In order to solve the problem of the rapid increase of water cut for horizontal wells in bottom water reservoirs, and traditional ICD and AICD intelligent water control technologies cannot meet the water control requirements in the entire development process, C-AICD water control technology was tested in a bottom water reservoir. C-AICD water control technology fully integrates the advantages of ICD and AICD water control technology. It can realize the wholelifewater control concept and process of “the flowofwater is restricted in the early stage, and the rise of water cut is inhibited in the later stage”. Combining with the permeability distribution of the horizontal section of the oil well, the spacer was used to separate the horizontal section and implement segmented water control, and the test achieved a certain water control effect in an oil field in the eastern of the South China Sea in China. When the C-AICD water cut technology well which construction position is lower was put into production, the water cut of the adjacent wells in the same layer was as high as 90%. The implementation of C-AICD technology wells has a low water cut period, and the water cut has risen to 90% after 8 months. C-AICD water control technology provides new technical means and ideas for long-term water control and stable production of horizontal wells in edge/bottom water reservoirs, and has important reference value.
