姬塬油田吴420区主要开发长6油藏,储层孔隙度发育中等,属低渗透储层。随着开发年限的增长,油藏管理问题逐渐暴露。目前共有见水井145口,日影响油量131t,2011年新增见水井24口,损失油量62t,受剖面水驱不均的影响,部分注水井层间吸水不均造成对应油井含水上升,保持老井稳产和降低自然递减成为主要攻克目标,因此水井治理对油田稳产显得尤为重要。2011年实施精细注水管理、水井酸化增注、水井调剖、分层注水等一系列措施,本文主要是对以上水井实施的措施效果进行分析总结,对提高油藏的开发水平及丰富低渗透油田的开发经验,具有实践意义。 Wu 420 area in Jiyuan Oilfield mainly develops Chang 6 reservoir with medium developed porosity and low permeability reservoir. With the development of the growing number of years, reservoir management issues gradually exposed. At present, there are 145 wells, affecting 131 tons of oil. In 2011, 24 wells were newly added and 62 tons of oil were lost. Affected by the uneven waterflooding of the section, uneven water absorption among some injection wells resulted in the corresponding rise in water content of wells, Maintaining the stable production of the old wells and decreasing the natural decline is the major objective of the project. Therefore, it is particularly important for the well management to stabilize the oilfields. In 2011, a series of measures such as fine water injection management, acidizing and recharging wells, profile control of wells and stratified water injection were carried out. This paper mainly analyzes and summarizes the effect of measures implemented in the above water wells. It is of great significance to improve the development level of reservoirs and enrich low permeability oil fields The development experience, with practical significance.
