Shale Gas Reservoir Interpretation And AVO Forward Modeling

China continues to progress,the world is also constantly in development,in a variety of technologies continue to improve the situation,the resource problem has always been we must face the most important,the current conventional energy oil,but a single energy can not meet people's Demand,but also in the oil mining,the use of the process will produce a lot of pollution,and now the subject of environmental protection out of tune.Natural gas has always been a representative of conventional energy,but also a new type of energy,but this conventional energy content is small,and can not become the mainstream of China's energy,so shale gas and some unconventional energy more and more get attention.With the United States shale gas development made a major breakthrough,countries began to follow suit,looking for their own country's natural gas resources.According to incomplete statistics,China's shale gas content is quite amazing,if reasonable and effective development,will certainly be able to make outstanding contributions to China's energy industry.However,China's shale gas industry is still in the initial stage,the method of technology is still learning,groping,I believe that through continuous efforts,will be able to achieve a breakthrough,standing in the forefront of the world.This paper begins with the mechanism of shale gas accumulation,expounds the basic concepts and forming conditions of shale gas,and then introduces our current evaluation conditions for shale gas reservoirs.As a result of the interpretation of the practice of interpretation in the exploration of the experience,then talked about the interpretation of three-dimensional seismic data,through the synthesis of seismic records for horizon calibration,and then through the seismic coherence technology and other fine calibration,and fine structure,and then according to the actual work area The physical model of the rock is established to find the petrophysical parameters with the highest correlation with the target geological body.Finally,the AVO forward modeling of the shale gas is obtained by the left Briz equation,and the AVO response of the shalegas is obtained,and the effect of AVO is analyzed according to the conditions that affect the AVO factors.Finally,according to the actual work area data obtained in the internship unit,the prediction of the shale gas reservoir content in the target area is obtained,and the result is credible.
