MWD / LWD

 

MWD / LWD is crucial to accurate trajectory control, formation evaluation, geo-steering, increased drilling efficiency, hazard avoidance, and rig safety. HILONG’s MWD / LWD system is designed to acquire accurate, real-time downhole data with minimum impact on drilling operations. 

　　　

　　

?HTHP MWD

 

Our modular downhole assembly of MWD system includes electronics, directional sensors, pulsers and battery packs. The probe contains industry standard triaxial magnetometers and inclinometers and control electronics which allow full directional survey and steering operations over the complete inclination range of 0-180º. The MWD tool is programmable both on surface and down-hole in order to provide the following features:

 

　：　

 

 

 

?Positive Pulser powered by a downhole battery packs, at up to 1.5 bit/second.

 

 

?Rugged system design with a convenient drop-in replacement advantage and feature. Fully wireline retrievable and repeatable.

 

 

 

?Low Battery usage, highly efficient circuitry allows operation down to 20 V while extending battery life up to 400 hours per battery pack (800 hours for dual battery packs).

 

 

?Patented non-Bladder (or Bellows) design allows the temp range up to 175°C (347°F) and pressure range up to 22,500psi.

 

 

?Full directional survey capability with either computed or raw survey data transmitted. Raw survey data is used where correction of drill string magnetic interference is being applied.

 

 

?Transmission of survey quality parameters such as local magnetic field.

 

 

?Choice of either standard or fast tool face updates. In fast update mode the tool monitors the rate of change of tool face and adjusts the update rate accordingly and automatically. Thus tool face is transmitted every few seconds when tool face is being set but, once set, the tool converts into energy saving mode until such time as tool face variation is seen to exceed a pre-set limit.

 

 

?Automatic switching between magnetic and gravity tool face updates. The tool is set to convert from magnetic to gravity tool face updates when the well inclination exceeds the default value of 3º (this value can be changed if specially required by the customer).

 

 

?The surface computer system converts the information from down-hole into various displays of azimuth, inclination and tool-face. The MWD engineer can chose between simple text display of recent survey and steering information or can opt for a graphical display which also shows gamma ray logging data if this option is in use.

 

 

?Rig Floor Display which shows the most recent survey and a historical display of steering information. Surveys can be stored in either ASCII or common (DBF) database format for export to other directional drilling software packages. Historical tool face information is stored in a log file for further analysis if required. 

 

 

 

?LWD

 

LWD survey equipment (Logging while drilling), which is designed to accommodate the need for continuous taking the survey of geological parameter combined with path parameter during drilling operation. Real time and recorded mode are available at well site for accurate survey of steering data, gamma-ray (focus gamma) and resistivity. So, it is also able to continuously monitor & forecast the potential changes of formation while drilling. The capacity of geo-steering technology are used to locate reservoirs, identify gas / oil or oil / water contact bound, effectively place and keep horizontal wellbore within a formation boundary, and interactively steer to and through the optimum sections of a reservoirs. 式

 

 

 

Gamma ray tool offers a rugged and highly efficient scintillation type detector assembly that seamlessly integrates with our MWD system to provide real-time gamma ray feedback on the surrounding formation. This facilitates correlation with the API standard for more accurate geo-steering by configuring the MWD to transmit supplemental gamma data in rotating mode. The resulting high-resolution data is captured by ACE memory for surface download. 

 

Resistivity can be configured in a variety of ways depending on your information requirements, BHA design and well economics. Real-time Date while drilling are typically made within hours of drilling through zones when minimal formation damage, alteration, or formation fluid displacement has occurred. In areas with difficult drilling conditions, LWD can be used to avoid time-wasting conditioning trips or expensive pipe-conveyed logging operations. 

 

 

LWD (Formation evaluation) measurements can be used in deviated and/or horizontal wells to geologically steer a well for maximum formation exposure in the productive zone of the reservoir (GEOSTEERING).

Downhole Motor 

 

With a full range of tool diameters-from 2-7/8” to 11-1/4” – as well as input and output characteristics, housings, and stabilizer, HILONG performance motor can be configured to meet drilling requirements for steerability, build up rate, torque, bit speed, flow rates, and string rotation. 

HILONG performance motor is a kind of power tool that transforms the pressure of liquid to mechanical energy in the downhole. When the power liquid flows into the screw motor, pressure difference will be produced between the inlet and outlet of the motor, then the pressure difference drives the rotor rotating of planetary motion round the stator, and provides running torque and speed to the drill bit while the drill pipe is not rotating during work process, thus the drilling process is being performed. 

We also provide innovative solutions to a variety of drilling motor problems for a full range of applications including short and medium radius work and performance drilling in standard and elevated temperatures

The advantages of HILONG performance motors: 

 

?Safety Catch Assembly is available for full motor size range.

 

?Suitable for both water/oil base drilling fluid.

    

?High torque, excellent performance on penetration rate. 

    

?ERT pre-contoured stator Downhole motor is available for all motor size.

    

?Temp range up to 150°C (302°F) and Pressure range 20,000 psi.

    Long downhole lifetime.
