摘要

摘要: 通过对比研究,按照岩性组合、气藏压力和页岩矿物组成3个关键参数,将美国典型页岩气藏划分为层状常压—低超压硅质页岩型(Barnett页岩)、层状超高压硅质—钙质页岩型(Haynesville页岩)和互层状超高压钙质页岩型(Eagle Ford页岩)3类。与美国页岩气藏相比,四川盆地及周缘页岩气具有多领域、多层系、多类型的特点,可划分为盆缘层状常压—低超压硅质页岩型(彭水、昭通五峰—龙马溪组页岩)、盆内层状超高压硅质页岩型(涪陵、长宁、富顺五峰—龙马溪组页岩)、盆内互层状超高压钙质—黏土质页岩型(涪陵、元坝大安寨段页岩)3大类。借鉴美国的成功经验,开展与之相适应的页岩气开发工程技术对策和经济评价,是实现中国多类型页岩气藏商业性开发的关键。

Abstract: Through the comparative studies on the geological parameters of typical shale gas reservoirs, according to lithologic combination, reservoir pressure and shale mineral composition, the typical shale gas reservoirs in USA are divided into three categories: the layered ordinary-overpressure siliceous shale type (taking Barnett as the representative), the layered super-high pressure siliceous-calcium shale type (taking Haynesville as the representative) and the interbedded super-high pressure calcium shale type (taking Eagle Ford as the representative). Compared to those in USA, the shale gas reservoirs in the Sichuan Basin and the surrounding area are featured by multiple fields, layers and types. They are also divided into three categories: layered ordinary-low overpressure siliceous shale type on basin margin (taking Pengshui and Zhaotong Wufeng-Longmaxi Formation shale as the representative), layered super-high pressure siliceous shale type inside basin (taking Fuling, Changning and Fushun Wufeng-Longmaxi Formation shale as the representative), interbedded super-high pressure calcium-clay shale type inside basin (taking Fuling and Yuanba Da'anzhai segment as the representative). Learned from the successful exploration and development experience of similar shale gas reservoirs in USA, targeting to carry out development and engineering technology research and economic evaluation of different type shale gas reservoirs, this is the key to realize the effective development of multiple type shale gas reservoirs in China.
