Development of technology of cluster well drilling preventing borehole collision

摘要

Measures preventing collision of boreholes of directional wells cluster drilling are critical for successful cluster drilling. Additional wells are designed and drilled at some oil and gas fields, such as Neft Dashlary, Guneshli. Gum-deniz, Pirallakhi. Usually trajectory of each planned well intersects with the boreholes of 3-5 development wells on the horizontal plane, and this increases risk of collision. Risk of boreholes collision depends on many geological and engineering factors.
