热力作用下石油流体运移的能量方程

为了探讨油气运移成藏机制，从热力学角度论证了热可以作为油运移的动力，并根据模拟实验结果首次建立热力系条件下热作为流体运移动力时流体流动的能量方程，研究了流体在热力作用下焓的变化情况．在模拟实验中油运移的速度和距离取决于油(流体)从外界吸收的热量及焓．由此，有可能对热作为石油流体输运动力进行半定量一定量研究．同时，结合实际例子探讨了热力学系统中流体运动的热力学关系，认为热作为流体输运的动力在实际盆地中比较复杂．如果从单一因素(热)来考虑流体运移动力，则取决于热的大小和输导层的物性、产状等．

Energy Formula for Oil Migration in Thermodynamic System

This paper discusses that heat can act as the driven force of oil migration in the point of view of thermodynamics. The energy formula for oil migration, that heat acts as the driven force of fluid movement, was established in the thermodynamic system based on the experimental results. The variation of enthalpy in the fluid flow indicates that heat and its enthalpy control the migration velocity and distance of oil flow. The enthalpy decreases with the increase of migration distance. The paper also discusses the dynamics of oil movement in semi-quantitative to quantitatively. At the same time, thermodynamic relation of fluid flow within the thermodynamic system is applied to the practical carriers, the results indicate that heat regime taking as the driven force shows more complicated patterns in practical basins. The distance of oil migration depends on the amount of heat and physical characteristics of carriers.
