摘要
分别运用体积法和地质建模法对页岩F区吸附气地质储量和游离气地质储量进行计算,进而求得总地质储量,然后分别运用类比法和公式法对页岩F区采收率进行预测,进而求得该区可采储量,最后根据行业标准对页岩F区储量进行评价。结果表明:页岩F区地质储量约为235.867亿m3,采收率约为40.73%,可采储量约为96.067亿m3,为低孔特低渗高有机碳含量中深层低丰度中型页岩气田,所得结论对该区的认识和开发具有重要意义。
The adsorbed gas geological reserves and the free gas geological reserves of shale zone F were calculated by using volume method and geological modeling method, respectively.And then total geological reserves were calculated. Afterwards, the recovery of shale zone F was predicted by using analogy method and formula method, respectively. And then the recoverable reserves were calculated. Finally, the reserves of shale zone F were evaluated according to the industry standard. The results show that the geological reserves of shale zone F is about 23.5867 billion cubic meters, recovery is about 40.73%, recoverable reserves is about 9.6067 billion cubic meters. This zone is a low porosity, ultra-low permeability, high content of organic carbon, medium-deep, low abundance and medium-sized shale gas field. The conclusion is of great significance to realization and development of this zone.
