Abstract
The technological process for oil development by using solar energy is divided into technological process of light period production and technological process of no-light period production, and is mainly characterized by that the water coming from combined station is passed through the solar energy receiving and storing device and solar energy collection pipe column, heated and injected into stratum, and its advantages lie in that it utilizes solar energy to heat injected water to raise temp. of oil-bearing stratum, reduce viscosity of crude oil, raise oil layer pressure and progressively raise liquid temp. and can change the mechanical oil recovery to flowing oil recovery, and can save electric energy and fuel, and reduce environmental pollution.
Description
The invention belongs to the oil development field, especially refer in oil development the solar energy utilization.
Many oil wells change mechanical oil well into by original flowing well in the oil development of routine, 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 temperature-fall period one time.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 former oil freezing point is higher than the temperature of 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 likeing best fixed road 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, the main method of exploiting these oil fields is to widen passage, and the progress of widening the soonest for low temperature drives relies on ground temperature to dissolve blocked passage repeatedly exactly, and this is the reason of high moisture low output.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.
The object of the present invention is to provide a kind of technology of utilizing solar energy as the main energy sources in the oil development, promptly utilize solar energy that the water that injects oil well is heated.
