沉积盆地内热流体活动过程实际上是热流体聚集与散失的动平衡过程.热流体活动必然导致温度和压力以及化学条件的改变,尽管如此,沉积盆地内热流体活动的示踪难度较大.通过对莺歌海盆地典型实例的剖析,认为较为有效的方法就是通过热流体活动中的温度效应进行示踪研究.其中较为有效的参数有伊-蒙矿物的转换、镜质体反射率和有机物热解指标以及流体包裹体等.这些参数的不同形式的异常均指示了来自深部的热流体的活动.
The process of thermal fluid in the sedimentary basin is actually a dynamic equilibrium process of the accumulation and dissipation of thermal fluid. Thermal fluid activity inevitably leads to changes in temperature and pressure as well as chemical conditions, however, and the tracing of thermal fluid activity in sedimentary basins is more difficult. Through the analysis of the typical case of Yinggehai Basin, it is considered that a more effective method is to conduct the tracer study through the temperature effect in the thermal fluid activities. Among the more effective parameters are the transformation of Iraqi-Mongolia minerals, vitrinite reflectance and organic pyrolysis index and fluid inclusions. Different forms of anomalies of these parameters indicate the activity of the hot fluid from the deep.
