摘要

Taking the pluvial fan sedimentary strata of Kexia Formation in San No. 3 ＋ 4 Block of Karamay oilfield as an example, with the help of the combined analyses among cores, well logs and seismic data, four base-level cycles, one long-term cycle, two medium-term cycles, four short-term cycles and many extra short-term cycles are classified. Under the control of the base-level cycles, the methods of the key surface constraint-correction and stream-cutting, filling and contrasting for event sedimentation are introduced to solve the problem of the lack of short-term interfaces, and then the complete sequence stratigraphic framework is established. Thus the prediction of the spread laws of the reservoir sandbodies can be carried out.
