The Application Of Reservoir Prediction Technique In Fuyu Reservoir Of The Central Depression In Jilin Oil Field

Seismic reservoir prediction is carried out based on the high resolution seismic data and logging data, with geological data and well drilling data for reference, wave impedance inversion and the selection and application of attribute parameters are the key of reservoir prediction technology.Reservoir prediction is the key technology in oil and gas exploration and development. We researched the reservoir seismic comprehend sive prediction technology with seismic method in this paper. Reservoir prediction research content mainly to ascertain reservoir tectonic characteristics, lithology and reservoir characteristics parameters so as to reduce the risk of exploration and development. Reservoir characteristic parameters including porosity permeability, fluid type etc. Whileseismicdata provide amplitude information parameters of seismic wave travel time, and then the elastic parameters by inversion. Seismic rock physics is to build a bridge between the elastic parameters and reservoir parameters.In the central depression area of fuyu oil layer is given priority to with large river deposition, channel sand body development, sand ratio between 30%- 70%, single sand layer thickness on the 3 m to 10 m, mudstone interlayer in the range 1 m to 20 m thickness, sandstone superimposed relationship is complex. Dense reservoir development, but most of the reservoir development, strong heterogeneity, well part of single well oil production capacity is not high.The main content of this study is the key blocks in the exploration and deployment, in view of fuyu oil layer dense oil reservoir prediction of the difficulty, to carry out the fine seismic data interpretation and reservoir prediction technology research and application.This study analyze the geological and reservoir characteristics of Fuyu Reservoir, and then using a variety of methods to try reservoir prediction, compare the results of multiple applications in many wells, summed up a suitable central depression area of Jilin Oilfield Fuyu Reservoir reservoir prediction method,for the deployment of the horizontal well with precise reservoir top surface structure interpretation and reservoir prediction results.
