Abstract
The utility model is disclosed is the wear-resistant cable threeway of a kind of heating sucker rod pumpingh well, can be widely used in heating sucker rod pumpingh well, is particularly useful for thick oil thermal extraction.The threeway of this cable comprises bend pipe and body, and bend pipe is communicated with body, and cable fixed mechanism is housed in body, and cable fixed mechanism is provided with cable through hole, and hollow polished rod joint is suspended in suspension joint, and the bottom of body is connected with suspension joint.Heating cable is fixed in hollow polished rod joint, and heating cable can be with the heating sucker rod synchronous reciprocating motion oil pumping that is connected to hollow polished rod joint bottom.Heating cable and electrical heating sucker rod inwall do not have relative motion, and the electrical heating hollow rod inwall heating cable that can not wear and tear in the application life that can improve heating cable, reduces that oil well stops production and maintenance, and the management difficulty of oil well is little.When heating cable is carried in operation, heating cable can be because mill resistance is large and unexpected stressed being pulled off, and heating cable can continue to use, and has significantly reduced cost of production.
Description
Technical field
The utility model relates to the wellhead equipment of petroleum industry heating sucker rod pumpingh well, and the particularly wear-resistant cable threeway of a kind of heating sucker rod pumpingh well, can be widely used in heating sucker rod pumpingh well, is particularly useful for thick oil thermal extraction.
Background technology
The hollow polished rod upper end of heating sucker rod pumpingh well connects the device that can obliquely wear cable, is called cable threeway.Existing cable threeway is exactly the assembly of a straight tube and a bend pipe, cable can be from bend pipe G.I.H, the inner parts without any attached cable, protection cable.Hollow polished rod is when moving back and forth along with oil pumper, the electrical heating hollow rod of hollow stem polished rod bottom is called for short heating sucker rod, can extend and shorten, heating cable and electrical heating sucker rod inwall have relative motion, the electrical heating sucker rod inwall heating cable that can wear and tear, causes heating cable often to damage, and needs often to change maintenance, affect oil well production, increase oil well management difficulty.After the rising of the temperature of heating cable, also can extend in addition, meeting is crooked in heating sucker rod, and when heating cable is carried in operation, heating cable can not be used because of mill resistance and unexpected stressed being pulled off, and causes huge economic loss.
Summary of the invention
The purpose of this utility model is to provide the wear-resistant cable threeway of a kind of heating sucker rod pumpingh well, avoids heating cable to be worn in electrical heating hollow rod, improves the application life of heating cable, reduces oil well and stops production and overhaul, and increases economic efficiency.
Technical solution of the present utility model is: the wear-resistant cable threeway of a kind of heating sucker rod pumpingh well comprises bend pipe 2 and body, bend pipe is communicated with body, cable fixed mechanism is housed in body, cable fixed mechanism is provided with cable through hole, hollow polished rod joint is suspended in suspension joint, and the bottom of body is connected with suspension joint.
The beneficial effects of the utility model are: the connecting thread of fastening end cap and cylinder base, can its internal diameter be dwindled extruded cable stationary magazine creel, thereby can clamp heating cable, the weight of heating cable is transferred on cable stationary magazine creel, the weight of heating cable pulls down cable stationary magazine creel, make the cone of cable stationary magazine creel bottom be subject to the extruding of hollow polished rod joint upper taper inner chamber, cable stationary magazine creel inwall more closely clamps heating cable, thereby heating cable is fixed in hollow polished rod joint, heating cable can be with the heating sucker rod synchronous reciprocating motion oil pumping that is connected to hollow polished rod joint bottom.Heating cable and electrical heating sucker rod inwall do not have relative motion, and the electrical heating hollow rod inwall heating cable that can not wear and tear in the application life that can improve heating cable, reduces that oil well stops production and maintenance, and the management difficulty of oil well is little.
byupper end in heating cable is held, and makes heating cable be suspension status, in stretched vertically state, can be in electrical heating hollow rod crooked under Gravitative Loads.When heating cable is carried in operation, heating cable can be because mill resistance is large and unexpected stressed being pulled off, and heating cable can continue to use, and has significantly reduced cost of production, has significant economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing in detail the utility model is described in detail, and unrestricted protection domain of the present utility model.Referring to Fig. 1, the wear-resistant cable threeway of a kind of heating sucker rod pumpingh well comprises bend pipe 2 and body 3, bend pipe 2 is communicated with body 3, cable fixed mechanism is housed in body 3, cable fixed mechanism is provided with cable through hole, hollow polished rod joint 5 is suspended in suspension joint 4, and the bottom of body 3 is connected with suspension joint 4.Cable fixed mechanism comprises end cap 6, cable stationary magazine creel 7 and cylinder base 8, and cable stationary magazine creel 7 is seated in cylinder base 8, and the top of cylinder base 8 is connected with end cap 6.Cable stationary magazine creel 7 outward appearances are cones that two is little, middle part is wide, are provided with cable through hole
, be centre bore, this cable is corresponding with the centre bore of bend pipe 2 through hole; Cable stationary magazine creel 7 middle part cylindricals are provided with shoulder seat on the inner circle shoulder of cylinder base 8, and the material of cable stationary magazine creel 7 is high density polyene material, also can adopt nylon material.Cable stationary magazine creel 7 be flap to zoarium, as two lobes, three lobes or more lobes, be more conducive to extruding and attached cable.The inner chamber of end cap 6 is that conical internal cavity coordinates with the top cylindrical shell of cable stationary magazine creel 7, cylindrical is provided with external screw thread and is connected with the internal thread of cylinder base 8.Hollow polished rod joint 5 upper end cylindricals be provided be affiliated to shoulder seat on the inner circle shoulder of suspension joint 4, its top inner chamber is that conical internal cavity coordinates with the bottom cylindrical shell of cable stationary magazine creel 7, the bottom inner circle of hollow polished rod joint 5 is provided with hollow stem polished rod screw thread 9.The top of body 3 is threaded with lifting arm 1, and lifting arm 1 is solid hopkinson bar, and body of rod middle part is thin, two ends are provided with bar head.Certainly this lifting arm 1 also can with body 3 integral manufacturings.
During oil pumping, square clamp is stuck on the body of rod of lifting arm 1, makes heating cable under polished rod eye, can protect cable not damaged.Heating cable enters in the electrical heating hollow rod of bottom from bend pipe 2, cable stationary magazine creel 7, hollow polished rod joint 5.The connecting thread of fastening end cap 6 and cylinder base 8, can dwindle its internal diameter by extruded cable stationary magazine creel 7, and cable stationary magazine creel 7 plays fixedly heating cable, also plays heated sealed cable.
