ClO_2复合解堵工艺技术

COMBINATION PLUG REMOVAL TECHNOLOGY ABOUT ClO_2

介绍了 ＣｌＯ２复合解堵工艺的室内评价和适用范围，并对现场施工情况及应用效果做了分析。 ＣｌＯ２能使聚合物和细菌氧化分解，使原油粘度大幅度下降，流动性变好，对有机物造成的堵塞有较好的解堵作用，同时该复合解堵剂与硫化亚铁反应生成可溶性铁盐。当该剂与酸液结合应用时，还能解除由碳酸盐岩、粘土等造成的堵塞，具有一定的推广价值。

The laboratory evaluate and apply area about ClO2 was introduced, and the field construct effect was analyzed. The ClO2 agent can make polymer and bacterium oxidation and decomposed, so their viscidity was descended rapidly and fluidity was become well. The ClO2 agent has better plug remove to the organically plugging. The composite ClO2 agent reaction with ferrous sulfide can production solubility molysite. When it reaction with acidizing fluid, the com- posite agent can plug removal off carbonate rock and clay plugging material.
