Abstract:

The reservoir in the eighth member of lower Shihezi Formation in Sulig Gas Field is typical braid river sedimentary system. Drilling wells in 3D multiwave multicomponent work area in northern Sulig Gas Field are little. Based on the well data and the analysis of the palaeogeomorphology, the sedimentary facies were studied with applying the analysis techniques of Stratimagic seismic facies, seismic multi - attribute and relative wave impedance. The result showed that the whole work area is braid river sedimentary system which develops braided channel and flood plain deposit microfacies, and that the provenance come from northern work area where there are three main channels in NS direction, and several distributary channels developed. The development of the western main channels is the biggest, and the western channels show obvious convergence.

Key words: creative thought, fixed thought, imagination, intuition, attention, side-direction thought, thought of seeking difference
