Abstract: Sand discharging technology is a new technology for sand production reservoir.This technology take high pressure water as power fluid, mixing fluid can be taken to the ground by hydraulic jet pump, which won’t form barriers to oil reservoir and formation won’t be plugged the second time.This technology can also make plug removal, prevent damage to formation by mechanical sand control and chemical sand control.The technology has been used in 4 wells of Shangnan Oilfield of Shengli, and investment is less but production is high, so it will be used widely.
