Abstract

Abstract:

This paper mainly discussed the abnormal responses of amplitude attenuation resistivity and phase shift resistivity
detected by logging-while-drilling resistivity instruments in the borehole of large deviation and horizontal wells. Combining
with the simulation results of EMF of the LWD resistivity responding in borehole environment，the paperwe analysed the major
characteristics and reasons of abnormal corresponding of these two kinds of resistivity. And then，we listed the curves of the
LWD amplitude attenuation and phase shift resistivity of three typical wells of Bozhong area of CNOOC company，which were
logged by EWR-Phase 4 of Halliburton International company，The amplitude resistivity and phase shift resistivity of this three
wellsto illustrate a typical unusual changes in the curve morphology. With discussion on lithology of the formation，permeability
of reservoir，mud invasion，drilling velocity（ROP）and environment of borehole，the curves reading range and variation
trend are examined for the X-Shallow，shallow，mediate and deep resistivity. In the endFinally，the paperwe summarizes that
the abnormal corresponding types，such as Zorro effect，lace curtain effect and polarization angle effect，are most frequently
encountered in the high angle and horizontal wells logged by EWR – Phase 4 tools.

Key words: LWD；EWR &ndash, Phase 4；Zorro effect；lace curtain effect；large deviation well
