Description

Two electricity pump cable passes through pkr

Technical field

The utility model belongs to oil exploration and development fields, specifically, it relates to a kind of oil production underground operation tool, passes through pkr in particular to a kind of two electricity pump cable.

Background technology

In oil production process, in order to prevent gas blowout accident, usually using a kind of oil cover annular space insulation tool on electric submersible pumping flow string, its effect is the shutoff oil cover annular space when blowout, prevents well liquid and other liquid from overlapping annular space by oil and gushes out pit shaft. Oil cover annular space insulation tool must have to be produced passage, exhaust-duct, cable gallery and passes reserved passage in order to tiny pipeline overlaps annular space at oil.

Chinese utility model patent CN101845943A provides a kind of universal packer for through cable, and this structure only excessively singly organizes cable, and whole pkr is eccentric, is not easy to separate envelope. Chinese utility model patent CN102758597A provides a kind of split Hexamermis spp cable-passing packer, this construction increases test and medicine feeding hole passage, but cable aperture passes through cable can only be hole three core, is unfavorable for sealing and withstand voltage.

Practical novel content

For overcoming above-mentioned the deficiencies in the prior art, the utility model provides a kind of two electricity pump cable and passes through pkr, is not easy to separate the not high problem of envelope, poor sealing, resistance to pressure to solve cable-passing packer.

For achieving the above object, the utility model adopts following proposal:

Two electricity pump cable passes through pkr, comprising: major joint; Wherein: described major joint bottom is ladder structure, main operation pore, venting valve opening, first group of cable entry port, pre-opened hole, control string holes, the 2nd group of cable entry port it is provided with; Described first group of cable entry port and the 2nd group of cable entry port pass through respectively for two electricity pump six roots of sensation cable.

Compared with prior art, the utility model has the following advantages:

1, whole Distribution of Institutions is symmetrical, is convenient to separate envelope, direct upper lifting pipe post shear pin, it is not necessary to other operations;

2, each string holes size is substantially identical, and central distribution is on same circle, can make mandrel internal diameter maximumization, is convenient to connect the big oil pipe of internal diameter;

3, multiple aperture passes through body, passes through respectively for two electricity pump six roots of sensation cable, and good airproof performance, resistance to pressure is strong, and top pressure can reach 70MPa.

Embodiment

As shown in Figure 1 and Figure 2, two electricity pump cable passes through pkr, comprising: major joint 1, piston 3, interior slip cap 4, snap ring 5, spring 6, interior slip block 7, slipping block cover 8, packing element 9, upper cone 11, slips 13, lower cone 15, slips cover 16, mandrel 17, hydraulic hold-down 20; Wherein:

Described major joint 1 bottom is ladder structure, is provided with main operation pore 21, venting valve opening 22, first group of cable entry port 23, pre-opened hole 24, control string holes 25, the 2nd group of cable entry port 26; Described first group of cable entry port 23 and the 2nd group of cable entry port 26 pass through respectively for two electricity pump six roots of sensation cable, and single root good sealing effect, withstand voltage properties height, can reach 70MPa.

Described first group of cable entry port 23, pre-opened hole 24, control string holes 25, the 2nd group of cable entry port 26, pore size is identical, and central distribution is on same circle.

Described main operation pore 21, venting valve opening 22, first group of cable entry port 23, pre-opened hole 24, control string holes 25, the 2nd group of cable entry port 26, one-piece construction is distributed symmetrically, and is convenient to separate envelope, direct upper lifting pipe post shear pin, it is not necessary to other operations.

Described major joint 1 circumferential surface is provided with circular step hole, and hydraulic hold-down 20 is put in the step hole in major joint 1.

Major joint 1 time end is connected with connected pipes 18 threaded upper ends.

Described mandrel 17 is enclosed within connected pipes 18, and upper end is threaded with major joint 1, and piston 3 is nested on mandrel 17, snap ring 5, spring 6, interior slip block 7, is nested between mandrel 17 and piston 3 annular space successively.
