Description

一种井架移动快速定位装置
技术领域
本发明属于石油设备领域,具体涉及一种井架移动快速定位装置。
背景技术
在传统的油田修井作业中,修井机的井口对中是保证修井作业的关键步骤,目前做法是修井机到达井场,通过司机目测井口位置开动车辆前后、左右移动来实现修井机井口对中,此种方式需要不断调整车辆位置,操作困难、精度差、效率低,经常会耗费半天时间进行车辆位置调整,目前还没有一种很好的技术解决此类问题。
发明内容
本发明所要解决的技术问题是:提供一种井架快速对正井口的机构,提高修井机井口对中作业效率。
本发明的技术解决方案是:一种井架移动快速定位装置,其特征是:井架支撑座可以沿底盘车的横向和纵向移动,井架支撑座上集成了防喷器组,防喷器组可以升降移动并绕其中心旋转,井架的起升缸支撑于井架支撑座上,随支撑座一起移动,与井架相对位置保持不变。
本发明当井架对中井口后,起升缸将支撑起井架至作业状态,然后调整防喷器组高度,使防喷器组安装到井口四通上,实现修井作业前的对中井口工作。
本发明具体地说是根据井口位置,在拖车到达预定位置附近,不必进行精细的车辆移位进行井口对正,而是通过调整车辆上的井架前后左右的位置进行井口对正,实现快速精确定位。
本发明的技术效果是:井架支撑座结构设计合理、使用方便可靠、精确定位、自动化控制等优点,能够实现井架与井口位置的快速对正,同时井口防喷器组固定于快速定位装置上,运输时伸缩液缸收起,防喷器组一起随车运输,不必每次作业进行吊运安装,提高修井作业准备工作的效率,降低操作人员的劳动强度。

具体实施方式
井架移动快速定位装置主要包括空间三个方向的移动,井架前后移动、井架左右移动、井口设备上下移动,本发明主要工作过程如下:
井架前后移动:当修井机开至井口位置后,通过操作井架前后移动油缸(13),使井架前后移动支架(10)沿着井架前后移动导轨(12)前后移动,其中井架起升油缸座板(15)与井架前后移动支架(10)连为一体,井架起升油缸(16)定位于井架起升油缸座板(15)上并随之一起前后移动,确保井架起升油缸(16)与伸缩井架(1)相对位置不变。其中支撑架(9)与井架前后移动支架(10)连为一体,双闸板防喷器(5)与井架前后移动支架(10)一起前后移动,通过测量双闸板防喷器(5)位置确定井架前后位置是否到位。
井架左右移动:当井架前后位置调整到位后,通过操作井架左右移动油缸(14),使井架前后移动支架(10)、井架前后移动导轨(12)、井架前后移动油缸(13)、井架起升油缸(16)、双闸板防喷器(5)一起沿着井架左右移动导轨(11)左右移动,通过测量双闸板防喷器(5)位置确定井架左右位置是否到位。
井口设备上下移动:当伸缩井架(1)移动到位后,通过调整井架支撑座升降油缸(8)使井架支撑座(7)支撑到地面,根据井口四通(6)的位置高低不同,通过防喷器升降装置油缸(2)调整防喷器升降支架(3)高度,使双闸板防喷器(5)高度适宜井口四通(6)高度。其中双闸板防喷器(5)固定在防喷器支撑架(4)上,防喷器支撑架(4)可以绕防喷器升降支架(3)旋转,用来适应不同井口四通(6)的法兰孔连接位置。
综上所述,本发明当底盘车移动到井口附近时,不必通过移动车辆进行精准定位,只需要粗略定住位置,然后通过井架支撑座上的液缸调整井架前后或左右的位置实现井口对中,大大提高工作效率。
