Haft-graben fault basin often have large-scale gentle slope, and the zone of structural style, sedimentary types and forming factor has its unique characteristics. This paper takes Chenjiazhuang area in Jiyang depression for example. By constructing, deposition and accumulation of combining methods Chenjiazhuang area can be divided into three major tectonic units, witch are upliftt zone, slope zone and structural slope-break zone. Different tectonic units develop different sedimentary and reservoir types, and the accumulation controlling factors are also larger differences.
