Abstract

The technique of adjacent well anti-collision is one of key technologies in the cluster well directional drilling project. Based on research of the magnetic field distribution around casing string, a method is proposed to determine the distance between adjacent wells by measuring the magnetic field generated by the casings while drilling at two different measurement depths of existing well. A prototype of the static magnetic detection anti-collision system while drilling is developed, which comprises the underground probe, the driver sub, the interface box and the software for calculating the relative position between adjacent wells. The prototype can be used with the traditional MWD (Measurement While Drilling) tool on the site. The ground modeling experiment indicates that the distance between adjacent wells calculated by the prototype can properly accord with the results of theoretical analysis and meet the actual requirements of the cluster well drilling engineering. Such the system is expected to provide a highly efficient means for anti-collision in cluster wells.
