长垣油田地震层位准确拾取与小断层识别
ACCURATE PICKUP OF THE SEISMIC HORIZONS AND MINOR FAULT IDENTIFICATION IN PLACANTICLINE OILFIELDS
摘要
Abstract
In residual oil tapping study, the accurate interpretation of the reflecting horizons and recognition of the minor faults with about 5 m slip are the problems of the seismic technique. In South and North Blocks of Lamadian Oilfield, the interpretation problem of the seismic horizons in the size of developing individual layer by following high-precision horizon-picking techniques mainly composed of data frequency division and horizon flattening; the minor faults are determined by the reflecting amplitude and wave form changes; the inter-well spacial spread of the faults is made sure by the seismic coherence. The facts show that the faults with over 3 m slip can be recognized by the seismic data and the intepreted faults can guide the tapping study of the residual oil and the arrangement of the developing well location.关键词
