Under the constraints of high temperature and heterogeneity, the common profile control agent can not effectively plug the steam channeling. To address this issue, it is necessary to develop the high temperature resistance steam channeling plugging agent to improve the steam suction profile in the heavy oil reservoir. This paper used Simple Variable Method to optimize the content of the components of the high temperature resistant plugging agent. Static performances evaluation aims to study the influence rules of the formation condition (temperature, salinity and pH value). Dynamic evaluation is used to study its performance (plugging ratio, residual resistance factor, scouring resistance and thermal stability) in the sand-filled pipe to testify its applicability. The ratio of the component and the injection sequence are shown as follows: 0.03% coagulant +2.2% cross-linking agent I + 1.2% cross-linking II + 6% high efficient main agent. The evaluation experiment results show that the gel can resist at least 280ºC, the plugging ratio is above 93.1%. The plugging ratio only have a 8.43% reduction after scoured by 15 PV steam (280ºC). After a 10-day thermal stability experiment (280 ºC), the plugging ratio is still above 80%. The result indicated that the plugging agent is suitable for the improvement of steam suction profile. The suggested way of injection is also provided.

And Performance

During the last two decades, a large effort has been devoted to improve the safety and performance of Li-ion batteries. Current commercial electrolytes are based on highly flammable solvents that make them dangerous for certain applications. Organosilicon (OS) electrolytes are a good alternative to conventional carbonate electrolytes. Silatronix has developed many organosilanes containing ethylene oxide units for \(Li^+\) coordination. These OS have properties suitable for their use in electrolytes including high thermal stability, high flash point, low vapor pressure and relatively low viscosities. The OS electrolytes are less flammable than commercial electrolytes, hence improving the safety of the batteries and have shown a performance comparable with the current standard electrolytes when used in Li-ion coin cells. Fluoroorganosilanes (FOS) have been found to be the best candidates for commercial application and have been successfully tested in coin cells at high temperature.

Ordered-alpha titanium alloys having a DO19 type structure have good potential for high temperature (600°C) applications, due to the thermal stability of the ordered phase and the inherent resistance to recrystallization of these alloys. Five different Ti-Al-Ga alloys consisting of equal atomic percents of aluminum and gallium solute additions up to the stoichiometric composition, Ti3(Al, Ga), were used to study the growth kinetics of the ordered phase and the nature of its interface.The alloys were homogenized in the beta region in a vacuum of about 5×10-7 torr, furnace cooled; reheated in air to 50°C below the alpha transus for hot working. The alloys were subsequently acid cleaned, annealed in vacuo, and cold rolled to about. 050 inch prior to additional homogenization
