摘要
HF Oilfield is located in the southeastern part of Mesopotamia Plain.The target zone is deposited in Albian,Middle Cretaceous,which mainly develops a set of the interbeds of brown sandstone and dark brown-dark gray mudstone.The target zone is located in the development zone of fluvial dominated delta of marine and land transition.Depositional environment of predelta,delta front and delta plain developed.It is extremely important to use the logging data and seismic data to identify the depositional environment due to limited core data.The sedimentary microfacies types are confirmed through the use of reflection configuration,continuity,amplitude,frequency and geometry configuration.According to the change of vonformation and amplitude of logging curves(mainly using gamma ray and resistivity),the sedimentary microfacies of single well is divided after combined with the geological features such as lithology and rhyme.Some sedimentary microfacies,including tributary bay,underwater channel,mouth bar,far bar,are identified,in which underwater channel and sand bar are good reservoir environment.Based on the analysis of single well,crosswell sections are established through the comparison of logging curves in this paper,which knows the change features of sandy connectivity and physical property.Combined with seismic attribute,plane distribution features of sedimentary facies are analyzed,and favorable reservoir development zones are predicted,which provides a reference for later exploration and development.
