Abstract

By studying the organic matter (OM) from the Mesozoic deposits of the Tyumen superdeep well (SG-6) as an example, deep zoning in the distribution, composition, and structure of heterocyclic components of the dispersed OM in catagenesis has been revealed. During mesocatagenesis, the composition of asphaltenes undergoes directed changes similar to those found for debitumenized OM. During apocatagenesis, polymerization and condensation of asphaltene molecules and their transition to an insoluble form as a new type of kerogen occur. Their lighter part is involved in structural redistributions inside resins and hydrocarbons (HC) and the formation of gases; there is a relative increase in the concentration of resins and HC (in wt % of residual bitumens). This circumstance should be taken into account when predicting the generation potential of OM and the composition of hydrocarbon fluids formed during catagenesis.

介孔和载脂催化区中分散有机物的树脂-沥青质组分的转化

摘要

通过研究秋明州超深井（SG-6）中生代沉积物中的有机质（OM），揭示了在催化作用中分散的OM的杂环成分的分布，组成和结构的深层划分。在介催化过程中，沥青质的组成发生直接变化，与脱沥青的OM相似。在脱氧催化作用期间，发生沥青质分子的聚合和缩合，以及它们作为新型干酪根转变为不溶形式。它们较轻的部分涉及树脂和碳氢化合物（HC）内部的结构重新分布以及气体的形成。树脂和HC的浓度（残余沥青的wt％）相对增加。
