Description
Technical field
The present invention relates to a kind of probe, particularly a kind of probe for well logging during.
Background technology
With brill electromagnetic wave resistivity logging and Gamma logging are all most important methods in well logging during field.Resistivity logging while drilling well logging reflects the information of stratum media by the Amplitude Ratio of recording electromagnetic wave signal and phase difference, with the lithology of boring Gamma logging and to be determined by the gamma ray that Log Strata rock radiates stratum.Acceierometer sensor is mainly used in in the inclination measurement system of boring and continuous inclination measurement system, for measuring the gradient of drilling well.Pressure sensor is then used to measure the pressure in well system.
Current application be generally separately independently equipment with brill electromagnetic wave resistivity logging instrument and Gamma logging instrument.During operation, needs will to combine work with brill electromagnetic wave resistivity logging instrument and Gamma logging instrument, so not only make that the parts of machinery and electronics increase, instrument is longer, and add the fault rate of system.In addition, this drill-following natural gamma ray logger is generally only equipped with a gamma sensor, and occupy the center of drill collar, and the log response information obtained like this is the radioactive summation of Different Strata, and can not distinguish the interface of different lithology.Therefore, existing drill-following natural gamma ray logger can not catch the top cap rock of reservoir and the information of bottom cap rock in time, thus loses the best opportunity entering reservoir.
Summary of the invention
The object of the present invention is to provide a kind of probe, it is the probe of multifunctional all, can realize with several functions such as brill electromagnetic wave resistivity logging, Gamma logging, accelerometer well logging and pressure sensor well loggings simultaneously.
According to probe of the present invention, comprise electromagnetic resistivity measuring coil, gamma sensor, three axis accelerometer and pressure sensor, it is integrally formed in probe.
