Abstract
The utility model relates to a control circuit used for a perforating gun or a perforating bullet constituted by a power supply (6), a control chip (5), a communication interface (4), and an igniting switch (2). The control circuit has functions of reporting the perforating gun information, monitoring the state, and controlling the igniting switch (2). The module can be used in a cascade manner, and one of the modules can be assigned to carry out the igniting task by the communication command, therefore the perforating guns or the perforating bullets can be controlled independently during the operation of selecting the perforating holes.
Description
Technical field
The present invention relates to the exploitation production field of petroleum gas, shale gas, coal bed gas etc., particularly a kind of control circuit that is used for perforating gun or perforating bullet.
Background technology
Typical perforating system is formed by connecting the appearance that detonates, cable, perforating gun and other supplementary instruments.During perforation, the appearance that detonates produces time break and is transferred to the down-hole, disposable all perforating bullets that detonate.Its advantage is when running into the more or several thin layers of heat-bodied oil gas-bearing formation when nearer, can carry out perforating job to a predetermined heat-bodied oil gas-bearing formation or several thin layer at every turn, and operation is simple, generally can not cause the mistake perforation.But along with the progress of oilfield exploitation pattern, the increase of thin difference layer, each the well section repeatedly requirement of perforation increases gradually.Especially the horizontal well perforation operation is complicated, if can once go into the well repeatedly perforation, will improve operating efficiency greatly, reduces cost, and improves safety, therefore, has been born and has published the perforating job pattern.
The main purpose of publishing perforation is to ignite one or more perforating bullets as requested, and other perforating bullets are unaffected.Can improve perforating job efficient like this, improve the perforation reliability, reduce cost.Its main points are go into the well a plurality of perforating guns of combination and perforating bullet at every turn, and can face each perforating gun and perforating bullet on ground and carry out independent control.
Summary of the invention
The objective of the invention is to solve the independent control problem of publishing each perforating gun in the perforating job or perforating bullet; For it provides a kind of highly reliable control circuit; Make perforating gun or perforating bullet accomplish ignition selectively according to terrestrial operation personnel's instruction, perforating gun or the perforating bullet of not receiving instruction then are ready.
Technical scheme of the present invention: control circuit is made up of power supply (6), control chip (5), communication interface (4) and ignition switch (2).Wherein, ignition switch (2) is connected with control chip (5), detonator (3), and communication interface (4) is connected with control chip (5).This control circuit is integrated in each perforating gun or the perforating bullet; Can the individual cascade of 1～N (N＜100) use; Passing pipe nipple with number is connected through cable; Consider the security reliability requirement of perforating job, its function comprises: report perforating gun or perforating bullet information, Stateful Inspection, ignition switch control.
After system powers on; Control circuit waits for that number passes pipe nipple it is accomplished address assignment; Obtain unique ID sign, whether information such as the model of the body of a gun, the amount of shooting, Kong Mi under the terrestrial system report then meet job requirements by operating personnel's perforation instrument of confirming to go into the well.
In the operation process, when instrument was transferred to the destination layer position, operating personnel sent order to the control circuit of suitable perforating gun or perforating bullet, and this perforating gun or perforating bullet are ready.At this moment, control circuit is reported the state of instrument ignition switch earthward, and after confirming through the operator, control chip (5) obtains firing command from communication interface (4), and closes ignition switch (2) is connected the detonator firing circuit.Other perforating gun or perforating bullet control circuit are closed the detonator firing circuit, avoid detonating.
The operator presses the button that detonates, and the perforation power supply produces the igniting electric pulse, and through perforating gun or the perforating bullet control circuit of cable transmission to appointment, detonating primer is accomplished the perforation process.After this perforation was accomplished, the operator operated winch, moves to other perforation layer position to instrument, carries out perforating job next time.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is circuit module serial connection sketch map;
Above-mentioned drawing reference numeral explanation: 1-cable, 2-ignition switch, 3-detonator, 4-communication interface, 5-control chip, 6-power supply, 10-perforating gun or perforating bullet 1,11-perforating gun or perforating bullet 2,12-perforating gun or perforating bullet N.
The specific embodiment
Shown in accompanying drawing 1, power supply among the present invention (6), communication interface (4), ignition switch (2) are connected with cable (1).Power supply (6) obtains input voltage from cable (1), and communication interface (4) passes pipe nipple through cable (1) and number and communicates by letter, and the blasting cap initiation signal that ground provides is also received ignition switch (2) input through cable (1).
It is control circuit work required voltage that power supply (6) will be imported high pressure converted.
Control chip (5) is through gathering voltage system, and monitoring ignition switch (2) state is uploaded to ground system through communication interface (4), realizes state-detection.And according to ground order closes ignition switch (2), detonator (3) detonated when the igniting electric pulse was arrived.
Shown in accompanying drawing 2; The control circuit module is integrated in perforating gun or the perforating bullet; Perforating gun or perforating bullet 1 (10), perforating gun or perforating bullet 2 (11), perforating gun or perforating bullet N (12) cascade are used, N＜100 wherein, and ground system uses communications command to specify certain module to implement igniting task.
Claims (2)
1. control circuit that is used for perforating gun or perforating bullet; Constitute by power supply (6), control chip (5), communication interface (4), ignition switch (2); It is characterized in that: ignition switch (2) is connected with control chip (5), detonator (3), and communication interface (4) is connected with control chip (5).
2. like said control circuit in the claim 1, it is characterized in that: control chip (5) obtains firing command, closes ignition switch (2) from communication interface (4).
