| Abstract: | This paper deals with the last 3 lateral directional drilling holes of cluster directional wells of the AI platform. In the presence of magnetic disturbance of the main and proximal wells, the three drill holes with the minimum inteval of 0.6m were drilled in by means of gyro lateral directional drilling and pilot drilling technology. The technological characteristics, safety measures and anti-impact technology of the lateral directional drilling are sum arized. An approach to the rate of drilling, rate of deviation change and control of the well pit path in the gyro lateral directional drilling are made. |
