Experimental and Parametric Design of Petroleum Back-pressured Hydraulic Impactor

Percussive-rotary drilling technology was considered many years ago as one of the best approaches for hard rock drilling. It is a key for popularizing this technology on a large scale to design and make an impactor with excellent performance. This paper presents a suit of method to design the percussive parameters for the oil or gas field by introducing the working principle of back-pressured impactor, dividing the working periods of impactor into three phases and establishing the computer emulational model of percussive parameters. It draws a comparison between the results of model calculation and experiment on the basis of analyzing the experiment results of impactor. The conclude provides credible foundation for designing and further ameliorating the impactor.     

Origin of immature sulfur-rich oil in Jianghan oil field

Chemical structure of immature sulfur-rich kerogen and composition of immature sulfur-rich crude oil in Jianghun oil field have been studied. In molecular level, crude oil differs from thermolysed and chemolysed products of kerogen but does resemble the bitumen in immature sulfur-rich source rock. Therefore, immature sulfur-rich oil may be derived from the expelling of bitumen rather than from thermal cracking of kerogen.     

超大比表面石油沥青基碳纤维微电极研究

作者研制了一种以石油沥青基碳纤维为电极材料的微电极,基于此种材料的特殊性能,经氧化处理后可获得较一般微电极为大的比表面积,因而其电流响应亦较一般微电极为大。且由于其表面在一定条件下可生成大量的碳氧基团,故其电极电位会随溶液ｐＨ值而线性变化,以至该电极亦可用作测量ｐＨ值的微电极。     

白花茵陈茎叶中挥发油化学成分的研究

分别采用水蒸气蒸馏和石油醚萃取法提取白花茵陈中的挥发油,并通过GC-MS对其化学成分进行了分析鉴定.结果表明,2种方法提取的挥发油的主要化学成分基本相似,主要为萜烯类及其含氧衍生物（如百里香酚和香荆芥酚）和脂肪酸及其酯等.
