Products Description LEANOMS
Odex casing system is a type of drilling system used in the field of geotechnical engineering and mineral exploration. It is a down-hole hammer drilling method that allows the drilling of boreholes in hard rock formations. The system consists of a special drill bit that is driven into the rock by a percussion hammer, and a casing that is simultaneously advanced into the borehole to prevent the hole from collapsing.
The Odex casing system is designed to be used in difficult drilling conditions, such as fractured and unstable rock formations. The system allows for a more efficient and faster drilling process, as it eliminates the need for drilling fluids and other supporting structures. It also reduces the risk of borehole collapse and makes it possible to retrieve undisturbed soil and rock samples for testing.
Products properties LEANOMS
For casing drilling in typical ground conditions, Odex Casing System is the most cost-effective options. They are particularly well-liked by drilling contractors for shallow micro-piling work, casing in water and geothermal wells, and medium-sized grouting holes for buildings,
dams, harbor projects, and geothermal wells. The clever reaming wing makes it possible to retrieve and reuse the bit. Odex Casing System is perfect for drilling small holes in uniform overburden because of its great benefits, such as its straightforward design, simple controls, retrievable drilling equipment, extended service life, and high quality. Odex Casing System has drilling properties similar to those of the DTH hammer drilling technique, such as:
1. Cuttings are removed quickly;
2. High penetration rate, particularly in basalt and other difficult rock formations;
3. simple groundwater and soil sample while drilling;
4. Possibility of measuring yield estimation at chosen formation depth;
5. Favorable in formations that are not well-consolidated and have a high risk of collapsing (this is probably the most important feature).
Odex (Overburden Drilling System with Excentric drilling) casing system is a drilling technology used in situations where there is loose overburden or unstable ground conditions, such as in mining, construction, and geotechnical exploration.
Products classification LEANOMS
ODEX casing systems are typically used in geotechnical and environmental drilling applications where a borehole needs to be drilled through unstable or difficult-to-drill formations. The ODEX casing system is designed to provide increased borehole stability and prevent the borehole from collapsing.
ODEX casing systems are used in drilling operations to prevent fluid loss and stabilize the wellbore. They are classified based on their design and functionality. Here are some common classifications of eccentric casing systems:
Conventional Casing System: This system is the most basic type of ODEX casing system. It consists of a single eccentric float shoe and a casing string. The float shoe is positioned at the bottom of the casing string and is designed to guide the casing to the center of the wellbore.
Multiple ODEX Casing System: This system consists of multiple eccentric float shoes and casing strings. The float shoes are placed at different intervals in the casing string to prevent fluid loss and stabilize the wellbore.
Single Joint ODEX Casing System: This system consists of a single joint of casing with an eccentric float shoe attached to it. The float shoe is designed to guide the casing to the center of the wellbore.
Multi-Stage ODEX Casing System: This system is used in complex drilling operations where multiple casing strings are required. It consists of multiple eccentric float shoes placed at different intervals in each casing string to prevent fluid loss and stabilize the wellbore.
Reaming ODEX Casing System: This system is used to enlarge the wellbore. It consists of a casing string with a reaming tool attached to the bottom. The tool is designed to ream the wellbore and create an eccentric annulus between the casing and the wellbore wall.
Reverse Circulation ODEX Casing System: This system is used in drilling operations where large volumes of fluid need to be circulated. It consists of a casing string with an eccentric float shoe attached to the bottom. The float shoe is designed to create a reverse flow of fluid up the annulus, which is then circulated back down the drill pipe.
