| 摘 要： | 通过钻井取芯分析测试、岩石薄片和扫描电镜观察手段,对徐家围子断陷营四段砾岩储层成岩作用特征进行研究。结果表明,徐家围子断陷营四段砾岩储层经历了强烈的压实压溶、胶结作用、复杂的交代作用和多期次的溶解作用。压实和胶结作用是降低储层物性的主要因素,溶解作用形成的次生孔隙是改善储层物性最重要的因素。根据砾岩中自生矿物的分布特征、黏土矿物的组合特征、镜质体反射率等资料分析,认为徐家围子断陷营四段砾岩成岩作用强烈,已经进入晚成岩作用阶段。

| Abstract: | Based on the measurements of drilling,coring,microscopic and microscanning,the diagenesis in the member 4 of yingcheng deep conglomerate formation in Xujiaweizi fault depression is researched.The results indicated that the member 4 of yingcheng deep conglomerate came through strong compaction,cementation,complex metasomatism and dissolution.Cementation is the main factor to decreasing porosity and permeability of reservoir while dissolution is the major reason of increasing porosity and permeability of rese... |
