港北潜山上古生界碎屑岩储集层岩性评价技术
|
摘要
港北潜山石炭-二叠系地层煤、碳酸盐岩、砂岩等岩性交互发育,且多为过渡岩性,有效的岩性识别直接制约物性和含油性的评价,如何有效评价港北潜山岩性是测录井综合评价需要解决的重要问题之一。针对港北潜山上古生界复杂储集层岩性特征开展研究,形成了一套测井、录井资料相结合,适合港北潜山上古生界碎屑岩储集层的岩性评价技术,提高了潜山复杂储集层的岩性识别能力,为储集层有效性及含油性的评价奠定了基础,为油田增储上产提供了技术保障。
Coal,carbonate rock and sandstone of CarboniferousPermian strata in Gangbei buried hill are interbedded,and most of them are transitional lithology.Effective lithology identification directly restricts the evaluation of physical properties and oil-bearing properties.How to effectively evaluate the lithology of Gangbei buried hill is one of the important problems to be solved in comprehensive evaluation of well logging and mud logging.In this paper,a set of lithology evaluation techniques suitable for the Upper Paleozoic clastic reservoirs in Gangbei buried hill has been developed by combining well logging and mud logging data with the study on the lithologic characteristics of the complex reservoirs in the Upper Paleozoic in Gangbei buried hill.The lithology identification ability of complex reservoir in buried hill is improved.The technique lays a solid foundation for the evaluation of reservoir effectiveness and oil-bearing property,solves the technical problems of complex reservoir evaluation in multilayer buried hill exploration,and provides technical guarantee for increasing reserves and production of the oilfield.
