摘要
本文提出了利用岩心分析、测井资料描述隔层的基本框架，总结了大庆油田隔层岩性、物性特征，确定隔层的渗透率上限为１×１０^（－３）μｍ~２。依据隔层的岩电关系，由测井资料直接获得组成隔层的不同主要岩性。结合沉积环境分析，以油层单砂层间隔层的自然连续体为单元做隔层平面图，并将组成隔层的不同岩性在图中反映出来，从而形象地反映出了不同环境下隔层的连续性、阻渗能力。本文同时分析了不同分布特征的隔层对加密调整的影响。
Based on cores analysis and logging data, this paper suggests a framework for barrier beds discription. The lithology and petrophysical properties of barrier beds were summarized, and a maximum permeability for them-1×10￣(-3)μm￣2 is assigned. Taking advantage of the relationship between barrier beds lithologies and their log response, different rocks which formed barrier beds were recognized on log curve. Combining with sedimentary environment analysis, distribution of barrier beds is described by taking the natural continuous body of barrier beds between two single-sand layers as a mapping unit, and different rocks identified from log curve are also shown. Thus, their continuity and fluid-resistance are realistically represented. And, their effects on oil field infilling and adjustment well drilling is demonstrated.
