Flow is then stopped, and if the formation has sufficient permeability, the formation will flow to equilibrate the tester with the bulk of the formation.
流动然后停止,而且如果地层有足够的渗透率,地层将会流动,以平衡测试器和地层体积。
Further to this, permeability is worsened, and bulk density decreased.
从而造成透气性差、密度与比重降低。
The soil bulk reduced, the soil porosity and permeability improved.
地块的土壤容重减少,提高土壤膨松度,增强土壤透气性。
Correlation coefficients between the thermal conductivity and bulk density, open porosity, permeability and raw material grade was obtained respectively.
另外,还计算了导热系数与体积密度、显气孔率、透气度和原料等级之间的相关系数。
Fractures in the low permeability and dense reservoir are not only the accumulative bulk, but also can connect the other types of space of reservoirs, and improve the reservoir quality.
在低渗透致密储层油藏中,裂缝不仅构成油气的储集空间,而且连通其他类型的储集孔隙,极大的改善了储集层的物理性质。
Four kinds of amendments can improve soil physical properties. Soil bulk density decreased, soil porosity, permeability coefficient and field capacity increased under treatments.
四种改良剂均能不同程度的改善土壤物理性状,能降低土壤容重,提高土壤总孔隙度,加快渗透速度,增加田间持水量。
