Abstract
The utility model discloses a multistage packer fishing tool for a water injection well. The upper part of a main body (2) is provided with a rope socket connector (1), and the lower end wall of the main body (2) is provided with a guide nib (7); the middle part of the main body (2) is provided with 2 to 4 slots in a segmentation manner, and each slot is provided with a branch arm (4); and a cam (3) is arranged on the side surface of the upper end of each slot. As a plurality of groups of independent fishing structures comprising the branch arms and strong magnets are integrated on the same main body, the multistage packer fishing tool can be used for fishing a plurality of underground equipment simultaneously in one operation of descending the well, so that the packer fishing tool can save the time of wellhead operation, is energy-saving and safe, and is high in efficiency and low in cost. The multistage packer fishing tool is simple in structure and convenient to operate, and can improve the effects of field operation greatly.
Description
Technical field
The utility model relates to instrument or tool technique or the device in the water injection well for oil operation, the especially multistage fishing tool of water injection well blanking plug.
Background technology
In the prior art, single support arm fishing tool is used in water injection well work usually, is used for salvaging the equipment such as tester that take out the down-hole from eccentric water injection, uses single support arm throw in catcher, and the work Instrumental is gone into the well often.On-the-spot fishing Instrumental must be salvaged one by one, therefore goes into the well often; Such as, take three layers of water injection well of two-stage as example, use single support arm fishing tool need to implement 6 operations of going into the well or promote, just can finish input work, longevity of service, efficient is low; Along with the increase of water filling layer, putting number of times certainly will also can increase, and wastes time and energy, and the improvement technology of Effective Raise operating efficiency discloses less.
Summary of the invention
Goal of the invention of the present utility model provides the multistage fishing tool of a kind of water injection well blanking plug, this device can be salvaged special tool as eccentric water injection, is mainly used in salvaging blanking plug, by changing the water nozzle in the blanking plug, regulate the water injection rate on stratum, finally play the effect that improves recovery ratio.
The purpose of this utility model will realize by following technical measures: there is the rope socket joint main body upper end, and the guiding nib is arranged on the main body lower end wall, and segmentation is opened 2 to 4 grooves and support arm is installed respectively on the main body middle part, every section groove upper side cam is installed.
Advantage of the present utility model and effect: adopt the integrated independent structures of salvaging that comprise support arm and strong magnetic of organizing on same main body more, once descending the salvaging of finishing simultaneously many underground equipments in the well operations, save the shaft mouth operation time, energy-saving safety, efficient is high, cost is low, and it is simple in structure and easy to operate, has greatly improved the field operation effect.
Description of drawings
Fig. 1 is structural representation of the present utility model
Reference numeral comprises: rope socket joint 1, main body 2, cam 3, support arm 4, strong magnetic 5, blanking plug 6, guiding nib 7.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
There is rope socket joint 1 main body 2 upper ends, and guiding nib 7 is arranged on main body 2 lower end walls, and segmentation is opened 2 to 4 grooves and support arm 4 is installed respectively on main body 2 middle parts, every section groove upper side cam 3 is installed.
Support arm 4 roots are hinged on the main body 2.
The groove inner bottom part is installed strong magnetic 5.
Support arm 4 lower ends have clamping joint to connect blanking plug 6 afterbodys.
In the utility model, as shown in Figure 1, segmentation is opened on main body 2 middle parts, 3 grooves and 3 support arms 4 of corresponding installation, take three layers of water injection well of two-stage as example, need in normal circumstances lower three times downhole tools just can finish the input work of blanking plug, blanking plug all can be pulled out and the fishing tool with three support arms in the use present embodiment is disposable, as long as next is all over the input work that just can finish blanking plug, reduced the working time, improved operating efficiency, same principle, for water injection well more multi-layered more than 3 or 4 layers, advantage is more obvious.
The utility model is when work, take the water injection well of three layers of two-stages as example, at first transfer fishing tool to below three layers of this well, on carry fisher, during this instrument process seating nipple, because seating nipple is that internal diameter is 46mm, the diameter of bigger fisher, three support arms 4 all open by the rotation of cam, then continue to put continuous lower fisher, lowermost support arm 4 can be sitting on the three level work cylinders, on carry fisher and extract blanking plug 6, at this moment blanking plug 6 is sucked in support arms 4 grooves by strong magnetic 5 with support arm 4, this provides the space just for top support arm 4, top support arm 4 can be worked, finish successively salvage.
