百口泉采油厂机抽井采用的水基清防蜡剂溶液热洗清蜡方法,存在着部分井清蜡周期短、热洗清蜡成本较高及清、防蜡效果差等问题。为解决常规热水清蜡方法存在的问题,在对百口泉、夏子街油田油井结蜡状况及规律分析研究的基础上,百口泉采油厂进行了油基清防蜡剂的试验工作。并在油基清防蜡剂试验取得良好效果后,在百口泉采油厂所属机抽井进行了推广。一年期的统计和分析表明,油基清防蜡技术具有很好的油井清防蜡效果,降低了清防蜡施工费用,保证了百口泉采油厂机抽井的顺利生产。
There are some problems such as short cleaning cycle, high cost of hot cleaning and wax cleaning, poor cleaning and wax prevention effect, etc. In order to solve the problems existing in the conventional hot water waxing method, based on the analysis of oil well waxing conditions and regularities in Baikouquan and Xiazizi oilfields, the experiment of oil-based paraffin wax was carried out in the Baikouquan Oil Production Plant. And in the oil-based paraffin wax test to obtain good results, the machine in the Baikouquan pumping wells pumping machine was promoted. One-year statistics and analysis show that the oil-based paraffin removal technology has a good effect of oil well cleaning and wax removal, reducing the wax cleaning and waxing construction cost and ensuring the smooth production of pumping wells in the Baikouquan Oil Production Plant.
