非常规综合物化探方法寻找油气藏基础理论研究中的几个问题

评述了非常规综合物化探方法寻找油气藏领域的研究现状 .认为多年来这一领域中以应用为主的生产性科学研究项目过多强调短期行为 ,缺乏深入、系统与综合的基础理论研究 ,给方法技术的应用带来了较大的盲目性 ,制约了这一领域科学研究的发展及应用 .指出应该开展这一领域多学科的、综合的及系统的基础理论研究 .目前这一领域中值得深入研究的几个主要问题是 :油气地球化学场与地球物理场的形成机理、与烃类蚀变作用相关的岩石学与矿物学分析及与油气运移相关的岩石物理学研究等

SEVERAL ISSUES ON BASIC THEORY OF UNCONVENTIONAL COMPREHENSIVE GEOPHYSICAL AND GEOCHEMICAL EXPLORATION METHODS FOR LOCATION OF PETROLEUM AND GAS RESERVOIRS

The present state of the research into the unconventional comprehensive geophysical and geochemical exploration methods for the location of oil/gas reservoirs is reviewed. The authors conclude that the production and scientific research projects in this field for the past several years center around the application aspect. In this sense, all these projects focus more on the short_term benefits and therefore are short of deep, systematic and comprehensive basic theory research, bringing about relatively large blindness in the application of the research method and technology and restraining the further development and application of the scientific research in this field. The authors suggest that the multi_disciplinary, comprehensive and systematic basic theory research should be made in this field. The following issues in the hydrocarbon migration need to be further studied: (1) the mechanism for the formation of the reservoir geochemical and geophysical fields associated with hydrocarbon microseepage, (2) the petrology and mineralogical analysis associated with hydrocarbon alteration and (3) the petrophysics associated with reservoir migration.
