优化清蜡工艺,减少作业时间是提升油井产量的重要措施。传统的清蜡方式存在能耗高、二氧化碳排放量大、入井液多、清蜡不彻底、成本高等缺点。分析传统清蜡工艺影响原油产量的原因,研制了新型CNG自控清蜡车,生产蒸汽进行清洗。采用CNG为燃料,设计了先进的控制系统,使油井清蜡工艺达到安全、节能、环保及精细化的要求,提高了经济效益。 Optimization of waxing process, reduce operating time is an important measure to improve oil production. The traditional method of waxing has the disadvantages of high energy consumption, large amount of carbon dioxide emissions, more fluid into the well, incomplete waxing and high cost. Analysis of the traditional waxing process affect the production of crude oil, developed a new type of CNG self-cleaning wax car, steam production for cleaning. Using CNG as fuel, an advanced control system has been designed to make the well de-waxing process meet the requirements of safety, energy conservation, environmental protection and refinement, which has raised economic benefits.
