沉积岩层被埋没后,烃源岩中有机物的成熟和储油砂岩中无机成岩作用是自然的结果。通过综合储油层源岩体系的渐进成岩的作用过程特征,就能预测潜在的烃类储集层中孔隙度和渗透度增强的分布。种种观测表明,提高砂岩中铝硅酸盐和碳酸盐溶解度的有机溶剂,可以通过加热或氧化裂解羰基团和酚醛基团得到,这些羰基团和酚醛基团是来自邻近源岩的油母岩。例如,油母岩核磁共振(NMR)谱表明,边缘的羰基团和酚醛基团,在液态烃产生之前,就从油母岩分子中分离出来了。
After the sedimentary rock is buried, the organic matter maturation in the source rock and the inorganic diagenesis in the oil-storing sandstone are the natural results. By integrating the process characteristics of progressive diagenesis of the reservoir s source rock system, it is possible to predict the distribution of enhanced porosity and permeability in potential hydrocarbon reservoirs. Various observations indicate that organic solvents that increase the solubility of aluminosilicates and carbonates in sandstones can be obtained by heating or oxidizing the cleavage of carbonyl groups and phenolic groups which are kerogen from adjacent source rocks . For example, the kerogen NMR spectrum shows that the carbonyl and phenolic groups at the edges are separated from kerogen molecules prior to the production of liquid hydrocarbons.
