Control of Slope Breaks of Karagansky Formation on Sand Bodies in Baojingen Graben, Kazakhstan

Development of slope break in western slope of Baojingen Graben, Kazakhstan. In order to summarize the mechanism and model in slope break of Karagansky Formation. According to the characteristics of the seismic section and the genetic mechanism of slope break, the slope break of Karagansky Formation can be classified as fault slope break and flexure slope break, the plane is divided into high slope break, middle slope break and low slope break. And some understand has been made.The fault slope break is considered to be the main type in this area. The influence on distribution of the sand body in lateral and vertical is mainly reflected in which includes the role of macro-control, the sand body deposition guiding function, the local sand body enrichment and the sand body genesis. The middle break is the main distribution area of the sand body of Karagansky Formation. Based on the analysis of the control effect of slope break on sand body, three kinds of sand-body control models are established, such as the break control mode, the groove control mode and the slope step mode. The above sand control modes have certain guidance and reference significance for studying the sand body distribution rule of the same type of garden slope.
