obtained by interrupting drilling operations. Nowadays, the development of geomagnetic survey technology makes it possible to locate the horizontal well, reduce the wellhead distance, and conduct multi-well drilling at a limited surface location with real-time data obtained during drilling. For various reasons, all drilling companies need to know the location of the wellbore in the well when performing drilling operations. Instead of simply penetrating the reservoir, many of the inclined and horizontal wells nowadays extend beyond the reservoir in the reservoir to maximize contact with the reservoir. Excellent
