Abstract
An eccentric water distributor without throwing and dragging belongs to a kind of downhole tool for an oilfield water injection well. The eccentric water distributor is composed of a strong magnet (1), a shearing pin bolt (2), a piston (3), a piston cover (4), a magnet pocket (5), and a packer main body (6); the strong magnet (1) is arranged on one end of the packer main body (6), the shearing pin bolt (2) is connected with the piston (3) and the piston cover (4) respectively in an across manner, and the magnet pocket (5) is arranged on one side of the packer main body (6); ground equipment (test carriage), ground instruments (well logging instrument) and throwing/dragging tools are saved; production efficiency is improved by saving the throwing and dragging process; water injection operation success rate is improved, and water injection may be performed without failure basically. The utility model has characteristics of simplifying operation processes, improving production efficiency, reducing production cost, alleviating labor strength, and preventing the packer from throwing and dragging.
Description
Technical field:
The utility model relates to the used downhole tool of water injection well in oil fields, is specifically related to a kind of casting and dragging free eccentric injection mandrel.
Background technology:
The used eccentric injection mandrel of water injection well in oil fields was 665-2 and 665-3 type in the past, must be furnished with special-purpose Ground Operation equipment (for example test carriage etc.) and special tool (throw in catcher) and weighted lever etc.Its operation procedure is:
One, use blanking plug that ground installation and throw in catcher will have dead mouth from the underground to the down-hole, use cementing truck water filling pressure testing then, check whether water injection string has seepage,
Two, the blanking plug that uses ground installation and throw in catcher will have dead mouth takes out from the down-hole, and the blanking plug that will have cock carries out the water filling operation then from the underground to the down-hole again.This method complex procedures, the activity duration is long, needs large-scale ground equipment and special tool, and can not guarantee very high success rate, usually is forced to carry out maintenance activity because throw in catcher occurs faults such as weighted lever, throw in catcher, steel wire fall in the down-hole when delivering.
The utility model content:
The purpose of this utility model provides a kind of casting and dragging free eccentric injection mandrel, and it can simplify flow chart, enhances productivity, and reduces production costs, and alleviates labor strength, has the characteristics of casting and dragging free blanking plug, can reach 100% by one-time success rate.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is made up of strong magnet 1, shear pin 2, piston 3, piston bush 4, magnet pocket 5, blanking plug main body 6; Strong magnet 1 is arranged on an end of blanking plug main body 6, and cross-under is on piston 3 and piston bush 4 respectively for shear pin 2, and magnet pocket 5 is arranged on a side of blanking plug main body 6.
The utility model adopts and install hydraulic piston in advance on eccentric injection mandrel, along with down-hole string one removes the precalculated position, down-hole, uses cementing truck water filling pressure testing then, checks the sealing situation of water injection string.After the sealing of determining water injection string is all right, continue to suppress, the shear pin on the piston is cut off, and piston is gone out, and beats in the magnet pocket of the other end, is adsorbed by spatial magnet, and current just can inject the stratum by piston bush like this.
The utlity model has following beneficial effect: remove ground installation (test carriage) ground instrument (well logging instrument) and pulling and running tool etc. from; Remove the pulling flow chart from, enhance productivity; Improve the water filling job success ratio, can accomplish water filling failure-free operation substantially.Simplify flow chart, enhance productivity, reduce production costs, alleviate labor strength, have the characteristics of casting and dragging free blanking plug, can reach 100% by one-time success rate.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an assembly structure schematic diagram of the present utility model.
The specific embodiment:
Referring to Fig. 1, this specific embodiment by the following technical solutions: it is made up of strong magnet 1, shear pin 2, piston 3, piston bush 4, magnet pocket 5, blanking plug main body 6; Strong magnet 1 is arranged on an end of blanking plug main body 6, and cross-under is on piston 3 and piston bush 4 respectively for shear pin 2, and magnet pocket 5 is arranged on a side of blanking plug main body 6.
Described strong magnet 1 has that intensity is done, high temperature resistant, corrosion resistant characteristics.
The utility model adopts and install hydraulic piston in advance on eccentric injection mandrel, along with down-hole string one removes the precalculated position, down-hole, uses cementing truck water filling pressure testing then, checks the sealing situation of water injection string.After the sealing of determining water injection string is all right, continue to suppress, the shear pin on the piston is cut off, and piston is gone out, and beats in the magnet pocket of the other end, is adsorbed by spatial magnet, and current just can inject the stratum by piston bush like this.
The utlity model has following beneficial effect: remove ground installation (test carriage) ground instrument (well logging instrument) and pulling and running tool etc. from; Remove the pulling flow chart from, enhance productivity; Improve the water filling job success ratio, substantially can accomplish water filling failure-free operation. Simplify flow chart, enhance productivity, reduce production costs, alleviate labor strength, have the characteristics of casting and dragging free blanking plug, can reach 100% by one-time success rate.
