本文通过对H3Ⅰ-Ⅳ油组取芯井样品分析研究,弄清特高含水开发阶段储层孔隙结构特征、微观剩余油分布及水洗特征,为调整挖潜提供急需的微观技术资料.研究结果发现H3Ⅱ、H3III油组孔隙结构好于H3Ⅰ、H3Ⅳ油组;H3Ⅲ油组含油率较H3Ⅱ、H3Ⅳ油组高.岩石粒度偏细,含砾细砂岩、细砂岩为主的储层水洗较弱,剩余油含量丰富,是下一步挖潜的重点.

The cores samples are analyzed in this article to find out the microscopic remaining oil distribution,pore structure characteristics,and water features in later development of ultra-high water reservoir in H3I-Ⅳ oil group as well as microcosmic technical data for adjustment. The results show that H3II and H3III oil group have better pore structure that those in H3I,H3IV oil group;the oil-bearing rate of H3IIIis higher than that of H3II and H3Ⅳ. The reservoir composed of rock containing fine sandstone and fine sandstone features fine granularity and weak in watering,the residual oil content in it is rich,so it will be the focus of future exploration.
