| 摘 要： | 基于壁心、分析化验、测井曲线等资料,对XX21-3油田馆陶组储层岩性特征、孔隙特征和物性特征等储层特征进行分析,结合区域沉积背景认为馆陶组储层为辫状河心滩沉积,水动力条件的不同是导致N1gⅢ上和N1gⅢ下2个亚油组具有不同物性特征的原因,为后期优选开发层位提供依据。M油田与XX21-3油田相邻,是已开发经验较为成熟的油田,且与XX21-3油田在构造、沉积、储层和原油性质等方面具有相似性。为了规避XX21-3油田在储量评价过程中的风险,挖掘潜力,通过类比和借鉴邻近M油田,认为:1XX21-3油田馆陶组块状底水稠油油藏在不考虑油水界面起伏的理想模式下确定的含油面积存在风险;2N1gⅢ上油组探明油底下推到最大圈闭线计算的控制储量潜力很大。

| Abstract: | With the data from sidewall coring, laboratory analysis, logging, and reservoir lithology, pore features and physical properties were researched for the XX21-3 oilfield for the purpose to optimize development layers. Combined with regional sedimentary background, it is considered that the Guantao Formation is a sort of channel bar deposits of a braided river, and the variation in hydrodynamic pattern accounts for the different physical properties of the upper and the lower N1 g Ⅲ Formation. The M oilfield is a developed oilfield next to the XX21-3. It has accumulated with rich experiences and is similar to the XX21-3 oilfield in tectonics, deposition, reservoir and crude oil properties. Following the experiences from M oilfield, risks of reserves evaluation and potentials of further production of the XX21-3 oilfield are carefully studied. It is concluded that big risks may occur if there is no consideration of fluctuation of the oil-water contact, and there is great potential to increase the controlled reserves of the upper N1 gⅢ Formation. |
