Abstract
A double-sealing disconnection-preventing heat-conducting oil pumping rod used for oil production in the oil well comprises a plurality of hollow pumping rods that are connected with each other through the abutting joint thread, a capping block that is arranged at the upper end of the upper section and the lower end of the lower section and a heat conducting working substance that is arranged inside the hollow cavity of the oil pumping rod; a square ring outer ring groove is arranged at the rear part of the abutting joint threat on the oil pumping rod, a split lathe dog that is matched with the upper and lower ring groove through the boss on both ends and is connected through a bolt, an interface sealing gluten layer is arranged on the external wall surface of the pumping rod between both ring grooves inside the lathe dog. Through the abutting joint thread, the utility model realizes the primary connection and sealing between two sections; through the match between the ring groove and the lathe dog as well as the interface sealing gluten layer that is arranged on the external wall surface, the utility model realizes the secondary connection and sealing between two sections so as to guarantee that the sectional connection has enough anti-torque capacity. The utility model has low allocation cost without performing film coating inside the cavity and applying the electronic starter, which is capable of meeting the requirement of the heat conducting working substance having lower boiling point and high working pressure and is reliable and stable to operate.
Description
Technical field
The utility model relates to the equipment of recover petroleum from oil well, is specifically related to a kind of double containment anticreep and leads warm sucker rod.
Background technology
At present, the sucker rod of leading temperature function that possesses that is used for recovering the oil in the oil field has two kinds, and a kind of is to lead warm coiled rod, and another is a geothermal crude oil production aid device.Lead warm coiled rod because sucker rod becomes monolithic, simple in structure, stable, but need purchase a whole set of sucker rod again when using, and be equipped with the special operation car, and one-time investment is huge, the cost height, and payoff period is long, influences it and applies.Geothermal crude oil production aid device constitutes hollow rod by some hollow oil pick-up tube serial connections, thereby can utilize existing hollow rod, help reducing use cost, but, it adopts butt joint screw thread or thread bush structure because connecting, the sealing reliability of junction is poor, particularly bear the ability of the moment of torsion that produces by the sucker rod motion, therefore problems such as refrigerant leakage, impurity infiltration often occur, even cause the generation of screw thread break-off accident.Simultaneously, because sealing effectiveness is poor, can't use the heat-conducting work medium of low boiling high workload pressure, can only rely on the inner chamber plated film and increase the problem that electronic starter remedies the start-up temperature deficiency, cause the cost of product to increase, the working stability performance reduces.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provide a kind of double containment anticreep to lead warm sucker rod, this sucker rod both can make full use of the existing conventional hollow rod, need not plated film and use electronic original part in the chamber again, can guarantee to lead warm sucker rod and have reliable and stable service behaviour.
The technical scheme that realizes above-mentioned purpose is: a kind of double containment anticreep is led warm sucker rod, it includes the more piece hollow rod that is connected through the butt joint screw thread, be arranged at joint sucker rod upper end and down joint sucker rod lower end shutoff and be installed in liquid phase-change heat-conducting work medium in the sucker rod hollow chamber, its on sucker rod in the annular outer groove in the side of being provided with, position at butt joint screw thread rear portion, be installed boss and annular groove up and down through the two ends merga pass screw that matches is connected and is provided with the separable type clip, and the sucker rod outside wall surface in the clip between two annular grooves is provided with the sealing joint glue-line.
The technical solution of the utility model also comprises: its outer groove is arranged to the inclined-plane by the side channel face of butt joint screw thread one side, and the inclined-plane is arranged to coincide accordingly in the side that its clip boss one side cooperates with it.
The utility model is threaded by butt joint, and the formation internode once connects and seals, and its hermetically-sealed construction adopts to add fluid sealant between conventional screw thread and dock end face gasket structure is set.Cooperation by side annular outer groove and clip and place the secondary of the realization of the sealing joint glue-line on sucker rod outside wall surface internode in the clip to be connected and seal, guarantee that simultaneously the internode connection has enough torque resistant abilities, lead warm sucker rod when making full use of existing hollow rod thereby make, need not to carry out plated film and use electronic starter in the chamber, can satisfy the requirement of the heat-conducting work medium that uses low boiling high workload pressure, and guarantee that sucker rod has stable and reliable service behaviour.
Description of drawings
Accompanying drawing is that this double containment anticreep is led warm sucker rod structural representation.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
Provide as accompanying drawing, this double containment anticreep lead warm sucker rod include the more piece hollow rod 1 that is threaded through butt joint, be arranged at joint sucker rod upper end and down joint sucker rod lower end shutoff 2 and be installed in liquid phase-change heat-conducting work medium 3 in the sucker rod hollow chamber, its on sucker rod 1 in the annular outer groove 4 in the side of being provided with, position at butt joint screw thread rear portion, be installed boss and annular groove 4 up and down through the two ends merga pass attachment screw 5 that matches is connected and is provided with separable type clip 6, and the sucker rod outside wall surface in the clip between two annular grooves 4 is provided with sealing joint glue-line 7.
The utility model is arranged to the inclined-plane with outer groove 4 by the side channel face of butt joint screw thread one side, the inclined-plane is arranged to coincide accordingly in the side that its clip 6 convex platforms one side cooperates with it, make the separable type clip in chucking, provide connection pressure, further improve the reliability of sucker rod internode bonding strength and sealing with respect to internode.
When the utility model was specifically implemented, its annular outer groove 4 in side that is arranged on the sucker rod can utilize original wrench side on the sucker rod.Sealant layer 7 can adopt rubber sleeve to substitute.
The utility model separable type clip also can adopt a side bearing pin connected mode.Its attachment screw also can be a connecting bolt.
Boiling point is lower than compound or its mixtures such as the above ketone of operate outside temperature 20 degree, ether, alcohol, aldehyde under the liquid phase-change heat-conducting work medium employing normal pressure that the utility model uses.
