摘要
在油田开发过程中,二次开发是一种重要的方法,受到了广泛的关注.注气技术是二次开发中的关键技术之一,能够增加地层压力、推动油向井眼移动、改善采油条件,从而提高采收率和增产效果.文章针对XH27 块油藏二次开发中的主要矛盾,以注气工艺技术为重点,提出了一种注气管柱优化技术,并进行了现场应用效果评价.首先,对XH27 块油藏的一次开发情况进行了概述,分析了一次开发阶段存在的问题和挑战;其次,针对油井水淹、断块产量递减等问题,提出了采用注气工艺技术的解决方案,并详细描述了隔热方式、注气管柱优化技术等关键内容;最后,通过现场实施情况和效果评价,验证了提出的注气工艺技术在XH27 块油藏二次开发中的有效性和可行性,为油田的进一步开发提供了重要参考.
Abstract
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.
