Abstract In this paper, by in-depth geological research of Kalamkas Oilfield in Central Asia, the geological body has been re-ascertained; combined with fine study of reservoir engineering, based on the understanding of the distribution of remaining oil, horizontal wells have been given full play to stabilizing oil production and controlling water cut, reducing the producing pressure drop, improving well productivity and other advantages, and the development and deployment has been optimized; horizontal wells have been applied to solve problems such as old well casing damages, shutting down wells, low-productivity and lowefficiency wells, and high water cut wells to improve the utilization rate of old wells; through separate layer system improved injection production pattern, adjustment wells have been optimized and deployed, and part measures wells have been preferably selected to tap the residual oil, improve the degree of reserves control, realize the stabilization of oil production and control of water cut in an old oilfield, and further improve the development effects.

Key words： Oil production stabilization and water cut control Remaining oil Flooding pattern improvement Horizontal well Sidetracking horizontal well Countermeasure
