Description
The present invention relates to a method and equipment for extracting and processing petroleum, in particular, it relates to a method and equipment for producing light hydrocarbon by using microwave pyrolysis petroleum and recovering it.
Petroleum is one of the main energy forms in the world today, and the technological development of petroleum production is rapid because petroleum production is an important part of petroleum production. However, there are places where current mining techniques can be put to practical use. For example: the thick oil in the ground is not easy to be exploited. The data show that the underground oil recovery rate is 40-80%, and the oil is harder to recover as the oil is thicker. People think of a plurality of methods to improve the recovery rate of the thickened oil. One of them is thermal recovery method, which burns the recovered petroleum to generate steam, presses the steam into the ground, heats the thick petroleum to increase its fluidity, and is convenient for recovery. Because the action distance of the steam is short, the underground pressure is high, and the high-temperature steam is easy to be transformed into water; because of the hydrophobic property of petroleum, the water and petroleum are not well jointed, the energy waste is large, 10% of produced oil needs to be burnt, the equipment investment is large, and the effect of the thermal production method is not very ideal. The other method is to utilize light hydrocarbon matter to dissolve the thick petroleum to increase the flowability of petroleum and to press it into underground to dissolve the thick petroleum for easy exploitation. However, because of high price of light hydrocarbon, the transportation is inconvenient, and the method is not suitable for being widely applied in oil fields.
The invention aims to provide a method for producing light hydrocarbon recovery by using microwave pyrolysis petroleum and a miniaturized device thereof.
The invention is realized by the following steps: pumping part of the produced petroleum, especially thick oil, into a heater, heating to 50-200 deg.C, and microwave cracking into light hydrocarbon under the action of catalyst in the microwave cracking furnace. Then the mixture is sent into a storage tank, is pressed into the ground by an injection pump, and is well combined and dissolved with the thick petroleum in the petroleum reservoir after passing through the underground petroleum reservoir to form petroleum with good fluidity, so that the petroleum can be conveniently pumped out by an oil well pumping unit.
The reaction of cracking the thickened oil into light hydrocarbon by microwave under the action of a catalyst is as follows: +CH2＝CH2+CH3(CH2)mCH＝CH2
the flow velocity of the heated petroleum in the microwave cracking furnace is 0.5-1.5 m/min, and the conversion rate is about 30-70%.
The microwave cracking furnace can be used in series or in parallel according to the situation of an oil field site. The parallel connection can improve the treatment capacity, the series connection can improve the cracking conversion efficiency, and the furnace chambers can be shared when the series connection is carried out, so that an integral structure is formed. The use of multiple microwave pyrolysis furnaces allows the power of each microwave source to be made smaller.
The microwave cracking furnace consists of microwave source, waveguide tube, coupler, furnace cavity and heat insulating layer. The coupler is sleeved outside the furnace chamber, the input port of the coupler is connected with the microwave output port of the microwave source by a waveguide tube, one or more groups of catalyst supports are placed in the furnace chamber, each group consists of a left disc and a right disc, the middle part of the catalyst supports is provided with a mounting hole, if the catalyst supports are used by a plurality of groups, the catalyst supports can be connected by a pull rod, and the bottom of each disc is provided with a plurality of oil passing holes with the diameter of phi 3 to-8 mm. The heat insulating layer is laid outside the oven cavity and the coupler to reduce heat loss. The coupler and the furnace chamber can be made into a circular shape or a square shape.
The furnace chamber consists of a furnace end and a furnace body. The furnace end is conical, and an oil inlet, one or more flushing ports and an oil return port are arranged at the small end of the furnace end. The big end is provided with a flange which is connected with the furnace body by bolts. The furnace body is in the shape of a wine bottle, and a reaction mixed oil output port and one or more flushing ports are arranged at the small end of the furnace body. The furnace chamber, the catalyst support, the pull rod and the like are made of medium materials with small microwave absorption, such as: glass, pottery, plastic and other materials.
The invention has the advantages of simple equipment, low investment, high recovery efficiency, convenient size adjustment and capability of being completed in the oil field on site.
