The present invention is mainly characterized in that after coming water from a combined station 1 is heated by a solar-energy receiving and storage device 2 and a solar-energy heat collection pipe bundle 5, the coming water is injected into a ground layer. The present invention has the advantages that heating is carried out to the injected water by solar energy in order to perform the functions of improving the temperature of an oil layer, reducing the viscosity of original oil, improving the pressure of the oil layer, and gradually improving the temperature of produced liquid, and a mode of mechanical oil collection can be changed into a mode of automatic oil collection; thus, electric energy and fuel can be saved, and the benefit of the yield increase of petroleum is obvious; the social benefit lies in that due to the reduction of burning amount, the pollution of sulfur dioxide and dust to the atmosphere can be reduced.
Description
Technical field the invention belongs to the oil development field, especially refers in oil development the utilization to solar energy.
Background technology many oil wells in the oil development of routine change mechanical oil well into by original flowing well, also have many oil wells to begin just to carry out mechanical oil recovery, and both of these case is all because of due to the energy shortage of oil reservoir.It to oil-bearing stratum flooding one of method that increases the oil reservoir energy, the most extensive employing at present be the low temperature water filling, promptly to the water injection oil reservoir of not heating, even inject the hot water of deviating from, but when this water arrived water injection well through uninsulated buried pipeline, the annual mean implantation temperature of water should be same as local annual mean ground temperature.With each oil field of Jing Bei is example, and according to the ground temperature data of this section, how high the temperature no matter water injecting pump is exported is, and water can be above 15 ℃ through the year-round average temperature of uninsulated buried pipeline arrival water injection well.When the water at low temperature of injecting after oil reservoir carries out interchange of heat, oil gas water when getting back to multi-purpose station, for the sewage of being deviate from once more, is to have finished once to annotate to adopt circulation from oil well produced, for oil reservoir, is to have carried out, a temperature-fall period.Because this circulation is continuous, seeing does not on the whole have obvious periodic, but there is any to affirm, be exactly that the low temperature water yield passed through in the oil reservoir is big more, the temperature drop speed of oil reservoir is fast more, inject progressively increasing of oil reservoir amount and force reservoir temperature close to the temperature of water at low temperature gradually along with water at low temperature in other words, this circulation to take oily effect very low.This is because when water at low temperature is injected oil reservoir by the water injection well tubing string, interchange of heat also begins thereupon, if crude oil solidifies the temperature that is higher than water, oil water boundary can form the oil film that one deck solidifies because of the interchange of heat factor, the oil film that this layer solidifies relies on the rock stratum of micro-pore to be enough to bear the pressure of tens Mpa, can cause beginning annotating and not intake; Prolongation along with the time, ground temperature can dissolve the oil film that this layer solidifies, under powerful pressure effect, injecting water can rapidly advance in the instant of solidifying rupture of oil film, the rock stratum can produce the crack because of the sudden change of sudden pressure and temperature, if this crack feeds through to the rock stratum of closing on oil reservoir, then can cause idle water filling.The most difficult road of walking of fluid-mixing is the rich oil district, will secondly be oil-poor district through supersolidification, obstruction, dissolving and current several steps all because cryogen arrives crude oil whenever, and the road that likes best away is the crack.If there are many cracks to be communicated with between the oil-water well, then these cracks will become the passage based on the fluid-mixing of water, and these passages and parallel pipeline have similarity, and they all have possibility stifled by coagulating, paraffin blockage, only otherwise stopped up by solid matter, the dissolved chance of opening is all arranged.Surround large-area oil field between passage and the passage, exploit these oil fields, the main method of exploiting these oil fields is to widen passage, for the progress of widening the soonest of low temperature driving, rely on ground temperature to dissolve blocked passage repeatedly exactly, this is high moisture low output reason.Heat and waterflood-transmission line all is incubated if all are injected water, the water temperature that arrives well head is reached more than 100 ℃, fuel will exhaust 10～20% output and a large amount of construction investments, and the difficulty that realizes is very big.
