Abstract: The DXX68C29 [KG*4]well is located in Xin 68 block three East high position of a structure of a key well. The well didnt normal product because of serious sanding in 27 July 2011, influenced the capacity up to 15.4 m³. In view of the well casing channeling long well section, the hole diameter change after the casing sealing channeling and the contradiction of large of inclination change, the 40 arm caliper was used on the well casing diameter analysis, selected suitable control sand technology. The method solved the contradiction of the well which could not be normal production because of the sanding. The well had worked 170 days continuously and had produced oil 1 179.9 m³ accumulatively after opened in 4 August 2011. A new train of thought was provided to solve similar well control sand. The 40 arm caliper structure, measuring principle and technical index were introduced. A new idea and technical were provided to solve the problem of unconsolidated reservoir control sand, and analyzed of the field application of the instrument effect through field application.
