摘要
松辽盆地十屋断陷存在两类地表化探异常带 :一类为油气沿嫩末运动形成或复活的断裂运移至地表所致 ,具有物上气仍然活跃的特点 ;另一类为油气通过微渗漏所形成 ,具有ΔC、酸解烃及物上气高异常的特点。桑树台断裂和双龙构造上方的地表化探异常带为第一类成因 ;
Therer are two kinds of geochemical anomaly zones in Shiwu faulted depression.One was resulted from oil gas migration along the faults formed or reactivated in the end of Nenjiang movement.The free gas in this kind of anomaly zones is still active.The other kind was formed of oil gas micro seepage.This kind of anomaly zones have high abnormal ΔC and acid degradated hydrocarbon.The geochemical anomaly zones of Sangshutai fracture and Shuanglong sturcture belong to the first kind;that of Houwujiahu and Siwujiazi Gasfields belong to the second kind.
