It points out that the episodic hydrocarbon expulsion in Mosuowan area is different in Pen 5 and Pencan 2 well field,and the scale is large in the former and very small in the latter,so the low density and high maturity oil fills and entraps to reservoirs overlaid overpressure strata largely in Pen 5 well field,but little in Pencan 2 wel.

Episodic evolution model of boundary fault and its controlling function to petroleum systems in western Wuerxun depression

The tectonic evlution of Wuerxun depression in Yimin period is characterized by universal development of detachment- type structure styles, which are formed by episodic tectonic evolution, persistent sliding of Wuxi fault in low angle and within the bounds of three stiff basement blocks.

The result shows that the fault activates are strong in Es3,E1s2,and the fault activity is episodic,the 1st episodic is Es3 the 2nd is Eh,the 3rd is Em and continues to the present situation,of which the 3rd episodic fault strength is little,and similar to the Eg.

Actuality and Prospect of Research and Development of Foaming Master Batch of Polyolefin;

Current Situation and Developing Tendency of Flame Retardant Polyolefin;

Advances and development proposal in single-site catalyst of polyolefin;

The market demand of poly-α-olefin(PAO) in synthetic oils was one of the fastest growing,the PAO synthetic lubricants not only have the advantage of lower volatility,higher viscosity index,lower pour point,higher flash point and excellent high temperature anti-oxidation performance,but also have long use life compared with mineral oils.

As the regulation of lubricants is becoming more and more strict, demand of high quality lubricating oils is increasing, among which most distinctly is synthetic oil, especially poly-α-olefin synthetic oil.

By employing orthogonal design L9(33),effects of polymerization temperature,catalyst quantity and reaction time on the conversion of olefins and the viscosity of poly-α-olefin lubricating base oil were studied.
