Influence of Testing Media on Primary Bubble Point Pressure of Metallic Fiber Felt 介质对金属滤毡初始气泡点压力的影响
The effect of testing media type and environmental temperature on the primary bubble point pressure of metallic fiber felt was studied according to the national standard. 依据国家标准,研究了介质类型和环境温度对滤毡初始气泡点压力的影响。
And ( 4) the formation pressure should be kept above the bubble point pressure. 保持地层压力在泡点压力以上。
An experimental study of bubble detachment point in sub-cooled boiling at low pressure and velocity 低压低流速下过冷沸腾汽泡脱离点的试验研究
When applied to low-pressure polar systems, the new model had the same accuracy for the vapor composition and better result for the bubble point pressure as compared with the common activity-coefficient models. 结果表明:对低压极性体系,汽相组成的绝对偏差和常用的活度系数模型相当,而压力的绝对偏差则略好于上述模型。
Oil bubble point pressure of oil gas water samples were measured with GF731 high pressure physical property apparatus. 对现场获取的油气水试样,用GF731型高压物性仪,测得原油饱和压力值。
During practical production, due to heterogeneity and control ascending of water cut latterly, reservoir pressure will be below bubble point pressure locally. 在实际生产过程中,由于储层非均质性,以及开发后期为了控制含水的上升,油藏中局部地区的压力会降到饱和压力之下。
The switching point between these two phases is decided by the relationship of bubble point temperature at the operating pressure. 而转换点是山工作压力下的泡点温度决定的。
Theoretical Study on the Inflow Performance Relationship of Oil Wells in Reservoir of the Flow Pressure Under the Bubble Point Pressure 流压低于饱和压力油藏油井流入动态方程理论研究
The results show that it is harder for hydrocarbon gas with higher expansion ability to increase bubble point pressure than nitrogen. 研究表明:注氮气比注烃类气更易使泡点升高,膨胀能力不如烃类气强;
Experimental results show that oil bubble point pressure decreases when water cut increases, but decrease of different layer was different. 结果表明,油藏含水率上升,原油饱和压力下降,但不同层位的下降幅度有所差异。
The designed SVR model can also accurately identify the oil formation volume factor under bubble point pressure in a smaller error. 所设计的模型以较小的误差比较准确地确定了原油泡点压力下的体积系数。
