桥式偏心分层注水水嘴选配方法研究

Selection method of throttle for bridge type eccentric stratified waterflooding

桥式偏心分层注水是国内应用最广泛的分层注水技术,是油田开发过程中解决层间矛盾、提高水驱动用程度的重要手段。但是,现场选配桥式偏心水嘴多依靠技术人员的经验,缺乏系统的理论支持,水嘴适配成功率低,需反复测调投捞。文中利用流体力学、高等数学和计算机技术等理论方法,建立了水嘴选配的相应模型,并根据模型编译了水嘴选配程序,使水嘴一次选配成功率得到有效提高。

Bridge type eecentric stratified waterflooding is the most widely used in China and it is an important means to solve the contradiction between layers in the process of oilfield development and to improve reservoir producing ratio for waterflooding. Field selections of throttle for bridge type eccentric stratified waterflooding more rely on technician＇ s experience, but there is a lack of systematically theoretical support, having low success rate and needing repeated testing. This paper makes use of the theory methods of fluid mechanics, mathematics and computer technology, builds the corresponding model of throttle selection. Based on the model, the program of throttle selection is compiled. The success rate of throttle selection can be improved effectively.
