Logging while drilling technology is to expand the application of multi-parameters and high performance of the LWD system, which is mainly used in adopting conventional wireline logging and drill pipe conveyed logging horizontal well, large displacement well and complex well logging which have greater risk or not well logged; running in the hole together with well drilling tool on site operation, allowed drill tools rotation and circulated drilling fluid. This technology has the advantages of rapid operation, security and good quality logging curve, can avoid sticking, damage together and such downhole risks by using conventional logging cable or pipe conveyed logging.
Logging while drilling is not affected by the limitation of well depth and well deviation, and can be safely run into the wells;
LWD adopts pump opening and rotating drilling logging tools to avoid downhole accidents, such as sticking, etc.;
Its logging principle and time is different from conventional logging, and logging curve is more accurate and reliable;
Logging projects have the features of flexible selection, and can increase the measurement project according to the requirements of Party A;
Well logging ways are various, and can implement by taking the measurement while drilling and testing;
Logging is equivalent to a wiper trip operation, and can reduce the well completion operation time.
Main Module of the Logging Tools
Nature gamma and resistivity logging while drilling;
Neutron density and porosity logging while drilling;
High resolution resistivity imaging logging while drilling;
Acoustic logging while drilling;
NMR logging while drilling;
Formation pressure logging while drilling;
Azimuthal resistivity logging while drilling.
Application Case
Logging while drilling technology has solved the logging problems of complex wells, horizontal wells, etc., and gets unanimous approval from the customers.
