Abstract:

According to the operating principles of array lateral electrode arrays in horizontal wells and highly deviated wells, electric field is studied by using multiple electric field superposition method, and the 3D finite element method is employed to simulate electric field distribution of various points, and then electric field linear superposition principles are used to get the array lateral logging response. Based on the computer simulation, five array lateral logging curve radial investigation depths are obtained. The array lateral radial detection depth is smaller than the deep lateral detection depth. The effect of well deviation and variation of depth of invasion on log response in the 3D formation model is examined; and the characteristics of array lateral log response in horizontal wells and highly deviated wells is analyzed. The simulation results are as follows: well deviation has a small impact on array lateral log response when the well deviation is less than 15°, and correction of well deflection is not necessary; while the well deviation must be corrected when the horizontal well deviation is more than 60° in a highly deviated well due to a greater difference of array lateral log response between highly deviated wells and vertical wells.

Key words: horizontal/highly deviated well, array lateral, finite element, log response
