Description
Technical field
This utility model relates to the classification perforating job carrying out cable transmission during oil field produces, especially a kind of for cable
The classification perforation center tap of transmission.
Background technology
Along with continually developing of oil field, a lot of main forces thick oil pay yield is successively decreased year by year, in order to keep stable production of crude oil, large quantities of relatively
Thin poor oil reservoir puts into exploitation in succession.Develop this type of oil reservoir, when carrying out perforation construction, owing to individual well oil reservoir is thin, layer position is many, layer
Between span big, use conventional cable transmission mode to carry out perforation, go into the well every time and can only penetrate open an interval, to penetrate out individual well
Multiple intervals, it is necessary to repeatedly remove perforating gun.This mode perforation workload is excessive, its perforating job time length, efficiency is low,
Labor strength is big.
Utility model content
In order to solve above-mentioned technical problem present in background technology, this utility model provides a kind of for cable transmission
Classification perforation center tap, this joint be classification perforating gun string connect intermediate member, its cavity built with ignite and control dress
Putting, solid and reliable, resistance to compression is high temperature resistant, and instrument lower end is equipped with fluid control pressure switch module, except playing the work being shot through momentary breaks
With, moreover it is possible to play the effect upwards sealed.
Technical solution of the present utility model is: a kind of classification perforation center tap for cable transmission, its feature exists
In: include top connection 1, hold line storehouse 2, sealing drum 3, lower contact 4 and fluid control pressure switch module 5；Upper end, described appearance line storehouse 2 with
Top connection 1 threaded one end connects, and holds middle part, line storehouse 2 side and windows, open with sealing drum 3 or airtight side is windowed, holds line
Lower end, storehouse 2 arranges female thread and external screw thread, is used for installing fluid control pressure switch module 5, fluid control pressure switch module 5 and lower contact
4 connect.Hold lower end, line storehouse 2 to threaded with lower contact 4.
Also including sealing cock 6, described sealing cock 6 is arranged on the side tapping of lower contact 4.
What top connection 1, lower contact 4 and appearance line storehouse 2 were connected is external screw thread.
The utility model has the advantages that:
1) this utility model includes upper and lower joint and holds line storehouse, top connection and lower contact external screw thread respectively with perforating gun spiral shell
Stricture of vagina connects, and screw thread type can coordinate processing according to perforating gun thread type, it is simple to this center tap is extended to different oil fields difference rule
Lattice perforating job uses；
2) this utility model center tap, holding line storehouse is side openings structure, and this structure is convenient for repair and maintenance, connects
After completing perforating gun string at different levels, if going wrong, being not required to dismantle perforating gun at different levels step by step, directly opening sealing drum and just can detect line
Road problem, while reducing labor strength, improves perforating job efficiency.
3) this utility model center tap, fluid control pressure switch module can ensure up and down on the premise of transmission power-on and power-off signal
The sealing of level perforating gun, subordinate's rifle can also mechanically cut off electrically connecting of the superior and the subordinate's perforating gun after igniting；Fluid control pressure is opened
Close module and can carry out integral replacing after terminating as an accessory, each perforation, after perforation, change all consumable accessorys, maintenance
Reuse after maintenance.

Detailed description of the invention
As it is shown in figure 1, the classification perforation center tap for cable transmission provided by the utility model, including top connection 1,
Hold line storehouse 2, sealing drum 3, lower contact 4, fluid control pressure switch module 5, seal cock 6.Top connection 1 external screw thread is according to perforating gun
Button-type customization processing, there is seal groove at two ends, ensure the sealing inside and outside perforating gun after installing sealing ring；Hold line storehouse 2 left end
Screw into top connection 1 right-hand member, at the outer shaft shoulder；If top connection central hole size can expand to and hold line storehouse inner chamber size
Size is identical, can be by top connection 1 with to hold line storehouse 2-in-1 and be a part；Hold the middle outer openings in line storehouse 2, place from opening part
Ignite and control device；There is seal groove in opening both sides, with sealing drum 3, opening is sealed after dress sealing ring.
Fluid control pressure switch module 5 male end has seal groove, it is ensured that the sealing of the superior and the subordinate's perforating gun, is connected to hold line
Storehouse 2 right-hand member endoporus；Lower contact external screw thread and subordinate perforating gun are connected, and its outer wall side perforate is used for connecting fluid control pressure
Cable between switch module 5 and subordinate's perforating gun, last wiring completes to use sealing cock 6 to block.
Apply this utility model below to install and use when the classification perforation of cable transmission and illustrate:
Classification perforation center tap for cable transmission is connected between adjacent two-stage perforating gun, is attaching it to perforation
Before rifle, the preparation before connecting perforating gun can be completed in indoor, appropriate high temperature lubricating at all sealing rings, will be smeared
Silicone grease, first threadeds top connection 1 right-hand member with appearance line storehouse 2 left end and is integrated, allow sealing drum 3 be inserted in appearance line storehouse 2 from right-hand member
Behind middle part, then pilot-controlled switch module 5 male end cable calm line storehouse 2 right-hand member centre bore is penetrated to middle opening standby
With, make external screw thread be torqued-up to hold line storehouse 2 right-hand member；Then pilot-controlled switch module 5 right-hand member cable is passed from lower contact 4 centre bore,
Lower contact 4 left end female thread is made to connect as one with holding line storehouse 2 right-hand member external screw thread.
During onsite application, by being first connected with higher level's rifle, then the order installation being connected with subordinate rifle；It is first turned on sealing drum 3,
Primacord that higher level's rifle is pulled out and run through cable to be pulled to hold line storehouse 2 middle chamber from top connection 1 centre bore standby, will ignite and
Control device and put into appearance line storehouse 2 cavity, after connecting all cables on request, place precession sealing drum after all devices and cable
Make appearance line storehouse 2 opening airtight；Subordinate's rifle runs through line penetrate from lower contact 4 centre bore, pull out from side perforate, make lower contact 4
Connect as one with subordinate rifle；Subordinate's rifle is run through line and fluid control pressure switch module to run through line complete from side tapping wiring
Cheng Hou, fills in lower contact 4, blocks perforate with sealing cock 6；
According to above method, multi-stage perforator rifle is installed according to actual needs, finally utilizes cable transmission mode to connect
Classification perforating gun string transfer to sleeve pipe oil reservoir position, after school is deep, first ground ignition control ignites next stage perforating bullet, well
Lower liquid enters in lower contact with perforating gun holes, makes fluid control pressure switch module 5 action, disconnects and electrically connecting with upper level, with
Time guarantee that highly pressurised liquid will not enter upper level and not ignite in body of perforating gun；On carry perforating gun string to next oil reservoir position, repeat
Said process, carries out the perforating job of this mouthful of well successively.
