During application, strength of the guide is higher than that of the rod body. Matched guide specification shall be selected based on well conditions. Take Φ25, 28, 36 and 38 as example.

18. Basis of Directional Downhole Guide
The basis for running in guides are determined based on well depth and structure, especially the overall angle change rate (borehole curvature or dogleg angle).

19. Basis of Directional Downhole Guide
1. Whole well centralizing, centralizing on both ends of guide required
Vertical section: 1 centralizer is placed for each rod below the polish rod, and provided with limit coupling;
Whipstocking section, deviated section: 2 centralizers are placed for each sucker rod (with 1 in the middle), and provided with limit coupling.

2. Precautions
1) For running in at site, depth shall be relatively accurate (measurement of sucker rod must be precise), and the max. error shall not exceed 3m;
2) Screw-on shall be in place to avoid rework caused by backoff.
