Презентация на тему по промысловой геофизике на тему MWD and LWD

functions and system components work of Measurement While Drilling

(MWD) and Logging While Drilling (LWD).

На этой лекции Вы изучите основные функции и работу системных компонентов «измерения во время бурения» и «каротажа во время бурения».

type of measurements does MWD provide that LWD does

not?
Tell all the correct answers.

a. Formation measurements
b. Drilling mechanics
c. Survey measurements

Correct answers:
b. Drilling mechanics
c. Survey measurements

a term used to describe drilling related measurements made

down hole and transmitted to the surface while drilling a well.

in MWD tools and some of the results can

be transmitted digitally to surface using mud-pulse telemetry.

transmitting LWD and MWD data acquired downhole to the

surface, using pressure pulses in the mud system. The same telemetry system is used to transmit commands from the surface.

of taking directional surveys in real time. The tool

uses accelerometers and magnetometers to measure the inclination and azimuth of the wellbore at a location, and they then transmit that information to the surface.
Also MWD tools contain an internal gamma ray sensor.

surveys is in directional drilling. For the directional driller

to steer the well towards a target zone, he must know where the well is going, and what the effects of his steering efforts are.

information about the conditions at the drill bit. This

may include:
Rate of penetration
Rotational speed of the drill string
Smoothness of that rotation
Type and severity of any downhole vibration
Downhole temperature
Torque and weight on bit, measured near the drill bit
Use of this information can allow the operator to drill the well more efficiently, and to ensure that the MWD tool and any other downhole tools are operated within their technical specifications to prevent tool failure.

part of the bottom hole assembly (BHA).

results to the surface via typically a drilling mud pulser, while LWD tools are still in the borehole, which is called "real-time data". Complete measurement results can be downloaded from LWD tools after they are pulled out of hole, which is called "memory data".

LOGGING WHILE DRILLING

Shakarim Kurmanbayev

originally developed to partially or completely replace wireline logging.

Over the years, more of the measurements have been made available in LWD. Certain new measurements are also development in LWD only.
