随着油田的不断勘探与开发,厚油层的储量已经得到了广泛动用,致密储层、小层等渗透率低的油层逐渐成为油田开采的主力,也逐渐成为研究人员主要的科研公关方向。渗透率低的薄差储层,由于其岩性、岩相变化大,成岩作用复杂等地质特征,导致勘探开发难度比较大。本文根据本人实际工作经验,主要分析了鄂尔多斯盆地下石盒子油层储层特征及形成机理,以求更加准确的了解下石盒子油层的剩余油分别情况,为地质录井、储层预测及储层评价提供可靠依据。
With the continuous exploration and development of oilfield, reserves of thick oil reservoirs have been widely used. Reservoirs with low permeability such as tight reservoirs and small reservoirs have gradually become the main force in oilfield exploration and have gradually become the researchers’ major PR directions. Thin reservoirs with low permeability and low permeability have great difficulty in exploration and development because of their geological characteristics such as lithology, facies change and complex diagenesis. Based on my actual working experience, this paper mainly analyzes the reservoir characteristics and formation mechanism of the Lower Shihezi oil reservoir in the Ordos Basin in order to get a more accurate understanding of the remaining oil conditions in the Lower Shihezi oil reservoir. It is of great significance for geological logging, reservoir prediction and reservoir Evaluation provides a reliable basis.
