阿尔及利亚某油田富气混相驱长岩芯物理模拟

结合长岩芯（细管）实验结果，利用长岩芯驱替实验评价了富气混相驱注入时机、注入方式以及注入量对混相驱效果的影响。在油藏条件下，液化石油气与天然气摩尔比为36:64时，混相流体与地层原油能完全混相，与水驱相比，提高采收率在15%以上。在注入工艺参数中，早期注入有利于提高采油速度，交替注入有利于控制气窜，注入量对驱替效果和后续水驱压差影响较大，建议用数模方法优化注入段塞大小。

Reflections on Education on Ideal and Belief of Student and Young Teacher Party Members

Ideal and belief are the major source of power and spiritual support of a nation and an individual which contribute greatly to social and personal progress. Student party member is the most remarkably increasing group of party members,and young teacher party members in universities are young pioneers who devote their intelligence and energy to teaching and student cultivation. Therefore,it is important to enhance education on ideal and belief of party members among college students and young teachers under the guidance of the spirit of reform and innovation and ensure that they correctly understand the meaning of ideal and belief,comprehend deeply the content of ideal and belief education so that they can develop a firm belief in Marxism and integrate personal development with the great cause of the communist party.
