Application of Development Seismic to Infill Technique in Oilfield of Small Size of Sand Body

摘要

This paper proposes a new approach to infill and adjustmentrnusing 3D high-resolution development seismic in blocksrnwhich have a complicated structure, smaller sand body andrndiscrete distribution. A detailed description of this structurernwas interpreted by a full 3D interpretation after effectivernacquisition of data (bin 10*20m, sampling rate 1ms).rnReversion, including wave impedance, laterolog 3 resistivity,rnspontaneous and natural gamma was done by the applicationrnof a thin interbed seismic inversion method. By integratingrngeological information, logging and production testing, as wellrnas production behavior data, the distribution of the sand bodiesrnwas clear and a potentially profitable area of remaining oilrnwas determined. Good results in infill and adjustment werernachieved and production in the area was improved.
