Reamer Shoes are composed of aluminum eccentric toe cap and body. The scraping function of its aluminum drillable eccentric guide head can remove obstacles in the well, and is particularly good at removing low-side debris in horizontal wells. The low-side debris is dominated by the loose rock formations of the Tertiary Guantao Formation and Dongying Formation in the Bohai Basin. Horizontal wells are a very common problem. Aluminum eccentric guide toe body (connected to the casing line) The aluminum eccentric guide toe can bypass and clear obstacles in the well.
Hydraulic rotary guide shoe
It is an efficient casing running guide shoe with a rotating function. It changes the flow pattern of the drilling fluid at the bottom of the hole through rotation, reduces the friction of running casing, improves the cutting carrying capacity of the drilling fluid, prevents the stratum from being stuck when inserted into the formation, and solves the problem of wellbore shrinkage and Problems such as ground collapse
1. The hydraulic turbine power drives the head of the shoe to rotate, guiding the drilling fluid to form a high-speed rotating vortex, thereby cleaning and trimming the wellbore (pipe wall);
2. The guide toe head is made of aluminum or resin eccentric type. When encountering obstacles, it can smoothly climb over obstacles or shrink, and can guide casing strings into the well more effectively;
3. The interior of the body is made of PDC drillable material;
4. Add a spiral scraping wear-resistant belt to the outside and use high-quality tungsten carbide cylindrical inlay.
