Research and Application of gas reservoir modeling

In oil and gas field, we have little logging data in the early of exploration and development, but seismic data is abundance, which can be used to response to geological conditions roundly. For more accurate description of the reservoirs, this paper with the thought of combining seismic and well, making full use of different scales and extend of the seismic, logging, geological interpretation, and making variables statistics and variogram analysis with petrel software for building a three-dimensional geological model of reservoirs, which can be closer to the truth of underground geological. The model is under the control of sedimentary microfacies and reservoir properties, which provided the deployment for the gas reservoir development programs.
