The Way and Application of Fracture Pre-stack Prediction of Carbonate Rock Based on Azimuthal and Anistropic Travelling Time in Carbonate Rock Fractured Reservoir
摘要
The main reservoir types of Ordovician carbonate is fractured-vuggy reservoir. As one of the main controlling factor of integrated oil and gas rich reservoir, fracture is not only as a reservoir space, and it also plays an effective role of communicating and improving the effective storage of reservoir, and it is a prerequisite for high and stable production of oil and gas. There are many methods of seismic reservoir prediction for fractural reservoir, based on the characteristics of the propagation time of seismic wave in the fracture changing with the azimuth, we studied the methods of pre-stack fracture prediction based on P-wave pre-stack of azimuth trip time. The methods has been applied in Lungu17, and has gained significant effect.
