          Abstract:
          In the process of oil exploration and development, some boreholes show a corkscrew shape due to the influence of drilling technology. The corkscrew borehole will affect the well logs and the log data will display fluctuations, which causes trouble to the calculation of reservoir parameters and log interpretation. Analyzed is the influence of corkscrew borehole on different logging curves, such as compensated density log and neutron log, electrical log, acoustic log, dualinduction log and array induction log, etc. Based on the fast Fourier transform (FFT) spectrum analysis on the well logs, we use a corresponding lowpass filter for process the log data filtering processing. After frequency domain filtering correction, the influence of corkscrew borehole on the logging curves has been remarkably weakened, and the log curves have been optimized. Practical application in well ZJ28 of Zhenjing oilfield shows that this correction method is effective, the influence of corkscrew borehole on the log curves have been eliminated, and the processed log curves can correctly reflect formation physical properties.
