Abstract
The utility model relates to a data-transmitting-while-drilling device comprising an impulsator (1), an outer cylinder (2), a stress wave generator (3), a sensor cabin (4), a circuit cabin (5) and a positioning insert head (6). A groove is formed on the outer wall of the outer cylinder (2); a small cylindrical through-hole is communicated with the lower part of the groove; the stress wave generator (3) is arranged in the groove of the outer cylinder (2); a cable of the stress wave generator (3) passes through the small cylindrical through-hole and is connected with the sensor cabin (4); the sensor cabin (4) is provided with a cable connected with the circuit cabin (5); and the impulsator (1), the sensor cabin (4), the circuit cabin (5) and the positioning insert head (6) are connected sequentially in the center of the outer cylinder (2). The utility model can realize data transmitting in two modes: mud-pulse and stress wave, thereby solving the data transmitting problem when a mud system is in an idle state during the processes of round trip, well logging and the like.
Description
Technical field
The present invention relates to the field of oil drilling downhole tool, particularly a kind of with boring data sending apparatus in drilling process, belong to the downhole tool class.
Background technology
In recent years, along with improving constantly of drilling technology, real-time Transmission shaft bottom data have become the development trend of current drilling technology.In present shaft bottom data transmission technology, the main mud-pulse pressure signal that adopts is launched data, and make a trip, in the process such as well logging, because mud system remains static, cause the data in shaft bottom can't be real-time transmitted to ground, find following problem easily:
(1) in the process that makes a trip,, might cause serious accidents such as well kick, blowout because swabbing action makes bottom pressure produce fluctuation;
(2) in the well logging process, because mud system remains static for a long time, the borehole wall is soaked for a long time, might cause to collapse, and causes bottom hole pressure surge, has an accident.
Summary of the invention
It is a kind of with boring data sending apparatus that the utility model provides, and can realize mud-pulse and stress wave dual mode emission data, solve make a trip, in the process such as well logging because the data transmission problem of mud system when remaining static.
The technical solution adopted in the utility model is: be made up of pulse generator, urceolus, stress wave generator, transducer storehouse, circuit storehouse and location insert head, one groove is arranged on the outer drum outer wall, groove is communicated with a small cylindrical through hole, the stress wave generator places in the groove of urceolus, the cable of stress wave generator is worn the small cylindrical through hole and is connected with the transducer storehouse, the transducer storehouse has cable to be connected with the circuit storehouse, and pulse generator, transducer storehouse, circuit storehouse, location insert head connect successively and be positioned at the urceolus center.
The beneficial effects of the utility model are: this instrument can be realized mud-pulse and stress wave dual mode emission data, thereby guarantees under the mud inactive state monitor well truth of a matter certificate in real time, avoids the generation of complex accident.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
The utility model mainly is made up of pulse generator 1, urceolus 2, stress wave generator 3, transducer storehouse 4, circuit storehouse 5 and location insert head 6, on urceolus 2 outer walls groove is arranged, the groove bottom is communicated with a small cylindrical through hole, stress wave generator 3 places in the groove of urceolus 2, the cable of stress wave generator 3 is worn the small cylindrical through hole and is connected with transducer storehouse 4, transducer storehouse 4 has cable to be connected with circuit storehouse 5, and pulse generator 1, transducer storehouse 4, circuit storehouse 5, location insert head 6 connect successively and be positioned at urceolus 2 centers.
Its operation principle is: with boring data sending apparatus with the drilling tool G.I.H, after sensor acquisition arrives the data in shaft bottom, data are sent to the circuit storehouse, send to pulse generator and stress wave generator after data are handled in the circuit storehouse respectively, pulse generator transmits data to ground by changing mud-pulse pressure; When mud system remained static, the stress wave generator transmitted data to ground by drilling rod, guaranteed that the shaft bottom data can be transferred to ground in real time, was not subjected to the influence of mud fluctuation.
Claims (1)
1, a kind of with boring data sending apparatus, it is characterized in that: by pulse generator (1), urceolus (2), stress wave generator (3), transducer storehouse (4), circuit storehouse (5) and location insert head (6) are formed, on urceolus (2) outer wall groove is arranged, the groove bottom is communicated with a small cylindrical through hole, stress wave generator (3) places in the groove of urceolus (2), the cable of stress wave generator (3) is worn the small cylindrical through hole and is connected with transducer storehouse (4), transducer storehouse (4) has cable to be connected pulse generator (1) with circuit storehouse (5), transducer storehouse (4), circuit storehouse (5), location insert head (6) connects successively and is positioned at urceolus (2) center.
