簡介:威德福國際最近利用其新產品,旋轉導向鉆井系統(RSS),在肯塔基州一干氣環境下鉆進,通過定位鉆進方向,可以保證井眼軌跡更精確,與普通的推進式鉆頭系統相比,效率大大提高。同時井眼更光滑,也減少了卡鉆事故,為更好套管作業做好了準備。


Weatherford International recently completed its first runs using a rotary-steerable system (RSS) to drill with dry air in the Lower Huron formation in Kentucky. The company reports that this is the longest single run with RSS technology in a dry-air environment.
The assembly included a Revolution Plus RSS, a point-the-bit system which orients the drill-bit axis in the desired direction and focuses cutting action on the face of the bit. This reportedly provides for more precise steering on all types of well trajectories, and differentiates itself from push-the-bit systems, which rely on side-force and side-cutting action.

Weatherford states that the Revolution system provides smoother wellbores, which reduces the risk of stuck pipe, provides easier tripping and casing running, and lowers costs for drilling fluid and cement. Smoother wellbores also create easier setting environments for expandable well screens, according to the company.

For the recent dry-air drilling record, the system successfully drilled a 6,125-ft (1,867-m) lateral section with 4 ¾-in. tools, where conventional operations had been limited to a maximum 5,000 ft (1,524 m), the company states. The section was drilled in 46.35 hours at an average penetration rate of 132 ft/hr (40 m/hr) in 100% dry air.
