Description
Technical field
The present invention relates to oil exploration technology field, particularly a kind of assay method of mud shale series of strata organic carbon content.
Background technology
The successful Application of large-scale volume fracturing technology, not only makes non-source sequence but very fine and close reservoir Crude Oil is successfully commercialized, and 2013, Chinese Ordos Basin tight reservoir crude oil output exceeded 2,000 ten thousand tons; U.S.'s tight reservoir crude oil output reaches 9,700 ten thousand tons.The successful Application of large-scale volume fracturing technology, equally also makes the crude oil preserved in hydrocarbon source rock series of strata be able to business development and becomes possibility, and the successful exploitation as U.S. Eagle ford oil shale fuel just has benefited from the large-scale volume fracturing technology of batch production.Conventional oil stock number is about 4,878 hundred million tons in the world, and the stock number of oil shale fuel reaches 47,000,000,000 tons, and the potentiality of exploratory development are very large.
Organic carbon content typically refers to the content containing organic carbon in rock, is the important indicator that hydrocarbon source rock series of strata organic matter is evaluated, and is usually used in evaluating hydrocarbon source rock series of strata abundance of organic matter height, and therefore, also Chang Zuowei calculates the important parameter of hydrocarbon resources.Usually total content of organic carbon analysis in rock is carried out by GB/T19145-2003 standard, Method And Principle is after removing the inorganic carbon in sample with watery hydrochloric acid, burn in high temperature oxygen air-flow, make total organic carbon be converted into carbon dioxide, detect through infrared detector and provide the content of total organic carbon.In hydrocarbon source rock, organic carbon comprises three parts, kerogen, liquid state organics and gaseous hydrocarbon, and in conventional analysis organic carbon process, when rock sample pulverizing and acid treatment, gaseous hydrocarbon and operative liquid organic matter has been made to lose, therefore, for hydrocarbon source rock, total organic carbon comprises two parts, one is organic carbon content in the kerogen not also being evolved into oil in rock, and two is the content of organic carbon in liquid organic (comprise crude oil that kerogen generated but still be stranded in rock and not discharge and original liquid organic).Though the organic carbon recorded in the method neither represents original organic carbon content in rock, do not represent organic carbon content in kerogen solid-state in rock yet.But the background that the method is drafted is assembled for conventional oil and formulates, conventional oil gathering background is hydrocarbon source rock and reservoir is not usually same layer position, crude oil is expelled in reservoir rock to assemble from hydrocarbon source rock needs certain migration distance usually, can distinguish hydrocarbon source rock and reservoir with other method is clear.Therefore, only need to measure organic carbon content in hydrocarbon source rock, under identical conditions, the height of organic carbon content represents the height of abundance of organic matter in hydrocarbon source rock; Reservoir is then non-petroleum source bed, does not need to carry out organic carbon analysis.And in mud shale series of strata, the usually symbiosis of hydrocarbon source rock and reservoir rock, lithology is mostly the middle lithology of mixing, as silty or white clouds matter mud stone, pelitic siltstone or argillaceous dolomite etc., under naked eyes or microscope, carry out Rock Name acquire a certain degree of difficulty, hydrocarbon source rock and reservoir are usually differentiated unclear, reservoir also may have certain hydrocarbon generation capacity, and hydrocarbon source rock also may become reservoir under certain condition.In this case, in rock, liquid organic matter all has larger impact on total organic carbon contribution to this area's Evaluation of source rocks, the calculation of crude resources gauge.If liquid organic contribution is far longer than kerogenic contribution in rock, then rock may mainly as reservoir, if liquid organic contribution is far smaller than kerogenic contribution, then rock may mainly as oil-degrading bacteria, if liquid organic matter and kerogenic contribution all occupy certain proportion, then oil shale fuel may be had in rock to assemble.
Known based on above-mentioned analysis, at present for organic carbon determination method mainly based on conventional oil assemble background formulate, these methods are only applicable to conventional oil exploration assessment.But because the liquid organic part to total organic carbon contribution can not distinguish effectively, thus be not suitable for can as the organic carbon determination of the mud shale series of strata of reservoir and abundance of organic matter evaluation.
