The Accurate Gas Pool Description Of The Reservoir Of The Carboniferous System In Leiyingpu Structural Belt Of East Sichuan

The paper is guided by the theory of sedimentology,reservoir geology,earthquake geology, develop geology and the latest gas reservoir description theories from domestic and international. The main studied objects are the information of drilling, logging, earthquake and the dynamic develop data of the gas reservoir. With multi-subjects, multi-techniques synthesis methods and advanced analysis techniques, it is carried out detailed description to the sedimentary facies, structures,characteristics, faultage characteristics,crack characteristics, reservoir characteristic, stratum pressure system, fluid property and gas-water connection of Leiyingpu structural belt in Sichuan basin.Using lasted 2D seismic analysis data and drilling data of studied area,it has new understanding and sets the development and distribution characteristics of structure and faultage,and analysis the structure and faultage influence on gas-water distribution.Taking structure distribution and reservoir as studied focus,accurate explain structure,optimum analysis studied clue,it gives accurate gas reservoir geology distribution study to realize gas turn-in stratagem in this area.Theory analysis on Lei Yin Pu structure belt,it believes that Lei Yin Pu has the higher gas reservoir production degree and higher discovery degree,but not disequalization,and Cha Yuan Shi production degree is high,but discovery degree is low,and Ting Zi Pu has the higher gas reservoir production degree and higher discovery degree.
