APPLICATION OF THE SLOPE-BREAK THEORY TO SUBTLE TRAP EXPLORATION OF WUDONG SLOPE IN HAILAER BASIN

For Wudong Slope of Hailaer Basin, the research on systematic characteristics is very poor. However, the research on the slope-break theory illustrates that there are three kinds including structural, depositional and erosional slope break in the slope according to the genetic type, occurrence change and combination style of the slope break. In addition, many series of laterally widely distributed and vertically superimposed fan body, which develop along the slope, have been found by means of reservoir prediction research. These researches consider that the structural slope break of rift lacustrine basin has an important effect on the formation and distribution of subtle traps.
