Study On Logging And Geology Response Characters Of Earth Interval ES4 Glutenite Reservoir In North Region Of Dongying

After several years'exploration and development, it has been highly mature exploration step in north area of Dongying, especially; lithologic hydrocarbon reservoir has been the main exploration direction. The area has good glutinite exploration foreground particularly in ES3 and ES4. It is difficult to classify single well reservoir phase and compare interwell formation and correctly cognize glutinite terrain sediment law and estimate reservoir. This paper defines the geology information character of the micro- resistivity imaging logging data and conventional logging data by collecting abundant primary information of drilling and well logging seismic and geology and by using the high definition advantage of micro- resistivity imaging logging data to calibrate conventional logging data.The logging services are very completely in this work area. Every survey is the combined action of rock composition, frame, sedimentary structure and fluid characters. All these elements have different affects for the surveys. So the logging information have different abilitys for the research of these events. In this paper, we demarcated the core and imagering information and using them to find out the different reaction characters of rock composition, frame, sedimentary structure and fluid characters.The logging information is one important information of oil and gas exploratory and development. It's the reflection of facies character and its facies character analysis are based on geologic analysis. It has definite geology meanings only through geology calibrating. The forth segment of ShaHeJie glutinite body are from Yan16 paleo-gulley and Yan18 paleo-gulley in northern zone eastern segment. The basement fracture forms are coulter fault and the slope gradient are high. These made the glutenite fan are widly development. By analysing, the forth segment of ShaHeJie glutenite body can divide into three positive rhythms from bottom to top. The main is offshore subsea apron sediment, and it can divide into three sediment intrafacies. We generalized the logging information characters of these sediment microfacies. The fan foot has high combination gamma ray neutron laterolog value and the SP has obviously high amplitude abnormality. The electric resistivity and tri-porosity curves have lesser fluctuate. The fan middle also have high GR value but less higher than the fan foot. The SP amplitude have major abnormality and regress to gamma ray shale line. Thin sand bed, plenty shale insulating layers made the electric resistivity and tri-porosity curves have violent changes and the fluctuate is mutability. The fan terminus is mainly shale and have thin sand between them. The SP value is gamma ray shale line value and low electric resistivity and GR regress to regime values.In this paper, we have compared multiwell sedimentary facies, analyzed the relationship of space throughgoing and development on sedimentary facies and glutenite body, predicted the extent width and length of fan body and compare with real geologic information. The process we apply in this paper offers beneficial gurrantee for the further instruction on exploration and development of glutenite body...
