| Abstract: | ??Taking the separate zone production of well 21 Tieshan as an example,a separate zone production technique of using bayonet-tube packer and the appropriate downhole tool to separate the upper producing zone form the lower is introduced.The characteristic of the technique lies in taking tubing and casing annular space as the production passages respectively to achieve separate zone production.The present technique,with the merits of simple operation and small investment,is suitable for the wells with low H_2S content. |
