Abstract

Jason stochastic seismic invention method of simulated anneal is applied in developing oilfield blocks,improved reservoir description precision and oil-gas identification.In order to understand the spatial changes of Xing'anling group reservoir in Suderte oilfield Bei14 block, according to seismic,logging and geological information,applies the stochastic seismic invertion method of simulated anneal on Bei14 block, illustrates the distribution and spatial morphology of major reservoirs,occurring as overlapped sandstones vertically,multi-stages in plan,and NE sources.On invention section the ribbon-like or lenticular sandstones are vertical or inclined to source orientation,while on invention section with progradation configuration parallel to source orientation.This method is useful to understand the reservoir character during late development period and allocate boreholes. Application of invertion in reservoir prediction has been a important method and technology in international Petroleum Industry,the basic purpose of invertion is to use the propagation law of seismic wave in underground medium,through such processes like the data acquisition,processing and interpretation,speculate the space distribution of underground rock and physical parameters,these data can provide an important basis for the exploration and development.The recursive invertion of the first generation is suitable for the early stage of exploration,the vertical resolution of recursive invertion is slightly higher than that of the conventional seismic profile,however,more effective seismic information loss so that not enough to identify and divide effective reservoirs; The recursive invertion and constrained sparse spike of the second generation is under well logging control,mainly refers to the model based,this recursive invertion is under well logging constraint, suitable for the late stage of exploration of relatively less well logging data, the vertical resolution of recursive invertion can reach 10m.Invertion is limited to seismic wave impedance data or the quasi wave impedance data with special information derived from the acoustic impedance of the reconstructed log,more effective seismic information loss so that can not enough to be directly got other logging curves by invertion,can not carry out fuither reservoir physical property prediction research,either,the accuracy is not enough to solve these problems; The logging interpolation and extrapolation and Depth domain physical propertyinvertion of the third generation is under seismic control,is a seismic constrained log invertion under the condition of enough well logging data,in this invertion core algorithm,genetic algorithm,artificial neural network,chaos algorithm,simulated annealing and other advanced theories are integrated[1-2],the Seismic inversion technique is main based on well log data,more useful information preservation,so that the vertical resolution were improveed an order of magnitude-can reach meter le
