The Research On The Structure Modeling Technology By Integrating The Well And Seismic Data In Gaotaizi Oilfield

Because of the insufficient in understanding of the structures of Gaotaizi Oil Field, which against oil field development, it is necessary to carry out the research of tectonic modeling technology based on the integrated information of well and seismic data. This work has been done from several aspects, and has obtained some helpful knowledge.Being aimed at that the SP curve affected by water flooded layer, its baseline in these layers usually appear migration and the shape of step, or even the whole curve slide, exploring the correction method of the SP curve baseline drift. Being aimed at the inconformity dimensional phenomena caused by the different times or instrument or series of logging, the normalization and standardization processing be used to the SP curve and acoustic travel-time curves. Because of some wells has no density curves, through the correlation analysis of the curve, using the correlative curve, adopt predicting method to reconstruct the density curves; Based on the principle which ’seismic data control the configuration and well information confirm the exact composition’, the recognition of fault and breakpoint homing combination in Gaotaizi oil field have been finished; With the comprehensive utilization of the fault from seismic interpretation and the materials of well breakpoints and horizon data and seismic attributes to assemble the space of fault from the dot, line, face and style, the occurrence of faults is confirm at the same time. The model of fault in Gaotaizi oil field is completed, the characteristics of fault was summarized, and the recognition of fault was appraised impersonality. Through the contrastive analysis of the previous knowledge to prove that the fault from tectonic model based on the integrated information of well and seismic data is more reliable. Through the validation of reductive wells, structure modeling algorithm was optimized. On the basis of the establish of fault modeling, combining the seismic interpretation horizon and well tops data, the tectonic model of oil field was finished, and the characters of structure in research area was summarized, and the accuracy of tectonic model was validated. Overall, research area from Yang I to Nen II structure has good inheritance.Through the research, the normalized three-dimensional tectonic modeling process and method have been explored and formed, which was used in oil field development, and achieved good results, and become the basis of deepen research.
