鄂尔多斯盆地华庆地区长63储层综合评价.pdfVIP

最后，综合考虑储层岩石学特征、物性特征和孔隙结构参数等指标，采用以 物性和孔隙结构为核心的综合分类方案，对华庆地区长63 油层砂岩储层进行分 类，划分出了三个类别的储层。然后，结合储层分类结果、沉积相和砂体展布特 征以及试采特征，预测出该区两类有利建产目标区共五个预测有利区块。 关键词：鄂尔多斯盆地 层序地层学 物源 沉积相 砂体展布 II The Chang 6 reservoir bed comprehensive evaluation in 3 Huaqing area of odors basin Introduction of the author: Wang Lijing, female, was born in September, 1982 whose tutor was Professor Lu Zhengyuan . She graduated from Chengdu University of Technology in oil/gas development geology major and was granted the Master Degree in June, 2010. Abstract Ordos Basin, Hua Qing area is located in center of the YanChang lake, sediment is extremely complex, the reservoir heterogeneity is strong, relatively high permeability reservoir quickly to changes in vertical and horizontal segment, single well production decline rapidly, high concentration block more difficult to implement, scale capacity building development difficult. Therefore, the Chang 6 reservoir evaluation is of great significance. The Chang 6 reservoir is low permeability, low permeability reservoir of reservoir characteristics and flow compared to conventional reservoirs laws vary considerably, so the evaluation of the Chang 6 is particularly important to find out oil rich region. Chang 63 reservoir bed is one of the major reservoir in Huaqing area of Odors Basin. In order to achieve oilfield producing energy construction much more quickly, to select favorable producing energy construction target, it is of very necessity and importance to study on comprehensive evaluation of Chang 6 reservoir bed. 3 Firstly, take sedimentary environment of Chang 63 reservoir bed into consideration, combine both sedimentary markers with Sequence strat
