Drill Collar is manufactured from AISI 4145H modified quenched and tempered steel and is heat treated along its entire length for uniform toughness and durability. Strict metallurgical tests are performed per specifications to ensure that the heat treatment produces consistent and maximum hardness through the depth of the bar.

Landrill supplying drill collars in standard and spiralled from 3-1/8” OD up to 14” OD in accordance with API, NS-1 or DS-1 specifications.

Downhole motor is a positive displacement downhole power drilling tool, which is powered by drilling fluid and coverting fluid pressure into mechanical energy. Mud stream from the outlet of mud pump flows through a by-pass valve into the motor. This stream produces pressure loss between inlet and outlet of the motor to push the motor rotating around the stator’s axis, then transmits rotation speed and torque to the bit by universal shaft and drive shaft to implement the well operation.
LANDRILL can supply many types mud motor to meet clients’ different drilling condition.

Drilling jar is a downhole tool that delivers an axial impact load to the stuck point of a drill string. Jars are often the first line of defense against stuck pipe and can save operators from costly fishing and remedial operations by quickly “jarring” the string free.

Landrill can supply Hydraulic Drilling Jar & Double Acting Hydraulic-Mechanical Drilling Jar & Super Fishing Jar

The Shock absorber is used for reducing vibrations caused by hard formation drilling and keeping the drill bit firmly on the bottom, so that it helps to reduce drill string connection fatigue and prolong drill string life.

Non-magnetic Drill collars are made from Non-magnetic steel bars with low-strength by combining a proprietary chemical analysis and a rotary hammer forging process with low magnetic permeability excellent machine ability, it will not interfere with the specialized directional equipment and will enhance the performance of the drilling operation.

Non-mag drill collars function as housing for the MWD tools, while at the same time provide the weight for drillstring. non-mag drill collars are suitable for all types of drilling including straight and directional applications.

Each drill collar is fully inspected by internal inspection dept. All data obtained are recorded on the inspection certificate furnished with each drill collar. API monogram, serial number, OD, ID, type and size of connections are stamped on recessed mill flats.

Drill string valves stop fluid from flowing up the drill string often if the drill kicks with the bit off bottom.LANDRILL can supply premium quality Full opening safety valve(FOSV), Kelly valve, Inside blowout preventer(IBOP), Drop-in check valve, Float valve.

Features
1.Full-bore design effectively eliminates pressure drop and eddy currents and slows down solid particles in the fluid
flushing of valves;
2.Unique sealing design, so that the switching torque is greatly reduced;
3.Metal seals are made between the bonnet and the valve body, the valve plate and the valve seat ring;
4.Metal sealing surface spray (overlay) welding cemented carbide, with good wear resistance, corrosion resistance;
5.The seat ring is fixed by the fixed plate to maintain good stability;
6.The stem is equipped with an inverted sealing mechanism to facilitate the replacement of the stem sealing ring with pressure.

We have the following advantages with our Dissolvable frac plugs:
Completely Dissolvable: The plugs can dissolve completely in fluids.
Both Metal and Rubber Materials are Water-soluble: Dissolvable frac plug is made of dissolvable materials, including both metal and rubber components, which means the entire plug can be dissolved.
Controlled Dissolving Rates: The dissolving rate of the plug can be adjusted to meet different operational needs.
Very Low Residue: After dissolution, the dissolvable frac plugs leave no residual debris or fragments, reducing the need for clean-up after operation.
Full Range of Sizes Available: The plugs are available in various sizes and models, making it adaptable to different casing sizes and well depths.
Suitable for 3.5”-5.5” Casing Grades: The plugs can be used for various casing grades with diameters ranging from 3.5 inches to 5.5 inches.
Compatible with Different Water Mineralization Levels: The plugs are compatible with different water types and mineralization levels within well formations.
Compatible with Formation Temperature Range of 25℃-170℃: The plugs can be used within well formations ranging in temperature from 25°C to 170°C.
Offer Special Customization: While meeting basic requirements, the plugs can also be customized based on customer’s specific needs.

Choke manifold is the necessary equipment to control kick and implement pressure control technology of oil and gas wells. When the blowout preventer is closed, a certain casing pressure is controlled by opening and closing the throttle valve to maintain the bottom hole pressure slightly higher than the formation pressure, so as to prevent the formation fluid from flowing into the well further. In addition, choke manifold can be used to relieve pressure to realize soft shut in. When the pressure in the well rises to a certain limit, it is used to blowout to protect the wellhead. When the well pressure increases, the fluid in the well can be released to control the casing pressure by opening and closing the throttle valve (manual adjustable, hydraulic and fixed). When the casing pressure is very high, it can directly blow off through the gate valve.
