摘要:
针对稠油油藏开发过程中油水在相同的压力下的两相流动,在实验室中研究恒压下的油水产出规律。利用恒压阀调节气瓶压力,在恒压下将分别装在2个中间容器中的稠油和地层水同时注入饱和水的人造岩心,研究产液机理和规律。实验发现,产液受注入压差控制,注入压力梯度增加,产水量增加,产油量变化很小,水油比增加。实验结果表明,在稠油和水两相流动中,增加生产压力梯度提高了产液量,但并不能提高采收率。
Abstract:
In view of the two-phase flow of oil and water under the same pressure during the development of heavy oil reservoir, research is conducted on the mechanism of oil and water output under constant pressure in the laboratory. In order to probe into the fluid producing mechanism and law, constant-pressure valves are utilized to adjust the pressure of gas bottles, artificial cores of saturated water are simultaneously injected into the heavy oil and the formation water separately filled in two intermediate containers under constant pressure. The experiment shows that the production of fluid is controlled by the pressure difference. As the injection pressure gradient increases, water production increases, oil output changes little, and the ratio of water to oil increases. Results show that fluid production is raised by increasing the gradient of drawdown pressure in the two-phase flow of heavy oil and water. However, oil recovery can not be so enhanced.
