沙113井区油藏描述研究
|
摘要
通过地层对比、地震解释、构造研究、沉积相等方面对克拉玛依油田沙113井区进行油藏精细描述的研究,采用"旋回对比、标志层控制、厚度约束"的方法将目的层进行划分至6个大层、20个小层,并通过"井震结合"方法解释出20条断层,通过测井资料解释出平均油层厚度为6.7 m,叠合含油面积7.65 km2,并运用单砂层储量叠加法对储量进行了计算,将储量计算细分到单砂体,最终估算出地质储量482.7×104t,为搞清区块剩余油分布特征和滚动开发提供了依据。
Based on stratigraphic correlation,seismic interpretation,tectonic research and sedimentary facies,this paper does a re search on fine reservoir description of Sha-113 well field of Karamay oilfield.By the means of‘cycle comparison,marked layer control and thickness restriction’,this paper divided the target layer into 6 big layers and 20 small layers.This paper interpreted 20 fault layers by using‘well-seismic combination’method and interpreted that average layer thickness is 6.7 m and overlapped oil-bearing area is 7.65 km2 by using logging data.By using reserve superposition method of single sand layer and subdividing re serve calculation into single sand body,this paper estimated that geological reserves are 4,827,000 t.The results provided referenc es for exploration of residual oil distribution features and rolling development of the area.
