Movable flushing fluid purification device

Abstract

The invention relates to a movable flushing fluid purification device, and belongs to the technical field of oil field flushing fluid treatment devices. According to the movable flushing fluid purification device, flushing fluid is pumped into a sediment box via a flushing fluid inlet pipeline through a mud pump; after sediment in the sediment box, oil, water and mud in the flushing fluid are layered; oil grease on the uppermost layer is sucked into an oil storage box through an oil suction pump and an oil suction pipeline; the mud on the bottommost layer is discharged through the mud pump anda mud discharging pipeline; the flushing liquid after sediment enters a cyclone separator, and the residual mud and oil grease in the flushing liquid are removed through the cyclone separator; and the separated flushing liquid is atomized through an atomization device and then is sprayed into a coarse grain separating device. The characteristic that the affiliation condition of oil water is different from that of solid materials is used, when an oil and water mixture flows through a ceramsite layer, the flow speed and direction are forced to be changed ceaselessly, the probability that waterdrops collide and are gathered is improved, and small liquid drops are quickly gathered and settled, so that the dissolved oil grease in the flushing liquid is removed, and the flushing liquid is purified.

Description

technical field [0001] The invention relates to a movable well flushing fluid purification treatment device, which belongs to the technical field of oil field well flushing fluid treatment devices. Background technique [0002] In the research work of sand flushing and well washing in oilfields, hydraulic sand flushing has been widely used due to its simple process, complete cleaning of the well bottom, and large amount of sand flushing. This method is to use the pump truck to give the sand washing fluid a high flow rate, let the fast flowing sand washing fluid inject into the well, use hydraulic action to disperse the sand particles in the well, and then when the liquid flow returns to the oil well, the bottom of the well is washed The loose sand particles are taken out of the oil well by the carrying capacity of the liquid, so that the sand accumulation in the well is removed. In early sand flushing and well flushing operations, gravity sedimentation technology was widely...
