低渗透油藏历经二十多年的开发,受注采井距大、储层污染等因素制约,造成地层能量差,注采两难问题日益突出,严重影响油水井能力的发挥。尽管近年来,部分油井动液面仍持续下降,注水不见效,导致注水效果差,影响油藏开发水平。因此采油厂从大局出发,积极转变观念,以增强油田稳产基础为目标,以单元目标化管理为总抓手,地质、工艺配套联动,各项目组成员密切结合,以提高低渗油藏油水井能力为中心,强化油水井治理,努力提升低渗油藏开发管理水平。
After more than 20 years of development, the low-permeability reservoirs have been constrained by such factors as large injection-production well spacing and reservoir contamination, resulting in poor formation energy. The problems of injection and mining have become increasingly prominent, seriously affecting the ability of oil and water wells. In recent years, some oil wells still continued to decline in liquid level, water injection is not effective, resulting in poor water injection, affecting the level of reservoir development. Therefore, from the overall situation, the oil extraction plant actively changed its mindset, aiming at enhancing the stable production base of the oilfield. With the target management of the unit as the general starting point, the geology and technology were coordinated with each other and the project team members were closely integrated to improve the oil and water wells Ability as the center, strengthen the management of oil and water wells, and strive to enhance the development and management of low permeability reservoir.
