Anti-collision Optimization Design Technology of Large Infill Cluster Well Group in Bohai Sea Artificial Island B

Wenhao XU


In view of the difficulty and low efficiency in the design of collision prevention and obstacle avoidance in the large-scale infilling adjustment of the cluster well group in Bohai Sea artificial island B, based on the analysis of the overall situation and characteristics of the infilling well, accurate calibration of already drilled data, and using industry standard principles for cluster well platform optimization and anti-collision design, develop specific procedures for designing anti-collision tracks for large-scale infill wells, form anti-collision optimization design methods, optimize drilling sequence, slot matching relationship and anti-collision track design parameters. The track design and anti-collision analysis of 45 infill wells have been completed in the limited platform space through multiple slot adjustment and track optimization.The minimum value of the separation coefficient of each well meets the requirements of the industry standard minimum limit of 1.5, and 70% of them are concentrated above 1.7, which reduces the risk of anti-collision as a whole.The results show that the anti-collision optimization design technology of large-scale infill cluster well group can effectively solve the anti-collision design problem of large-scale infill adjustment of cluster well group, and help to improve the design quality and efficiency.
