气动力深穿透增油增注技术研究与应用

锦州油田多数区块出现了胶质、沥青质、蜡质等物质析出堵塞油层现象,致使油层低渗,严重影响了油井产量。应用新型气动力深穿透增油增注技术,实现了油层深部复合解堵增油增注的目的。主要对技术原理、研制过程、室内实验和现场应用进行了综合评价,为油井解堵提供了新的思路。

Study and application on aerodynamic force and deep penetration to increase oil production and water injection

The precipitation of colloid,asphaltene and waxiness in most blocks in Jinzhou oil field blocks the reservoir,resul- ting in low permeability of reservoir and low output of oil wells.New technique of aerodynamic force and deep penetra- tion to increase oil production and water injection is applied to remove the blockage in the deep reservoir.The principles, manufacturing process,laboratory experiment and field ap- plication are evaluated comprehensively,which provides a new approach to relieve blockage in oil well.
