| Abstract: | The rubber packer with leather cup seals screen pot annular space, low-viscosity solution is sand laden fluid and proper sand-carrying ratio is used in internal casing low-pressure gravel squeeze packing sand control technology. Packing gravel with certain grain size into screen pot annular space, bullet hole and near wellbore zone controls sand flow to ensure well normal stable production, prolong pump-repair cycle and enhance production time ratio. The pilot test of this technology is carried out in six wells of Dongxin oilfield, construction successful ratio and effectiveness are 100%, cumulative oil increment in six months is 16312.7t. |
