| Abstract:Based on the analysis on the technical difficulties of L-type CBM horizontal wells in Shanxi, the corresponding technical countermeasures are explored, 2 build-up guidance models of landing and horizontal sections are established to form the geo-steering technical process mainly in 4 aspects of marker beds division and correlation, stratigraphic dip calculation, geological modeling and real-time trajectory control for L-type CBM horizontal wells. The successful application of this technology in T-P05 well not only enriched the contents and methods of geo-steering technology for CBM horizontal wells, but also further verify its good feasibility and application prospect, this technology is worth promoting and applying in L-type CBM horizontal wells in Linfen block. |
