富县探区长6段油藏特征与勘探对策分析

富县探区三叠系延长组长6段普遍见到不同级别的油气显示,但试油未能获得工业油流.据分析,该区白垩纪末的抬升和翘倾运动使油气发生了第三次运移成藏,油、气、水重新分布并受储层物性控制.正确勾画出有利沉积相带、针对油藏特征采取更有效的工艺技术,是实现该区勘探突破的关键.     

防盐抽油泵的研制及在文留油田的应用

文留油田因其独特构造和地层特点，抽油井结盐严重，文中通过对油井结盐机理及抽油泵结盐主要形式、原因的分析，有针对性地开发了防盐抽油泵，并介绍了防盐泵的结构和主要技术特点，在实际应用中配套应用相应防盐技术，取得了较好的效果，极大地减少了盐卡泵现象，抽油井检泵周期得以延长，为其它油田类似油井生产管理提供了新方法。     

未来航空润滑油基础油

介绍了未来航空涡轮发动机对润滑油性能的要求:在260,-54℃时,试样运动黏度分别大于1.0 mm2/s和小于15 000 mm2/s,热氧化安定性温度为260~427℃。该要求已超出了目前使用的酯类润滑油所能承受的最大极限。为了满足要求,需开发全氟聚醚、改性硅油、聚苯醚、C-型醚、氟醚三嗪及环三磷偶氮润滑油基础油,它们的使用温度依次为:-34~316,-60~260,5~288,-29~260,-30~343,-15~343℃。     

辽河催化裂化澄清油中间馏分热反应研究

采用先加入絮凝剂脱灰，再经减压蒸馏切割420～500℃馏分的方法，将辽河催化裂化澄清油预处理，考察了澄清油、加入絮凝剂脱灰后的澄清油以及脱灰后再减压蒸馏所得的中间馏分这3种原料在热转化过程中中间相的转化历程，并采用偏光显微镜观察热转化产物。结果表明，澄清油预处理效果明显，所得中间馏分具有较低的H／C原子比（nH／nC）和适宜的组成分布，是生产针状焦的理想原料。热转化产物的光学组织结构属于各向异性发达的广域-流线型结构。     

低渗透油田套管损坏机理分析及防治措施

在注水开发油田,油水井套管损坏是一种极为普遍的现象,但又各具特点.通过对鄯善油田套管损坏井的自身特点进行统计、归纳,深入分析低渗透砂岩油藏套管变形影响因素和作用机理,提出了套管损坏井的预防及相应治理措施.     

华北油田隐蔽油藏勘探实践与认识

随着勘探的不断深入,华北油田富油凹陷构造油藏的勘探程度越来越高,勘探对象日趋复杂,勘探难度越来越大。面临勘探现状,华北油田认真分析勘探形势,立足资源基础,解放思想,积极转变勘探观念,有意识地加强隐蔽油气藏的深入研究与勘探,先后在冀中坳陷的饶阳凹陷、二连盆地的巴音都兰凹陷、乌里雅斯太凹陷等发现了多个规模富集的隐蔽油藏。通过隐蔽油藏的勘探实践,取得了四点主要认识、六点重要启示,对今后深化华北油田隐蔽油藏的勘探具有重要的指导作用。     

安塞低渗油田孔隙结构对渗流特征曲线的影响

渗流曲线的测定是认识油藏流体渗流规律的基础。实验发现安塞油田储集层岩心渗流曲线在低有效净围压下近似表现为两段直线，通过压汞实验和毛管压力曲线数据分析，认为这种特征与储集层孔隙结构有关。在分析渗流特征时应综合考虑孔隙结核特征、流体与孔隙介质的相互作用等因素。     

Synthesis of oleyl oleate as a jojoba oil analog

Synthesis of a wax ester analog of jojoba oil was accomplished from oleic acid and oleyl alcohol with a zeolite as catalyst. A full 2³ factorial design at two levels has been used in the synthesis. The variables selected were temperature, reduced pressure and initial catalyst concentration. The most important variable within the range studied was temperature. Reduced pressure had a negative influence, and initial catalyst concentration showed a positive influence on the process. A response equation has been determined for the yield of ester. The properties of the synthesized product are similar to those of natural jojoba oil.     

Formation of toxic aldehydes in cod liver oil after ultraviolet irradiation

Formaldehyde, acrolein, malonaldehyde (MA), acetaldehyde and propanal produced from cod liver oil upon ultraviolet irradiation (λ_max=300 nm) were derivatized into nitrogenor sulfur-containing compounds and then analyzed by capillary gas chromatography with a nitrogen-phosphorus detector or a flame photometric detector. Acrolein and MA were formed at levels of 10.9±3.06 and 190.2±38.4 nmol/mg of fish oil, respectively. Maximum levels of formaldehyde, acetaldehyde and propanal formed were 7.0±0.90, 49.1±4.5 and 35.8±4.0 nmol/mg of oil, respectively. Formation of propanal in large quantities corresponded to the high content of ɛ-3 fatty acids in cod liver oil.
