目前文209、38、234及文276段块的抽油机井清蜡方式主要依赖于热洗和加清蜡剂,而热洗则是清蜡最彻底,最有效果的手段,抽油井机热洗一般是用热水作为介质,经过对管柱加热,对井筒内的抽油管柱用热水循环,而达到熔化蜡块并携带蜡质返出地面的效果。洗一方面可以清除井筒管杆的结蜡及脏物,另一方面也不同程度影响油产产量,个别井影响产量周期很长,以地层均速产液不受影响、井筒清蜡彻底、排蜡彻底、入井液不伤害油层,少影响产量为目的,对热洗工作进行了改进,努力减少原油损失。
At present, paragraphs 209, 328, 234 and 276 paragraphs block pumping well decontamination mainly depends on the hot wash and add the wax, and hot wash is the most thorough and most effective means of wax removal, pumping machine heat Washing is generally hot water as a medium, after heating the column, the wellbore pumping string with hot water circulation, and to achieve the melting wax block and bring the wax back to the ground effect. Washing on the one hand can remove wellbore pipe rod wax and dirt, on the other hand also affect oil production to varying degrees, individual wells affect the production cycle is very long, the formation is not affected by the average velocity of liquid production, Wax thoroughly, into the fluid does not hurt the reservoir, less impact on production for the purpose of the hot wash work has been improved, and strive to reduce the loss of crude oil.
