摘　　要：对塔里木盆地奥陶系碳酸盐岩储层研究发现,虽然同为孔洞型碳酸盐岩储层,并且从测井计算孔隙度来看都能达到工业产能,但是结合试油资料来看,储层有效性却差别很大。研究认为,孔洞型储层有效性与孔隙度及孔洞类型有关,且大孔孔洞型储层较小孔孔洞型储层有效。根据测井资料,结合试油资料,可以判断孔洞型储层有效性。By studying on carbonate reservoir in Ordovician system in Tarim basin,it is shown that efficacy of reservoir is more difference if it is combined with well test data although all of them are carbonate reservoir with cavern,and can get commercial productivity according to porosity getting from well logging.Research shows that effectiveness of reservoir with cavern relates to porosity and the type of cavern,and reservoir with big cavern is more effective than with little one.According to well logging data,and combining with product test data,effectiveness of reservoir with cavern can be decided.
