In the process of sediment, the sedimentary system is generally accumulated by multi-sources or mutative sources. In the establishment of a geologic model, the use of a single source can not meet the accuracy requirement. Taking some oversea large-scale deep-water subsea fan, A oilfield, as an example, the two reservoir stochastic simulation methods, the segment method and the trend-line method, are proposed based on the facts that a high-sinuosity deep water turbidite channel is developed widely and the flowline changes from time to time. The segment method is to divide the high-sinuosity deep water turbidite channel according to the geology knowledge and simulate the process separately and independently; the trend-line method is to set a quantitative geologic trend line and simulate the process as an entirety. The segment method applies to different sources and two non-cross sedimentary systems, while the trend-line method applies to the high-sinuosity deep water turbidite channel modeling under the same sedimentary system. Both methods are used to simulate the reservoir distribution of multi-sources or mutative sources in the same grid system, and the results show the spatial distribution characteristics of the high-sinuosity deep water turbidite channel.
