摘    要:
中国石油集团碳酸盐岩储层重点实验室经过近10年的建设和发展,初步形成了岩石组分与结构分析、储层地球化学实验分析、孔隙形成与分布模拟实验、储层地质建模和基于储层地质模型的地震储层预测5项技术系列,为碳酸盐岩沉积储层研究提供了一站式解决方案。本文重点阐述了岩石组分与结构分析和储层地球化学实验分析2项技术系列的技术内涵、技术进展及应用。岩石组分与结构分析主要从不同角度开展岩石结构和矿物成分分析,是碳酸盐岩沉积储层研究最基础的工作,为深化沉积储层认识提供了手段。储层地球化学实验分析主要包括同位素和元素地球化学检测,在碳酸盐岩储层成因与分布规律研究中得到广泛的应用,其中碳酸盐矿物激光原位U-Pb同位素定年、团簇同位素、激光原位碳氧稳定同位素在线取样测定和微量-稀土元素激光面扫描成像等技术是近几年开发的核心技术,也体现了储层地球化学实验分析技术从全岩溶液法到激光原位法再到激光面扫描成像的技术发展趋势。

Abstract:
After nearly ten years of construction and development, the CNPC Key Laboratory of Carbonate Reservoir has preliminarily developed five technical series, including rock composition & structure analysis, reservoir geochemical experiment, pore formation and distribution simulation, reservoir geological modeling and seismic reservoir prediction based on reservoir geological model, which offers a one-stop solution for carbonate sedimentary & reservoir research. This paper focuses on the technical connotation, technical progress and application of two technical series of rock composition & structure analysis and reservoir geochemical experiment. The analysis of rock composition & structure is the most basic work of carbonate sedimentary & reservoir and provides a means for further study of sedimentary & reservoir. The reservoir geochemical experiment mainly includes isotope and element geochemical detection, which has been widely applied in the research of carbonate reservoir genesis and distribution. The laser-ablation U-Pb isotopic dating, carbonate clumped isotope analysis, laser carbon and oxygen isotope online analysis and laser trace-rare earth element mapping are the core techniques of the reservoir geochemical experiment developed in recent years, reflecting technical development trend from whole rock to in-site to mapping in reservoir geochemistry.
Keywords: rock composition and structure; reservoir geochemistry; laser-ablation U-Pb dating; cluster isotope; experimental technology; carbonate
