天赐湾地区长4+5、长6油层组原始含油饱和度计算方法研究
摘要
Abstract
In order to further identify the crude oil geological reserves of Chang 4+5 and Chang 6 reservoirs in Tianciwan area of Ordos Basin,a systematic calculation method of original oil saturation was carried out.According to the characteristics of low hole and ultra-low permeability of Chang 4+5 and Chang 6 reservoirs in Tianciwan area,closed coring analysis method,mercury injection method(J function)and logging interpretation method(Archie formula)are used to calculate the original oil saturation.The results show that the average original oil saturation of Chang 4+5 and Chang 6 reservoirs in the study area measured by closed coring method is 46.7%.The average original oil saturation of Chang 4+5 and Chang 6 formations measured by mercury injection(J function)is 47.5%.The average original oil saturation of Chang 4+5 formation and Chang 6 formation is 51.4%and 48.7%,respectively,according to well logging interpretation(Archie formula).The average original oil saturation measured by the three methods has little deviation,which can provide important data support for the calculation of crude oil geological reserves of Chang 4+5 and Chang 6 reservoirs in the study area.关键词
