System, address use coding mode；Pressure and magnetic orientation data in tension magnetic orientation are also encoded, by downhole instrument part
It is uploaded with agreement as defined in surface processing components；The signal decoding of surface processing components is using production ground in the maturation of application
Circuit coordinates DSP or CPLD to complete decoding；Whole process can realize that pressure, the magnetic orientation data of tension magnetic orientation are shown, release
It puts the addressing of device, addressing, confirm command procedure, then realize release；
3), perforation is hampered the magnetic orientation that detection release system is shown in using circuit switching control during entire go into the well
Data；To obtain depth data.
Preferably, equipped with special fishing head on the release.
Preferably, the perforation is hampered, detection release system passes through the expanded function of itself and the depth system of winch
System, ground tension, winch are shown, plotter is engaged togather.
Beneficial effects of the present invention are：Downhole instrument part can bear 140Mpa, 175 DEG C of high temperature and pressure；Floor treatment
Part shows pressure, magnetic orientation curve using chart, while having classification release function；Institute is functional all to concentrate on perforation chance
It realizes in resistance detection release system, and does not conflict with perforation control ground instrument；Instrument connects perforation during going into the well and is hampered
Detect release system, detection pressure and magnetic orientation situation；Once being hampered, operating personnel judges whether to enable according to data quantitative
Release device reaches release function in system, and this safer reality of method is reliable.
Description of the drawings
Fig. 1 is conventional perforation combination schematic diagram.
Fig. 2 is the perforation combination schematic diagram of the present invention.
Specific implementation mode
Detailed introduction is done to the present invention below in conjunction with attached drawing：As shown in Fig. 2, the present invention include end,
Weighted lever, perforating gun and classification perforation ground controller, wherein end, weighted lever, perforating gun connect together, the cable
Head is also connected with tension magnetic orientation, release, and the tension magnetic orientation, release are hampered by perforation detects the control of release system；Its
Be hampered detection release system, classification perforation ground controller of middle perforation is surface processing components, end, weighted lever, perforating gun,
Tension magnetic orientation, release are downhole instrument part, wherein perforating gun difference level-one perforation, two level perforation and N grades of perforations.Work as well
When lower instrument portion meets card, downhole instrument can quantify and measure the power being hampered, and decide whether to start according to the drag size being subject to
Release device；To eliminate because drawing the danger of cable bad or fracture caused by cable by force, cable is protected；It is disengaged
The lower part of instrument and release can carry out subsequent salvaging program, can freely salvage.These functions are integrated into one
System is internal, is a kind of new method, conventional has no this similar approach.Conventional perforation combination is as shown in Fig. 1, i.e. underground
Instrument portion is：End+magnetic orientation+weighted lever+perforating gun, perforating gun respectively penetrate by level-one perforation, two level perforation and N grades
Hole.Under this combination, perforation ground controller only obtains passive magnetic auditory localization cues and is used for school depth, once the basic nothing that is hampered
Method solves, and is directly discharged using external release at most, and without quantitative analysis.
Be hampered monitoring and solution of the downhole perforation of the present invention includes as follows：
1), this perforation is hampered detection release system using single-core cable transmission, from security consideration, to avoid and perforation control
Instrument conflict in ground processed, using the power supply mode of negative voltage；Downhole instrument part is hampered detection release system using half pair with perforation
The telemetry control system of work communication modes, address use coding mode；It opens pressure and magnetic orientation data is also encoded, by underground
Agreement as defined in instrument portion and ground system uploads；The signal decoding on ground is using production ground in the maturation electricity of application
Road coordinates DSP or CPLD to complete decoding；Whole process can realize that the tension of downhole instrument, magnetic orientation data are shown, release portion
Then the command procedures such as addressing, addressing, the confirmation divided realize release；
2), this perforation is hampered the magnetic orientation for detecting release system in the design using switching control；In practical applications, magnetic
It is located in the entire process of going into the well and has required display, and perforating job is extremely hazardous operation, so in underground away from well head hundred
Rice or so is not allow power-up operations (even negative electricity does not also allow)；It in this way must be during this section be gone into the well using passive
Magnetic orientation obtains depth data, this perforation detection release system that is hampered is avoid the occurrence of this situation, and inside is cut using circuit
It brings and solves the problems, such as this；
3), perforation control ground instrument using single-core cable transmission, therefore in implementation process must both sides be independent of each other；It penetrates
The positive voltage of hole ground controller, which must be isolated to be hampered into entrance aperture, detects release system, while must will also be penetrated in instrument lower end
Hole be hampered detection release system voltage isolation in case under be transmitted to perforating gun；In instrument internal using a variety of isolation, switch means
Address, data, perforation order etc. are efficiently separated；
4), the structure division of downhole instrument part carries out Aseismic Design and security and Reliability Design, in tension magnetic orientator
Device is popped one's head in and electronic circuitry part uses anti-seismic structure；It is strengthened simultaneously on the basis of the Aseismic Design of release safe and reliable
Property design；Especially the material of key position and tension resistance are all tested accordingly.
Equipped with special fishing head on the release, the plenty of time is saved for the salvaging in later stage, can effectively be carried
High oil field production operation efficiency.
This perforation is hampered detection release system there are expanded function, for example, consider with the depth system of winch, ground tension,
The linkings such as winch shows, plotter, this is customized according to the actual demand of client.
The downhole perforation of the present invention is hampered, and the institute in monitoring and solution is functional all to be concentrated on the perforation detection that is hampered and releases
It realizes in place system, and does not conflict with perforation control ground instrument.Instrument connects perforation during go into the well and is hampered detection release
System, detection pressure and magnetic orientation situation.Once being hampered, operating personnel judges whether to release in enabling system according to data quantitative
Device is put to reach release function, this safer reality of method is reliable.
It is understood that it will be understood by those skilled in the art that being subject to technical scheme of the present invention and inventive concept
The protection domain of appended claims of the invention should all be belonged to replacement or change.
