页岩气储量计算结果是制定页岩气开发方案,确定页岩气产业投资规模,并对页岩气资源进行评估的重要依据。页岩气藏独特的吸附解吸机理决定了其储量计算过程有别于常规气藏。以页岩I区块为例,采用体积法对该区块的页岩气地质储量进行计算。体积法是计算页岩气储量的基本方法,应用范围广,可适用于各个级别的页岩气储量计算。体积法计算的精度取决于对储层和气藏地质条件的认识和控制程度,以及所获取参数的数量和精度。研究结果表明,体积法计算储量的结果为2.4809×10~(10)m~3,为页岩气田开发提供了依据。
The calculation results of shale gas reserves are an important basis for formulating shale gas development plans, determining the scale of shale gas industry investment, and assessing shale gas resources. The unique adsorption and desorption mechanism of shale gas reservoirs distinguishes its reserves from conventional gas reservoirs. Taking shale I block as an example, the volumetric method is used to calculate the shale gas geological reserves of the block. Volumetric method is the basic method for calculating shale gas reserves. It has a wide range of applications and can be applied to the calculation of shale gas reserves at all levels. The accuracy of the volumetric method depends on the understanding and control of the geological conditions of the reservoirs and gas reservoirs, as well as the quantity and accuracy of the acquired parameters. The results show that the calculated volume of volumetric method is 2.4809 × 10 ~ (10) m ~ 3, which provides the basis for the development of shale gas field.
