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.     

Comprehensive evaluation of mechanism of “chimney effect” using principles of magnetism, geochemistry and mineralogy

Study of forming mechanism of "chimney-effect" (CE) has important significance for basic theory and applications of non-seismic geophysical and geochemical methods locating oil/gas reservoirs. The theoretical basis of comprehensive evaluation of mechanism of CE using principles of magnetism, geochemistry and mineralogy has been reviewed, with the problems to be solved: (ⅰ) study for the relationship between process of oil/gas migration and geochemical field; (ⅱ) analysis of genesis of magnetic, geochemical and mineralogical anomaly; (ⅲ) interpretation of surface soil magnetism and geochemical anomaly combined with seismic data.

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。     

Estrogen and accessory sex gland lipids

Summary Administration of estradiol-17 elicited differential responses on accessory sex glands of rats. In caput epididymis, the estrogen treatment led to an accumulation of glycerides and phospholipids while in cauda epididymis, there was no significant change. However, in seminal vesicles, depletion of phospholipids was observed In prostate, the treatment, resulted in an accumulation of glycerides.Part of Ph.D. Thesis. Umapathy, E., Thesis.

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.     

济阳坳陷车西洼陷漫湖洪水—风暴沉积与砂体横向预测

渐新统沙二段是济阳坳陷车西地区的主力油层,为了弄清其油气分布和控制因素,综合利用大量的地质和地球物理资料,首次在该段识别出漫湖洪水—风暴重力流沉积.该沉积具有明显的重力流沉积特征,砂岩的成分和结构成熟度均较低,粒度概率图多由悬浮次总体组成,沉积序列可用Bouma序列来描述.在明确了砂体的沉积层位和沉积边界的基础上,描述了漫湖洪水—风暴的沉积特征并建立了沉积模式,系统分析了这个环境下储集性砂体的分布及其油气聚集特征,为车西洼陷的进一步勘探指明了方向.     

二元复合驱体系中钠型蒙脱土的表面电性质

利用电势分析仪分析了石油磺酸盐及部分水解聚丙烯酰胺（HPAM）对钠型蒙脱土ζ电势的影响，采用X射线衍射（XRD）测定了钠型蒙脱土于石油磺酸盐、HPAM溶液中结构的变化。结果表明，石油磺酸盐、HPAM均能使钠型蒙脱土的ζ电势变得更负，而且使钠型蒙脱土的XRD峰发生明显的变化，说明HPAM和石油磺酸盐不仅可以吸附到蒙脱土的表面，而且可以吸附到蒙脱土的层间结构中。
