Benefit Evaluation Of Unconventional Gas Field Development In Sichuan Basin

Under the circumstances of rapid development market economy,making full use of limited resources to maximize the development benefit and enhance the competitiveness of enterprises is each oilfield enterprise goal and core work.In the future unconventional oil and gas resources will be the key point of the development of the oil and gas industry,its market role will become more and more prominent and become a important supplement to conventional oil and gas resources.In order to ease energy supply and demand contradiction in China,in the future there will be a exploration and development of unconventional oil and gas resource on a large scale.Sichuan basin is rich in unconventional gas resources,its particularity decided to adopt advanced technology and stimulation to get considerable development benefits.It is a topic worthy of thinking deeply that how to rational development and application of unconventional gas field in Sichuan province.This paper get the unconventional gas field in Sichuan basin as the research object,with unconventional nature gas development knowledge and benefit evaluation theory as the theoretical basis,the author has began the study of unconventional gas field in Sichuan basin on the basis of a large number of reference related literature domestic and overseas.At first,the author has analyzed the development present situation of unconventional gas field in Sichuan basin,including Sichuan basin natural gas resource profile,the basic features and the development present situation three aspects.At second,finding out the influencing factors of unconventional gas field development benefit,mainly includes resource factors,technical factors,cost factor,market factor and policy factor in five aspects.Thirdly,the author has established a set of benefit evaluation model on unconventional gas field,from the principle of selecting evaluation index,evaluation index system of design,the choice of evaluation method,the determination of index weight and the choice of indicators to measure five aspects.Finally,choosing a field as the evaluation object to calculate and analyzing the evaluation results,we can reference the successful experience of the unconventional gas field.
