A sucker rod male buckle and a sucker rod female buckle which are arranged at the upper end and the lower end of a setting rod are connected with a sucker rod male buckle of a choke holder respectively; an unthreaded hole and a female buckle which are arranged at the upper end and the lower end of a protecting cap respectively are connected with a male buckle at the upper end of a righting body; three plate springs are embedded in three pairs of friction blocks and installed in three slots of the righting body respectively; three spring shafts, three cam shafts, three cams and three shear pins are installed on three clamping nail plates and embedded in three slots of the righting body respectively; three tension springs are connected with the three spring shafts and the three cams respectively; and a female buckle and an unthreaded hole are arranged at the upper end and the lower end of a force transferring sleeve respectively, and the female buckle at the upper end is connected with a male buckle at the lower end of the righting body.
Description
One, technical field: the utility model relates to the go into the well special-purpose seat seal apparatus of grappling, sealing of a kind of petroleum and natural gas well restriction choke, especially blocks fourth seat envelope device.
Two, background technology: petroleum and natural gas well taps natural gas at present, in order to reduce the pressure rating of surface line and gas processing device import, preventing that gas well mouth from freezing freezes stifled and the mine water compound forms, certain depth optional position seat envelope restriction choke in the gas well flow string; Restriction choke is invested in the well testing truck steel wire for logging and realizes the anchor block envelope in the gas well oil pipe and whether can't predict anchor mechanism or sealing mechanism at the tubing coupling gap position.The gas well flow string is made up of 9 meters single oil pipes in the long left and right sides and oil pipe joint hoop, has the joint hoop slit of 25 millimeter between the single pin thread end face of oil pipe.Therefore the anchor mechanism of restriction choke, the possible grappling of sealing mechanism or sealing and joint hoop gap position so just influence restriction choke grappling and sealing effectiveness, and the success rate that drives a well is low.
Three, summary of the invention: the purpose of this utility model provides a kind of anchor mechanism or the sealing mechanism seat envelope and oil pipe joint hoop gap position that can avoid restriction choke, improve restriction choke and throw in the card fourth seat envelope device of the success rate of going into the well and drive a well, it is to throw in the production of restriction choke expenditure and pressure at oil exploitation natural gas well tubing string, the anchor mechanism of restriction choke, sealing mechanism might grapplings or are sealed in oil pipe joint hoop gap position, influence the grappling or the sealing effectiveness of restriction choke, grappling or sealing failure; Restriction choke is gone into the well throw in success rate low, cause and throw in the restriction choke operation of doing over again.Throw in the problem that restriction choke exists according to petroleum and natural gas well, the purpose of this utility model is such realization, it be by seat envelope bar, helmet, 3 leaf springs, 3 spring shafts, 3 camshafts, 3 cams, 3 cut off, power transmission cover, 3 tension springs, brake pad, centralizer body and 3 card fourth plates be formed by connecting, seat envelope bar upper end is connected with restriction choke sucker rod pin thread by sucker rod pin thread, lower end sucker rod box; Helmet upper end unthreaded hole, lower end box are connected with centralizer body upper end pin thread; 3 leaf springs are set in and are loaded in 3 pairs of brake pads in 3 grooves of centralizer body; 3 spring shafts, 3 camshafts, 3 cams, 3 cut off to be loaded on respectively on 3 card fourth plates and be set in 3 grooves of centralizer body; 3 tension springs are connected with 3 cams with 3 spring shafts; Box lower end, power transmission set upper side unthreaded hole, its upper end box is connected with centralizer body lower end pin thread.
Operating principle: card fourth seat envelope device is the corollary apparatus that petroleum and natural gas well is thrown in underground throttle device, prevents underground throttle device anchor mechanism, sealing mechanism, grappling, is sealed in the security precautions technology instrument of oil pipe joint hoop gap position.Card fourth seat envelope device is connected with restriction choke with well testing truck steel wire for logging input down-hole oil tube optional position when going into the well, and the cam mechanism of card fourth seat envelope device dwindles automatically in the process of going into the well; When card fourth seat envelope device and restriction choke arrive the gas well projected depth down, on carry card fourth seat envelope device and restriction choke, the cam of cam mechanism finds oil pipe joint hoop gap position automatically in spring action, and cam magnifies under the elastic force effect when finding oil pipe joint hoop gap position, is stuck on the joint hoop slit and realizes the location; Carry steel wire for logging in the continuation, restriction choke grappling, sealing realize giving up, cutting off of device of card fourth seat envelope cut off, cam return under the spring tension effect, the restriction choke grappling, be sealed in the below of joint hoop gap position, avoid the restriction choke grappling, be sealed in the vitta structure gap position, steel wire for logging plays card release fourth seat envelope device in ground, finishes restriction choke anchor block envelope.Improve restriction choke construction success rate.
The invention effect: the utility model is applicable to that the grappling of petroleum and natural gas well underground throttle device, sealing mechanism can avoid the security precautions technology instrument of oil pipe joint hoop position.Card fourth seat envelope device is the corollary apparatus that petroleum and natural gas well is thrown in underground throttle device, prevents underground throttle device anchor mechanism, sealing mechanism, grappling, is sealed in the security precautions technology instrument of oil pipe joint hoop gap position.Card fourth seat envelope device is connected with restriction choke with well testing truck steel wire for logging input down-hole oil tube optional position when going into the well, and the cam mechanism of card fourth seat envelope device dwindles automatically in the process of going into the well; When card fourth seat envelope device and restriction choke arrive the gas well projected depth down, on carry card fourth seat envelope device and restriction choke, the cam of card fourth seat envelope device cam mechanism finds oil pipe joint hoop gap position automatically in spring action, cam magnifies under the elastic force effect when finding oil pipe joint hoop gap position, is stuck on the joint hoop slit and realizes the location; Carry steel wire for logging in the continuation, restriction choke grappling, sealing, impact when realizing that restriction choke is given up, cutting off with the pin of giving up of card fourth seat envelope device cut off and cut off together, cam return under the spring tension effect, is sealed in the below of joint hoop gap position at the restriction choke grappling, avoids the restriction choke grappling, is sealed in the vitta structure gap position, steel wire for logging plays card release fourth seat envelope device in ground, finishes card fourth seat envelope restriction choke.Improve restriction choke construction success rate.
