摘要： 由于碳酸盐岩储集层的强烈非均质性,碳酸盐岩储集层研究一直是一个世界性的难题。随着地震采集技术的.发展和地震属性技术研究的不断深入,使利用地震属性研究碳酸盐岩储集层成为可能。以塔中16井区为例,利用“视储集空间”构成及储集层岩石物理相的新观点,在地震属性分析基础上,充分利用地震、地质、测井及测试信息,用神经模糊综合评价方法,对研究区裂缝分布、储集层“视储集空间”进行了定量分析及预测,指出了最有利的储集区、裂缝发育区。实现了碳酸盐岩储集层“视储集空间”构成的定量化,并对其进行了质量评价。

Abstract: Because of the strong heterogeneities of carbonate reservoir, the research about it has become a worldwide hard task for a long time. Recently, with the technical development in seismic acquisition and seismic attribute, it is possible to research carbonate reservoir with seismic attribute. Taking Well Block Tazhong-6 as an sample, the author quantitatively predict the fractures and “Visual reservoir space”distribution in this area, with new theory of Visual reservoir space and “reservoir petrophysical facies”, using new method of fuzzy neural comprehensive estimation. Finally, the most favorable reservoir and fracture-developed areas are pointed out, with the quantitative determination of “Visual reservoir space” of carbonate reservoir and the evaluation of its quality.

Key words: central Tarim basin, carbonate rock, reservoir rock, fuzzy math, neural network, petrophysics, fracture, quantitative analysis
