渤海油田低效井浅层侧钻方案设计优选
|
摘要
近几年渤海油田低效井侧钻设计的工作量大幅度增加,为了降低低效井侧钻的成本,针对浅层侧钻方案设计存在多种可行方案的情况,以A1H1、A2H1、A3H1三口井的方案优选过程为例,结合老井槽口位置、套管程序、固井水泥返高和作业机具等因素,评估每种方案的作业难度、作业费用以及后期井眼再次利用的情况,优选设计方案。现场实施结果表明3口井所选侧钻方案合理,能够最大限度地降低侧钻井的作业成本。优选过程对渤海油田低效井浅层侧钻方案设计有一定参考意义。
Design for inefficient well sidetracking of Bohai oilfield increased greatly recent years.In order to reduce costs of shallow sidetrack,take A1 H1、A2 H1、A3 H1 for example,different sidetracking design were contrasted combine with slot position,casing program,TOCand operating equipment.Appropriate design was chosen with specific circumstances of original well.The field implementation results showed that the selected sidetracking design is reasonable which reduce the cost mostly efficiently.The optimization progress has certain reference significance to design of shallow sidetrack in Bohai oilfield.
