【摘要】：本文将深抽井从泵挂深度上将深抽井分为两个部分,分别进行抽油杆、抽油泵、配套工具的优化优选,并通过现场实施效果进行工作制度的完善,形成机杆泵和制度相配套的油井深抽工艺技术。油井深抽目前没有详细的界定泵挂深度,从辽兴油气开发公司生产实际出发,并结合中深层油井深度定义,我们将泵挂在2000米以下的生产直井,定义为深抽井。并通过普通D级抽油杆强度计算,我们将这些深抽井分为两部分,一部分为泵挂在2000米至2400米的油井,这部分油井采用普通D级抽油杆可以基本上满足抽油杆强度要求,很少产生疲劳断脱；一部分为泵挂在2400米以下的油井,这部分油井采用普通D级抽油杆易发生疲劳断脱。在此基础上优化选择目前常用防偏磨工具、抽油杆类型、特种深抽泵以及其他的配套井下工具,并结合公司生产实际,优化选择工具配套。对于2400米以上的深抽井我们主要考虑的是油井防偏磨,通过优选防偏磨工具、特种深抽泵以及配套使用的井下工具最终形成以防偏磨配套为主的油井深抽工艺；对于泵挂在2400米以下的油井我们采用特种抽油杆代替普通的D级抽油杆,并配套防偏磨工具和泵效增高工具,提高油井抽油杆强度,提高油井泵效,保证油井产能、延长检泵周期的深抽工艺。通过两种防偏磨配最终形成适用于辽兴油气开发公司的油井深抽工艺技术。
[Abstract]:This paper from the deep well pump depth, deep well is divided into two parts, respectively, sucker rod pump, optimized matching tools, improve and carry through the field work system, the formation of deep pumping technology and machine rod pump system matching wells deep well pumping current. There is no detailed definition of pump depth, oil and gas from the Liao Xing development company production practice, combined with the deep depth of the oil well defined, we will pump hanging straight well under 2000 meters of production, defined as deep wells. And through the ordinary grade D sucker rod strength calculation, I have these deep wells is divided into two parts, one part is the pump hanging in the 2000 meters to 2400 meters of wells, these wells using ordinary grade D sucker rod can basically meet the requirements of sucker rod fatigue strength, rarely break off; as part of the pump hanging in the 2400 meters below the well, this part of the used oil Common grade D sucker rod is prone to fatigue fracture. Optimal selection of commonly used anti abrasion tool based on sucker rod type, special deep pumping and other downhole tools, and combined with the actual production, selection and optimization of tool matching. We mainly consider for more than 2400 meters deep wells is well anti eccentric, through the optimization of anti abrasion tool, special deep pumping and supporting the use of downhole tools, and ultimately the formation of deep pumping technology to prevent abrasion of the oil well pump for supporting the main; hanging in the 2400 meters below the oil level we use D special sucker rod instead of the ordinary sucker rod, and supporting the anti partial grinding tools and tools to improve the pump efficiency is increased, the oil pumping rod strength, improve the oil pump efficiency, ensure the production of oil wells, deep pumping technology prolongs the pump inspection period. By two kinds of eccentric wear prevention with final form suitable for Liaoxing oil and gas company's deep well pumping technology Art and technology.
