Description
一、技术领域1. Technical field
本实用新型涉及石油开采、煤层气开采设备领域，尤其是涉及一种丛式井增程式抽油机。The utility model relates to the field of oil exploitation and coal bed gas exploitation equipment, in particular to a cluster well extended-range pumping unit.
二、背景技术2. Background technology
近年来我国丛式井在油气田、煤层气开采中的应用得到了快速的发展。丛式井抽油技术的特点：可满足钻井工程上某些特殊需要，如制服井喷的抢险井；可加快油气田勘探开发速度，节约钻井成本；有利于节约油田占用土地面积，更好的保护耕地和节约能源；便于完井后油井的集中管理，减少集输流程，节省人、财、物的投资，进而提高低渗透油气田开发经济效益等等。但是丛式井的机械采油技术仍然非常落后，至今还没有一种可行的丛式井抽油机。目前油田和煤层气开采领域仍然使用单机单采的开采模式，油井的设备投入和正常的运行费用很高，导致油井生产的经济效益已经很低，有的甚至接近于零。主要原因就是单机单采已经不能满足多井共享平台的丛式井特点。In recent years, the application of cluster wells in oil and gas fields and coalbed methane exploitation has developed rapidly in my country. The characteristics of cluster well pumping technology: it can meet some special needs in drilling engineering, such as emergency wells for subduing blowout; it can speed up the exploration and development of oil and gas fields, and save drilling costs; it is conducive to saving the land area occupied by oil fields and better protecting cultivated land and save energy; facilitate the centralized management of oil wells after well completion, reduce the gathering and transportation process, save investment in manpower, money, and materials, and then improve the economic benefits of low-permeability oil and gas field development, etc. But the mechanical oil recovery technology of cluster wells is still very backward, and there is no feasible cluster well pumping unit so far. At present, oilfields and coalbed methane mining fields still use single-machine single-production production mode. The equipment investment and normal operation costs of oil wells are very high, resulting in low economic benefits of oil well production, and some are even close to zero. The main reason is that stand-alone mining can no longer meet the characteristics of cluster wells that share platforms with multiple wells.
