“岩心录井”是指在钻井过程中,用专用工具,将井下岩石柱体取到地面,并对其进行分析,研究,从而取得各项资料的过程。取出的岩石柱体称为“岩心”。岩心是最直观最真实全面反映岩石特征的第一性资料。通过对岩心的分析,研究,可以根据岩性,岩相特征推断沉积环境,储集层的分布,并可获得生油层特征及生油指标,储集层的物性特征,弄清储集层的岩性,物性,电性,含油性的关系,取得计算储量,编制开发方案的各项参数等。由于其真实全面,虽然成本高,相对时间长,但仍然是最重要的不可缺少的录井项目。 “Core Logging ” refers to the process of obtaining various data by drilling down the rock column to the ground during drilling and using special tools to analyze and study it. The removed rock column is called “core”. Core is the most intuitive and most complete and comprehensive reflection of rock characteristics of the first data. By analyzing and studying the core, the sedimentary environment and reservoir distribution can be inferred according to lithology and lithofacies characteristics, and the characters of crude oil and biogenic oil, the physical property of the reservoir and the characteristics of reservoir Lithology, physical properties, electrical properties, the relationship between oil content, access to the calculation of reserves, the development of the program parameters and so on. Due to its real and comprehensiveness, it is still the most important and indispensable mud logging project despite its high cost and relatively long time.
