Technical field
The utility model relates to a kind of system for geothermal production of electricity, especially a kind of system for geothermal production of electricity with honeycomb underground heat pipe well.
Background technique
Geothermal power is from earth depths, it arises from the melting magma of the earth and the decay of radioactive material, geothermal power not still free of contamination clean energy resource, if heat extraction speed is no more than supplementary speed, so heat energy or reproducible, along with the increasing of in short supply, the external pressure of global range fossil energy, people more and more pay attention to for settling accounts reproducible green energy resource.
Present stage geothermal power exploitation still by the impact of factors, as geological condition, drilling technique etc., at present, prior art injects water or cryogenic fluid by electric energy to underground mostly, water after heat exchange of heating is drawn up ground for people, because the stratum, water-bearing layer of being rich in geothermal power is positioned at km extremely a few km depths at the end, ground mostly, need huge pressure water could be injected, need at substantial electric energy, in addition extract hot water and also need at substantial electric energy, therefore geothermal power is extracted also very huge to expending of electric energy, therefore the energy needed for geothermal energy development how is reduced, also to well heat injection water simultaneously, become problem in the urgent need to address.
Model utility content
For solving the problem, the utility model provides a kind of honeycomb system for geothermal production of electricity, water filling is reduced greatly with the institute's energy requirement that draws water, increase heat exchange pipeline and reservoir formation-engaging surfaces increase simultaneously, all effectively can extract the geothermal power in each region of whole heat exchange layer, promote extraction rate and the extraction efficiency of geothermal power greatly.
For achieving the above object, the utility model adopts following technological scheme:
Comprise water injection well 1, hot well 2, geothermal power generation plant 4, described water injection well 1 and hot well 2 interval arrange and are drilled into target zone downwards by earth's surface, the described water injection well 1 shaft bottom mouth of pipe and the hot well 2 shaft bottom mouth of pipe are by horizontal well 3 UNICOM, described water injection well 1, hot well 2 and horizontal well 3 form nearly U-shaped tubular construction, described horizontal well 3 is made up of several horizontal pipe that is parallel to each other, described horizontal pipe in the vertical direction multilayer is uniform, described each pipeline one end is converged and is connected with the water injection well 1 shaft bottom mouth of pipe, the other end converges and is connected with the hot well 2 shaft bottom mouth of pipe, described hot well 2 upper end well head connects the water intake 41 of geothermal power generation plant 4, the water outlet 42 of described geothermal power generation plant 4 connects the water filling hole 11 of water injection well 1 upper end by water injection pump 5.
Wherein, the longitudinal section of described horizontal well 3 is cellular.
Wherein, the convergent point that the horizontal pipe forming described horizontal well 3 is converged by its two ends and pipeline itself form class Olive Shape profile jointly.
Wherein, the layer between every layer of horizontal pipe is apart from being 100 meters, and in same layer horizontal pipe, the level interval between pipeline and pipeline is 100 meters.
Wherein, described water injection well 1, hot well 2 length direction are all vertical with horizontal plane.
The beneficial effects of the utility model are: honeycomb system for geothermal production of electricity of the present utility model passes through water injection well, pumped well and horizontal well form nearly U-shaped tubular construction, water injection well end is made to be tending towards equal with the pressure of pumped well end, greatly reduce water filling resistance, make water injection well 1 end can easily to water filling in passage 3, simultaneously pumped well 2 end also only needs to expend a small amount of electric energy and can extract out from depths at the bottom of ground by the water after heating or working medium, greatly improve the extraction efficiency of geothermal power, utilize between the upper and lower every the cellular underground heat pipe well be arranged in parallel simultaneously, the heat of end heat exchange layer farthest extracts over the ground, improve the utilization ratio of geothermal power, improve heat exchange efficiency.
