TS堵酸综合工艺技术的研究与应用

Study and Application of TS Plugging and Acidizing Comprehensive Technology

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 。

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.
