It is necessary that the developers take advantage of the opportunity to make further efforts to promote shale gas development in China, in particular by rolling out a comprehensive plan on a national level. The author makes a proposal to establish a special shale gas test area in and adjacent to the Sichuan Basin as the most important way to promote the rapid development of shale gas in China. For this purpose, the author analyzes the current situation and problems of shale gas development in China, addresses the necessity and feasibility of establishing a special test area for shale gas development, and draws up the scope of this shale gas special test area of about 450 thousand square kilometers, covering Sichuan, Chongqing, Guizhou, and part of Yunnan, Hunan, Hubei provinces, and proposes the establishment of a shale gas test area in China. This consists of an overall plan, targets, and contents in 10 aspects, along with organization and implementation modes. The shale gas exploration and development in the shale gas zones is promoted vigorously by introducing special policies and innovating exploration, development and utilization model. While at the same time, the shale gas zones of continental facies in the Ordos Basin and marineterrigenous facies in South Hubei Basin will be established.The experiences of the reform in the shale gas zones will be the good practice for the reform of petroleum organization system.展开更多
页岩含气量是页岩含气性评价和有利区域优选的关键性参数，对页岩气资源评价和储量预测具有重要的意义。通过两种实验方法分别测定鄂尔多斯盆地中东部上古生界二叠系山西组页岩含气量，并对两种方法的准确性做了对比和讨论。解析法测定...页岩含气量是页岩含气性评价和有利区域优选的关键性参数，对页岩气资源评价和储量预测具有重要的意义。通过两种实验方法分别测定鄂尔多斯盆地中东部上古生界二叠系山西组页岩含气量，并对两种方法的准确性做了对比和讨论。解析法测定页岩含气量测量直接，数据直观，对取样要求高，测出的页岩含气量更接近真实值。等温吸附实验法取样快速简便，但受实验条件所限，需通过数学模型拟合计算含气量数值，误差较大，适合用于不同岩性和层位的页岩吸附气量的相对比较。通过实验，初步确定鄂尔多斯盆地上古生界山西组页岩含气量为0.82~1.25 m3/ t 岩石之间，0.82 m3/ t 岩石较接近真实值。展开更多
