Abstract
The utility model relates to a heat thickened oil recovery device using heat conduction oil, which is used for the exploitation of thickened oil and ultra thickend oil. The utility model is composed of a special purpose wellhead device 1, a 2'/2' oil tube column 2, a 4' oil tube column 3, a current divider 4 for heat conduction oil, a sieve tube 5, a bottom valve 6, a sealing device 7, an insertion tube 8, an oil well pump 9, a sucker rod 10, and a telescopic tube 13. The utility model adopts the heat conduction oil as working media which can completely meet the requirements of the exploitation of the thickened oil and the ultra thickened oil when the heat conduction oil is used, with the advantages of reliable operation, energy saving, and the reduction of production cost.
Description
The utility model relates to a kind of conduction oil that is used for viscous crude, super heavy oil recovery and accompanies hot thickened oil recovery device.
Viscous crude, super viscous crude be because of its viscosity height, mobile extreme difference, and the exploitation difficulty is very big, need take thermal methods such as steam injection pit shaft, ground companion's heat and corollary apparatus to exploit.At present, the main electric heating hollow rod that adopts of the on-the-spot pit shaft heating of adopting is usually got over the pump heater, though electrically heat tracing pit shaft mode of heating can reach the purpose of viscosity reduction exploitation, because of power consumption is big, the cost of production height is affected its economic benefit.
The purpose of this utility model is to provide a kind of can satisfy viscous crude, super heavy oil recovery requirement, saves energy, the conduction oil that reduces production costs are accompanied hot thickened oil recovery device greatly again.
The utility model is to realize like this.This kind conduction oil accompanies hot thickened oil recovery device by special-purpose wellhead assembly with by 4 " oil pipe, 4 " telescoping tube, 2
1/ 2 " oil pipe, 2
1/ 2 " two pipe system that constitutes of telescoping tube and sucker rod, oil well pump, conduction oil current divider, insertion tube, packer, screen casing, bottom valve are formed, and its assembling, architectural feature are as follows: 2 of special-purpose wellhead assembly
1/ 2 " tubing hanger and 4 " tubing hanger lower end has been hinged with 2 respectively
1The inside and outside double layer oil pipe post in/2 " and 4 " is assembled with the thermal compensation telescoping tube respectively on the two cover tubing strings; 4 " the tubing string lower end is assembled with thermal packer, and 2
1/ 2 " the tubing string bottom is assembled with oil well pump, conduction oil current divider, insertion tube, screen casing and bottom valve successively, and the oil pump plunger piston upper end links to each other with sucker rod.The course of work of this device is as follows: the conduction oil in the heat conduction oil tank is squeezed into the down-hole by oil pump through special-purpose wellhead assembly, along 2 after the heating furnace heating
1Circular passage between/2 " oil pipe and 4 " oil pipe flow to the shaft bottom, to 2
1/ 2 " the extraction crude oil in the oil pipe plays companion's heat effect; After conduction oil is flowed through and is installed in the current divider of dual string lower packer top, by returning to well head on the annular space between 4 " oil pipe and 7 " sleeve pipe, and be recycled in the heat conduction oil tank along surface line.So repeatedly, conduction oil moves in circles according to said process, can finish pit shaft companion thermal recovery oil and the defeated whole work of ground companion's heat collection.
Conduction oil provided by the utility model accompanies hot thickened oil recovery device to adopt conduction oil as working media, and reliable operation is respond well, utilize it can satisfy the requirement of viscous crude, super heavy oil recovery fully, saves energy reduces production costs greatly, is suitable for and applies.
