Dina 2 Gas Field High Resolution Logging Sedimentary Reservoir Description

Dina 2 gas field in Kuche Depression Qiulitage tectonic belt,proven geological reserves and control of gas is larger than 1000x108m3,condensate oil geological reserves of more than 800x104 t,in order to further mine development Dina 2 gas field,need careful study on Dina 2 gas field,how to improve the utilization rate of materials,how to improve the imaging logging interpretation accuracy,how to utilize the imaging logging reservoir fine description,become the emphasis and difficulty in the study.This research mainly uses the imaging logging data and conventional logging data and core data,using core calibration logging technology to improve imaging logging interpretation accuracy,through the establishment of interpretation chart library to improve the utilization rate of material,on the basis of the Dina 2 region imaging logging sedimentary reservoir description,the following results:(1)Formed a system of lithology,sedimentary structure and fracture characteristics and logging response characteristics of one-to-one logging interpretation charters;(2)Through the single well vertical lithologic facies analysis,it is concluded that Dina area fan delta and lake facies developed in Paleogene system,including fan delta is given priority to,the eastern region development lake facies developed in the western region;(3)Using of imaging logging section structure correction accurately pick up sedimentary method for Paleogene direction characteristics of angle,Paleogene direction is roughly North-East to South-West,the source in the study area is in the North-East;(4)Through the well analysis,complete the preparation of fine insulation interbed even well section,analysis of interlayer insulation interbed,insulation interbed in general as the southwest northeast thick thin;imaging logging reservoir fine description.Results can provide the information to the follow-up development foundation.
