Comparison and Implications of Typical Normal Pressure Shale Gas Development between China and the United States
摘要
Abstract
To address the issues of low single-well production capacity,immature engineering technology,and diffi-culty in development profitability of China's normal pressure shale gas,and to explore reasonable development ap-proaches,taking Fayetteville Shale Gas Field in the United States and Dongsheng Shale Gas Block in China as ex-amples,based on the geological characteristics of the two gas fields,the evaluation and comparison are conducted in terms of favorable area evaluation,single well productivity and engineering costs.The study shows that the evaluation of favorable areas for shale gas in Dongsheng Block is comparable to Fayetteville,but Dongsheng Block is still in the early stages of development,with greater burial depth and more complex geological conditions.It is necessary to combine the characteristics of later development,learn from the experience of Fayetteville,and further refine and deepen the zoning classification evaluation.The modes of Fayetteville and Dongsheng Shale Gas Field are partition compound development.The supporting engineering technology is gradually improved.For all that,the intensity of block fracturing fluid and sanding in Dongsheng are lower than those in Fayetteville,resulting in a lower average sin-gle well EUR.Continuous studied is needed.Both Fayetteville Gas Field and Dongsheng Block adhere to the goal of continuous cost reduction.The comprehensive cost per well keeps decreasing,but further efforts are required in Dongsheng Block,aiming to lower the comprehensive cost per well to within 3 000×104 to 3 500× 104 yuan.The geo-logical resources of normal pressure shale gas in China are abundant,which is the main source for enhancing re-serves and production.By further clarifying favorable areas,tackling supporting engineering technologies,reducing o-verall costs,the comprehensive benefit development will be realized,which is of great strategic significance for the long-term stable production of shale gas in China.关键词
