在原油粘度大、产液含水低和环境温度较低时应用现有稠油举升工艺会造成油井无法正常生产,严重时还会引起抽油杆断脱。为此,研制了新型逆向抽稠泵。该泵主要由泵筒、柱塞和换向阀组成,其主要特点是油管进油套管出油,靠油管掺水和液柱压... 在原油粘度大、产液含水低和环境温度较低时应用现有稠油举升工艺会造成油井无法正常生产,严重时还会引起抽油杆断脱。为此,研制了新型逆向抽稠泵。该泵主要由泵筒、柱塞和换向阀组成,其主要特点是油管进油套管出油,靠油管掺水和液柱压差解决稠油井常见的光杆缓行问题,对稠油的适应性较强;柱塞上没有阀门,靠换向阀实现产液从油管到套管的换向。该泵在现场应用12口井,成功率100%,平均单井日增液21m3,日增油1.7t。 展开更多

It is a component of a pumping unit. When the pumping unit' s polish rod moves up and down repeatedly, the stuffing box can play a role in sealing so as to prevent the liquid in the oil well flom leaking. However, there can be friction, called "eccentric wear" , between the polish rod and stuffing box for some reason during their relative movements. This paper proposed specific solution through analyzing this phenomenon. 展开更多
