According to the technology of situ electrical heating on oil shale, a physical model was established by FLUENT. Numerical analysis of temperature field distribution of oil shale was carried out. In this model, the healing efficiency was increased by time, which was obviously increased when the heating well and oil well exchange heating. When the heating time was less than 3 a, the temperature of oil shale layer was increased steadily. But it did not reach the temperature that oil shale pyrolysis required. When the heating time was greater than 3 a, the temperature of oil shale layer was reached to 350～500 ℃. And it reached the temperature that oil shale pyrolysis required. After pyrolysis, the thermal conductivity, porosity and permeability of oil shale were increased while the temperature was elevated. Therefore, the analysis and control of temperature field of oil shale was helpful to improve the heating efficiency and production of oil shale.

If product oil pipelines were constructed in the areas of complex topography, parts of pipelines would inevitably encounter some problems via the large gap areas. Due to the existence of pipeline crossing point and the physical difference of the transport oil, it may appear the phenomenon of slack flow in the downhill pipeline. According to all kinds of operating conditions, it may appear via the large gap areas. Based on VOF multiphase flow model numeral simulation was built to research the influence of slack flow features for different angles, different pipe diameters and flow velocity. Through the computer analysis, it elaborated the influence factors of the discontent flow phenomenon for product oil in a large gap location. The results provided theoretical guidance for the design of transport pipeline in mountainous areas.
