关于碳酸盐岩生油潜力的研究

碳酸盐岩有着良好的沉积环境,丰富而质优的有机质来源,作为其有机质丰度指标的有机碳含量（TOC）和氯仿沥青＂A＂含量相对较低,同时由于碳酸盐岩内不含或含有很少的粘土物质,所以粘土物质的催化作用对其大量生烃不起作用,因而只有碳酸盐岩埋藏足够深才能达到生烃的温度。本文就沉积环境、有机质来源、类型、衡量指标、促使有机质生烃作用等碳酸盐岩的生油条件探讨了碳酸盐岩的生油潜力。

Research on genetic potential of the carbonate rock

Being relative to the types of the argillaceous rock,carbonatite has special oil and gas source conditions,such as good sedimentary environment,rich and high organic sources,abundance indexes of the organic matter of it;organic carbon content（TOC） and chloroform bitumen ＂A＂ content are relatively lower.And because the carbonatite does not contain or contains a spot of clay material,so the catalysis of clay material doesn＇t work for lots of hydrocarbon generation,thus only carbonatite is buried deeply enough to moderate temperature to generate hydrocarbon.The oil source potentiality was discussed from the oil generating condition including sedimentary environment,source and type of organic material,evaluating index and prompting function of organic hydrocarbon generation.
