Melting experiments on aIkalic and tholeiitic rocks containing about 2 % water were made at 850- 1300℃ and 1. 5-3. 5 GPa. The results showed that: (1 ) partial melting of tholeiitic rocks with saturated water would produce granitic magma, but only tonalitic magma with unsaturated water;
In this paper, bulk water, degassed oils with different viscosity, water-saturated and oil-saturated Berea sandstone and carbonate were selected to perform NMR experiments at temperatures ranging from 25℃ to 90℃.
For several groups of reservoir cores deoiled, water saturated and flooded with oil to irreducible water state, MDFF gives rise to enhancement in oil recovery as follows: 60.8% and 64.1% in the case of injecting 500 mg/L solution discontinuously;
By the Monte Carlo method, the changes of detector tallies in formation radial, longitudinal direction and space has been simulated for the formation of water saturated limestone with 20% porosity. Thus, the relationship between detector tallies and formation radial depth is gained.
The wavelength-to-characteristic fractural scale ratio is an important factor whether the equivalent medium theory is correct or not, the anisotropic degree decreased when the fracture is water saturated, the fractural density has certain influence on P-wave propagation velocity and attenuation factor.
Experiments were conducted on natural, water saturated and water gas saturated coal samples to compare their mechanics. The results indica that elasticity modulus, compression strength and volume compress coefficient of natural coal samples are larger than those of water saturated coal samples and the latter are larger than those of water gas saturated coal samples.
The porosity and percentage of tiny sand (diameter 0.05-0.1 mm) and clay particle (diameter >amp;lt; 0.05 mm) increased, bulk density in surface soil decreased, and saturated water-holding capacity improved.
The saturated water content, field capacity and wilting point decreased with increasing soil depth.
The contact angle in saturated water vapors, θv = 84°, was calculated from these values.
Single-step distillation with overheated steam in a vacuum or with saturated water vapor at atmospheric pressure provides transfer into the distillate of the whole amount of the solvent, permitting the use of any diluent.
