摘要： 根据川西坳陷中段侏罗—白垩系(浅、中层)和须家河组(深层)勘探程度的不同,选用了油田规模序列法计算侏罗—白垩系天然气资源量,容积法计算须家河组天然气资源量。结果表明,川西坳陷中段陆相层系天然气成藏地质条件优越,天然气资源丰富,其资源量达1.161 ×1012m3. 目前资源探明程度仅为14.68%,总体上处在天然气勘探早期快速发展阶段,资源潜力大。这将为今后天然气勘探部署和编制中长期发展目标提供地质依据。

Abstract: According to the different exploration levels of J-K (shallow and middle strata)and Xujiahe formation(deep strata)in the middle part of West Sichuan depression, the pool size sequence method is selected to calculate the amount of natural gas resources of J-K, reservoir volume method to calculate the amount of natural gas resources of Xujiahe formation. The results show that natural gas geological conditions in this area are preferable and rich in natural gas resources, with the amount of natural gas resources in place of about 1.161×1012m3. At present, the resources proven degree is only 14.68%, revealing that it is in the early fast development stage for gas exploration as a whole, with huge gas resources potentials. This will be as a guide for further gas exploration deployment and the midand long-term development goal establishment.

Key words: West Sichuan depression, natural gas resources, pool size sequence method, reservoir volume method
