2014年4月1日 · The mechanical properties of conductor in two conditions were analyzed, including Cam Activated Drilling Ahead (CADA) tool releasing stage and surface casing cementing stage, and the soaking time windows of the two stages were designed.

2022年4月28日 · The CADA allows you to jet in surface pipe and drill out without making an additional trip out of the hole. The 36" relies on skin tension to stay in place, and after observation from the ROV the ...

2022年9月22日 · The CADA tool consists of setting-guiding mechanism, locking and releasing mechanism, working status indicator, sealing system and maintenance components. During the jetting installation process, the drilling tool assembly and the conductor string are connected together by the CADA tool (Fig. 4.5).

2020年5月8日 · Run the BOP with the riser already connected on its top. The BOP is then landed on the high-pressure wellhead. With the BOP and riser in place, the operation to drill the next section can be carried out. Fig.6—Cam-actuated drill-ahead (CADA) tool (courtesy of Dril-Quip).

2017年4月30日 · The conductor jetting operation was performed using a special conductor running and drillout tool, the Dril-Quip Cam Activated Drill Ahead Tool (CADA tool), which allows each new section to be drilled without tripping for a new BHA.

2024年10月1日 · Simulated CADA Tool: This device connected the simulated casing and drill rod, enabling axial displacement adjustments of the internal simulated drill rod through threaded fittings and screws, ranging from −127.0 mm to 304.8 mm. The tool is designed to withstand both tensile and compressive forces during drilling.

2022年6月20日 · The structural components and operation principles of the CADA tool were introduced . The mechanical characteristics and parameter sensitivity anal ­ysis on the key components of the CADA tool were studied considering the working process and working load of the CADA tool during service .

2022年1月1日 · The running assembly for deepwater conductor jetting is usually assembled with a CADA (Cam-Actuated Drill Ahead) tool, which locks the conductor, and a bottom hole assembly (BHA) to jointly form a combined pipe string (Ma and Song, 2006; Deng et al., 2012). Thus, in the underwater injection process, there is no relative displacement along the vertical direction between the conductor and ...
