Abstract
The utility model provides a novel taking out or lowering down tool for a protective sleeve of an oil gas well mouth, composed of an anchor body, a shim plate, a pressing plate, a spring and an anchor fluke. The pressing plates with different specifications are changed and installed on the taking off tool which does not need selecting the position, so the protective sleeve with different specifications can be taken off. The both ends of the anchor body are a drill rod father buckle and a drill rod mother buckle which are suitable for taking off the protective sleeve freely under the situation of empty well and the situation with a drilling tool. Therefore, the utility model satisfies the well-drilling production requirement with safety and high efficiency.
Description
When the utility model relates to a kind of oil gas well drilling, the new tool that the wellhead protecting cover takes out and is lowered to.It mainly is made up of anchor body (1), backing plate (2), pressing plate (3), spring (4) and anchor fluke (5).
At present, the protective sleeve taking-up instrument of China's use is that the lamp button takes out instrument.Be two ears of on the joint that an external diameter and protective sleeve internal diameter match, burn-oning, the opening of two lamp buttons of upper end symmetry processing of protective sleeve, during taking-up, two ears that protective sleeve is taken out instrument align the opening of protective sleeve, and take out back, card jail.But this taking-up instrument only plays the taking-up effect, and the difficulty of processing of protective sleeve is big, and intensity is low; in using at the scene, taking-up instrument and protective sleeve align difficulty, and the protective sleeve lamp is buckled fragile; can only take well head like this apart and take out protective sleeve, usually influence carrying out smoothly of drilling well work.
The purpose of this utility model is to provide a kind of has drilling tool or empty well not to need direct bearing in well; need not tear well head open and just can take out and be lowered to the new tool of protective sleeve quickly and safely, and thoroughly changed the deficiency that protective sleeve exists on processing and intensity.It is low that this takes off the instrument cost, easy to use, changes the pressing plate of different size, with regard to the protective sleeve of applicable different size, satisfied safety, drilling well production requirement efficiently.
The purpose of this utility model can reach by following measure: this protective sleeve takes off instrument and mainly is made up of anchor body, backing plate, pressing plate, spring and anchor fluke.The spring of packing in the hole on each face of square of anchor body middle part, the small end of anchor fluke inserts in this hole, and an end on band inclined-plane inserts in the hole of pressing plate, and two holes align, and with screw anchor body and pressing plate are connected as one.When need taking out protective sleeve, the instrument that will take off slowly is lowered to well head, and anchor fluke stretches under spring action in the inner groove of protective sleeve automatically with protective sleeve card jail, proposes protective sleeve then and promptly finishes the taking-up operation.
The purpose of this utility model can also reach by following measure: load onto backing plate, pressing plate respectively on each face of square of anchor body; with screw it is connected as one; again the screw thread on protective sleeve screw thread and the pressing plate outer is screwed; protective sleeve can be sent to the well head precalculated position; instrument is taken off in proposition, just finishes protective sleeve and transfers operation.
The drawing of accompanying drawing is described as follows:
Fig. 1: protective sleeve takes out the tool construction schematic diagram
Fig. 2; Protective sleeve is lowered to the tool construction schematic diagram
Provide example of the present utility model below in conjunction with accompanying drawing:
The spring (4) of packing in the square hole on each face of square of anchor body (1) middle part, the small end of anchor fluke (5) inserts in this square hole, and an end on band inclined-plane inserts in the hole of pressing plate (3), connects anchor body (1) and pressing plate (3) with screw (6).When needs take out the protective sleeve of different size; pressing plate (3) with the corresponding specification of protective sleeve only need change the outfit; upper end with anchor body (1) is connected with drilling rod again; slowly be lowered to the well head precalculated position taking off instrument then; anchor fluke (5) stretches under the effect of spring (4) in the inner groove of protective sleeve automatically with protective sleeve card jail, proposes protective sleeve and promptly finishes the taking-up operation.
As run into when carrying out drillng operation and need take out protective sleeve, the lower end screw thread that takes off moveable anchor body (1) can be connected with drilling tool, can be lowered to, take out protective sleeve.
In drillng operation; when need are lowered to well head with protective sleeve; then pressing plate (3) and the backing plate (2) loaded onto respectively on each face of square of anchor body (1) with the corresponding specification of protective sleeve; connect with screw (6) and to be one; again the screw thread on protective sleeve screw thread and pressing plate (3) outer is screwed; protective sleeve can be sent to well head precalculated position back-off, back-off proposes to take off instrument, just finishes protective sleeve and transfers operation.
The model machine of this utility model is on probation through two drilling teams in my unit, has reached purpose of design fully, and cost of production is low, and execute-in-place is easy, and is safe and reliable.
