The relation of oil removal rate from aluminium alloy surface and NaOH concentration, solution temperature, soak time and stirring intensity was studied. With orthogonal test, the process conditions were optimized. In test conditions, the order from big to small of influence factors is:the reaction temperature,soak time,NaOH concentration,stirring intensity. The optimized process conditions are as follows: solution temperature 60 ℃, soak time 20 min, NaOH concentration 90 g/L and stirring intensity 400 r/min. Under the optimized process conditions, the oil removal rate reaches above 99%.

HZSM-5 was loaded on the cordierite monolithic, and the effect of porous size of the carrier, solid content in slurry, solvent and binder on the loaded amount and loaded quality has been studied. The results show that the big channel, high solid content and the addition of ethanol solvent could increase the loaded amount of the active components in each immobilization process, yet the loaded quality of HZSM5/monolithic catalyst was decreased. While silica sol could significantly increas ethe loaded quality of HZSM5 on monolithic. In conversion of methanol to gasoline, HZSM-5/ monolithic catalyst exhibited high methanol conversion, and oil yield could reach 30.53% at 380 ℃.

When it is transferred the high-pour-point and viscous crude oil, heat loss was serious. And the heat loss was more serious after fault shutdown. When the shutdown time is beyond the safe shutdown time accident occurs. It is important to study the heat calculation of crude oil. Compared the winter and summer shutdown temperature drop of the crude oil. Different shutdown time was given, simulated the temperature drop of each time. Calculated the out-station temperature of shutdown crude oil. Simulated the threedimensional temperature field of soil and pipeline after the shutdown. Concluded that the change rules of crude oil and the soil temperature field at different temperature. When the outstation temperature reach a certain temperature, it can ensure shutdown and restart safety. The result provided a reference for the safety production.

Based on China petroleum strategy reserve and the development trend of large-scale storage tank, the idea of referring the advancement of foreign tank design standards was raised. In allusion to the tank operation management and tank safety, the advancement of American and Russia tank construction standard was studied in detail, including strictly limited tank safe distance and fire-dike effective volume, and advanced design idea of tank level gauge and adjacent tank cooling method under tank fire accident and the mature recommended practice of floating tank roof condition monitoring and tank leakage protection, and the new technology under liquid foam injection and tank foundation drilling leakage inspection technique. Finally, the suggestion of adopting American and Russia tank construction standard was made.

If product oil pipelines were constructed in the areas of complex topography, parts of pipelines would inevitably encounter some problems via the large gap areas. Due to the existence of pipeline crossing point and the physical difference of the transport oil, it may appear the phenomenon of slack flow in the downhill pipeline. According to all kinds of operating conditions, it may appear via the large gap areas. Based on VOF multiphase flow model numeral simulation was built to research the influence of slack flow features for different angles, different pipe diameters and flow velocity. Through the computer analysis, it elaborated the influence factors of the discontent flow phenomenon for product oil in a large gap location. The results provided theoretical guidance for the design of transport pipeline in mountainous areas.

There were two advantages of composite applications of microbe and surfactant: on the one hand, surfactant enhanced the capability of microbe in emulsion and Viscosity Reduction; on the other hand, the microbial nutrient solution could reduce the loss of surfactant adsorption in the shale and ineffective in the reservoir, so microbe and surfactant tended to have synergistic reaction. Five type surfactants were selected that surfactant HSB12 and OPS could be reduced to ultralow interfacial tension between oil and water. Surfactant HS B - 1 2、 OP - 1 0could emulsify and reduce the viscosity of crude oil. The effect of surfactants  HS B - 1 2、 F P 3+OP - 1 0 on microbes could be ignored, and microbe/surfactant combined flooding was obviously better than single surfactant flooding or microbial flooding.The maximum of recovery reached 9.67%.

Volcanic-rock reservoir belongs to extremely low permeability gas reservoir. However, as with natural holes and rifts, it can be for industrial development. Relative permeability curve is an important data for dynamic analysis and numerical simulate of gas reservoir development. It illustrated by the case of a Jilin Province's volcanic-rock gas reservoir, and measured the relative permeability curve by unsteady-state water displacement by gas. The results show: It had a high bound water saturation, residual gas saturation and water saturation in isotonic point; it also had a low relative permeability in isotonic point and a low water relative permeability in endpoint; confining pressure and displacement pressure had a significant impact to the results; volcanic-rock reservoir had a serious heterogeneity.

The immersion and electrochemical methods has been used to study the corrosion behavior of automotive steel Q255 in different content of snow melting salt (NaCl) solution. Immersion test show that, the snow melting salt solution is more corrosive than the natural snow solution. The corrosion rate of Q255 steel in the natural water water is smaller than that of the snow melting salt solution, with the corrosion rate of 0.021 07 mm/a after the immersion of 168 h.The corrosion rate increased with the increase of NaCl concentration of the snow solution. The corrosion rate of Q255 steel could reach 0.039 71 mm/a in 3%NaCl solution, the value of which was almost double to the natural snow solution. Electrochemical experiments show that, the presence of chloride ions accelerated the dissolution and mass transfer process of F e 2+ corrosion products, subsequently reduced the adhesion of the corrosion product. Accordingly, the corrosion products would not be able to protect the steel surface, thus the corrosion rate accelerated.
