基于磁场测量进行煤层气的井眼连通过程中,建立合适的矢量距离算法一直是研究的难点,其中确定水平井与洞穴井之间的距离和偏离角是进行井眼连通的必要条件.针对矢量距离算法的关键,采用曲线拟合对计算偏离角的关系式进行了推导,论证了偏离角算法的可行性.对算法进行误差分析,用归纳的方法推导出计算磁短节中点与直井之间距离的关系式.研究结果表明偏离角算法与距离计算关系式能够确定磁短节与洞穴井之间的空间位置,对煤层气井眼连通的算法进行了改进.

In the well-trajectory guidance based on the magnetic field survey, establishing the appropriate algorithm has been the research difficulty, of which the distance and deviation angle between Horizontal wells and caves is a necessary condition for connectiv-ity. for the key of vector-Distance algorithm, Curve fitting is used for the derivation of deviation angle algorithm, demonstrating the feasibility of deviation angle Algorithm and the error analysis. Additionally, Inductive method is used for derivation of distance formula between center of mangnet sub and vertical well. Proposed the new algorithm for the bore hole path's direction detection.
