Abstract
The utility model belongs to the sleeve pipe gas recycle system device who uses in the oil gas field development field, including CNG roping sled car 1, CNG prizes tinning 2, gas -fired heater 3, two hollow bar hot -water circulation devices 4 and beam -pumping unit 5, the back is retrieved with the low -grade sleeve pipe gas in the oildom to CNG roping sled car 1, transport to the well site CNG sled tinning 2 of packing into, the tinning 2 of CNG sled provides the gas for gas -fired heater 3, gas -fired heater 3 carries out circulation heating with the hot water in two hollow bar hot -water circulation devices 4, accompany heat for liquid in the pit shaft of beam -pumping unit 5, mobility with liquid in the assurance pit shaft, the normal operating that keeps the oil well.
Description
Technical field
The utility model belongs to the casing gas recycling system device applied in oil-gas field development field, especially at the device needing to carry out the oil well of the recovery of low-tension bushing gas and the heating of ground, well site is applied.
Background technology
In oil-gas field development field, some oil wells have associated natural gas and separate out, and this part gas pressure is less, sometimes reclaims more difficult; And on other oil wells, because wax content in crude oil is high, freezing point height recovery process needs to carry out companion's heat, the companion's hot mode taked at present mainly contains electric tracing and two hollow stem hot water circuit companion heat.The companion's hot mode applied in patent ZL200820226294.X, for the remote high-solidifiability oil well without source of the gas or source of the gas scarcity, needs to adopt coal-fired mode to heat circulating hot water.
Utility model content
The technical scheme that this utility model adopts designs suitable CNG skid tank, be placed to and need to carry out, on the oil well site that heats, utilizing the low-grade casing gas in CNG roping Qiao Che recovered oil district, being transported on well site, load CNG skid tank, for wellsite heater.This utility model utilizes the low-grade casing gas in CNG roping Qiao Che recovered oil district, can make full use of low-grade energy, can save oil field development cost, and favourable to environmental protection; Well site adopts CNG skid tank natural gas-storing, can save the cost laying long distance line; Well site heating adopts natural gas than adopting coal more environmental protection manageability.
Accompanying drawing explanation
Accompanying drawing 1 is casing gas recycling system device schematic diagram, and wherein 1 is CNG roping sled car, and 2 is CNG skid tank, and 3 is gas-fired heater, and 4 is two hollow stem hot water circulating devices, and 5 is oil pumper.
After low-grade casing gas in oily district reclaims by CNG roping sled car 1, transport to well site and load CNG skid tank 2, CNG skid tank 2 provides combustion gas for gas-fired heater 3, hot water in two hollow stem hot water circulating device 4 is carried out circulating-heating by gas-fired heater 3, for liquid in the pit shaft of oil pumper 5 carries out companion's heat, to ensure the mobility of liquid in pit shaft, keep the normal operation of oil well.
Detailed description of the invention
As accompanying drawing 1, after low-grade casing gas in oily district reclaims by CNG roping sled car 1, transport to well site and load CNG skid tank 2, CNG skid tank 2 provides combustion gas for gas-fired heater 3, hot water in two hollow stem hot water circulating device 4 is carried out circulating-heating by gas-fired heater 3, for liquid in the pit shaft of oil pumper 5 carries out companion's heat, to ensure the mobility of liquid in pit shaft, keep the normal operation of oil well.
