Abstract

The utility model provides a tool which is used for salvaging for an inclinometer thrown in a well in well drilling construction. The fishing tool is composed of a threading joint (1), a salvaging barrel (3), a salvaging joint (8), etc., wherein, a hook (6) which can rotate around a fixed axle (7) is arranged in the salvaging barrel, and the hook (6) can be opened by itself to clamp the salvaging joint (8) connected with the inclinometer after the salvaging barrel (3) enters the well and salvage the inclinometer which completes the test. The utility model has the advantages of simple structure and high efficiency and is suitable for field application.

Description

Fishing tool for inclinometer in well
The utility model relates to a kind of in wellbore construction, the instrument that the inclinometer of G.I.H is salvaged during to the well bore deviational survey.
In wellbore construction, for guaranteeing wellbore quality, whenever creeping into 50-100 rice just must deviational survey.The two kinds of methods of surveying are surveyed and are thrown in hanging of using at present.Hang to survey and exactly inclinometer is connected with winch cable, along with winch rotates the inclinometer G.I.H, because the frictional force between wire rope and the drilling rod, decrease speed is slow, inclinometer be subjected to again itself with the restriction of clock, not down to the shaft bottom, instrument is just started working often, has influenced the accuracy of test; Throw surveying is that inclinometer is directly dropped in the drilling rod, and inclinometer is equivalent to freely falling body, and decrease speed is fast, and test accuracy rate height still, must all trip out drilling tool from the down-hole after finishing deviational survey, and den bohrkopf abbauen could take out inclinometer.For a bite deep-well, in whole drilling process, need deviational survey tens times, if every deviational survey once all should pull out of hole, just take a lot of work, time-consuming, influence bit speed.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of down-hole inclinometer fisher that do not pull out of hole of designing, making.
This fisher is to be connected to form from top to bottom by wire rope handling joint (1), weighted lever (2), fishing socket (3), fishing joint (8), it is characterized in that having in the fishing socket can be around the grab (6) of fixed axis (7) rotation, the top of grab (6) is supported by spring (5), and the lower surface is the inclined-plane.When fishing joint (8) with after grab (6) inclined-plane contacts, its conical surface can strut grab (6) and enter fishing socket (3), grab under the effect of spring (5) (6) resets it can not be deviate from.
Accompanying drawing 1 is a structural profile schematic diagram of the present utility model.(1) is the wire rope handling joint among the figure, and (2) are weighted lever, and (3) are fishing socket, and (4) are pressure caps, and (5) are springs, and (6) are grabs, and (7) are fixed axis, and (8) are fishing joint, and (9) are inclinometers.
Now the 1 pair of the utility model structure and working condition are further described in conjunction with the accompanying drawings: when drilling well needs deviational survey, inclinometer (9) (part of only drawing among Fig. 1) linked to each other and tighten the spiral shell button with fishing joint (8) drop in the drilling rod, process is with above-mentioned throwing survey method.After to be tested the finishing, the hole that wire rope on the winch is penetrated wire rope handling joint (1) top is also fixing, again wire rope handling joint (1), weighted lever (2), fishing socket (3) are connected as one from top to bottom and G.I.H, coming downwards to fishing joint (8) with the winch rotation locates, this moment is under the pressure of top weighted lever (2), the conical surface of the lower bevel of grab (6) and fishing joint (8) interacts and moves, the bottom of grab (6) is opened and is that rotate in the axle center with fixed axis (7), grab (6) top holddown spring (5).It is descending that fishing socket (3) continues, and fishing joint (8) just all enters fishing socket, this moment under the effect of spring grab (6) the bottom in receipts block fishing joint (8) shoulder and make it can not deviate from (state as shown in Figure 1).The backward rotation winch, on carry steel cable, inclinometer (9) is promptly by being salvaged out.The effect of pressure cap (4) is that fishing joint (8) is separated with fishing socket, when pressing cap (4) from outer buttons, receives in the top of grab (6), and the bottom can be opened, and fishing joint (8) is promptly deviate from.
The utility model has following advantage compared to existing technology: be applicable to and throw the tilt measurement of surveying, avoided hanging when surveying, slow because of decrease speed, when inclinometer arrives the shaft bottom not yet down, owing to limiting to start working, clock own affects the problem of deviational survey point accuracy, avoided again simultaneously surveying when not having this fisher because throwing, the drawback that every survey once all will pull out of hole can be saved a large amount of manpower and materials, and is safe and reliable, simple for production, the fishing success ratio height.

Claims (1)

1, a kind of down-hole inclinometer fisher that is used for wellbore construction, it is made up of wire rope handling joint (1), weighted lever (2), fishing socket (3), fishing joint (8), it is characterized in that having in the fishing socket can be around the grab (6) of fixed axis (7) rotation, its top is supported by spring (5), and the lower surface is the inclined-plane.
