The Application of Sand Sculpting Technology in Triassic Stratum of Lunnan Oilfield 206 Well Field

The Triassic stratum in Lunnan Oilfield 206 well field is located in the alluvial fan - Braided River Delta - lacustrine depositional system. The reservoir horizontal change is big; sand body physical properties and connectivity is poor; thickness change is big; identification is difficult. According to these characteristics, apply the analysis of Triassic sand sedimentary facies study high seismic data processing and multiple seismic attributes analysis to finish the sculpture of single sand body, which figures out the sand body lateral superposed relationship and distribution range and improves the accuracy of the prediction of sand body. The successful application of this technology shows the Lunnan Triassic oilfiled exploration potential, which has certain reference significance for the exploration and development of similar reservoirs.
