Under the current work-over engineering technical conditions, restoring original state is difficult. This will cause borehole deformation and well size reducing, even result in abandonment of the oil wells. In order to make well pattern perfect and improve utilization factor of oil wells, some renewable wells and sidetrack wells have to be drilled. Some of these wells can' t produce normally for sand production, using common gravel pack and sand control technique can' t solve this problem. So reverse circulation gravel pack and sand control technique is studied. Pilot test is done in three wells of Dongxin oilfield with 100% of successful ratio and effectiveness. Good result is a chieved with 49.8m3 of daily liquid production and 11.5t of oil production in early stage, 80.5% of composite water cut, 5871. Ot of cumulative incremental oil. Practice proves that this technique provide a new approach and thinking for sand control and tapping potential to improve effect in special-casing-configuration wells of the casing deformation well, the sidetrack well or the variable-casing-wall-thickness well.</em></p><p class='subject'><strong>关 键 词：</strong><a
