风城采油二站在热采过程中多次发生套管头漏、羊角阀漏等问题,造成井口污染问题,给安全生产、环保带来了困难和压力。本文首先通过对问题井井型、钻井单位、套管头厂家、投产年份及生产轮次、注汽参数、整改轮次等几方面分析,总结了采油二站问题井的主要特点;试验了通过封隔器封堵试验及关羊角阀试注汽试验治理羊角阀漏问题井的可行性,验证了可以通过关羊角阀注汽成功治理羊角阀漏井的方法。 In the process of heat recovery, the second station of Fengcheng Oil Production Station repeatedly encountered such problems as casing head leakage and horns valve leakage, resulting in the problem of well head pollution and brought difficulties and pressure to safety production and environmental protection. Firstly, this paper summarizes the main features of the wells in the second oil recovery station by analyzing the well types, drilling units, casing manufacturers, year of production, production cycle, steam injection parameters and rectification rounds; The packer plugging test and the shut-off valve test steam injection test to deal with the feasibility of the valve shut-off valve problem, verified that the shut-off valve steam injection can successfully manage the shut-off valve leaky well method.
