Research on drilling and completion stimulation technology in the middle and late stages of offshore oilfield
In order to improve the oil and gas recovery in the middle and late stages of offshore oilfields,this paper analyzes the main contradictions existing in the middle and late stages of offshore oilfields,and studies the principles and applicability of mainstream drilling and completion stimulation technologies.The results show that after the offshore oilfield enters the middle and late stage of production,the oil and gas production is less than expected due to the constraints of well groove,technology and economy,and it is necessary to extend the service life of the oil well through appropriate stimulation methods,so as to increase the oil recovery.Reasonable selection and adoption of high-efficiency utilization technology of well groove,multi-lateral well technology,hydraulic jet fracturing technology,extended-reach well technology,acidizing fracturing technology,gas lift technology and other stimulation technologies can achieve the purpose of increasing production and stabilizing production in the middle and late stages of offshore oilfields.
