提高油层近井地带处理效果的有效方法

Efficient methods of improving reservoir treatment effects in the near wellbore area

油田在开发生产过程中 ,油层近井地带产生损害与堵塞 ,严重影响油井产量 ,甚至使油井不出油。矿场上沿用的解堵措施 ,由于原理及适应性所限 ,处理效果不够理想。分析研究认为 ,改善油层近井地带处理效果的方向是对油层实施复合处理技术。文中以吉林油田为例 ,介绍物理振动法处理油层与化学法处理油层相结合技术 ,矿场实验表明 ,有效率、有效期、单井增油、经济效益均有大幅度提高。需指出的是 ,复合技术不是几项单一技术的简单迭加。根据技术原理和油层情况 ,通过试验研究 ,实现技术优势互补 。

In the process of oil production in the oilfields,the pollution of near well-bore area and plugging in reservoir are commonly existing now.They influence production of oil-wells,even can′t product oil.Because of the principle of plug removal measure and its adaptability are limited,reservoir treatment effects aren′t ideal.In order to improve reservoir treatment effects in the near wellbore area,this peper presents a new reservoir treatment method which is the combination technology of physical vibration method and chemical method.The field tests show that the efficiency,the efficient periods,single-well stimulation and economic benefit are enhanced.Meanwhile,the paper points out that the combination technology is not simple adds of several single technology.Through research and field application of the new reservoir treatment technology,stimulation effect and good economic benefit are obtained
