Prediction And Evaluation Of Reservoir In Qi 2-13-312 Area

With the increasing level of exploration and the continuous extension of the exploration area, China's onshore oil and gas exploration has entered into a entered a new phase that oil and gas exploration phase of both, Find minor structural reservoirs, old liberated Rolling Extension and stratigraphic reservoirs become a major exploration targets. The area affected by two factors control the lithology and structure, lithologic reservoir development area mainly concentrated in the structure of the wing, furrow area, slope area. Therefore, identify characteristics of the geologic structure, lithology, geometry, physical parameters and hydrocarbon potential, to become the main task of reservoir prediction.In this paper, three-dimensional seismic data of poor quality in the area, Rapid lateral variation of reservoir, A large extent on regional tectonic interpretation accuracy constraints, Prediction of reservoir thin so difficult, the use of vertical seismic profile the speed of extraction of reliable parameters of layers were accurate calibration, which greatly improves the accuracy of seismic data processing and interpretation, to identify the tectonic evolution of the area. Use of constrained inversion method greatly improves the accuracy of reservoir inversion to predict the target area and spatial distribution of reservoir distribution. Use of synthetic VSP logging data and seismic records to establish log sequence and the relationship between seismic sequence analysis sedimentary environment, the establishment of sedimentary facies pattern, distribution of depositional systems derived features. After the construction of the entire work area, inversion, sedimentary reservoir draw such analysis, the three favorable reservoir development area, the final prediction with good results, traps have some oil reserves for the future provides the basis for the exploration work.
