摘要
水平井技术具有控制面积大、产量高、控水效果好的优势。新海27块由于油水粘度较大、边底水活跃,油藏底水锥进严重,现已进入高含水低速采油阶段,目前开发方式条件下,井间剩余油难以有效动用,因此考虑利用先进的水平井技术来有效动用井间剩余油,控制底水锥进,提高采收率,进一步改善油藏的开发效果。为此使用三维地质建模软件Petrel在目标工区建立构造模型,属性模型,最后和开发数值模拟结合建立剩余油分布规律模型,利用Petrel强大的井轨迹设计模块完成井轨迹设计。
Horizontal well technology has the advantages of large area,high jield and good water control effect.Because of high oil and water viscosity,active edge-bottom water and serious bottom water coning,Block 27 of Xinhai has been in the stage of high water cut and low speed production.Under the conditions of current development methods,cross-well remaining oil is difficult to be exploited effectively.Therefore we consider using advanced horizontal well technology to develop the remaining oil,control bottom water coning,enhance oil recovery and improve the effect of reservoir development.3D geologic modeling software Petrel is used to establish the structure model and attribute model in target work area.Then combination of remaining oil distribution law model with development numerical simulation is used to complete well trace design with the powerful Petrel module.
