Recovery Method and Application for Primary State of Source Rock Richness and Type
-
摘要: 本文应用源岩中残烃含量及在热解仪－微机联机系统上开发的成熟度新参数，建立了对低成熟—高成熟（任意丰度、类型、岩性等）烃源岩原始有机质丰度和类型的恢复方法（残烃法）。并应用热解及有机碳分析结果，依据沉积岩石学、有机岩石学等基本原理、干酪根降解生油理论，以及石油有机地化人员在生产科研过程中常用的三个定义式及一个公认的假设为前提，建立了对低成熟—过成熟（任意成熟度、丰度、类型、岩性等）烃源岩原始有机质丰度的恢复方法（有机无效碳法）。因有机无效碳含量与源岩演化程度无关，因此该方法适用于任意成熟度烃源岩原始有机质丰度的恢复，较好地解决了高成熟过成熟烃源岩原始有机质丰度的恢复问题。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.
