Abstract
The utility model discloses a heat source system for power generating and oil transportation heat tracing in petroleum well secondary development. An airtight hollow shaft is composed of a petroleum well casing pipe and a bridge plug, a heat insulation pipe column is arranged in the airtight hollow shaft, a screen pipe is installed on the lower portion of the heat insulation pipe column, a bottom cap head is installed on the lower portion of the screen pipe, a ground well opening is provided with a heat insulation pipe hanger and connected with the heat insulation pipe column, and therefore a geothermal source system is formed. The geothermal source system is connected with a manifold control system and an equipment system, and the heat source system for power generating and oil transportation heat tracing in petroleum well secondary development is formed. Circulatory mediators enter the annular space between the petroleum well casing pipe and the heat insulation pipe column through the pipe column hanger, enter the heat insulation pipe column from the screen pipe on the upper portion of the bottom cap head, and pass through the heat insulation pipe hanger and enter the manifold control system from an upper portion outlet to form a heat conduction mediator closed cycle heat source system, hot water is outputted after heat exchange is conducted by the equipment system, and heat is provided for heat tracing of a petroleum transportation pipeline or power generating of a heat energy generator. According to the heat source system for power generating and oil transportation heat tracing in petroleum well secondary development, a petroleum well is transformed into a geothermal well, development and utilization of deep geothermy are achieved, energy is saved, and the environment is protected.
Description
Technical field
The utility model relates to deep geothermal heat, low-temperature electricity-generating and petroleum industry oil transportation companion thermal technology field, and hot heat source system is accompanied in the generating and the oil transportation that are specifically related to oil well secondary development.
Background technique
In petroleum industry petroleum production process, oil well oil pump capacity can decline year by year, the extraction value of many oil wells is also declining, annual oil well and the water injection well quantity increasing year by year produced of suspending, take Liaohe Oil Field as example, reach thousands of mouthfuls because suspending the idle oil well quantity of production, and these oil wells are because management difficulty is large, for a long time need not after cause casing corrosion serious, finally abandon it.Nowadays along with the cost promotion year by year of recovering the oil, energy-conservationly important synergy means have been become.Through measuring and calculating, the individual well 3000m degree of depth, utilizes its deep geothermal heat can pass through generator set generating per hour 30-50 degree, and thousands of degree can generate electricity for one day.Utilize in the winter time deep geothermal heat can pass through companion's heat of heat pump unit petroleum pipeline, can save a large amount of fire coals or rock gas.The energy 98% that the thermal source of Liaohe Oil Field heat traced pipeline is used is rock gas, and 2% is crude oil and heated by electrothermal film.The annual gas production in oil field is 700,000,000 m
3, and companion's heat loss rock gas reaches 200,000,000 m
3, economic value is up to 5.0 hundred million yuan, and wherein this does not also comprise the production of boiler and the correlative charges of maintenance maintenance.To the waste defect of the above-mentioned energy and equipment, there is no so far good technological scheme and solve.
Summary of the invention
Based on above technical background, the purpose of this utility model is planned oil well and is carried out second development and utilization, extend the life-span of oil well and still can pump in job execution in the future on the one hand, utilize on the other hand the oil well of transformation that folk power supply, oil transportation companion's heat and space heating service are provided, reach the effect of killing two birds with one stone.
Oil well is transformed into the heating arrangement of geothermal power generation unit, core is to utilize increasing progressively and heat conduction basic principle of stratum different depth step temperature, do not extract a water in stratum, the real underground heat new technology development pattern that realizes " heat-obtaining does not draw water ", thus the secondary pollution to stratum petroleum resources avoided.
In order to achieve the above object, the generating of oil well secondary development of the present utility model and oil transportation accompany hot heat source system to realize in the following manner: with oil well sleeve pipe and bridging plug composition confined air pit shaft, screen casing is installed in the built-in adiabatic tubing string of confined air pit shaft, heat-insulated pipe column bottom, bottom cap head is installed in screen casing bottom, ground well head is installed adiabatic hanger and is connected adiabatic tubing string, composition geothermal heat source system, geothermal heat source system connects manifold control system and device systems, and hot heat source system is accompanied in generating and the oil transportation of the secondary development of composition oil well.
Programmed sequence of operations: circulatory mediator is entered by annular space between oil well sleeve pipe and adiabatic tubing string by heat-insulated pipe hanger, enter adiabatic tubing string by the screen casing on a bottom cap top again, through heat-insulated pipe hanger by top outlet through manifold control system forms heat-conducting medium closed-circuit heat source system and by device systems heat exchange after export hot water heating and accompany heat or thermal power generator to generate electricity to oil transmission pipeline.
The beneficial effects of the utility model are: will discard oil well and be transformed into geothermal well, and realize the exploitation of deep geothermal heat, and have huge economic benefit and social benefit, energy-conserving and environment-protective.
