Description

一种摇摆式双井抽油机 技术领域  Swing type double well pumping unit
本发明涉及一种应用于油田油井的摇摆式双井抽油机, 也涉及一种同轴 联接多点驱动双排列油井抽油机。  The invention relates to a swing type double well pumping unit applied to an oil field oil well, and also relates to a coaxial joint multi-point driving double array oil well pumping unit.
背景技术 Background technique
现有的油井, 大多数采用一机一井配置, 少数采油双井一机配置, 在高 原沟壑地带, 因平地稀缺, 多采用定向斜井构成排列式井, 人工岛上土地资 源有限, 多采用排井, 采油一机双井乃至多井抽油可大大降低能源消耗, 降 低采油成本, 节约设备投资。 各油田公司积极推广占地面积少、 利用效率高 的丛式井组应用, 取得明显效果, 丛式井是指在一个井场或平台上, 钻出若 干口甚至上百口井, 各井的井口相距不到数米, 各井井底则伸向不同方位。  Most of the existing oil wells are equipped with one machine and one well, and a few oil and gas are equipped with one machine. In the plateau gully zone, due to the scarcity of flat land, the inclined wells are often used to form the aligned wells. The artificial island has limited land resources. Draining wells, oil recovery, double wells and even multi-well pumping can greatly reduce energy consumption, reduce oil production costs, and save equipment investment. Each oilfield company actively promotes the application of cluster well groups with small floor space and high utilization efficiency, and achieves obvious results. Cluster wells refer to drilling a number of ports or even hundreds of wells on a well site or platform. The wellheads are less than a few meters apart, and the well bottoms are extended to different orientations.
我国现行的抽油机标准 SY/T5044-2003《游梁式抽油机》是参考美国石油 学会 1993年颁布 API spiel IE《抽油机规范》基础上结合现实生产和使用情况 修订完成的, 减速机额定扭矩 M, 悬点最大载荷 P, 最大冲程 S是抽油机的 3 个主要参数, 采用 PS/M=C (常数:), 随着生产条件的变化, 比如抽油杆直径、 泵径、 冲次、 冲程、 下泵深度等改变, C值发生改变, 三种参数按不同等级 的搭配形成了 77 (API spicllE) 种和 28种 (SY/T5044-2003)不同规格的抽油 机(C值通常在 3-12间), 上述各型号均为单机单井结构, 仅一侧抽油, 另一 侧消耗能源, 使抽油机单位功率价格大, 抽油效率低下, 与低碳经济相悖。  China's current pumping unit standard SY/T5044-2003 "Wall beam pumping unit" is based on the revision of the API spiel IE "pumping machine specification" issued by the American Petroleum Institute in 1993, combined with the actual production and use of the revised, deceleration Rated torque M, maximum load P of the suspension point, maximum stroke S is the three main parameters of the pumping unit, using PS/M=C (constant:), with changes in production conditions, such as sucker rod diameter, pump diameter The C value changes when the stroke, stroke, and pump depth change. The three parameters are matched with different grades to form 77 (API spicllE) and 28 (SY/T5044-2003) pumping units of different specifications ( The C value is usually between 3 and 12). Each of the above models is a single-machine single-well structure, which only draws oil on one side and consumes energy on the other side, so that the pump unit has a large unit power price, low pumping efficiency, and low-carbon economy.

The technology involves a speed reduction mechanism, a speed reduction belt, and a power chain. Wheels, driven sprocket, power chain, driven chain, and reversing links are all steel parts. Every action needs to be turned, there is rigid wear of steel parts, and the average pumping speed per minute is 3- Four calculations, millions of times of reversing rigid uninterrupted friction every year, the existing materials are difficult to meet such use conditions, which will inevitably lead to frequent shutdowns, replacement of wearing parts, and increased operating costs.
中国专利 200510046026.0, CN1664305A公开了一种 "电子-电气-机械一 体化曳引式抽油机", 省去了减速机, 效率可达 90%以上, 冲程、 冲次无级可 同歩无齿轮曳引机, 运行精确平稳, 直接拖动、 低速大转矩、 同等体积 效率大等优越性能, 无功耗停车自闭等独到的特点, 其风险为连续工作制全 天候露天作业, 从北到南气候变化环境温度海洋上的潮湿露点等对控制系统 电子元件功能稳定性和寿命的影响, 尚无数据。 但存在的不足是: 不能用于 双井抽油。 需要与抽油杆一端相匹配的平衡重, 即当抽油机一端悬挂的重量 为 18吨时, 另一端也需大约 18吨的平衡配重。 仅一端做功, 另一端无功损 耗。 机头伸缩机构由机架上部的导轨、 手柄、 螺杆组成, 承载提升物一端为 悬臂端, 加工精度要求高, 导轨螺杆需要加油润滑, 制造、 安装成本高。 Chinese Patent No. 200510046026.0, CN1664305A discloses an "electronic-electric-mechanical integrated traction pumping unit", which eliminates the speed reducer, the efficiency can reach more than 90%, and the stroke and the stroke can be stepless.

