Based on the theories of rheology, Non-Newtonian Fluid Mechanics, petroleum chemistry, crystallography and pipeline technology etc. and sampling Huabei crudes, experimental indexes and programmes are drew out, integrating the oil properties and parameter analysis; in terms of the macro analysis of continuum mechanics, substantial experiments are conducted with HAAKE RS600 rotational rheometer and the rheological equation as well as the viscosity-temperature equation are further developed with tested rhrogramme and viscosity-temperature curve, respectively. Beased on the researches on thixotropic mechanism and thixotropy fluid property, hysteresis loop curve, structure failure and viscosity build-up curve as well as shear stress decrement curve for one type oil are first present in this paper. According to the theoretical researches and testing results, a novel thixotropy equation with τ=τ_∞e~ pattern, which is of hi-accuracy, few parameter and simplicity, is developed. Considering the influence of various parameters on rheological behaviour, depressant adding condition is optimized and experimental evaluation on BEM-5P is conducted, which further unrip its mechanism on the Huabei crude. A corresponding viable pipe transportion programmel is also recommended.

However, the ratio of the unsaturated and saturated fatty acid amide is relatively stable in downcore indicating that there is no selectivity between those two types of fatty acid amides during diagenesis processes, including biological, chemical and physical degradation. For this reason, we suggested that the depositional environment in Qarhan paleolake was relatively aerobic during the organic component deposition.

另一方面，不饱和脂肪酸酰胺与饱和脂肪酸酰胺的相对量的比值在剖面上并没有呈现明显下降的趋势，说明各种生物、物理及化学作用对饱和与不饱和脂肪酸酰胺的降解过程不存在明显的选择性，指示了有机质在沉积过程中处于一个偏氧化的环境。
