The gas flow field in hydrocyclone separator was numerically simulated by applying RSM turbulence model, and the gas flow velocity distribution and stress distribution were calculated. According to the characteristics of gas flow distribution within the separator, it is found that: (1) the rotating strength of gas flow is related to the outlet angle of guide blade, the greater the outlet angle, the smaller the tangential velocity; (2) the obvious short circuit flow distribution under the exhaust pipe mouth area is easy to carry droplets and roll them out, causing a decrease in separation efficiency; (3) the high strength of turbulence pulse at mouth area of vent and drainage is easy to break the droplets and decrease their diameter, which affects the separation efficiency. The above research results lay the foundation for the structure optimization and the improvement of separation properties of axial guide vane cyclone gas-liquid separator.

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.
