研制出一种稠油油藏导热系数的测定仪，并介绍了测量方法。其测试原理是将一段铂丝夹在稠油井岩样中，铂丝加热后在不同介质中的温升速率不同，由此计算出介质的导热系数，由于硬件电路中采用了自动调零电路及计算机控制，使测试简单、快速、准确。现场应用表明，测试效果较为理想。 Developed a kind of heavy oil reservoir thermal conductivity measuring instrument, and introduced the measurement method. The test principle is to clamp a section of platinum wire in heavy oil well rock samples, platinum wire heated in different media after the rate of temperature rise, which calculates the thermal conductivity of the medium, due to the hardware circuit with automatic zero adjustment circuit and Computer control makes testing simple, fast and accurate. Field application shows that the test results are satisfactory.
