高渗透大孔道地层封堵技术研究

A STUDY ON PLUGGING TECHNIQUE IN HIGH PERMEABLE MACRO PORE PATH

针对中原油田开发现状， 研制了一种新型的有机无机复合堵剂———ＪＴＤ， 对其性能进行了全面的评价。结果表明， ＪＴＤ 堵剂成胶性能好、封堵强度高、耐冲刷性能好； 尤其适应于封堵高渗透、大孔道地层， 且现场施工简便、施工用量少、成本低， 取得了很好的应用效果。

This paper introduces a new type of organic inorganic complex plugging agent JTD, which is applicable for Zhongyuan Oil Field. The apprasal of its performance indicates that JTD plugging agent has a nice performance of forming colloid, high strength of plugging and nice performance of flushing resistance. It is especially suitable for plugging high permeable,macro pore path formations and convenient for field operation with a small amount of volume and a low cost, obtaining a good effect.
