This paper analyzes the factors that influence the foam stability by testing the foam entrainment capability, the dynamic surface tension, the viscoelasticity, the half life period, and the foaming capacity.
通过对泡沫携液能力、动态表面张力、黏弹模量、半衰期、发泡量的测试对影响泡沫稳定性因素进行研究,确定影响泡沫体系稳定性的因素;利用管式模型对泡沫体系在多孔介质中再生能力进行测试,研究再生能力、泡沫稳定性之间关系。
Adaptability of well patterns in Baobei block are analyzed in respects of the types of well pattern, water-injection methods, waterflooding control and the ratio of producing reserves, fluid supply capacity of producers, drive index and so on.
从宝北区块井网型式、注水方式、水驱控制及动用程度、油水井供液能力、驱动指数、油井见效见水等方面分析了宝北区块注采井网适应性,指出了环状注水方式和注采井距不合理是目前井网不适应油田开发需要的原因所在,并在此基础上提出了增布内部注水井点、缩小注采井距、改环状注水方式为排状注水方式、加强内部注水、加大分层改造力度等改善开发效果的措施及建议。
