Product Introduction Puyang Zhongshi Group Co., Ltd, a professional manufacturer of oilfield cementing accessories, has introduced its high-performance 7" Reamer Shoe (Model: RS07000850) for reliable casing cementing operations. Combining the guiding function of a conventional guide shoe with the reaming capability of a reamer, this tool helps operators overcome tight hole sections, ledges and debris while ensuring smooth, efficient casing running and cementing. What Is a Reamer Guide Shoe? A reamer guide shoe, also known as a reaming shoe, is installed at the bottom of the casing string. During tripping-in, it performs two core functions: it guides the casing into the wellbore along the correct path, and its hardened reaming blades actively mill away obstructions, key seats and mud cake buildup so that the casing can pass through difficult intervals without getting stuck. When circulation and cementing begin, the shoe's flow ports deliver cement slurry efficiently to the annulus, ensuring complete zonal isolation. Key Features Eccentric Aluminum Guide Nose: The streamlined eccentric nose design centralizes the casing string, minimizes the risk of hitting ledges or washouts, and is easy to drill out after cementing. Six Tungsten Carbide Reaming Blades: Six hard-faced blades provide aggressive yet stable reaming performance, effectively removing tight spots, key seats and debris to reduce stuck-pipe risk. Optimized Cement Ports: Three Ø25 mm and three Ø20 mm flow ports allow smooth cement slurry displacement and help achieve uniform annular fill for better zonal isolation. API 5CT L80HC Body: The body is manufactured to API 5CT standard in L80HC grade, delivering high strength, hardness and wear resistance for demanding downhole conditions. Premium Casing Connection: The shoe features a standard 7" casing box thread (26 lb/ft), ensuring a secure, high-integrity, leak-proof connection with the casing string. API Class G Cement Fill & API RP10F III C Valve Seal: Standardized cement fill and valve seal grades guarantee consistent, high-quality cementing performance. M20 Set Screws: Two M20 set screws securely lock the internal components in place during running and cementing.
