摘要
针对常规的调剖与酸化增注工艺在改善水井剖面中的弊端,在室内研究了TD耐酸堵剂,并对各项指标进行了评价,通过与CES 复合酸在水井上的综合应用,达到了控制高渗层,加强低渗层的目的,有效的改善了水井吸水剖面,取得了理想的增油效果,为非均质严重的油藏开发探索了一条新路。
Abstract
For solving serious , problems of the regular profile control and acid treatment in improving profile of the water injection well , TD acid-proof plugging agent was synthesized. The relative indexes was evaluated in the laboratory. According to the comprehensive application in water injection well with CES combination acid , the goal of controlling the high permeable formation , reinforcinglow permeable formation , effectually improving the water absorption profile and getting the satisfied result of increasing oil were achieved. Furthermore , This technology offered a new method for the oil-field developing of the serious anisotropism reservoir.
