水平井均衡供液完井静态控流参数设计
Design of static lfow control parameters for equilibrium lfuid supply completion of horizontal wells
摘要
Abstract
In view with imperfect equilibrium lfuid supply completion technology for horizontal wells in Shengli Oilifeld as well as the problems such as low single well production, complex producing zones, a set of design methods were established for‘static lfow control parameters’ of equilibrium lfuid supply completion technology, which is divided into four steps in a proper order:division of producing sections, production allocation of each producing section, choke and pressure drop design for each producing section and design optimization of lfow control parameters. Division of producing section is for the purpose of reducing the adjoining zones with great difference in heterogeneity and isolating physical properties of the producing zones; the bottom-water and edge-water reservoirs respectively use the principles of‘consistent water breakthrough time’ and‘equilibrium lfuid supply’ for production allocation of each producing wells;the lfow pressure at heel should be properly established to optimize the choke pressure drop required by each producing well section;the blind screen ratio should be properly selected for lfow control section to ensure that the lfow control screen can give full play of its lfow control performance. The result of example calculation shows that the completion string with equilibrium lfuid supply designed by‘static lfow control parameter’ method has remarkable lfow control effect. This design method is easy and practical, and provides theoretical support for the promotion of equilibrium lfuid supply completion technology in Shengli Oilifeld.关键词
