Analysis and application of slot replacement technology in Bohai Oilfield
Bohai Oilfield is an important offshore energy base in China,and adjustment well drilling opera-tions are an effective means and key support for increasing storage and production in Bohai Oilfield.Efficient utilization of slot resources is an important way to achieve cost reduction and efficiency increase in adjustment well drilling.In response to the increasing number of low production and low efficiency wells in Bohai Oilfield and the increasing scarcity of slot resources,the process and method of slot replacement have been developed by analyzing the mature sidetracking technology in Bohai Oilfield and conducting analyzation slot replacement technology.The on-site implementation results indicated that this technology could effectively reduce the diffi-culty and cost of drilling operations,and the reserved empty slots could be used as the needs for subsequent oilfield adjustment wells,providing new ideas and guidance methods for efficient utilization of slots in Bohai Oilfield.
