The reservoirs of Fei 3 interval of Feixianguan Group and Changxin Group in the folded belt east Sichuan has a strong heterogeneity,higher gas production and rich resources. In order to further appraise the heterogeneous reservoir property and by studying the logging and mud logging characteristic parameters of the area,the authors put forward the concept of gas bearing index and explored the quantitative prediction method for initially stabilizing productivity for the area gas zone and set up the corresponding appraisal model,and predicted the gas zone' s productivity in Fei 3 horizontal interval of Well JP 12 which is newly drilled at Jiannan structure rock column synclinorium in the folded belt east Sichuan,it was verified by the gas testing that the application in Well JP 12 was successful.

China deploys its oil exploration and development so widely that the safety risk from quality gets higher,contradictions caused by fast growth looms larger,and quality control becomes more difficult.Therefore,how to take special advantages of ideological and political work of state-owned petroleum enterprise and how to improve business quality management are the new issues for its quality controllers to explore.This paper presents broadly relations between business quality control and ideological and political work,analyzes the current dilemma the management is facing and puts forth the management idea in line with innovative ideological and political work.

Reservoir groups 1～3 on the lower segment of Jianxin-Tuoshi Xingouzui Formation in the east of Qianjiang depression Jianghan basin had all developed into tight sandstone lithologic trap with low porosity and low permeability.With the proceeding of exploration work in recent years,a batch of light oil reservoirs had been discovered in this area.Based on the study on the stratigraphic sequence and the characteristics of assemblage of source,reservoir,and capping rocks in Jianxin-Tuoshi district,this essay had made the most use of various shaft data obtained from geological survey,gas logging,well logging,oil testing and other techniques to draw up a comprehensive review of the reservoir features in the area and discuss the adoption of quantifying methods to assess the reservoir capacity.
