萨莫特洛尔油田AB(4－5)层已处于晚期开发阶段，大部分生产井特点是低产、高含水90％～98％，处于盈利开采边缘。在这种条件下提高采油效率就需要减少水淹井伴生水产量以确保堵水工作顺利开展，还必须了解剩余储量结构特点、选井标准、类似措施的严格设计方案。本文阐述了这种情况下的开发特点和堵水方法。 The AB (4-5) layer of the Samoterlor field has been in the late stages of development, and most of the production wells are characterized by low yields and high water cut levels of 90% to 98% at the margin of earnings exploitation. Under such conditions, it is necessary to reduce the associated aquatic production in the water flooding wells to ensure the smooth operation of the water blockage. It is also necessary to understand the structural features of the remaining reserves, the well selection criteria and the strict design of similar measures. This article describes the development features and methods of plugging in this situation.
