Application of Fractures Prediction Technology in Carbonate Rock Reservoirs

Abstract:

Prediction of fracture is the current difficulties in reservoir prediction, According to the difficulty of carbonate fracture prediction is even greater. Especially when the study area is in slope of buried hill, the main purpose of deeply buried layer (5000-6500m), small structural deformation, major faults are not developed, minor faults are not obvious, weathering and corrosion weak cases, bring the difficulty and challenge to the fracture prediction technology based on tectonic origin. In this paper, view of the above geological conditions, application of the coherent, fine fault interpretation, AVA and MVE fracture prediction technique. At the macro level, the coherent time slice and fine fault interpretation to determine fracture as the constraint of MVE 3D geological modeling, Determine the orientation of fracture by using AVA prediction and FMI imaging logging methods, the tectonic evolution, studying tectonic movement of different period effect on fracture and oil and gas, according to the prediction of fractures and fracture connectivity analysis, forecasting fracture favorable area, and achieved good results.
