Description

The safe docking facilities of underground operation tool
Technical field
The utility model belongs to the safe docking facilities of shaft mouth operation instrument, especially underground operation tool of petroleum industry, uses on operation wellhead, and the power tool of going into the well is docked safely with running string.
Background technology
At present in the underground work engineering, often need to change some short and small and weight is larger instruments of the use of going into the well at rig floor, as mill cone, roller reshaper, tricone bit, strong magnetic die, junk mill, lead stamp, normally working string is lifted from rig floor 1m left and right when going into the well, be generally two operating workers with portable and rotate lower well tool and dock with the tubing string screw thread, and then link closely.In lower well tool and process that the tubing string screw thread docks, because these lower well tools are heavier, particularly strong magnetic die, roller reshaper, be difficult to once dock successfully, if two operating worker mismatees also can cause lower well tool to fall, the personnel that perhaps cause injure.Operation field needs a kind of device that can realize that lower well tool docks with the safety of tubing string.
Summary of the invention
The purpose of this utility model is to make the safe docking facilities of underground operation tool, avoid occurring in lower well tool docking operation personnel's injury accident and to the damage of lower well tool, replace manpower to hold up lower well tool with this device, realize the function that lower well tool docks with the safety of tubing string, alleviate workman's labour intensity, guarantee the personal safety of operating worker.
The technical solution of the utility model is: the safe docking facilities of underground operation tool comprises seating nipple and support, and seating nipple is provided with chucking handle, rotary handle and fixing slip ring, and fixedly slip ring is welded on the cylindrical of seating nipple; Support comprises supporting slip ring and high pressure spring, and the high pressure spring is set in the vertical rod of supporting slip ring below, and seating nipple is placed in support, and making fixedly, slip ring is shelved on supporting slip ring.Lower well tool is put into seating nipple, replace manpower to hold up lower well tool with this device, realize that lower well tool docks with the safety of tubing string.
The beneficial effects of the utility model are: the utility model provides special tool with running string docking of well head for lower well tool, replace manpower to hold up lower well tool, can prevent that lower well tool from falling in docking operation, appearance personnel injury accident has realized that time well tool docks with the safety of tubing string.The utility model manufacturing is simple, reliable operation, has not only reduced workman's labour intensity, and has protected time well tool to avoid damage, has improved simultaneously the operating efficiency of well head docking, has obvious economic benefit.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done further detailed description.Referring to accompanying drawing, the safe docking facilities of underground operation tool comprises seating nipple 7 and support 8, and seating nipple 7 is provided with chucking handle 3, rotary handle 2 and fixing slip ring 4, and fixedly slip ring 4 is welded on the cylindrical of seating nipple 7; Support 8 comprises supporting slip ring 5 and high pressure spring 6, and high pressure spring 6 is set in the vertical rod of supporting slip ring 5 belows, and seating nipple 7 is placed in support 8, and making fixedly, slip ring 4 is shelved on supporting slip ring 5.Chucking handle 3 comprises fixedly block teeth 1 and connection handle, and fixedly block teeth 1 are the arc slips, are provided with slip insert on the intrados of arc slips; Connection handle is provided with the screwed connection in installing hole on screw thread and seating nipple 7; With a fixedly end welding of block teeth 1 and connection handle, be placed in seating nipple 7, the other end of connection handle is placed in the outside of seating nipple 7, is provided with spanner side or handler is installed.Chucking handle 3 is arranged on the top of seating nipple 7, is provided with at least three.Rotary handle 2 is welded on the cylindrical of seating nipple 7, is crisscross arranged with chucking handle 3.Support 8 also is provided with base 9 and spring spool, and vertical rod and spring spool all are welded on base 9, and high pressure spring 6 is set on outside vertical rod, and the bottom is placed in spring spool, and the top of vertical rod is provided with pin-and-hole, in-built lock pin.The cylindrical of supporting slip ring 5 is provided with mounting ring, this mounting ring is set on the pin-and-hole below at vertical rod top, and is spacing with lock pin.Vertical rod, spring spool and supporting high pressure spring 6 thereof are provided with three covers at least.
Tool barrel 7 of the present utility model is used for holding short and small heavy lower well tool, and fixedly block teeth 1 fixedly are placed on the interior lower well tool of tool barrel 7 by chucking handle 3, prevents that lower well tool self from rotating.Rotary handle 2 is used for turning tool cylinder 7 and realizes the make-up function, and fixedly slip ring 4 can make seating nipple 7 slide on supporting slip ring 5.
When using the safe docking facilities of this underground operation tool, this device is placed on rig floor tubing string below, the instrument that go into the well is placed in the tool barrel 7 of this device, according to the external diameter size of lower well tool, fix the interior lower well tool of tool barrel 7 by chucking handle 3.After fixing, transfer tubing string and lower well tool make-up, due to the effect of high pressure spring 6 on support 8, between lower well tool and tubing string, pretightning force is arranged all the time after make-up.After good button, with button on rotary handle 2, on to a certain extent, unclamp chucking handle 3 and make lower well tool throw off tool barrel 7, the upper lifting pipe post is completed make-up work.
