摘　　要：琼东南盆地ST区块SY组完钻两口探井,测录井资料均显示储层岩性异常复杂,岩性种类多(十几种),因此,对该区块的岩性和物性进行精细划分,并根据岩心实验数据按岩性分类建立孔隙度-渗透度关系,在测井解释中加以应用,提高测井渗透率的计算精度。Two exploratory wells have been drilled in SY formation of ST block in Qiongdongnan Basin,The logging data show that the reservoir lithology is abnormally complex and there are many types of lithology(more than ten kinds).In this study,the lithology and physical properties of the block are finely divided,according to the core experimental data,the porosity permeability relationship is established according to the lithology classification,and it is applied in logging interpretation,the accuracy of permeability calculation is improved.
