Located in the central part of C hangyuan,Daqing,the trend of the apricot structure is relatively gentle.Most of them are NNW and NW trending faults.In the early stage of the Qingshankou Formation reverse cycle and the early Yaojia composite cycle,the reservoir was deposited in this layer,the sedimentary facies,the delta facies,the delta facies as sedimentary facies,from the vertical aspect,with the interaction characteristics of sand mudstone and the existence of different multistage cycles.In Daqing oilfield,the North apricot area of Songliao basin is the key oil producing area,and the main oil producing section is mainly Fuyu and Saertu oil layers.The main stage is high development in the two or three time.The high Taizi reservoir,especially the third member of the upper Tertiary,is still in the initial stage of exploration because of its complicated traps and complicated reservoir forming conditions.This study mainly focuses on the theoretical analysis of the sedimentary,structural and reservoir characteristics of the high third formation,summarizes the formation rules of the high three groups,and determines its dominant reservoir,providing the technical support for the subsequent development of the high three formations.This study mainly uses the combination of well earthquakes as a means,and through the study of the tectonic evolution characteristics and sedimentary background chara cteristics of reservoirs,the history of tectonic evolution has been restored,and the study of the combined drilling,logging and seismic strata in the whole region has been carried out.Point-line-surface-space has been practiced and understood many time s,and various methods such as coherent bodies have been used to assist in the study.The structural error has reached 1.87 ‰.By selecting 5 lines to study the growth index,it is found that the strong fracture deformation period of the block is Q ingshankou Formation,Yaojiazu,Nen,and Nen,and a total of 3 sets of fracture systems are developed.By studying the high three groups of sedimentary systems in Xingbei O ilfield,two types of "river controlled fan-shaped main sand" and "wave controlled mat sand" were established,and it was determined that the area was a large-scale shallow lake basin Delta sedimentary system with the source in the North and Northwest.Two main,Finally,2 sub-phases and 6 microphases were divided;In the sand body prediction,the wave impedance inversion is used as the background,and the idea of combining well earthquakes is used to carry out the co-simulation random inversion,relying on the reconstructed...
