摘要
为解决复杂井修井作业过程中常规单一解卡打捞工艺成功率低,施工周期长的问题,研制了一种液压增力打捞器,详述了液压增力打捞器的主要结构,工作原理和主要技术性能参数,并配套了震击器、加速器等辅助工具,形成了液压复合解卡工艺技术,并在大港油田板X井进行了现场应用.应用结果表明,该工艺不仅具备了液压增力解卡和液压增力震击解卡两种功能,而且可快速提供上提拉力和上提速度,直接将解卡上提力作用于井内卡点位置,避免了井身结构和人为因素的影响,提高了解卡打捞成功率,缩短了施工周期,具有较广泛的应用前景.
Abstract
In order to solve the problems of low success rate and long construction period of conventional single stick-freeing and fishing technology during the process of complicated wells repair well operation,the new type of hydraulic reinforced force salvage tool was developed.The main structure,working principle,as well as main technical performance parameters of the hydraulic reinforced force salvage tool was recounted,equipped with auxiliary tools such as drilling jars,accelerators,etc.The hydraulic composite stick-freeing technology of complicated wells was formed,and was carried out field application in Dadang Oilfield ban X well.The field application results show that the the hydraulic reinforced force composite stick-freeing technology not only has two functions:hydraulic reinforced force stick-freeing and hydraulic reinforced force jarring stick-freeing,but also quickly provides the lifting force and lifting speed,directly acts on the position of the stuck point in the wellbore with stick-freeing lifting force,avoiding the influence of the well deep structure and human factors.It improves the success rate of the stick-freeing and fishing and shortens the construction period,with more extensive application prospects.
