Evaluation Of Volcanic Rock Reservoir In No.1 Section Of Xu Shen 1-2

As a very complex complex reservoir,volcanic reservoir has a wide range of lateral distribution,complex lithology,lithofacies and reservoir space,and has a good potential for natural gas exploration.It is the main area of deep gas exploration in Daqing oilfield in the future.Based on the theory of gas reservoir description,petroleum geology,oil and gas field development geology,reservoir geology,and so on,the geological background and stratigraphic division are clearly constructed on the basis of geological data,logging data and dynamic data collection,and the study of rock core,logging,single well lithology identification and multi well lithology comparison Based on that,we studied the distribution characteristics of various volcanic rocks.The Xushen 1-2 well studied in this paper is the development and evaluation well of the core of the whole well section of the long well section of the Xujiaweizi area.This study is mainly based on the characteristics of the lithology,lithofacies,pore structure and diagenesis of the volcanic rock,and the reservoir evaluation and oil and gas water will be evaluated in a comprehensive way..It is of great significance for the understanding of the first section of the volcanic rocks in Xingcheng and the understanding of the regularity of the geological change between the craters.It can lay the foundation for the design of the future gas field development plan and the development of natural gas.
