Abstract: Based on the residual hydrocarbon content in source rocks and the developed new parameters of ma-turity in the rock-oval computer system,this paper presented a recovery mathod for the abundance of pri-mart' organic matter in low to high-mature source rocks( any abundance, type and lithology).It is knownas the residual hydrocarbon method. Based on the data from rock pyrolytic and organic carbon analyseswith the basic principles in sedimentology and organic petrology, on the theory of oil generation of kero-gen decomposition, and on three defiidons and an acknowledged hypothesis which researchers oftenuse, this paper presected a recovery method of the abundance of primary organic matter for low to over-mature sour cerrocks(any maturity,abundance, type and lithology).It is known as the organic ineffective carbon method. because the content of the organic ineffective card on has nothing to do with the evolu-tional degree of source rocks, this method is applicable to the recovery of the abundance of the primaryorganic matter for source rocks with any maturity,especially to solve the recovery of the abundance ofthe primary organic matter for high or over-mature source rocks.
