| Abstract:Expandable tubular technology presents a new and unique challenge to the drilling industry, which can solve the problem of diameter shrinkage in well cementation and reduce the construction cost with good environmental protection effect and good future prospect in geological exploration. Experiments of expansion force were made based on the theoretical formula. By the comparison between experimental data and theoretical results, reasonable theoretical formula was chosen; the feasibility of expandable tubular using in geological exploration was analyzed; the expansion friction was reduced by lubrication measures to lower the expansion force and the lubrication effect were analyzed in theory. |
