国内外原油开采实践证明,有杆抽油具有综合成本低、功率消耗小,经济效益高,安全可靠,便于维修、检测,有利于实现油井自动化控制等优点。更重要的是有杆抽油泵在国外经过几十年的不断改进发展,已日趋完善。在有杆抽油油井占机采油井99.4％的我国,近年来对抽油泵的引进、制造等方面给予了一定重视,因而有较快发展。但与国际先进水平还有
The practice of crude oil exploration at home and abroad proves that sucker rod sucker rod has the advantages of low overall cost, low power consumption, high economic benefit, safe and reliable, easy maintenance and testing, and is conducive to realizing automatic control of the well. More importantly, the sucker rod pump has been improving continuously after decades of continuous improvement and development in foreign countries. In our country, which has 99.4% oil wells occupied by sucker-rod pumping wells, we paid more attention to the introduction and manufacture of sucker-rod pumps in recent years, and thus have a rapid development. But with the international advanced level there
