1.Top quality hydraulic pump with welded construction Hard chrome plated pistion and pump plunger ensure durability and corrosion resistance.
2.Owing to the effect of glucocorticoid, promoting Bone substance absorption, the male pregeriatic SD rats Had been injected intramuscularly with dexamethasone In different dosages(0.05,0.1,0.4mg/100gBW),and thereafter, the changes in bone density of whole body, volume of bone trabeculae, and intensity of anticurvation were observed.
3.Oil filler plug: It is necessary to fill No.30 machine oil or No.20 gear oil before using aerator, until oil reaches oil plug hole on the side and overflows.
5.The ASP FOAM EOR mechanism, basic mathematical models and numerical models and solution method of the program are introduced. Core flooding by ASP FOAM is simulated and shore plug is feasible in pilot. Examples indicate that ASP FOAM raises oil recovery by 30 percent in comparison with water flooding, 10 percent with ASP, 7 percent with ordinary foam drive.
7.Open upstream slowly, fill the valve and bleed the air through Test cock 2, 3 and 4.
8.Plasma-filled Dielectric Cherenkov Maser Excited by an Annular Relativistic Electron Beam
10.for the waterflooding blocks with the water cut of above 98% , higher recovery efficiency is obtained by injecting polymer slug firstly and then injecting the activated water slug of SLB surfactant than by directly injecting SLB surfactant - polymer compound slug.
