Prediction methods of lithological reservoirs in Yuanyanggou area and effectiveness analysis

Analysis of the petroleum geology in Yuanyanggou area of Western sag shows that,the area is favorable in forming lithological reservoirs,and understanding of reservoir distribution is the key to reservoir prediction.Techniques of seismic attribute,3-D log constraining inversion and hydrocarbon detection have been used to identify and predict reservoir.The successful drilling of Well Jin 310 substantiates that these techniques are useful in practical exploration.
