Description

Sand well layer circulation is more taken the sand extracting device of oil
Technical field:
The utility model relate to the extracting device of oil that uses on a kind of field produces, particularly sand well more layer circulation take the sand extracting device of oil.
Background technology:
Forcing to take the sand oil recovery under the high sand content situation of output liquid mainly exists sand holddown, sand-covered pump, sand to bury oil reservoir.Measure at sand well at present has sand control and takes the sand oil recovery, and simple sand control measure must cause oil well productivity to descend, and along with the prolongation of sand production history, sand controlling result descends in addition, causes oil recovery difficult.
Technical scheme
The utility model purpose be to provide sand well more layer circulation take the sand extracting device of oil, it buries oil reservoir three aspects and starts with from solving sand holddown, sand-covered pump, sand, forms a kind of pressure that is applicable to that height contains sand and takes the sand oil recovery technique.
The utility model purpose is to realize like this, it is by hollow foot piece (1), floating ring is got over pump (2), hollow rod (3), oil pipe (4), sleeve pipe (5), drain pipe (6), enter pipe (7), re-injection pump (8), outer defeated pipe (9), separate diversion cans (10), heater (11), sediment outflow pipe (12), well head (13) is formed, hollow from bottom to up foot piece (1) is got over pump (2) with floating ring in sleeve pipe (5), oil pipe (4) connects, hollow rod (3) one ends are got over pump (2) with floating ring and are connected in oil pipe (4), the other end with enter pipe (7) and be connected, oil pipe (4) top is well head (13), drain pipe (6) one terminates on the well head (13), the other end is connected on and separates on the diversion cans (10), enter re-injection pump (8) is arranged on the pipe (7), one terminates at and separates on the diversion cans (10), the other end is connected on the well head (13), defeated pipe (9) outside separation diversion cans (10) top is, the bottom is sediment outflow pipe (12), separates the interior having heaters of diversion cans (10) (11).
Down-hole pump: adopt the rod-type floating ring to get over pump, guarantee that at first down-hole pump can adapt to high sand content, can under the condition of no any sand control measure, work, thoroughly solve the problem of sand holddown, provide circulating fluid to cross pump channel simultaneously;
Down-hole string and roofbolt: substitute common bar with hollow rod, pump is hung the position near the oil reservoir upper bound, and pump plunger is hung hollow foot piece down, reaches the oil reservoir bottom or passes through oil reservoir with hollow foot piece.Its objective is part is sent under the oil reservoir through the output liquid of ground desanding processing, the full pit shaft liquid that causes scope can reach under the oil reservoir circulates, increase in the pump well-sinking and the flow velocity of upper aq in the oil pipe on the pump, reduce pulsation, effectively strengthen system-wide prop-carrying capacity, solve the problem that sand buries oil reservoir and sand-covered pump simultaneously;
Ground ancillary facility: establish sedimentation diversion cans and flow-controllable re-injection pump, supporting heating and lagging facility at well head.Output liquid enters the sedimentation diversion cans after going out well, reduces through heating back viscosity, major part is contained the sand sedimentation separation, outside the regular drain tank of sand.Output liquid can reduce the influence of sand to flow process through entering the station behind the sand setting.Output liquid after the re-injection pump of flow-controllable is handled the part sand setting injects shaft bottom with certain flow by hollow stem according to stratum output liquid measure situation, and the circulation of realization liquid forces to take sand.The heat of ground heater can be carried in the pit shaft, realizes the pit shaft heating, solves the problem of heavy crude heat extraction and thin oil wax deposition.
Hollow from bottom to up foot piece is got over pump with floating ring to the utility model in sleeve pipe, oil pipe is connected owing to having adopted, hollow rod one end is got over pump with floating ring and is connected in oil pipe, the other end with enter pipe and be connected, oil pipe top is well head, drain pipe one terminates on the well head, the other end is connected on and separates on the diversion cans, and entering has the re-injection pump on the pipe, and one terminates at and separates on the diversion cans, the other end is connected on the well head, defeated pipe outside separation diversion cans top is, the bottom is the sediment outflow pipe, separates having heaters in the diversion cans.Thereby thoroughly solve the sand holddown, solve the problem that sand buries oil reservoir and sand-covered pump simultaneously; The circulation of realization liquid forces to take sand.The heat of ground heater can be carried in the pit shaft, realizes the pit shaft heating, solves the problem of heavy crude heat extraction and thin oil wax deposition.Be well suited for field popularization application.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment:
As shown in the figure, the utility model is by hollow foot piece 1, floating ring is got over pump 2, hollow rod 3, oil pipe 4, sleeve pipe 5, drain pipe 6, enter pipe 7, re-injection pump 8, outer defeated pipe 9, separate diversion cans 10, heater 11, sediment outflow pipe 12, well head 13 is formed, hollow from bottom to up foot piece 1 is got over pump 2 with floating ring in sleeve pipe 5, oil pipe 4 connects, hollow rod 3 one ends are got over pump 2 with floating ring and are connected in oil pipe 4, the other end with enter pipe and 7 be connected, oil pipe 4 tops are well heads 13, drain pipe 6 one terminates on the well head 13, the other end is connected on and separates on the diversion cans 10, enter on the pipe 7 re-injection pump 8 is arranged, one terminates at and separates on the diversion cans 10, the other end is connected on the well head 13, defeated pipe 9 outside separation diversion cans 10 tops are, the bottom is a sediment outflow pipe 12, separates having heaters 11 in the diversion cans 10.
