集约化建井平台举升优化设计及配套技术
|
摘要
吉林油田近年来为应对低油价、产能建设投资高以及新区低品位资源难以效益动用的问题,在以新立地区Ⅲ区块为代表的常规低渗透油藏开展了集约化平台效益建产现场试验。在实施过程中,大井丛平台大斜度井数量增多、井身轨迹复杂,将会导致井下杆管磨损,成为制约平台井长期高效生产的主要问题。针对大斜度油井的井身轨迹特点,通过分析磨损原因和影响因素,确定了防磨举升优化设计思路,并通过降低摩擦系数、建立有效间隔、降低接触压力、降低接触频率等技术对策的实施,大幅度延长了平台井的检泵周期,实现了复杂井况条件下的长效举升。同时基于平台建井模式地面井位集中特点,创新采取一机多井非常规举升方式,现场试验了双驴头抽油机及液压抽油机,取得大幅度降低采油设备投资和生产能耗的较好效果,为低品位资源效益开发降低投资提供了技术支撑。
In recent years,in order to cope with the low oil price,high investment in capacity building and the difficulty in the utilization of low-grade resources in the new district,Jilin Oilfield has carried out intensive platform production and field trials in conventional low-permeability reservoirs represented by Block Ⅲ in Xinli District. During the implementation process,the number of large-angle wells on the large wells platform increases,and the well trajectory is complicated,which will lead to the wearing of the downhole rods and becomes the main problem that restricts the long-term efficient production of platform wells. Aiming at the characteristics of wellbore trajectory of high-angle oil wells,through the analysis of wear causes and influencing factors,the design concept of anti-wear lifting is determined,and the technical countermeasures such as reducing friction coefficient,establishing effective interval,reducing contact pressure and reducing contact frequency are determined. The implementation has greatly extended the pump inspection cycle of the platform well and achieved long-term lift under complex well conditions.At the same time,based on the characteristics of the ground well location of the platform construction mode,the innovative multi-well unconventional lifting method was adopted, and the double-headed pumping unit and hydraulic pumping unit were tested on site,which greatly reduces the investment in oil production equipment and energy consumption,and provides technical support for low-grade resource efficiency development and investment reduction.
