重庆气矿高压采气管线堵塞分析及应对措施
An analysis and countermeasures of high-pressure flow line clogging at Chongqing gas field
摘要
Abstract
In recent years, to accelerate production and reduce costs, the Chongqing Gas Field of PetroChina Southwest Oil ＆ Gasfield Company deployed some development wells and constructed some high-pressure flow lines and realized the un-manned stations. However, at the early stage the high-pressure flow lines are often blocked in winter because of downhole pol-lutants, complicated terrain and high operation pressure and low temperature of the land, etc. This influenced the normal pro-duction of a gas well. Therefore, the Chongqing Gas Field performed a further study into various factors which have caused the pipeline clogging such as the terrain, pollutants or effusion, gas components and working conditions, ground temperature, de-livery pressure and temperature, insulation materials, diameter of high-pressure flow lines, and flow velocity. Besides, some other anti-clogging countermeasures are proposed, including downhole throttling, adding inhibitor, electric heating, heat insu-lating measure and optimal allocation of parameters. These measures can improve the high-pressure gas production and ensure the failure-free operation of these lines.关键词
