Research on the Design Method of Spoon Borehole Track for Cluster Platform Well Set

The “Well Factory” horizontal well operation mode has become a key technology for the economic and efficient development of unconventional oil and gas reservoirs. In order to solve the problem of reservoir utilization in this part, foreign countries have proposed the concept of spoon shaped horizontal wells, while little research has been reported in China on the optimal design of spoon shaped horizontal well platform well sets. In this paper, we propose that the key to the design of spoon borehole track is to optimize the front distance of the target. In order to reduce the risk of collision, we establish a method to optimize the design of the borehole track of the spoon horizontal well group by optimizing the layout of the well site and staggering the location of the slope making point and target area. Practice shows that spoon shaped horizontal well B has 10–15t more casing friction than conventional horizontal wells, which will not affect normal drilling and completion operations.
