Abstract
The utility model relates to a well completion and flow string of a horizontal well and overcomes the defect that the open hole packer of a horizontal section cannot effectively pack an oil-water layer because the diameters of the well are irregular in the well completion construction of the open hole sand control screen pipe of the existing horizontal well. A well completion string is fixedly installed at the horizontal well section in an open hole shaft. The stage collar, the casing nipple, the external packer I, the blind plate, the casing, the layered seal bore I, the upper screen pipe, the layered seal bore II, the casing nipple, the external packer II, the casing, the external packer III, the casing nipple, the layered seal bore III, the lower screen pipe, the well cleaning valve, the lower screen pipe and the guide shoe of the well completion string are sequentially and fixedly connected. An acid cleaning string, top-sealed bottom-open string, bottom-sealed top-open string or commingling string is installed in the well completion string. The utility model has the advantages that since the well completion technology of the horizontal well is combined with the late-stage oil production technology, the segmental sealing effect between the well completion string and the open hole shaft is improved, the bottom water coning is delayed and the goals of controlling water and increasing oil are realized.
