COMPLETION TECHNOLOGY OF TAI 4 PING1 WELL

In order to enhance recovery ratio and single well deliverability,improve exploitation effect of oilfield,horizontal well produce experiment were developed.In view of geology circumstance of first horizontal well Tai4 Ping1 well,compared several produce scheme,optimized perforated completion with ?139.7 mm casing,and select tube transport and near equilibrium pressure perforation technology-use 89 gun and 89-Ⅲ bomb,SPF is 16 and down phase is 180°with 4 row of hole,treated water of this fault was used as flushing and perforating fluid.To avoid the lost item down to horizontal well section,developed string composed of Y421 packer,KHT connecting tripping device and decompression ball seat.Provide experiment for drilling horizontal well of sandstone reservoir in Huabei Oilfield.
