通过对深层天然气形成的地质条件的研究认为，松辽盆地北部深层由多个断陷组成，发育东部、中部、西部3个断陷带，东部断陷带徐家围子断陷地层厚度大、埋藏适中，是勘探重点；断陷期沙河子组湖相泥岩厚度大，分布范围广，生烃条件优越，是主要烃源岩；以基岩、火山岩和碎屑岩为储集层，在登娄库组二段与泉头组一段—二段区域盖层控制下发育上部、中部、下部3套生储盖组合，以中部组合为主；发育基岩风化壳、源储一体致密气、源内火山岩、古隆起带盖层4种成藏模式，营城组火山岩和沙河子组致密砂砾岩是主要含气层系。在地质条件分析基础上，采用成因法、类比法重新计算主要断陷、重点勘探层系资源量累计15 885.67×108m3。依据地质条件及剩余资源规模等因素，进一步明确了下步勘探层次及方向：在徐家围子断陷可通过“精细火山岩，加快致密气”扩大储量规模；在莺山—双城断馅、古中央隆起带加大甩开力度，扩大勘探成果；在林甸—古龙等断陷加强风险勘探，力争实现突破。
According to the geological conditions of the accumulation of deep gas，the northern Songliao Basin is composed of multiple fault depressions and three fault depression zones in eastern，central and western regions.In the east fault depression zone，the fault depression strata are of great thickness and moderate burial depth，which is the focus of exploration.The lacustrine mudstone of Shahezi Formation in fault depression period is the main source rocks with large thickness，wide distribution and favorable hydrocarbon generation conditions.With bedrocks，volcanic rocks and clastic rocks as reservoir，the three sets of reservoir caps (upper，middle and lower) are developed under the control of 2nd member of Denglouku Formation and 1st and 2nd members of Quantou Formation.The central combination is the dominant.It develops four kinds of accumulation models:Bedrock weathering shells，source storage integrated tight gas，source inner volcanic rock，and paleo-uplift belt cover layer.Volcanic rocks of Yingcheng Formation and tight grit rocks of Shahezi Formation are mainly gas-bearing systems.Based on the analyses of geological conditions，adopt genetic method and analogy method are used to recalculate the main fault depression and key exploration layers.The accumulative amount of resources is 1.59 trillion cubic meters.According to geological conditions and the scale of remaining resource，the next step exploration level and direction are further clarified.Among them，the “refining volcanic rock，accelerating tight gas” of Xujiaweizi fault depression is a practical field for the increase of reserve.To increase exploration degree and expand exploration scale in Yingshan-Shuangcheng fault depression and paleo-central uplift beltis an important replacement field.Strengthen risk exploration in Lindian-Gulong fault depression and strive for breakthrough.
