| 摘 要： | 根据孤岛油田的地质特点和长期注水开发生产历程,分析了孤岛油田大孔道形成原因,以及大孔道在注水过程中所呈现的特征。在室内对各种类型堵剂进行筛选及性能评价,确定了以HD-1无机颗粒型+LWSD-1木质素磺酸钙冻胶型复合堵剂调剖体系封堵大孔道,并且详细提出了调剖封堵大孔道选井选层原则及其调剖封堵对策。自1997年以来调剖封堵大孔道58井次,对应油井累计增油57383t,减水71361m3,投入产出比1:2.37

| Abstract: | According to the geological characteristics and the procedure of long-term water injection in GuDao oilfield, this paper analyze the forming mechanism of big pore path, and it's performing characteristics in water injection well. Many kinds of water plugging agent were screened and evaluated in the lab., finally determined to choose HD-1 inorganic particle style and LWSD-1 lignin sulfate calcium compound to do it. A detail principal was introduced in choosing well, choosing layer and profile control plugging method. Since 1997, 58 wells were disposal, total increase oil 57383t, decrease water 71361m3, the input-output ratio is 1:2.37. |
