以“延长油井检泵周期,提高抽油泵效”为目的,持续推进“一井一法一工艺”精细管理法,开展“重点区块,高产井、高频井、低产低效井”专项治理,按照“突出重点、综合治理”的原则,推广“管杆调整更换、参数优化、五防配套、井筒净化”等配套工艺,同时加大新工艺应用,不断提高井筒管理水平。本文在现场调查的基础上,主要针对油田在开发过程中,因采油井井筒结蜡、结垢、腐蚀、出砂、偏磨及原油脱气等原因导致采油井管、杆、泵故障频繁,泵效低下,检泵周期缩短,开发成本增加等问题,从以下三个方面进行综合治理以改善目前现状:(1)通过对油井进行参数优化、加深泵挂、措施增产、井筒净化开展专项治理,提高泵效。(2)通过对偏磨井、结蜡井、结构井、漏失井、断脱井的综合配套治理,延长检泵周期。(3)加强新工艺新技术应用,提高工艺管理水平。2012年通过以上三点的现场实践,冯地坑作业区在井筒综合治理方面取得了一定效果,并且为今后的继续治理提供了措施依据和经验基础。 To “extend the oil well inspection pump cycle and improve pumping efficiency” for the purpose of continuing to promote “a well of a method of a process ” fine management method to carry out “key blocks, high production wells, high frequency wells, low yield We will promote the application of new techniques and technologies in accordance with the principles of ”highlighting key points and comprehensive management “, promoting ”pipe rod adjustment and replacement, parameter optimization, five prevention and matching, wellbore purification " and other supporting technologies, Continuously improve the wellbore management level. Based on the field investigation, this paper mainly focuses on the frequent failure of oil well pipes, rods and pumps during oilfield development due to waxing, fouling, corrosion, sand production, partial wear and gas degassing of oil well, Pump efficiency is low, check the pump cycle is shortened, the cost of development increases and so on, from the following three aspects of comprehensive management to improve the current situation: (1) through the optimization of the well parameters, deepen the pump hanging, measures to increase production, wellbore purification special treatment, Improve pump efficiency. (2) Extend the inspection pump cycle by comprehensively supporting the partial wear well, the wax well, the structural well, the lost well and the broken well. (3) Strengthen the application of new technology and new technology to improve the level of process management. Through the above-mentioned three-spot practice in 2012, the Fengdikeng operating area has achieved some results in the wellbore comprehensive management, and has provided the measure basis and the experience basis for the continued management in the future.
