【论文摘要】 介质分离器的发展,无论在陆上还是海上油田都受到密切关注.近期研究除快速、高效分离技术外,又向综合多用方向发展.本研究提出一种集油气水砂分离于一体的新的复合分离器,用离心、膨胀原理的复合旋流器先进行气液或气液固分离,然后用梯型管和螺旋管进行油水精细分离,并把上述功能集中在一个分离器中实现.这一方法使油田上采用了多个分离器的工艺流程,减少为单个分离器装置,这样大大减轻重量,缩小体积.尤其对海上油田,发展深海油气采收具有更重要的意义.本分离方法目前已完成实验室原理实验、华北油田现场实验,正在进行新型样机设计,准备在大庆油田高气液比,并随压力降低油中有气体析出复杂情况下的油井上进行现场试验.水利论文-tct0R,P

.Q \q]\/n&M0【英文论文摘要】 Multiphase separator is always a big concern in oilfields both onshore and offshore.Aside from the endeavor in developing quick and highly efficient separation techniques,recently great attention has been turned to synthesized separation.In the present study,a new kind of combination-type separator is put forward to conduct the separation of oil,gas,water and sand particles.The detailed processes are as follows:in the first step,gas,liquid and sand particles are separated in a built-in hydrocyclone. Then the fine separation of oil and water is performed in T-shaped pipes and helical tubes.All these separation components are assembled inside one separator,and in this way not only the technical processes in oilfield are simplified,but also the volume and the weight of separator are reduced to a large extent.Up till now,the indoor experiments in our laboratory and the field tests in Hua'bei oilfield have been completed successfully. At present,a prototype of combination-type separator is ...更多under design to be prepared for the field experiments in Da'qing oilfield,where the gas-liquid ratio is relatively high and some condensate gas would be released with the decrease of pressure.  还原水利论文g;b0zk,f w$J
