尾管悬挂器在三维定向井中的应用分析
|
摘要
在?215.9mm井眼中下入?177.8mm尾管是渤海油田常用的井身结构之一,不但节约钻井材料及成本,而且上部井眼的?244.475mm套管有利于修井、增产等作业的实施。但是,在复杂井眼轨迹的三维定向井中,由于坐挂过程中的摩阻大、尾管悬挂器居中效果差等因素,对尾管悬挂器坐挂产生较大的影响。以渤中油田某A13井为例,进行坐挂过程的问题分析,根据井眼轨迹、尾管悬挂器的结构等影响因素,优化作业程序,有效地将坐挂力传递至尾管悬挂器,顺利完成了该井尾管悬挂器坐挂作业,避免了起出尾管悬挂器等复杂的处理措施。为同类型井的尾管悬挂器坐挂作业提供借鉴。
The ?177.8mm liner into the ?215.9mm wellhore is one of the common well structure in Bohai oilfield,not only saving drilling material costs,facilitate the Implementation of workover,stimulation and other operations into the upper ?244.475 mm casing,but in a complex three-dimensional directional well,the large friction,poor centering effect factors of liner hanger and other facts seriously affect the liner hanger smooth ride hanging job.The liner hanger sitting p roblems in A13 well of Bohai Oilfield,and according to the well trajectory,the impact liner hanger structure and other factors are analyzed and summarized in this paper,to optimize operating procedures,which diverted the sit-hanging force to the liner hanger,and the liner hanger sit and hanged successfully,avoiding the complicated processing steps of taking off the liner hanger,etc.It provides the most directly learn and experience for the follow same type of well to sit and hang liner hanger.