However, the shortcomings are: Can not be used for double well pumping. A counterweight that matches the end of the sucker rod is required, that is, when the weight of one end of the pumping unit is 18 tons, the other end also requires a balance weight of about 18 tons. Only one end works, and the other end loses power. The telescopic mechanism of the head is composed of the guide rail, the handle and the screw at the upper part of the rack. The one end of the load carrying object is a cantilever end, and the processing precision is high. The guide screw needs to be lubricated and lubricated, and the manufacturing and installation cost is high.

The hydraulic cylinder piston rod is composed of a hydraulic pump and a motor. Provides power to control the reciprocating motion of the hydraulic cylinder piston rod through the reversing valve. The machine has the following deficiencies: 1) Hydraulic cylinder piston rod and commutator need to be replaced frequently under continuous working conditions; 2) Fuel tank, hydraulic pump, hydraulic cylinder piston rod rubber seal is easy to aging, oil leakage and pressure under open air operation Unstable; The organization has one well that cannot be operated, shut down, and affects efficiency when one of the wells is overhauled; the mechanism uses four concentrically fixed equal-phase arc-shaped segments with large dimensions, which is time-consuming and labor-intensive to install and process.
中国专利 CN201092849Y公开的一种链条式双井抽油机, 采用的链条驱 动机构, 减速机的传动链条经链轮传动带动齿轮箱内的链轮上的驱动链条再 带动卡在上下导轨内的连接架水平运动, 实现了双井抽油, 但存在明显不足: 1)该机构涉及减速机同时还另增加有齿轮箱,存在机械传动效率低下, 因长期 需要油润滑,时常出现漏油想象, 2)传动链条和驱动链条两种链条和多个链轮、 因传动需要链条驱动还是链条, 对链条的质量要求高, 长期处于野外工作环 境下, 沙粒等灰尘附着表面, 影响使用寿命, 3)驱动链条经链条连接销轴接的 连接架需卡在上下导轨做水平运动, 每个冲程一次摩擦, 金属间的摩擦滑动, 很容易磨损发热, 加速变形损坏。  Chinese patent CN201092849Y discloses a chain type double well pumping unit, which adopts a chain drive mechanism.

The horizontal movement of the frame realizes the double well pumping, but there are obvious deficiencies: 1) The mechanism involves the reducer and the gearbox is added at the same time. The mechanical transmission efficiency is low. Due to the long-term need for oil lubrication, oil leakage imagination often occurs. 2 Drive chain and drive chain two chains and multiple sprockets, chain drive or chain required for transmission, high quality requirements for chain, long-term in the field working environment, sand and other dust attached to the surface, affecting the service life, 3) The connecting frame of the driving chain through the chain connecting pin shaft needs to be stuck on the upper and lower rails for horizontal movement, and each stroke is rubbed once, and the friction between the metals slides, which is easy to wear and heat, and accelerate deformation and damage.

The following deficiencies exist: Hydraulic cylinder plunger, oil The tank, overflow valve and stroke control slide valve need to be replaced frequently under continuous working conditions; the fuel tank, hydraulic pump and hydraulic cylinder piston rod rubber seal are easy to age and leak under the open air operation, making the system pressure unstable; When the well is overhauled, the associated cluster wells are all shut down; the stroke height and the distance between the adjacent two wells are difficult to coordinate with the stroke control slide valve. When the stroke requirement is large, the well spacing is near, it cannot be equipped; the stroke height and the adjacent two ports The spacing of the wells is difficult to coordinate with the stroke control spools. When the stroke requirements are large, the well spacing is near and cannot be equipped.
