摘要(Abstract)：

Duvernay地区是西加盆地页岩气开发的主要区块之一。同为海相页岩气,Duvernay与川南页岩气具有许多相似之处。通过对比分析,两者也具有一定的差异,主要体现在:川南页岩气沉积环境复杂,储层非均质性更强,对工程技术施工要求较高;川南多为山地和丘陵地貌,地面施工难度和成本较高,加上气候因素,春秋季节为产建施工最佳时期;由于国家激励政策、征地手续办理、安全环保等客观因素的差异,导致两者开发难点也不尽相同。综合学习Duvernay勘探开发经验,对川南及国内页岩气勘探开发提出了几点启示及建议:成熟的非常规油气项目决策程序是Duvernay页岩气成功开发的基础,建议重视页岩气前期勘探评价,尽早建立科学的勘探开发模板;技术进步是Duvernay实现效益开发的关键,建议加大技术创新力度,加快核心技术研发,尽快解决开发面临的技术难题;信息共享是Duvernay技术进步和效益开发的催化剂,建议优化完善信息平台,找准"共享"与"保密"的平衡点,充分发挥信息优势。
Duvernay area is one of the major shale gas development blocks in the Western Canada Basin. As marine shale gas, Duvernay shares many similarities with South Sichuan shale gas. Through comparative analysis, there are some differences between them, which are mainly reflected as follows: The sedimentary environment of South Sichuan shale gas is complex and the reservoir heterogeneity is strong, so the requirements are rather higher for the engineering technology and operation.In South Sichuan, the ground construction difficulty and cost are higher because of the mountains and hilly landform;coupled with the climate factors, the spring and autumn are the best periods for the productivity construction. Due to the differences in the national incentive policy, land acquisition procedures, safety and environmental protection and other objective factors, the development difficulties are not the same. Based on the comprehensive study on Duvernay's exploration and development experiences, several inspirations and suggestions were presented for the exploration and development of the shale gas in South Sichuan and China.The mature decision-making process for the unconventional oil and gas projects is the basis for the successful development of Duvernay shale gas, so it is suggested to attach importance to the early exploration and evaluation of the shale gas and establish the scientific exploration and development template as soon as possible; the technical progress is the key to the benefit development in Duvernay,thus it is suggested to strengthen the technological innovation, speed up the research and development of the core technologies, and solve the technical problems in the development as soon as possible; the information sharing is the catalyst for the Duvernay's technological progress and benefit development, consequently it is suggested to optimize and improve the information platform, find the balance between the share and secrecy accurately, and furthermore give full play to the advantages of the information.
