Fine 3D Seismic Interpretation And Reservoir Prediction In Fuyu Oil Layer Of Honggangbei

The Fuyu oil layer of Hongangbei is low porosity and low permeability reservoir.in 2012 Essentially realized that Fuyu reservoir depends on horizontal wells to generate oil through horizontal wells development experiment at Hong90-1 area.However,there are some problems unhandled,such as low horizontal wells sandstone drilling-encounter ratio,large variation of reservoir between wells and hard to control the horizontal wells path.It is necessary to carry out horizontal wells`elaborately 3-D seismic interpretation and reservoir prediction to guide deploy horizontal wells in 2013 for increase oil reservoir drilling-encounter ratio,decrease investment of the productive construction.This paper use elaborately layer comparison,seismic interpretation and reservoir prediction to conduct sandstone prediction. Combining with sedimentary facies model, elaborately research of distributary channel in delta plain of North Fuyu reservoir and elaborately describe distribution of sandstone.Combining with sedimentary facies model analyze the influence factors of horizontal well drilling-encounter ratio, and carry out horizontal well guidance to provides the geological basis for horizontal well deployment and adjustment.Horizontal well technology has been rapid development in recent years, but the trajectory of horizontal well geosteering is always a difficulty, the relevant literature is also deficient. This project is in the process of study according to previous experience and combining with the characteristics of local region invent a mothod of horizontal well drilling tracking.Combinied with seismic data,well logs and reservoir prediction,effectively guide the adjustment of horizontal wells trajectory and improve the sandstone drilling-encounter ratio of horizontal wells.
