松辽盆地深层天然气探明地质储量探明率低,不足总资源量的10%,具备较大的资源潜力。吉林探区近年来营城组火山岩以及沙河子组、火石岭组砂砾岩等勘探领域中获得了重要发现或者突破。但随着勘探进程的加快和勘探程度的不断提高,需要进一步寻找勘探接替新领域、寻求新突破。从成藏条件及勘探潜力分析来看,认为基岩有望成为下一个比较现实的勘探接替新领域,其中梨树断陷基岩钻遇井较多,多种成藏类型均获发现,是下步勘探的重点区带。
The proved provenance rate of deep natural gas in Songliao Basin is low, less than 10% of the total resources, with great potential for resources. In recent years, the Jilin Exploration Area has obtained important discoveries or breakthroughs in the Yingcheng Formation volcanic rocks, the Shahezi Formation and the Huoshiling Formation glutenite. However, with the acceleration of the exploration process and the continuous improvement of the exploration level, it is necessary to find further exploration and replace new areas and seek new breakthroughs. From the analysis of hydrocarbon accumulation conditions and exploration potential, it is considered that the bedrock is expected to be the next more realistic exploration succession. Among them, there are many wellbores encountered in the bedrock of the pear tree and many types of reservoirs were found, Step exploration of the key areas.
