运用含氮化合物咔唑类探讨塔中、塔北地区在第一期成藏时志留系油气藏的烃类的运移方向 ,为建立古油藏成藏模式 ,预测原生油气藏分布提供依据 .研究表明 ,塔中志留系古油藏的油气主要来源于满加尔凹陷的中、下寒武统烃源岩 ,向西南—南的方向首先进入塔中志留系 ,然后沿不整合面或顺储层从北西向南东和从北东向南西 2个方向向志留系在塔中地区的尖灭线附近运移 .塔北志留系古油藏的油气也主要来自满加尔凹陷的中、下寒武统烃源岩 ,首先向北西方向进入塔北隆起的志留系 ,然后在志留系储层内或不整合面沿上倾方向继续向北西方向运移进入圈闭
Carbazoles, a nitrogenous compound, were used to investigate the hydrocarbon migration direction of the Silurian reservoirs during the first accumulation in the Tarim Basin and Tarim Basin. It provides evidence for the establishment of paleo-oil reservoir accumulation patterns and the prediction of the distribution of primary oil-gas reservoirs The research shows that the oil and gas of the ancient reservoirs in the Tazhong Silurian mainly originated from Meso - Lower Cambrian source rocks in the Manjial Sag, and first entered the Tazhong Silurian in the direction of southwest - south and then moved along the unconformity Orshun reservoirs migrate from Silurian to Southeastern and from northeast to southwest in two directions towards the Silurian near the pinch line in Tazhong area.The oil and gas in the ancient reservoirs in the Silurian of Tarim Basin also mainly come from Manjar sag Of the Lower Cambrian source rocks, first into the Silurian uplift of the Silurian in the northwesterly direction, and then continue to migrate into the northwest direction within the Silurian reservoir either unconformity along the updip direction into the trap
