摘要
辽东湾地区东营组地层岩性偏细,具砂泥过渡岩性的特征.本文通过对泥质岩的标定,确定以碎屑粒径小于0.05mm为泥质岩标准,进行测井岩性剖面的数字处理;并以岩心资料为基础,研制了一套泥质含量及粒度中值的计算方法.利用这两项成果进一步研究了它们与最小含油喉道半径的关系,提出利用粒度中值计算渗透率的公式及确定包括这两项参数在内的储层参数,并在地层的划分对比,相分析工作中取得效果.
In Liaodong Bay,Dongying formation is primarily fine gr-aind and of transitional lithology.This study defines shale thatits grain size is less than 0.05 mm in order to conduct digitalprocessing of lithologies of log curves.On the basis of cores,inaddition,formulas to calculate shale content and intermediategranularity have been established.Furthermore,relationship ofthese 2 parameters with minimum oil-bearing throat radius wasstudied.As a resultant,a formula was proposed to compute pe-rmeability with intermediate grain size.Besides,the author be-lieves that these 2 parameters could be used to predict otherlithological parameters and help make stratigraphic division andfacies analysis.
