Drilling Completion Technologies of Sinopec Overseas Oilfields: Status Quo of Technology Development Suggestions

The yearly oil gas production from Sinopec overseas fields has exceeded 4 000×104 t,which has become an important guarantee for the safety of oil and gas energy supply in China.Drilling completion engineering plays a key role in achieving Sinopec overseas oil and gas exploration and development targets.The continual fluctuation within the international oil and gas market environment and the new Sinopec overseas resources distribution pattern have put forward new requirements for the development of drilling completion engineering.Therefore,this paper summarizes primary progress in drilling completion engineering achieved in Sinopec overseas fields in past years,and it analyzes existing problems and challenges.Finally,it proposes development suggestions.It proposes to take the strategy of continuously promoting technology innovation to deal with oil price fluctuations,and to accelerate the development of drilling completion technology and realize potential resource tapping and efficiency improvement by tackling "bottlenecks",integrative applications,basic research and technology development of reserves,and the construction of a technical management system.
