摘要：

柴达木盆地跃进二号油田为典型的薄砂层多开发层系油田，垂向上含油层系多、目的层段长、单砂体薄，平面上砂体规模小、相带窄、相变快，不同层系、不同沉积环境的储层特征差别很大。以跃进二号油田N₂¹油藏为研究对象，分层系按沉积微相带建立了薄砂体多开发层系油田储层测井解释模型并进行了测井精细解释，从而提高了解释精度。在测井精细解释的综合化、定量化和自动一体化等方面进行了探索，研究了薄砂体多开发层系油田测井精细解释方法：测井资料预处理与标准化；测井计算泥质含量实现自动分层；测井沉积微相自动识别与划分；分层系按沉积微相带的储层参数解释模型；分层系按沉积微相带的测井精细解释。研究表明，分层系按沉积微相带进行测井解释是准确计算该类油田储层参数的有利途径。

Abstract:

The Yuejin-2 oilfield located in the Qaidam Basin is a typical thin-sand and multiple-developed-layer oilfield characterized by many vertical oil-bearing formations, thick intended intervals, thin single sand body, laterally small scale of sand body, narrow sedimentary facies with dramatic changes, and significantly different reservoir features of sedimentary environments. Taking the N₂¹ reservoir of the Yuejin-2 oilfield as a study object, fine log interpretation models was establised for thin-sand and multiple-developed-layer-system reservoirs according to microfacies zones of different bed systems, and a fine log interpretation was conducted with these models, which improved the interpretation accuracy ratio greatly. A certain progress in the integration, quantification and computer automation of fine log interpretation was made and some methods for fine log interpretation on thin sands and multiple-developed-layer systems were employed as well, which including as following:pre-processing and standardization of log data; automatic division of layers according to the shale content calculated with logging curves; automatic recognition and division of log facies; built up a fine log interpretation models based on sedimentary microfacies of different layer systems; and fine log interpretation according to microfacies of different layer systems. The results showed that it was a favorable way to accurately calculate the reservoir parameters by the log interpretation based on sedimentary microfacies of different lay system.

Key words: thin sand layer, multiple oil-bearing layer systems, detailed log interpretation, different layer system, sedimentary microfacies, Yuejin-2 oilfield
