提高低液高气油井作业开井成功率技术

摘要

With the continuous development of oilfield, there are more and more stripper wells, and the wellbore is more and more dirty, leading to improper operation of the oil well which needs to be rectified repeatedly and even reworking. As a result, the one time success rate is low and it is unfavorable to reservoir protection. Through long-term research and experiment for many times, the relatively mature technology to improve the one time success of the low-liquid high gas oil well based on anti-fouling slotted gas anchor is formed and the effect is obvious.%随着油田的不断开发，低产井越来越多，井筒越来越脏，造成油井作业后凡尔工作不正常，导致开井后需反复整改、甚至需返工才能正常，导致一次成功率低，同时还不利于油层保护。通过长期研究和多次实验，形成了以防污割缝气锚为主的比较成熟的提高低产高气油井一次作业成功率的技术，效果明显。
