摘要
露头考察表明,很多横向分布稳定的砂体实际上是复合河道砂体,是由多条单河道砂体拼合叠置形成的。单河道砂体在储集物性方面的明显差异和隔夹层的存在,导致复合河道砂体含油不均匀。正确识别复合河道砂体中单个河道砂体的展布特征,可以更准确地建立储集层的地质模型,更好地进行剩余油挖潜。从露头、钻井和地震的角度,提出了判别单河道砂体的一些方法,即露头实测法、岩性对比法、电性对比法、厚度中心法、统计约束法、地震相及属性分析法。这些方法在寻找岩性油气藏中较经济、实用。
By outcrops studies,it is indicated that many laterally stable sand bodies are actually complex channel sand bodies formed by stacking of a number of single-channel sand bodies together.Single-channel sand bodies are much different in grain size,sorting,matrix content and barrier,etc.,resulting in uneven oil zone in the complex channel sand bodies.Understanding of the distribution characteristics of these single-channel sand bodies is helpful for establishing more accurate geological reservoir model and finding out more remaining oil.In this paper,on the basis of outcrop,drilling and seismic studies,some identification methods for single-channel sand bodies are proposed,such as outcrop measure method,lithology contrasting method,electrical contrasting method,thickness center method,statistical restraining method,seismic facies and attributes analysis method.These methods are economic and practicable for lithologic reservoir exploration.
