Description
Technical field
The present invention relates to a kind of oil shale recovery technology, be particularly related to a kind of oil shale in-situ topochemical reaction method and extract the method for shale oil gas, the technology of the method and implementation method can cause local chemical reaction in subterranean oil shale layer original position and carry out the organic matter in cracked oil shale, thereby extract shale oil and fuel gas, and cracking reaction is completed to region carry out high waste heat circulation use.That one can realize oil shale in-situ cracking energy-autarchic and the maximized method of heat utilization ratio.Technique method can be widely used in the original position exploitation of solid or solidifying state fossil fuel (oil shale, coal, viscous crude).
Background technology
Two more than ten years in past, the rapid development of the whole world to energy demand, oil price also one creates the highest again.In 2012, the consumption of global crude oil reached 8,905 ten thousand barrels/day, the prediction of american energy office, and to the year two thousand thirty, oil extraction amount in the world's will arrive peak, can decline rapidly afterwards, and to the year two thousand fifty, minable crude oil will be progressively exhausted.Energy source in China situation is more urgent, and each large-scale oil field production capacity has started to decline gradually, and within 2012, oil interdependency has reached 57%, serious threat Chinese energy safety.Finding the alternative energy becomes the task of top priority, and oil shale becomes the major fields of countries in the world energy development with its huge reserves.
Oil shale is a kind of solid combustible organic sedimentary rock of high mineral content, composes and deposits not full ripe organic matter-kerogen, can obtain oil shale oil and oil shale gas through pyrolysis (low temperature distillation).In pyrolytic process, a series of physical-chemical reaction can occur, the heating initial stage can distill in conjunction with water, and kerogen is heated and changes into pitch subsequently, and heated bitumen further resolves into the fuel gas of shale oil, and last remnant organic matter and inorganic mineral progressively decompose.How in pyrolytic process, to control physical-chemical reaction, make oil shale pyrolysis Energy output, consumption rate the most reasonable, become the key factor of technical feasibility.
At present, the technology of oil shale extraction shale oil gas is mainly divided two large classes: earth's surface retorting technique and converted in-situ technology.Earth's surface retorting technique has been widely used in likes husky mud Asia, the U.S., China, Canada and Brazilian etc.But the concrete a lot of shortcomings of shale oil are produced in earth's surface destructive distillation: excacation amount is large, and cost is high; Easily form goaf, cause land subsidence; A large amount of residue treatment difficulty are large, and accumulating amount is large, easily causes secondary pollution; Discharge a large amount of waste gas and sewage big for environment pollution; Water supply volume is large etc.Comparing converted in-situ technology is by underground ore body is carried out to In Situ Heating, realize the underground heat solution exploitation of oil shale, do not destroy earth's surface, without goaf, and pile up without waste residue on earth's surface, environmentally safe, and can apply to the darker oil shale layer of buried depth, be a kind of method that has the hydrocarbonaceous SOLID MINERAL RESOURCES of bright prospects to develop.At present, the method for the underground lysisin situ of oil shale is had a lot.The underground conversing technology of famous shell (ICP) (patent No. CN87100890), Exxon Mobil ElectrofracTM technology (patent No. CN18975168A) is all that the mode that heats by conduction is to underground oil shale layer In Situ Heating, realize the gentle exploitation of shale oil, the method need to be transported to amount of heat underground, firing rate is slower, easily cause amount of heat loss, cost is higher, and due to the thermal expansion of oil shale, cause part closing up of cracks, reduce the permeability of oil shale, and the oil-air pressure producing is lower, cause oil gas recovery rate lower (list of references: gas industry the 29th volume paper " world's oil shale in-situ production technique progress " in 2009).
As far back as the seventies in last century, in the United States Patent (USP) " Shale oil recovery process using heated oil-miscible fluids " (No. 3515213rd, United States Patent (USP)) of Michael Pats application, propose to adopt hot volatile hydrocarbon vapor recycle to descend heatedly oil shale layer; Within 2004, Exxon Mobil is applied for a patent " hydrocarbon of gathering from impermeable oil shale " (patent No. CN18975168A), propose to adopt circulation of fluid, and be mainly that hydro carbons or water or saturated steam come heating oil rammell as heat transfer medium; Institutes Of Technology Of Taiyuan of China has also proposed by the method for Convective Heating oil shale for exploiting oil gas; Wherein in patent CN1676870A, disclose and passed through hyperthermia and superheating steam to flow transmission heating oil shale ore bed, in patent CN101122226A, openly adopted high pressure-temperature hydrocarbon gas as convective media.But these are as heat transfer medium by high-temperature vapor or hydrocarbon gas these high-temperature gases in the underground mode using Convective Heating oil shale, do not participate in oil shale in kerogenic cracking reaction process, and for guaranteeing the porosity and permeability on stratum, need apply for a long time higher liquid injection pressure, the short circuit that easily forms fluid is that rate of flow of fluid is too fast, does not just flow out stratum with oil shale heat exchange.And the heat absorption capacity coefficient of steam is low, cause heating slowly, water supply volume is large, and cost is increased; High temperature hydrocarbon gas has all proposed higher requirement to heating, injection device and stratum pipeline.In addition, within 2007, Chevron is applied for a patent CN200780013312.4, thereby propose to adopt the dense-phase fluid of normal temperature to realize physics fragmentation and the chemical modification kerogen extraction based products to oil shale layer to Injection Well circulation pressurization with step-down, wherein dense-phase fluid mainly adopts CO
2, the method is mainly by the variation of pressure and CO
2the thermal stress that phase transformation causes increases porosity and the permeability on stratum, and cost is higher, and technical difficulty is large.
Meanwhile, United States Patent (USP) 4483398,4552214 and 4703798 etc. discloses burning subterranean oil shale layer and has extracted the fire flooding of shale oil gas; Domestic many enterprises and colleges and universities have also proposed similar approach in succession; As patent CN102425399A advocates to adopt two vertical shaft patterns, deliver a gas in oil shale formation and at Gas Pipe stomion and fire by being arranged in wherein in a bite well fuel gas and oxygen channel, to realize the heating to oil shale layer, and by pressurization in Liang Koujing, oil shale layer is made to seam; In patent CN102383772A, advocate that the horizontal orientation well by being arranged in oil shale layer bottom comes light fluid rammell, blast oxygen rich gas by different passages and realize forward, reverse and fixed point gasification dry rectificating oil shale layer.And application number for 201310152389.7 and the application number patent that is 201310152533.7 in be to be all transported to heat that underground fuel gas and combustion-supporting gas the produce thermal source as destructive distillation subterranean oil shale layer by igniting.Though this underground combustion completely can provide a large amount of heat for the kerogenic cracking of oil shale, but this is a kind of mode of expendable exploitation, course of reaction is wayward, if it is improper to control, may consume a large amount of oil shales or kerogen, thereby reduced the recovery rate of oil shale, the relatively airtight environment of this external underground humidity, has higher requirement to ignition device and medium.
All there is the shortcomings such as cost is high, and efficiency is low, and thermal losses is large in the above-mentioned underground original position producing oil shale method of mentioning.
