Description
Technical field
The utility model relates to a kind of in oil exploration drilling engineering, for the continuous wave slurry pulse generator of wireless drilling measurer.
Background technology
In drilling engineering, spudder author and geomatics engineer need to be understood the working condition of downhole tool at any time, the form of borehole track and stratum and downhole environment parameter.Owing to being subject to the radial dimension of well (elongated hole) and the restriction of well site working condition, make down-hole become and be not easy to the realization of the information real-time Transmission on ground.At present, once occurred or the transmission means used has electrical conduction mode (hard wiring system), electromagnetic wave mode, sound wave mode and drilling fluid pulse mode.Because hard traverse method, electromagnetic wave mode and the sound wave mode information transmission system exist a series of problems that are difficult to overcome in actual applications, or be subject to the strict restriction of ambient conditions, make the information transmission system of these several modes not obtain aborning generally application.And only have drilling fluid pulse mode more simple in structure than alternate manner, and do not need special drilling rod, can not increase complex situations because of having wire in well, by on-the-spot drilling engineer, extensively adopted, be current the most practical the most reliable down-hole information transmission means.
In drilling process, need continuous circulation cleaner for high-pressure drilling fluid, drilling fluid promotes drill bit downwards along drilling rod, then returns to ground through the annular space between drilling rod and well, carries out landwaste, makes drill bit can contact borehole bottom and continues to creep into.Now, drilling fluid has formed a continuous media of crossing ground from shaft bottom, and this continuous media can be used as the desirable signal transmission passage from shaft bottom to ground.
Drilling fluid pulse information transmission mode is actually by pressure differential transmission in drilling liquid flow and realizes transfer of data.In drilling fluid pulse measurement-while-drilling system (MWD, LWD) or well geosteering system, rotary steerable drilling system, its downhole instrument is generally all provided with sensor and the corresponding downhole data harvester of measuring well geometric parameter, formation parameter and engineering parameter, processor of single chip computer and control system, and have a mud pulse generator that is used for producing drilling liquid pressure pulse signal.
According to the method for multiple generation drilling liquid pressure poor (pressure pulse), mud pulse generator also has multiple.At present, most popular mud pulse generator mainly contains following several in the world:
1) negative pulse generator is to make the raw negative pressure differential (negative pressure pulse) of drilling fluid liquid miscarriage by a shunt valve is installed between and drill set annular space around inner in drill set; There are some researches show, negative pulse easily damages the borehole wall, and downhole probe structure and complicated operation, therefore seldom use.
2) positive pulse generator, by the valve of a restriction drilling fluid liquid stream is installed in the somewhere of drilling fluid liquid stream, controls the resistance to drilling fluid liquid stream loop by valve, thereby produces drilling fluid liquid stream positive pressure pulse.Positive pulse generator is conventional at present a kind of mud pulse generator.
3) continuous wave impulse generator, its transmitter is the valve of a rotation, the disk that this valve flows rectangular grooved hole by a pair of and drilling fluid liquid forms.One fixing, and another rotates with certain speed, produces a regular continuous pressure ripple, while sending data, by changing the parameters such as phase place, frequency of compression wave, realizes.
As shown in Figure 1, instrument is placed in drill collar 1 to common continuous wave slurry pulsator principle, by centralizer 5, is fixed on drill collar 1 central authorities, and stator 2, stepper motor 4, inserting tube 6 are relative with centralizer 5 fixing, and rotor 3 is driven by stepper motor 4.The combination of stator 2, rotor 3 is commonly referred to as shutoff valve, on stator 2 and rotor 3, all has flowing hole, and when flowing hole overlaps, the local resistance of shutoff valve place is minimum; When flowing hole staggers, the local resistance of shutoff valve place is by the corresponding increase of the angle staggering.When drilling fluid 7 flows, the well head pressure that the variation of shutoff valve place local resistance is finally reflected to drilling fluid changes.Ground installation measuring well mouth pressure, after filtering with decoding, must arrive the data that send down-hole.
Patent (mud pulse generator 200910259625.9), (a kind of rotary underground slurry pulse generator 201120059734.9), (continuous wave slurry pulse generator 201110452486.9) all relate to common continuous wave slurry pulsator, rotor is all direct or indirect to be connected with output shaft motor, and its driving force mainly comes from high power motor.Yet, use motor can consume a large amount of electric energy as main driver part, tens watts of few persons, the upper hectowatt of many persons, this is very large load concerning the downhole instrument of truth of a matter km in depth, has affected greatly its continuous firing ability.
