Research On The Sedimentary Microfacies Characteristics Of Binxian Wangfu Area Chengshen 2 Borefild Quansanduan Formation

The article based research on Chengshen 2 borefild Quansanduan formation,multipurpose using the rule and means of sedimentary petrography, reservoir geology,petroleum geology, seismogeology, adopting great quantity log data, core data, doghouse dope,seismic data, systematic researching and describing the interest interval precipitation and the characteristic of physical property, analyzing the type of sedimentary microfacies, the rule of gas/water distribution, the characteristic of sand body distribution, finally comprehensive evaluating beneficial save phase belt of every sand.First of all, applying the theory of seismology and applied sedimentology, uniting predecessors’ findings, and the data of wells, proceeding formation and dividing comparison this area, the thickness of the formations alternated evenly, most of the formations are uniform thickness, dividing 5 sands, 15 members. And then using the lithology and logging information of the core phase,phase and log phase to distinguish the sub-facies types in this study area,futher more subdivide microfacies.On the basis of properties,sand,earthquakes,and other information,drawing sedimentary facies, analysising the sedimentary characteristics of this area.The river course’s sands are the most beneficial reservoir sand in this research.Summarize the sedimentary evolution under the sedimentary facies papers.And research the relationship between the sedimentary facies and reservoir stratum,it provid important basis for forecasting the favorable reservoir facise of Quansanduan.
