摘要:
为了解决分层注聚中聚驱试剂井下低剪切配注问题,提高聚驱试剂驱油效果,本文综合比较了三种阀芯结构,进行了阀芯室内水利特性试验,并进行了阀芯网格划分,流场动力学仿真,得出了流线型降压槽结构对聚驱试剂剪切率低、限流阻力大、粘度损失小且减少了更换频率。运用FLUENT 软件模拟出流线型降压槽结构不同槽数的阀芯对粘度损失率和节流压差的影响,有效控制注入量为 120 m 3 /d,可产生控制压差为 3. 0 MPa,粘度损失率为 <12%。提高了产油量,为聚驱分注工具统一奠定了基础,对注聚区的稳定开发提供技术支撑。
Abstract:
In order to solve the separate layer polymer injection in polymer underground low shear injection allocation problem and improve the oil displacement effect of polymer,this paper compares the three kinds of valve structure,spool indoor test,and a valve core grid partition,dynamic simulation of flow field. It is concluded that the streamlined pressure relief groove structure of polymer shear rate is low,the current limiting resistance, viscosity loss small,cast fishing success rate is high. Injection allocation device resistance flow section adopts the streamline relief groove structure,using FLUENT software to simulate the aerodynamic pressure relief groove structure and different numbers of slots in the spool to the viscosity loss rate and the throttle pressure difference effect,when the flow in the range of 25 ~170 m 3 /d can produce pressure 1. 6 MPa,shear degradation rate of less than 6. 5%. To improve the oil production,Increase oil production,which laid a foundation for polymer separate injection tools and unified,the stability of polymer injection development to provide technical support.
