Abstract
The utility model discloses a mechanical well-depth localizer used for oil industries, and the mechanical well-depth localizer is applicable to various wells with lower packers. The utility model makes the both ends of an elastic locating body connected with an upper end plug and a lower end plug, and nested on a locating short joint. Vehicles and equipment for measuring the depth of a well do not need to be used by the utility model, and the cost of production is obviously reduced. The mechanical well-depth localizer has timely locating and convenient operation. The utility model is only needed to be downwardly placed in the well following a pipe post, and encounter clipping display can be spotted put from a weight-indicating meter on a ground surface. After the pipe post is lifted to obtain a definite load after the locating is finished, the localizer can be invalid, no longer has a locating function, and can not influence back any work.
Description
Technical field
The utility model belongs to the downhole tool of petroleum industry, and mechanical type well depth locator particularly is applicable to the well of all kinds of lower packets.
Technical background
Along with going deep into of oil field development, need the well of lower packet seal more and more, and require the packing position more and more accurate, the interlayer of packing is also more and more thinner, this just need accurately locate, and present location mainly is by measuring oil pipe, and finishes the location work of packer deeply with the cable school.With cable school dark is that to employ equipment many, the expense height, and the 2nd, untimely, take a lot of work and mistake.Need to develop a kind of accurate location that the dark device in cable school is realized packer of not having for this reason.
Summary of the invention
Task of the present utility model provides mechanical type well depth locator, overcomes above-mentioned defective of the prior art, makes the work of measuring well depth simple, timely, reduces production costs and working strength of workers.
The present technique solution can reach above-mentioned purpose: mechanical type well depth locator, two ends connection upper plug head and lower end cap with the elasticity positioning body are set on the orientation spool.
The utility model compared with prior art has following significant effect: 1, need not to employ special-purpose dark vehicle of well logging and equipment, obviously reduced cost of production; 2, the location is timely, and is easy to operate.Only need with the utility model with tubing string in well, upper lifting pipe post when needing the location, this instrument then can be met card at the casing coupling place, can find out that meeting card shows from the weight indicator of ground.Use the same method and to find out all casing couplings that need the location.3, after the upper lifting pipe post reached certain load after finished the location, locator will lose efficacy, and no longer play the role of positioning, and also not influence later any operation.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: bottom short circuit 1, tubing coupling 2, orientation spool 3, lower end cap 4, positioning sleeve 5, shear pin 6, elasticity positioning body 7, upper plug head 8, joint 9.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description: referring to accompanying drawing, mechanical type well depth locator is made up of elasticity positioning body 7, orientation spool 3, upper plug head 8, lower end cap 4 and shear pin 6, the two ends of elasticity positioning body 7 are connected upper plug head 8 and lower end cap 4, be set on the orientation spool 3.Elasticity positioning body 7 is made up of reed, reed positioning sleeve, positioning sleeve 5 and shear pin 6, has 2 vertical slots on the positioning sleeve 5 at least, more than 2 also can, interior dress reed, the reed positioning sleeve is inserted in the reed lower end, shear pin 6 is fixed on the reed positioning sleeve on the positioning sleeve 5.Orientation spool 3 two ends are connected with tubing coupling 2 with joint 9, the tubing coupling 2 following pipe nipples 1 that connect.During on-the-spot the use, search the casing coupling position at the place, need location of well inner sleeve at first as requested, then this instrument be connected on the tubing string that needs the location, measured tubing string, with tubing string in well.Upper lifting pipe post when needing the location, elasticity positioning body 7 can be met card at the casing coupling place, meets card as can be seen from the ground weight indicator and shows, the good tubing string side of mark is gone into, and has write down the degree of depth, continues running string, to needing position location upper lifting pipe post, use the same method to find out all casing couplings that need the location.After the upper lifting pipe post reached certain load after finished the location, shear pin 6 of the present utility model will be cut off, and continued the upper lifting pipe post, and the reed of elasticity positioning body 7 will be by in the income positioning sleeve 5, and this instrument will lose efficacy, and no longer play the role of positioning, and also not influence later any operation.
