Abstract

Abstract: Porosity evolution of reservoirs is a key and difficult point of the study on hydrocarbon accumulation mechanism.But the present research methods of "porosity inversion and back stripping" have some flaws,including equating thin section porosity with porosity,attributing the porosity loss by compaction to early diagenetic stage,and neglecting rock bulk volume's reduction in the compacting process.In this study,compaction was corrected in every stage of diage-nesis according to the normal compaction curve.Equation of porosity variation through history is derived,accounting for the porosity loss through compaction and cementation,and also porosity increase by corrosion,also taking into account of rock bulk volume variation in every stage of diagenesis.A case study on Chang 7 and Chang 6³ tight oil reservoir of the southwest Ordos Basin was carried out,integrating the diagenetic facies of the research area and the derived formula.We reconstructed the porosity evolution from inversion and back stripping under the constraint of diagenetic sequences,and built five porosity evolution pattern and porosity evolution curve by different methods.If compaction is not corrected and rock bulk volume change is not considered,large error of the recovered porosity exist and it may be up to 13.8%.

Key words: rock bulk volume, diagenetic facies, porosity evolution, tight sandstone reservoir, Yanchang Formation, Ordos Basin
