Description

一种石油开采用高精度提捞式抽油机 技术领域
本发明涉及石油开采设备，具体为一种石油开采用高精度提捞式抽油机。
背景技术
目前，石油开采用提捞式抽油机体积过于庞大，一般都有两个安装基础，一个用于井口对准井架的安装基础，一个用于提升卷扬机的安装基础，两基础之间需保持较长一段距离，目的是为了尽量减小柔性抽油杆排绳时出现的磨损损伤，但仍存在如下不足之处：1、柔性抽油杆排绳时的磨损损伤仍无法克服，长时间使用后不仅影响抽油精度，而且易在地面形成油线，造成环境的污染；2、两个安装基础的结构设计占用平面空间大，空间利用率差，而且敌方卫星上易侦查，隐蔽性较差，存在安全隐患；3、柔性抽油杆外露部分过长，抽油数据测量误差较大，而且存在材料及能源的浪费。
发明内容
本发明为了解决现有提捞式抽油机存在抽油精度差、易污染环境、空间利用率差、安全隐患大且浪费较严重的问题，提供了一种石油开采用高精度提捞式抽油机。
本发明是采用如下技术方案实现的：一种石油开采用高精度提捞式抽油机，包括井口密封器和固定在井口周围的抽油机架，抽油机架的上方设置有导轨架，导轨架与抽油机架之间设置有抽力传感器，且抽油机架的四个角部固定有紧贴导轨架四个角部的角钢状限位板，导轨架上设置有两根前后分布且左右放置的导轨，导轨上设置有沿其左右移动的提油小车，提油小车上设置有卷筒和减速制动电机，减速制动电机的输出轴与卷筒的轴心相连；抽油机架上设置有前后分布的对中机构和驱动机构；对中机构包括对中底座，对中底座上固定有连接 支架，连接支架上设置有两个左右分布且柱面紧贴的对中滚轮，两对中滚轮的柱面上开有位置对应的环状半圆槽，两环状半圆槽的紧贴处围成一个圆形的柔性抽油杆限位口，柔性抽油杆限位口、井口密封器及卷筒前端的任一螺旋槽上下位置对应；驱动机构包括固定在抽油机架上的驱动支座，驱动支座上固定有上端部位于卷筒螺旋槽内且与卷筒螺旋槽配合的驱动杆。
该结构设计中提油小车在驱动机构的作用下左右移动，实现了缠绕在提油小车上的柔性抽油杆离开卷筒后始终与井口对中，柔性抽油杆的抽力是没有分力和弯曲力的，柔性抽油杆入卷筒前只承受拉力，故柔性抽油杆的受力情况大为好转，受力小、寿命长；而且不论提抽小车的提抽力多大都不会把提抽小车拉翻；同时提抽小车的移动与卷筒线槽螺旋距有严格的函数关系，可满足柔性抽油杆排列到卷筒上整齐有序不挤压，进一步防止因柔性抽油杆磨损而造成抽油效果和精度差的问题发生；抽力传感器是用来实时测量抽力大小以及控制、判断能否工作及液面深度。克服了现有提捞式抽油机存在抽油精度差、易污染环境、空间利用率差、安全隐患大且浪费较严重的问题。
卷筒上缠绕的柔性抽油杆的数量为两根，井口的数量为两个，且前后分布，井口上设置的井口密封器及对中机构的数量均为两个，卷筒下方设置有前端与其后端上下对应的前定滑轮，位于后侧的井口上方设置有后端与其轴心上下对应的后定滑轮，其中一根柔性抽油杆的一端与卷筒的左端部连接、另一端从卷筒前端竖向穿入与柔性抽油杆上下对应的井口，另一根柔性抽油杆的一端与卷筒的右端部连接、另一端从卷筒的后端依次经前定滑轮、后定滑轮竖向穿入与柔性抽油杆上下对应的井口。
该结构设计中，通过对柔性抽油杆数量及安装位置的改进，配合前后定滑轮的增设，实现了两个井口抽油时一个是上冲程，另一口是下冲程，双井双抽 相互平衡的同时，节能效果进一步得到提升。
