Background technology
The application of extended reach well and horizontal well technology improves well yield and oil gas field recovery ratio greatly, has reduced the oil and gas development cost, but a key character---high frictional resistance, high moment of torsion cause horizontal section length limited when creeping into.Air drilling can significantly shorten well construction period, the protection oil-gas Layer.Air drilling is combined the gas horizontal well drilling, the extended reach well technology that produce with horizontal well, extended reach well technology be that non-conventional gas and oil is hidden, the powerful measure of marginal Reservoir Development, but this technology can meet with higher frictional resistance and moment of torsion in drilling process, suppressed the extensive use of this technology.
Improving gas bores the extension ability of extended reach well, horizontal well and effectively reduces the key that the frictional resistance moment of torsion is this combination technology success.Therefore design has been invented a kind of for gas brill extended reach well or horizontal well, the antifriction instrument with the function of axially creeping.Conventional antifriction instrument is divided into rotation and non-rotating two large classes; mainly comprise non-rotating drill pipe protector, drilling rod bearing short joint, DSTR pipe nipple, low drilling rod moment of torsion and various underground vibrating device, tractor, boost motor etc.; it is to reduce the effective contact size of drilling rod in pivoting friction by this type of instrument that resistance mechanism falls in anti-attrition, reduces the frictional resistance at effective contact point place.The present invention is based on the mechanics of materials, engineering mechanics and aerodynamics, by rational design, not only reduce the effective size of drilling rod in pivoting friction, reduce the frictional resistance at effective contact point place, while is in conjunction with the principle drafting tool axial advancement of tractor, initiatively creep, effectively improve the extension ability of drill string in well.
Summary of the invention
Purpose of the present invention: a kind of instrument that improves drill string down-hole extension ability, reduces frictional resistance that has is provided, proposes especially the antifriction instrument with the function of axially creeping that a kind of gas brill extended reach well or horizontal well are used.
In order to achieve the above object, the present invention solves the technical scheme that this technical problem adopts: a kind of antifriction instrument with the function of axially creeping, mainly by top connection, upper cone, outer sleeve, the worm screw mandrel, lower cone, lower contact, worm gear, worm gear drive shaft, support, friction overdrive clutch, the crawling wheel positioning lining, crawling wheel, left helical gear, right helical gear, the compositions such as crawling wheel power transmission shaft and cover plate, by the worm screw mandrel, worm gear, friction overdrive clutch, left helical gear, the combination gearing of right helical gear and crawling wheel makes this instrument have driving shaft to the function of creeping in drilling process.
Worm screw mandrel and worm gear engagement, the torque energy when drill string is crept into partly converts tool spindle to the power of creeping.
The worm screw mandrel rotates and drives the worm gear rotation, drives friction overdrive clutch by worm gear drive shaft and rotates, and friction overdrive clutch to left helical gear and right helical gear, travels forward transmission of power finally by crossing crawling wheel power transmission shaft drive crawling wheel.
Further provide the annexation of torque transmission mechanism, worm screw mandrel and worm gear engagement, worm gear and friction overdrive clutch are fixed in the two ends of worm gear drive shaft, worm gear drive shaft is installed on two fixed supports, two supports are fixed in the outer sleeve, by worm screw mandrel, worm gear and worm gear drive shaft moment of torsion is delivered to friction overdrive clutch, forms torque transmission mechanism;
Further provide the annexation of climbing mechanism, friction overdrive clutch fixing on the worm gear drive shaft meshes with left helical gear and right helical gear simultaneously; Left helical gear and crawling wheel are fixed in the two ends of a crawling wheel power transmission shaft, and right helical gear and another crawling wheel are fixed in the two ends of another root crawling wheel power transmission shaft; Left helical gear, right helical gear, two crawling wheel power transmission shafts and two crawling wheels all are arranged in the crawling wheel positioning lining, and the crawling wheel positioning lining is placed in the hole of being located on the outer sleeve and is screwed, and on the crawling wheel positioning lining cover plate is set; Friction overdrive clutch drives simultaneously two crawling wheels when rotating and travels forward, and forms climbing mechanism, and the ability of creeping is provided.
Friction overdrive clutch is one-way rotation mechanism, when on when carrying drill string, crawling wheel counter-rotating but can not transmit torque to worm gear mandrel and drill string.
A preferred scheme is, worm screw mandrel and three worm gears engagements of pressing the 120 ° of distributions in phase angle, form three groups of torque transmission mechanisms, arrange at outer sleeve that to have the phase angle be three identical holes of 120 °, one group of crawling wheel positioning lining is installed in each hole, arranging like this can guarantee that crawling wheel contacts with the borehole wall in arbitrarily circumferential orientation, traction drill string axial advancement.
The crawling wheel positioning lining is put into the hole and be screwed, left helical gear and a crawling wheel are fixed in crawling wheel power transmission shaft two ends, right helical gear and another crawling wheel are fixed in another root crawling wheel power transmission shaft two ends, then respectively two groups of crawling wheel power transmission shafts are positioned in the positioning lining, allow left helical gear and right helical gear mesh with friction overdrive clutch simultaneously, add upper cover plate, crawling wheel positioning lining and cover plate are screwed.Friction overdrive clutch and worm gear are fixed in the worm gear drive shaft two ends simultaneously, at last the worm screw mandrel are rotated in round buss, allow worm gear and worm engaging, so that the power of creeping to be provided.When friction overdrive clutch rotated, moment of torsion was delivered to the crawling wheel power transmission shaft by left helical gear and right helical gear, drove at last crawling wheel and rotated forward, formed climbing mechanism, played antifriction, and driving shaft is to creeping the effect of traction drill string axial advancement.
