Analysis of Gas Injection Technology for Secondary Development of XH27 Block Reservoir
In the process of oil field development,secondary development is an important method that has received widespread attention.Gas injection technology is one of the key technologies in secondary development,which can increase formation pressure,push oil towards the wellbore,improve oil recovery conditions,thereby enhancing oil recovery rate and production efficiency.This paper focuses on the primary contradictions encountered in the secondary development of the XH27 block oil reservoir,with a particular emphasis on gas injection technology.It proposes an optimized gas injection column technique and evaluates its on-site application effects.Firstly,the paper outlines the primary development status of the XH27 block oil reservoir,analyzing the challenges and issues faced during the initial development phase.Subsequently,it presents solutions to problems such as water flooding in oil wells and declining block production by advocating the use of gas injection technology.Key components of this approach,including insulation methods and optimized gas injection column techniques,are elaborated upon in detail.Finally,through on-site implementation and effectiveness evaluations,the paper validates the efficacy and feasibility of the proposed gas injection technology for the secondary development of the XH27 block oil reservoir,offering valuable insights for further field development.
