吴起作业区开发区块大部分属于低渗透注水开发油藏,随着油田开发的不断深入,注水井欠注问题日益突出。本文从系统配套、井筒治理和油藏治理三方面入手,分析引起欠注的因素,提出“整体优化、单点消欠及加强管理”的治理对策,并对治理效果进行评价。 Most of the blocks in the Wuqi operation area belong to low permeability waterflooding reservoirs. With the continuous development of oilfields, the problem of underfilling injection wells has become increasingly prominent. This article starts with three aspects of system support, wellbore management and reservoir management, analyzes the factors that cause underfill, and proposes the governance strategy of “overall optimization, single point elimination and strengthening management”, and evaluates the governance effect.
