东营凹陷古近系红层砂体有效储层的物性下限及控制因素
Petrophysical parameter cutoff and controlling factors of effective reservoir of red beds sandbodies of Paleogene in Dongying depression
摘要
Abstract
Based on oil production test, mercury injection data and physical properties, the petrophysical parameter cutoff of effective reservoir of red beds sandbodies of the first member of Kongdian formation ( Kk,) and the lower submember of the fourth member of Shahejie formation(Es4χ) of Paleogene in Dongying depression was determined by distribution function curve method, oil production test method, and irreducible water saturation method. Combining the analysis of sedimentary characteristics, diagen-esis characteristics and reservoir pressure characteristics of red beds sandbodies, the controlling factors of effective reservoirs were discussed. The results show that there is the function relation between the petrophysical parameter cutoff of effective reservoir and depth. Sedimentation is the main controlling factor while diagenesis is an important factor that affected effective reservoir development in red beds sandbodiee. Itie influence of rocks color and reservoir pressure on reservoir physical properties is not obvious. The effective reservoir was mainly developed in the underwater distributary channel and mouth bar of shallow water delta and flooded lake delta, the sheet deposit and braided channel of alluvial fan, and in the bar main body of lakeshore beach-bar.关键词
