Is characterized in that: the left box body and the right box body are opposite to form a rectangular box, an upper through hole is formed in the middle of the upper plane of the rectangular box, and a lower through hole is formed in the middle of the lower plane of the square box; the central lines of the upper through hole and the lower through hole are in the plane of the left box body opposite to the right box body; two side through holes are respectively arranged on the planes at the two sides of the rectangular box, and the central lines of the side through holes are in the planes of the left box body and the right box body which are opposite; a hot water pipe inlet and outlet hole is arranged in the middle of the plane of one side of the rectangular box; a heat dissipation coil pipe is fixed in the rectangular box; the water inlet end and the water outlet end of the heat dissipation coil pipe penetrate through the hot water pipe inlet and outlet holes; the rectangular box is filled with heat insulation materials. The effect is as follows: the temperature of the well mouth is increased from-8 ℃ to 23 ℃, and the purpose of well mouth heat preservation is achieved.
Description
Technical field
The utility model relates to the oil extraction in oil field technical field, and particularly production tree is the attemperator of a kind of production tree.
Background technology
In oil-field thick-oil is produced, often adopt the steam tracing pipeline that the single well production pipeline is incubated, steam arrives the back-pressure gate place and discharges by effluxing pipeline.Heat traced pipeline can only make the insulation of single well production pipeline, can not make the production tree insulation.Winter temperature is low, and the temporary transient stop pumping of oil well can cause the production tree frozen block, has a strong impact on production.For resuming production, use thaw production tree or use steam coach to thaw of well head steam tracing, take time and effort consumption wealth, and delay production.
The utility model content
The purpose of this utility model is: thermal circulating insulation case in a kind of production tree is provided, in the winter manufacturing process, for the production tree insulation, heat, can effectively solves the phenomenon of well head frozen block, and can improve the well head oil temperature, reduce viscosity of crude, be conducive to recover the oil and produce.
The technical solution adopted in the utility model is: thermal circulating insulation case in the production tree comprises left box body, right case and radiator coil tube.Left box body and right case are to adopt Plate Welding to become, and left box body is relative with right case to become a rectangular case, and it is characterized in that: there is through hole at the middle part on plane on the rectangular case, at the middle part of square case lower plane a lower through-hole is arranged; The center line of upper through hole and lower through-hole is in the left box body plane relative with right case; Two side planes at rectangular case have respectively two side through hole, and the center line of side through hole is in the left box body plane relative with right case; There is a hot-water line manhole appendix at middle part at a side plane of rectangular case; Be fixed with radiator coil tube in rectangular case, radiator coil tube is to the production tree heat supply; The hot-water line manhole appendix is passed in the water inlet end of radiator coil tube and water side; In rectangular case, be filled with heat insulating material.
The operating principle of thermal circulating insulation case in the summary production tree.Consult Fig. 1.Install: left box body 1 and right case 2 be relative to be buckled on the production tree and to be fixed together.Production tree bottom big four passes lower through-hole 6; Through hole 3 is passed on production tree top; Sleeve valve pipeline and the tubing valve pipeline of production tree pass respectively side through hole 4.Rectangular case wraps up production tree.Populated heat insulating material in the rectangular case.Radiator coil tube 7 passes into steam, and steam is incubator inside production tree heat tracing from radiator coil tube 7 processes, can improve the temperature of well head, and well head can frozen block.
The beneficial effects of the utility model: thermal circulating insulation case in the utility model production tree; be installed on the production tree; on the basis that does not change conventional incubation chamber; make wellhead temperature bring up to 23 ℃ from-8 ℃; avoided the generation of oil well frozen block phenomenon, even this well can not cause the well head frozen block owing to having a power failure yet; can directly start oil pumping machine oil pumping after the shutdown, reach the purpose of well head insulation.

Among the figure, 1-left box body, 2-right case, the upper through hole of 3-, 4-side through hole, 5-hot-water line manhole appendix, 6-lower through-hole, 7-radiator coil tube.
The specific embodiment
Embodiment 1: the thermal circulating insulation case is described in further detail the utility model as example in the production tree.
Consult Fig. 1.Thermal circulating insulation case in the utility model production tree comprises left box body 1, right case 2 and radiator coil tube 6.Left box body 1 is to adopt the Plate Welding of 5mm to become with right case 2, left box body 1 and right case 2 a relative rectangular case, the length 2300mm of rectangular case, height 2000mm, the thickness 560mm of becoming.A diameter is arranged is the upper through hole 3 of 250mm at the middle part on plane on rectangular case, the lower through-hole 6 that at the middle part of square case lower plane a diameter to be arranged be 400mm.The center line of upper through hole 3 and lower through-hole 6 is in the relative plane of left box body 1 and right case 2.At two side planes of the rectangular case side through hole 4 that two diameters are arranged respectively is 200mm, the center line of side through hole 4 is in the relative plane of left box body 1 and right case 2.The hot-water line manhole appendix 5 that at the middle part of a side plane of rectangular case a diameter to be arranged be 100mm.Be fixed with radiator coil tube 7 in rectangular case, radiator coil tube 7 is given the production tree heat supply.Hot-water line manhole appendix 5 is passed in the water inlet end of radiator coil tube 7 and water side.In rectangular case, be filled with heat insulating material.
Thermal circulating insulation case in oil well has been installed production tree.Before the installation, the well head production tree frozen block often occurs and causes this well stop pumping, could take out again after steam coach thaws.After installation, wellhead temperature is brought up to 23 ℃ from-8 ℃, has avoided the generation of oil well frozen block phenomenon, even this well can not cause the well head frozen block owing to having a power failure yet, can directly open and take out, and has reached the purpose of well head insulation.Remain dry with incubator surface behind the thermal circulating insulation case in this production tree, also prolonged incubator application life.
