Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009 "Standardization Work Guide Part 1. Standard Structure and Compilation". This standard was proposed by the Ministry of Land and Resources of the People's Republic of China. This standard is under the jurisdiction of the National Land Resources Standardization Technical Committee (SAC/TC93). This standard was drafted. Oil and Gas Professional Office of the Mineral Resources Reserve Evaluation Center of the Ministry of Land and Resources, China National Petroleum Corporation Ltd., China Petroleum & Chemical Corporation, Shaanxi Yanchang Petroleum (Group) Co., Ltd. The main drafters of this standard. Chen Yongwu, Wang Shaobo, Han Zheng, Wang Yongxiang, Qi Longxiang, Yan Wen, Zhang Yanqing, Qiao Chunlei, Wang Xiangzeng, Guo Qijun, Zhang Junfeng, Bao Shujing, Liu Honglin, Hu Xiaochun. This standard is interpreted by the Ministry of Land and Resources of the People's Republic of China. Technical specification for calculation and evaluation of shale gas resources/reserves

1 Scope

This standard specifies the technical requirements for classification and definition of shale gas resources/reserves, calculation methods for reserves, and reserves evaluation. This standard applies to shale gas resources/reserves calculation, evaluation, resource exploration, development and design and report writing.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Shale gas shalegas Occurred in the organic-rich shale interval, the natural gas stored in the state of adsorbed gas, free gas and dissolved gas, which is self-generated A continuous gas reservoir that is stored in a reservoir; it is an unconventional natural gas that can be commercialized by volumetric fracturing. 3.2 Shale layer shalelayers The organic-rich source rock series is dominated by shale, mudstone and silty mudstone, with a small amount of interlayers such as sandstone, carbonate rock or siliceous rock. The tight sandstone gas or conventional natural gas in the interlayer is calculated according to the calculation formula of natural gas reserves. If the value of the separate mining is not achieved, Comprehensive exploration and mining of the associated minerals of shale gas. 3.3 Brittle minerals and content brittlemineralandcontent Brittle minerals in shale mainly refer to carbonate minerals and silicate minerals (quartz, feldspar and cuttings) in shale. Brittle mineral The content of the shale is related to the difficulty of the shale fracture transformation. To obtain better fracturing effect, the content of brittle minerals in the shale is large. At 30%.

4 General

4.1 The shale gas resource/reserve classification system adopts the GB/T 19492-2004 oil and gas classification system, and the classification framework is shown in Appendix B.
