2.Fabrication and Electrochemical Characterization of PAMS-based Gel-polymer Lithium Batteries
3.Five oilfield tests of water shut-off showed that treatments to use an amphoteric ion polymer gel or an inorganic system of lime-cement as plugging agents could neither decrease water cut nor increase oil production. Producers could be shut-off with inorganic silica gel-polymer gel seal, or with pre-crosslinking swellable granules made from plant fiber-polymer gel seal, which resulted in output decrease of both oil and water.
7.A newly developed heat resistant (90℃) and salts tolerant (TDC≤1.6×10 5 mg/L) terpolymer of acrylamide is put into enlarged experiments of synthesis in small batches as solid gel and used in a pilot polymer flooding trial at Zhongyuan. It is observed in the flooding trial that the viscosity of solution prepared at the site is lower by 69% than that determined in laboratory (η 0) for first experimental tercopolymer samples.
9.Rare earth strontium aluminate long afterglow luminescnet material SrAl2O4:Eu2 +, Dy3+ Was syntnesized by sol-gel with Al(No3)3, Sr(No3)2, Eu2O3, and Dy2O3. The polymer Cement long afterylow luminescent coating was Prepared by adding proper strontium aluminate powders, white cement and other aids into polypropylene emulsion of nucleon-shell structure.
