Abstract
Debris flow which is not usually developed in marine deep-water places, was intricately and extensively developed in Xingma area, Liaohe Oil field in China. It is the mixture of compacted sandstone and conglomerate with no permeability. The debris flow and high density turbidity current (HDTC) (good reservoir) are difficult to be effectively differentiated by the conventional post-stack method, since both of them have strong reflection. Furthermore, decades of explorations show that pre-stack method is also not satisfying due to the poor seismic data in this area and the inaccuracy of conventional rock-physics model in this argilliferous sandstone reservoir. For a better HDTC reservoir prediction, an integrated pre-stack method including advanced data conditioning, rock-physics analysis using AS-Xu-White model and pre-stack inversion was elaborately designed and successfully applied in this area. It is an important complement to current knowledge for non-marine deep-water reservoir prediction.
