录井技术的发展,使油气层解释评价的手段日益增多,但不同录井方法的原理和对象不同,可能造成油气层解释结论的不一致,因此需要对录井资料进行综合解释评价。高邮凹陷地质构造复杂,油藏类型丰富,储层特征各异。通过研究高邮凹陷油、气、水层在常规地质录井过程中的表现特征,并结合岩石热解、定量荧光、岩样核磁分析等录井新技术的解释结论,对油气显示层进行综合分析,判断储层性质,以克服现代工程技术对录井勘探找油、找气带来的不利影响,力求解决复杂岩性、特殊油气藏的油气层的评价解释难题,提升录井资料综合解释评价水平。研究中发现,由于高邮凹陷断层发育,构造破碎,不同区块油气水层特征差异较大,同一区块也可能有新的含油层系发现,因此在运用新的技术手段时,也要创新地层对比、气测三角形图版法等传统方法,不漏失任何油气层。
The development of mud logging technology makes the means of interpretation and evaluation more and more widely. However, the different logging principles and objects may lead to the inconsistency of interpretation results of oil and gas reservoirs. Therefore, it is necessary to make a comprehensive interpretation evaluation of mud logging data. The geological structure of the Gaoyou sag is complex with rich reservoir types and different reservoir characteristics. By studying the characteristics of oil, gas and water layers in conventional geological logging in the Gaoyou sag, combined with the interpretation results of new logging technologies such as pyrolysis of rocks, quantitative fluorescence and magnetic anisotropy of rock samples, a comprehensive analysis of hydrocarbon display layers To judge the nature of the reservoir so as to overcome the adverse effects brought by the modern engineering technology on the oil exploration and gas finding in the well logging exploration so as to solve the problems of evaluation and explanation of the complex lithology and special oil and gas reservoirs and to improve the comprehensive interpretation and evaluation of logging data Level. The study found that due to the fault development and tectonic crushing of the Gaoyou sag, the characteristics of oil and gas aquifers in different blocks are quite different, and new oil-bearing strata may also be found in the same block. Therefore, when applying new technical means, In contrast, conventional methods such as triangulation and gas measurement do not miss any hydrocarbon layer.
