Abstract
The utility model relates to an underground high pressure jetting drilling tool which uses a turbine as the dynamic force in the well drilling engineering of petroleum. The utility model is composed of a short joint 2 of the turbine, a multi-stage centrifugal pump 5, a drill bit 6, a jetting nozzle 7, etc., wherein, the short joint 2 of the turbine, the multi-stage centrifugal pump 5 and the drill bit 6 are connected in sequence, and the jetting nozzle 7 which is penetrated through the drill bit 6 is communicated with the multi-stage centrifugal pump 5. The structure of a main bearing is simplified, and the service life of the turbine is improved. An underground accelerating box which works in a fully sealing way does not contact with well liquid and does not have rubber elements, and the underground accelerating box has the ability of adapting the underground environment temperature of 200 DEG C. The utility model is especially suitable for the level of devices of the existing well drilling teams in China.
Description
It is that the down-hole high pressure of power sprays drilling tool with the turbine that the utility model relates to a kind of in the petroleum drilling engineering.
Jet drilling was used widely the seventies, significantly improve bit speed and reduce drilling cost, but be subjected to the restriction of borehole pump and high pressure line, jet drilling is only to having very good effect than soft formation, intensification along with drilling depth, the stratum hardening, and water-horse power loses very greatly because of drilling rod is oversize, hydraulic drilling is greatly affected.Foreign oil industry at present drops into huge fund for improving bit speed aspect super-pressure drilling well research, develop two-tube well system, can improve the effect of 2～5 times of drilling speeds, can't promote the use of in China's industry but its cost is too high.
The purpose of this utility model be to provide a kind of can be in most evil bad underground work, to drilling fluid only is common purification requirement, require lower to the ground mud pump system, and have very long down-hole application life, what really realize jet drilling at big degree of depth well is that the down-hole high pressure of power sprays drilling tool with the turbine.
The utility model is achieved in that by turbine pipe nipple 2, gearbox 3, solid-liquid separator 4, centrifugal multistage pump multiple centrifugal pump 5, drill bit 6, injection nozzle 7, the big hydrophthalmia 8 of drill bit to be formed, turbine pipe nipple 2, gearbox 3, solid-liquid separator 4, centrifugal multistage pump multiple centrifugal pump 5, drill bit 6 connect successively, the big hydrophthalmia 8 of drill bit is arranged on the drill bit 6, and injection nozzle 7 runs through drill bit 6 and communicates with centrifugal multistage pump multiple centrifugal pump 5.
Advantage of the present utility model is: adopt the ripe turbodrill driving gearbox that is used as power, base bearing is not bearing the pressure of the drill of drill bit in the turbodrill, has therefore simplified the base bearing structure greatly, and has greatly improved the turbine working life.Centrifugal multistage pump multiple centrifugal pump is the centrifugal pump part of oil field electric submersible pump commonly used, the technology maturation reliable operation.The core component down-hole gearbox of this drilling tool is totally-enclosed work, does not contact with well liquid and does not have rubber element, and the ability that adapts to 200 ℃ of down-hole ambient temperature is arranged.Because of turbine and centrifugal pump higher to the adaptive capacity of bottom hole temperature (BHT) and drilling fluid, so be fit to on-the-spot complex working condition; The drill bit of using this drilling tool uses the heavy caliber hydrophthalmia, as long as guarantee ground mud pump delivery, can guarantee the injection capacity of this drilling tool down-hole, therefore greatly reduce the ground system requirement, this device is fit to the equipment of domestic existing drilling crew very much, is convenient to promote.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described further:
Form by turbine pipe nipple 2, gearbox 3, solid-liquid separator 4, centrifugal multistage pump multiple centrifugal pump 5, drill bit 6, injection nozzle 7, the big hydrophthalmia 8 of drill bit, turbine pipe nipple 2, gearbox 3, solid-liquid separator 4, centrifugal multistage pump multiple centrifugal pump 5, drill bit 6 connect successively, the big hydrophthalmia 8 of drill bit is arranged on the drill bit 6, and injection nozzle 7 runs through drill bit 6 and communicates with centrifugal multistage pump multiple centrifugal pump 5.
Use existing turbine pipe nipple 2, drive down-hole gearbox 3, through gearbox 3 speedup rear drive centrifugal multistage pump multiple centrifugal pumps 5, centrifugal multistage pump multiple centrifugal pump 5 intakes are established solid-liquid separator 4 and are sucked drilling fluid, through centrifugal pump 5 is multistage be pressurized to 30～50Mpa after by 7 ejections of drill bit 6 injection nozzles.
