Key technique and its application of fault interpretation by well-seismic data for complex fault block of Hailar-Tamtsag Oilfield
摘要
Abstract
In high water-cut development stage of Hailar-Tamtsag Oilfield,remaining oil potential tapping in fault-controlled block requires high-accuracy fault characterization.Production wells confirm that fault identification and characterization accuracy in initial stage cannot meet the demand.In order to solve the aboved problems,starting from research on seismic interpretative processing,multi-attributes fusion and fault interpretation ideas,spectral in-version interpretative processing technique is developed to improve fault imaging quality of low dominant frequency seismic.HIS(Hue-Intensity-Saturation)fusion attribute technique is innovated to improve identification capability for fault zones and small faults.A well-seismic integrated fault interpretation method guided by staged interpretation idea is established,which solves"cutting axis"problem of multi-staged faults intersecting parts and finely charac-terizes fault plane geometry.The results show that application of the aboved technique can effectively identify faults with displacement of≥10 m and deepen the understanding of fault systems in complex fault block.The achieve-ments of fault re-recognition are applied in non-producing remaining oil potential tapping in Block 19 of Tamtsag Ba-sin.15 wells are deployed,with increased reserves of 4.32×106 t.The research provides important technical support for potential tapping of overall faults-controlled area in Hailar-Tamtsag Oilfield.关键词
