Technology Research On Reservoir Prediction For Neogene Shawan Formation For N1s2 In Chepaizi Oil Field

Seismic exploration technology has become an effective mean about the search for oil and gas resources with the development of petroleum exploration field,and it can solve more and more geological problems with the continuous development of all kinds of science and technology.There is abundant reservoir property information in seismic data,so the reservoir prediction technology is particularly important in the field of oil and gas exploration.Now the seismic exploration is becoming more and more difficult,so we need start to carry out a lot of research work in the reservoir geological characteristics of regular and special reservoirs and seismic attribute and the applicability of the reservoir prediction technique in order to get more reliable and clear formation physical parameters and increase the precision of seismic interpretation and reduce the uncertainty,and it has obtained certain research results,and it plays a positive role in guiding the subsequent oil and gas exploration and exploitation.This paper is mainly an elaborate reservoir prediction for Neogene Shawan formation for N1s2 in Chepaizi oil field,and is mainly to solve various problems and deficiency of reservoir prediction in N1s2.We analyze the existing wells and reservoir and seismic sections,and obtain the three factors of reservoir forming of this area according to the combination of basic data for the seismic,logging and core logging.Respectively,most of reservoir distribute along the shoreline,and the highlights and non-bright spots of accumulation both have lens features and they match with fracture.This research can be divided into three parts by the three factors of reservoir forming.First of all,we can carry out the structural pattern of the research area by fine seismic structural interpretation.Then we can have a good identification to beach bar sand-body trap by the attribute technology and the layer flattening means.Finally,we can carry out beach bar sand-body trap of favorable area by seismic attribute technology and the flat profile features.Combining the above methods,we can get a well reservoir prediction result,and these researches bring the actual production efficiency for N1s2 in Chepaizi oil field.
