子长油田热寺湾区长6油层有效厚度下限标准的确定

Determination of the Lower Limit Standard of the Effective Thickness of Chang6 Reservoir in Resiwan Area of Zichang Oilfield

本文根据据粒度分析资料、薄片资料、试油、试采、压汞数据等资料研究,对子长油田热寺湾区延长组长6油层有限厚度的下限标准岩性、物性、含油性及电性进行了确定。并按此标准对该区进行了解释,测井解释符合率很高,说明解释标准适合本区。该方法对今后勘探工作中的储量计算和评价具有十分重要的意义。

In this paper, according to the data research of grain size analysis, thin section data, oil test, production test and mercury injection data, lithology, physical properties, oil-bearing and electrical properties of the lower limit standard of effective thickness of Chang6 of Yanchang formation in Resiwan area of Zichang oilfield were determined. According to the standards, well log interpretation of this region was carried out. The coincidence rat of the logging interpretation was very high, so the standard is suitable for this area.
