油井套掺泵下自动混合工艺技术的应用

Well casing blending pump-down automatic blending technology and its site effect & evaluation

油井降粘、降凝及清防蜡通常采用向井内加注化学药剂 ,如何实现化学药剂在井下与原油充分混合是影响加药效果的重要因素。现文介绍一种油井套掺泵下自动混合工艺技术 ,包括工艺技术原理、管柱结构。

Adding & injecting chemicals to the well is usually used to lowing well viscosity & condensation and cleaning & inhibiting. It is an important factor how to realize the full blending chemicals with crude oil. This paper introduces a well casing blending pump down automatic blending method, including its technical principle, pipe strings structure, technical features and field applied condition.
