摘要:
针对松散及破碎层钻进取心率低、岩心结构破坏等技术难题,作者设计形成一套"隔液单动双管半合管取心、SH植物胶钻进液护心护壁、跟管钻进"技术。隔液单动双管半合管取心钻具的钻进液与内管分离,不会直接冲刷、冲散及破坏岩心,保证松散及破碎层岩心可以完整地进入内管;单动双管可以有效保护岩心原始结构。SH植物胶钻进液具有堵漏、携屑悬浮和润滑减阻减振作用,解决了松散及破碎层漏失、塌孔等问题。跟管护壁是在隔液单动双管半合管取心时套管下入孔内,起到护壁等作用。通过在试验区开展取心工作,实现了松散及破碎地层的无扰动、高采取率取心,为今后松散及破碎地层取心钻进提供技术借鉴。
Abstract:
The author designed a set of technology consisting of "liquid-isolating single-acting double pipe semi-closed pipe coring, the core and pipe wall protection with SH vegetable gum drilling fluid, and Casing Drilling Tool", which can solve the problems such as low percentage recovery of core and core structure damage during the drilling in loose and fractured strata. The drilling liquid of the technology "liquid isolating single-acting double pipe semi-closed pipe coring" is isolated from the inner pipe, which can effectively protect the original core structure from being directly washed dispersedly and damaged, so as to ensure the complete extraction of the cores from loose and fractured layers. SH vegetable gum drilling fluid has the functions of plugging, chip carrying suspension, lubrication, drag reduction and vibration reduction, which can tackle down the leakage and hole collapse of loose and fractured layer. Casing Drilling Tool is used to protect the pipe wall when the casing is run into the hole during the coring with the liquid isolating single acting double pipe semi closed pipe. To realize undisturbed and high recovery coring in loose and fractured formations, a lot of drilling work has been carried out in the working area, which can provide a technical reference for the future coring drilling.
