| 摘 要： | 粉煤灰调剖技术是解决浅层油藏渗流矛盾的重要技术,但存在成本高、处理半径小、压力上升快、有效期短等问题。为了利用粉煤灰成本低廉,热稳定性好等特点,对常规粉煤灰调剖体系进行了改进,改进后体系具有非固化、低成本、大剂量注入、封堵强度高等优点,适用于冀东油田高浅北区地下大孔道发育的注水井深部调剖。

| Abstract: | Conventional flyash profile control technology was an important technology which resolved seepage illogicality.But the technology took on some problems for high cost,short disposal radius,press rapid-rising,short period of validity and so on.Improving on the conventional flyash profile control technology,in order to making use of the good qualities of low cost and speciality stabilization in high temperature condition,the system was improved which had good qualities of non-solidification,low cost,being infused by large volume,and avoiding fleeing in deep stratum.The technology was applied to block up the big routeway of water drill in high,light and north area. |
