摘要： 本文利用测井资料对克拉玛依油田六—七区石炭系储集层的构造、岩性、裂缝、物性参数和油层标准研究后,作出判别凝灰岩、安山岩、安山岩—火山角砾岩、蚀变火山角砾岩—安山岩、砂砾岩的△GR—△NR和△t—△NR图版;利用26口井数字处理结果作出油层孔隙度图和油层厚度图,结合构造图和初产量成果图总结出该区的油气分布与不整合面深度的密切关系。二次解释结果各井油层共1783.9m,发现其中未射开的油层有1230m,为增产提供了依据。

Abstract: This paper proposes a study of structures,lithology,fracture,physical parameters and reservoir criteria for the carbOTiifcrous formations in the District No. 6 and No. 7,Karamay oilfields by using logging data,based on which —△NR and △t—△NR cross—plots are established for identifying tuff,andesite,andesite—volcanic breccia,altered volcanic breccia—andesite and sand—conglomerate. The close relationship between hydrocarbon distribution and unconformity depth in these districts can be obtained throgh porosity plots and thickness map of the payzone from digital processing data results of 26 wells associated with the structural map and initial production map. The results of secondary interpretation indicate that the reservoir thickness of all wells is 1783. 9m.among which 1230m oil pay unpcnctrated by perforation are found to be production potential.
