本文通过对孔隙介质中热源传热的数学物理方程分析,并结合沙桶中热源传热物理试验,发现在对储层加热过程中,油气层中点热源处的温度与水层(或干层)中点热源处的温度相比增温的速度明显地快,而在加热过程后,油气层中点热源处的温度与水层(或干层)中点热源处的温度相比降低的慢。据此提出用人工热源(炸药热源、电热源等)对地层进行加热,然后测量井中温度的动态变化,据此思想,提出了一种从孔隙介质传热出发解释油气层、预测油气产能的传热测井新方法。
Based on the mathematical and physical equation of heat transfer in porous media and physical experiment of heat source heat transfer in sand bucket, it is found that during the process of reservoir heating, the temperature at point heat source in reservoir is different from that of water layer ) The temperature at the midpoint heat source is significantly faster than warming, and after the heating process, the temperature at the point heat source in the reservoir decreases more slowly than the temperature at the midpoint heat source of the water layer (or dry layer) . Therefore, it is proposed to heat the formation with artificial heat source (explosive heat source, electric heat source, etc.) and then measure the dynamic change of temperature in the well. According to this idea, a new method of heat transfer from porous media to explain the formation of oil and gas, New method of thermal logging.
