Abstract
The utility model relates to a well mouth lifting device which is mainly used for solving the problems of testing well test or large work intensity of workers, easy injury and easy break of a testing device during the course of fishing tools under the well. The utility model is characterized in that a well mouth pulley bracket (2) is connected with a lifting rod (10) which penetrates a lifting rod slide sleeve (4). The outer part of the lifting rod slide sleeve (4) is connected with a spray prevention sleeve pipe (5), a fixing bolt (8), a well steel wire guide wheel and a lifting rod pull rope guide wheel (6). One end of the lifting rod pull rope (9) is connected with the lower end of the lifting rod (10), and the other end winds through the lifting rod pull rope guide wheel (6). The well steel wire (3) bypasses the well mouth pulley (1) and the well steel wire guide wheel which is parallel to the lifting rod pull rope guide wheel (6). The lifting device has the characteristics of simple structure, convenient operation and safety.
Description
Technical field:
The utility model relates to oilfield well testing test servicing unit, especially well head lifting device.
Background technology:
Field produces is in well testing test or down-hole fishing, need be at oil, the well lubricator is topmost got, following tester and down-hole fishing tool, lubricator stands on the well head production tree, its top is 4 meters of 3 ∽ far from ground, original getting, following tester or well head fishing tool method are: the well head operating personnel must stand on the footstool of lubricator, catch lubricator or live lubricator in case fall down on the other hand with the leg dish, with about about 1.5 meters of length, 45 millimeters of diameters, the tester of tens kilogram weights and downhole tool were lifted the crown of oneself, top by lubricator is got, following tester and downhole tool, this is got, the method of operating of following tester and downhole tool, not only labour intensity is big, and because operating personnel are that one hand is held up lubricator or carried out the personal safe protection with leg dish lubricator, very easily badly fall down, cause the impaired thing of injury to personnel or tester to take place from lubricator because of protecting.
The utility model content:
Big in order to solve in well testing test or the down-hole fishing tool process labor strength, be subject to injure the problem that tester is easily broken, the utility model provides a kind of well head lifting device, and this lifting device alleviates personnel labor intensity, has avoided the damage of personnel's tumble injury or tester.
The technical solution of the utility model is: this well head lifting device comprises lubricator, the well head pulley steel wire of going into the well, well head pulley bracket and blowout prevention pipe box, the well head pulley is connected on the well head pulley bracket, the well head pulley bracket is connected with the lifting arm that passes the lifting arm sliding sleeve, the lifting arm sliding sleeve is externally connected to the blowout prevention pipe box, dead bolt, go into the well steel wire directive wheel and lifting arm stay cord directive wheel, lifting arm stay cord one end connects the lifting arm lower end, the other end is walked around lifting arm stay cord directive wheel, and the steel wire of going into the well is walked around well head pulley and the go into the well steel wire directive wheel parallel with lifting arm stay cord directive wheel.
The utlity model has following beneficial effect: since adopt the lifting arm upper end connect well head pulley bracket lower end and can be in the lifting arm sliding sleeve free lifting, when needs are got, when following tester or downhole tool, pulling lifting arm stay cord, lifting arm is risen to predetermined height and lock by dead bolt, the well head pulley of lifting arm upper end together is raised to predetermined altitude together with the steel wire of going into the well simultaneously, the steel wire of going into the well connects tester or fishing tool, the locking back spurs the steel wire of going into the well, downhole probe or fishing tool sling put into lubricator or take out from lubricator, operating personnel utilize this device that tester and fishing tool are given rise to certain altitude on ground, put into and take out lubricator, not only alleviate labor intensity of operating staff, and avoided injury to personnel and the impaired situation of tester to take place; Open dead bolt, put down lifting arm and well head pulley, with dead bolt locking test sheave support, carry out next step test or fishing, do not need lifting get, down when tester or fishing tool, dead bolt is opened, made well head pulley half-twist, can get, descend tester or fishing tool easily.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-well head pulley among the figure, 2-well head pulley bracket, the 3-steel wire of going into the well, 4-lifting arm sliding sleeve, 5-blowout prevention pipe box, 6-lifting arm stay cord directive wheel, 7-lubricator, 8-dead bolt, 9-lifting arm stay cord, 10-lifting arm.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this well head lifting device comprises lubricator 7, well head pulley 1, the steel wire 3 of going into the well, well head pulley bracket 2 and blowout prevention pipe box 5, well head pulley 1 is connected on the well head pulley bracket 2, well head pulley bracket 2 is connected with the lifting arm 10 that passes lifting arm sliding sleeve 4, lifting arm sliding sleeve 4 is externally connected to blowout prevention pipe box 5, dead bolt 8, go into the well steel wire directive wheel and lifting arm stay cord directive wheel 6, lifting arm stay cord 9 one ends connect lifting arm 10 lower ends, the other end is walked around lifting arm stay cord directive wheel 6, and the steel wire 3 of going into the well is walked around well head pulley 1 and the go into the well steel wire directive wheel parallel with lifting arm stay cord directive wheel 6.
In the actual use, tester or fishing tool are connected with the steel wire 3 of going into the well, and the steel wire 3 of going into the well is walked around well head pulley 1 and the steel wire directive wheel and extend to ground of going into the well, it is motionless that the ground staff spurs the steel wire 3 of going into the well, lifting arm stay cord 9 one ends connect lifting arm 10 lower ends, the other end passes lifting arm stay cord directive wheel 6 and ground spurs lifting arm stay cord 9 by a people, make the well head pulley 1 of lifting arm 10 upper ends drive the steel wire 3 of going into the well and be raised to predetermined height, the well head operating personnel with dead bolt 8 half-twists after with lifting arm 10 locking, the personnel that ground spurs the steel wire 3 of going into the well spur steel wire, tester or fishing tool are sling, put into or take out lubricator 7, after the well head operating personnel decontrol the dead bolt half-twist, put down lifting arm 10 and by dead bolt 8 lockings, carry out downhole testing or fishing, this device has alleviated labor intensity of operating staff, has avoided injury to personnel and tester to be damaged, and has simple in structure, easy to operate, the characteristics of safety.