一种石油开采用高精度提捞式抽油机，还包括控制器、位于提油小车行进方向一侧的限位开关，限位开关的输出端与控制器的输入端连接，控制器的输出端与减速制动电机的输入端连接。
作业时，当提油小车移动至接触限位开关时，柔性抽油杆到达指定深度，限位开关通过控制器来控制减速制动电机反转。
本发明结构设计合理可靠，实现了柔性抽油杆与井口密封器的时刻对准及柔性抽油杆与卷筒的排列整齐不挤压，保证了柔性抽油杆的精确抽油，杜绝了漏油污染环境现象的发生，而且占地面积小，安全性能得到提升，同时测量的抽力单一准确，节能效果显著，具有结构简单、加工方便且成本低的优点。

具体实施方式
一种石油开采用高精度提捞式抽油机，包括井口密封器1和固定在井口周围的抽油机架2，抽油机架2的上方设置有导轨架3，导轨架3与抽油机架2之间设置有抽力传感器4，且抽油机架2的四个角部固定有紧贴导轨架3四个角部的角钢状限位板5，导轨架3上设置有两根前后分布且左右放置的导轨6，导 轨6上设置有沿其左右移动的提油小车7，提油小车7上设置有卷筒8和减速制动电机9，减速制动电机9的输出轴与卷筒8的轴心相连，卷筒8上缠绕有一端与其端部连接、另一端经井口密封器1穿入井口的柔性抽油杆16；抽油机架2上设置有前后分布的对中机构和驱动机构；
对中机构包括对中底座10，对中底座10上固定有连接支架11，连接支架11上设置有两个左右分布且柱面紧贴的对中滚轮12，两对中滚轮12的柱面上开有位置对应的环状半圆槽13，两环状半圆槽13的紧贴处围成一个圆形的柔性抽油杆限位口，柔性抽油杆限位口、井口密封器1及卷筒8前端的任一螺旋槽上下位置对应；驱动机构包括固定在抽油机架2上的驱动支座14，驱动支座14上固定有上端部位于卷筒8螺旋槽内且与卷筒8螺旋槽配合的驱动杆15。
卷筒8上缠绕的柔性抽油杆16的数量为两根，井口的数量为两个，且前后分布，井口上设置的井口密封器1及对中机构的数量均为两个，卷筒8下方设置有前端与其后端上下对应的前定滑轮17，位于后侧的井口上方设置有后端与其轴心上下对应的后定滑轮18，其中一根柔性抽油杆16的一端与卷筒8的左端部连接、另一端从卷筒8前端竖向穿入与柔性抽油杆16上下对应的井口，另一根柔性抽油杆16的一端与卷筒8的右端部连接、另一端从卷筒8的后端依次经前定滑轮17、后定滑轮18竖向穿入与柔性抽油杆16上下对应的井口。
一种石油开采用高精度提捞式抽油机，还包括控制器、位于提油小车7行进方向一侧的限位开关，限位开关的输出端与控制器的输入端连接，控制器的输出端与减速制动电机9的输入端连接。
进行抽油作业时，首先通过减速制动电机9带动卷筒8旋转，进而将柔性抽油杆缠绕在卷筒8上开始提捞式抽油，与此同时，由于驱动杆15位于卷筒8的螺旋槽中，因此卷筒8的旋转驱动提抽小车7移动，当减速制动电机9带动 卷筒8旋转一圈时，提抽小车7移动卷筒8一个螺旋槽距离，保证柔性抽油杆16按螺旋槽整齐排列不挤压，当减速制动电机9带动卷筒8旋转到规定时间后抽油结束，柔性抽油杆16按卷筒8螺旋槽整齐排满完毕；当下放柔性抽油杆16时，减速制动电机9反向带动卷筒8旋转，这时驱动提抽小车7反向移动，当减速制动电机9带动卷筒8反向旋转一圈时，提抽小车7反向移动卷筒8一个螺旋槽距离，当减速制动电机9带动卷筒8反向旋转到规定时间后柔性抽油杆16下放结束；提捞式抽油机16完成一个提捞工作循环；角钢状限位板5保证导轨架3在安装抽力传感器4时的自由度。
具体实施过程中，驱动机构还可通过齿轮齿条传动、丝杠螺母传动等方式进行提油小车7的驱动。