Summary of the invention the present invention proposes a kind of method of utilizing the solar energy recover petroleum, crosses low this technical problem with solution water filling temperature in the stratum.The technical scheme that the present invention takes is: this method includes photophase production procedure and no photophase production procedure,
The photophase production procedure is wherein arranged:
Entering solar energy from the current of multi-purpose station 1 through valve 11 receives and stores device 2, water is heated to 60～90 ℃ in this device, this water enters water injecting pump 3 through valve 10, valve 14, after this water injecting pump pressurization, enter solar energy heating tube bank 5 through valve 15, valve 21 again, this water this solar energy heat collection pipe is intrafascicular be heated to 120～300 ℃ again after, enter the stratum to water injection well 6, the production fluid in the stratum is transported to the multi-purpose station 1 through collector and delivery pipe 8 from oil well 7.
No photophase production procedure:
The solar energy reception stores device 2 stored water and enters circulation pump 4 through valve 12, valve 16, after these circulation pump 4 pressurizations, enter supplementary heater 9 heating through valve 17, valve 18 again, flow out after valve 19 enters solar energy heating tube bank 5, or come out after valve 20 enters solar energy heating tube bank 5 from valve 17, this water is behind water injection well 6 well heads, get back to the solar energy reception through solar energy heating tube bank 5, valve 22, valve 13 again and store device 2, get back to multi-purpose station 1 from oil well 7 through collector and delivery pipe 8 by the oil gas water that has the photophase to store in the oil reservoir simultaneously.
The flow process and the operating principle of this method are: when the photophase is arranged, store device receiving through solar energy from the multi-purpose station 1 pre-water that injects, carry out the first step and be warmed to 60～90 ℃, outer defeated by water injecting pump 3 pressurizations afterwards, through the intrafascicular water injection pipe of solar energy heating the time, to inject water and carrying out for second step and heat up, temperature can reach 120～300 ℃ when arriving the water injection well well head, enter oil reservoir through the high thermal resistance tubing string of water injection well, in oil reservoir with oil reservoir in material carry out interchange of heat.The result of interchange of heat, the one, crude oil in the oil reservoir can not occur and freeze and annotate the phenomenon of not intaking; The 2nd, the characteristic that based on crude temperature rising viscosity descends, and think that in conjunction with oil reservoir inner horizontal warp-wise seepage flow general formula the viscosity of crude oil low yield more is high more; The 3rd, according to the characteristic that material expands with heat and contract with cold, the material in the oil reservoir is met heat and will be expanded, and causes the strata pressure around the water injection well to rise, and high yield is high more more to think water injection well strata pressure on every side in conjunction with oil reservoir inner horizontal warp-wise seepage flow general formula; The 4th, according to the analysis of water drive oil ultimate recovery design formulas, reservoir temperature rising viscosity of crude descends, and certainly will cause the rising of ultimate recovery; The 5th, think there are not low abundance oil reservoir, heavy oil tested layer and the oil-poor oil field etc. of extraction value for conventional development technology technology, adopt this method exploitation that extraction value is then arranged, because it is efficient and cheap that solar energy directly is used in oil exploitation, this invention can increase the recoverable reserves of oil exploitation on the earth.
The invention has the advantages that by adopting solar energy that water filling is heated, play and improve reservoir temperature reduction viscosity of crude, improve formation pressure, progressively improve the production fluid temperature, can change mechanical oil recovery into oil flow production, exploitation can be cancelled supplementary heater mid-term, therefore can saves energy and fuel; The oil output benefit is obvious, can increase crude output, improves rate of oil production, improves ultimate recovery and increase recoverable reserves; Because the raising management benefit of rate of oil production will improve with it; Social benefit is because the reduction of quantity combusted can reduce the pollution to atmosphere of sulfur dioxide and flue dust, because the reduction of workover treatment amount, quantity of wastewater effluent reduces relatively, and degree of contamination such as farmland, grassland and water source are descended; Also reduce relatively through measuring and calculating analysis project cost in addition, mainly occur in cancellation three and take out equipment, do not establish an investment such as block station and measuring station.
