涪陵页岩气田油气资源管理探讨

On Oil and Gas Resources Management in Fuling Shale Gasfield

为了深化油气资源管理认识,助力涪陵页岩气田油气资源管理提升,在充分调研分析美国和加拿大等国外油气资源管理经验的基础上,依据涪陵页岩气田地质特征、资源储量及开发进展数据信息,探讨了优选区块层系分步实施、采用水平井分段压裂强化技术、统一精细规划水平段方位、创新“井工厂”模式提高建产效率、推行立体开发、提高采收率等系列技术策略,并进行了回顾性研究与评价,期望通过中国首个页岩气国家级示范区实践,实现对中国页岩气资源管理引领作用。

In order to deepen the understanding of oil and gas resources management and promote the oil and gas resource management in Fuling Shale gasfield,on the basis of thorough investigation and analysis of foreign oil and gas resources management experiences in the United States and Canada,in terms of the geological characteristics,resource reserves and development progress data of Fuling Shale gasfield,this paper discusses a series of technical strategies,such as step-by-step implementation of selected block strata,staged fracturing enhancement technology in horizontal wells,unified refined planning of horizontal section orientation,innovation of"multi-well pad"mode to improve production efficiency,three-dimensional development and enhanced oil recovery.In addition,a retrospective study was conducted in the hope that the practice of the first national shale gas demonstration area in China could play a leading role in the management of shale gas resources in China.
