Description
The utility model relates to a kind of oil field underground equipment that is used for, the packing device when being specially adapted to the low pressure oil well hot-washing wax remover.
At present, the pumpingh well hot-washing wax remover is with the hot car washing group hot washing lotion to be injected annular space between oil pipe and the sleeve pipe from the oil well casing gate, up to the oil well pump intake, upwards returns ground from oil pipe again, reaches heat and washes purpose.Adopt this method, occur such problem easily: because hot washing lotion sinks to the shaft bottom, under the effect of hot car washing group pressure, hot washing lotion enters oil reservoir, polluted reservoir.Simultaneously also can increase the liquid emphasis amount of Pump Suction Nozzle, cause kill-job with the section of going into the well.Its as a result the lighter cause oil well output to descend, weight person's oil well can be killed by hot washing lotion, can not resume production.And use hot car washing group expense height, heat to wash short, heat of time and wash discharge capacity and do not reach heat to wash requirement, wax removal not thorough.
The purpose of this utility model is to overcome the weak point in the background technology, packing device when a kind of hot-washing wax remover is provided, it can stop hot washing lotion to enter oil reservoir effectively, prevents oil layer pollution, also can save hot car washing group high pressure well-flushing simultaneously, realize the purpose of low pressure water mixing hot-washing wax remover and viscosity reduction.
The purpose of this utility model is achieved in that tubing anchor fixed pattern heat washes packer, comprise that central tube, packing element, packing element support column, outer tube, ball-and-seat, oil gas enter hole, oil gas tap and hot washing lotion and enters the hole, the top connection at packer two ends and lower contact are connected with oil pipe is movable, be annular space between central tube and the packing element support column, the outer and packing element of packing element support column joins; Central tube is provided with outer tube outward, and outer tube inside is provided with the ball-and-seat group, and the outer tube bottom is provided with oil gas and enters the hole; The central tube upper end is provided with the oil gas tap and hot washing lotion enters the hole; The central tube bottom is provided with ball-and-seat, and anchoring device is equipped with in lower contact place.
The utlity model has simple in structurely, handling ease adopts this device can stop hot washing lotion to enter packer with the section of going into the well effectively, prevents oil layer pollution; Because hot washing lotion does not contact with oil reservoir, so the kill-job phenomenon can not occur, oil well heat is washed and can be resumed production very soon; Use this packer can utilize the existing water mixing flow process in well site to carry out well-flushing, realize low pressure water mixing hot-washing wax remover; Owing to be used with existing tubing anchor, can reduce the oil well pump loss of plunger stroke, improve pump efficiency; Adopt this device, during oil well production, oil gas can enter the above oil jacket annular space of packer by the packer interior annular space, and can make oil gas obtain separating, and also can carry out the producing fluid level monitoring simultaneously.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model structural representation;
Fig. 2 is four ball formula ball-and-seat structural representations.
Among the figure: 1-is warm, and washing lotion enters the hole, 2-oil gas tap, and the 3-central tube, 4-packing element support column, the 5-packing element, 6-ball-and-seat group, 7-oil gas enters the hole, 8-outer tube, 9-ball-and-seat.
Tubing anchor fixed pattern heat is washed packer and is comprised that central tube, packing element, packing element support column, outer tube, ball-and-seat, oil gas enter hole, oil gas tap and hot washing lotion and enters the hole, the top connection at packer two ends and lower contact are connected with oil pipe is movable, its improvements are: for annular space, the outer and packing element 5 of packing element support column joins between central tube 3 and the packing element support column 4; Central tube is provided with outer tube 8 outward, and outer tube 8 inside are provided with ball-and-seat group 6, and the outer tube bottom is provided with oil gas and enters hole 7; Central tube 3 upper ends are provided with oil gas tap 2 and hot washing lotion enters hole 1; The central tube bottom is provided with ball-and-seat 9, and anchoring device is equipped with in lower contact place.Ball-and-seat is the float-ball type structure, is made up of ball seat and ball float; The ball-and-seat group of outer tube 8 inside can be four ball formula ball-and-seats and constitutes (as shown in Figure 2), and anchoring device is equipped with in lower contact place.
The utility model is to be provided with the packing element support column in original compression packer inside, forms annular space between packing element support column and the central tube, and the middle and lower part of central tube is designed to the spline channel-type, is provided with four ball-and-seats, stops hot washing lotion downward; In the lower contact of central tube bottom, be provided with heat and wash ball-and-seat, prevent that hot washing lotion from entering the packer bottom; Packer top connection place is provided with heat and washes inlet opening, oil gas tap, and the outer tube of packing element bottom is provided with oil gas and enters the hole; Anchoring device also is equipped with in packer lower contact place, in order to the grappling oil pipe.
Duty behind the packer setting as seen from Figure 1, when the pumpingh well ordinary production, the overheated ball-and-seat 9 of washing of the oil circulation in the oil pipe upwards flows, and enters top oil pumping pump barrel, up to being drawn out of well head; The gas stream of oil sets annular space can enter hole 7 and be upward through ball seat by the oil gas on the outer tube of packing element bottom, enter the annular space between oil pipe and the support column, and portalling from the oil gas on packer top then 2 enters oil sets annular space.Guarantee that oil stream is up unimpeded, the sleeve pipe exhaust is unaffected, can also carry out the producing fluid level monitoring.
During hot-washing wax remover, hot washing lotion enters oil sets annular space by the well head sleeve gate and since packer stop that hot washing lotion can only enter packer inside by the hot washing lotion hole 1 and the oil gas tap 2 on packer top.Enter the hot washing lotion in hole 2, by the annular space between central tube and the sebific duct, the compressing ball float is sitting on the ball seat, and hot washing lotion can not be passed through.The hot washing lotion that enters hole 1 is downward by central tube, washes ball-and-seat 9 by heat and stops, and makes it can not enter the packer bottom.Be advanced into packer top pump barrel on hot washing lotion has only, wash under the pressure effect, upwards discharge well head, wash end up to heat in the draft and the heat of pump.After heat is washed end, when packer top liquid level is extracted into certain altitude by oil well pump, the head of liquid on oil sets annular space packer top is less than returning pressure on the oil reservoir of packer bottom, and heat washes ball-and-seat 9 and four ball ball-and-seat groups 6 are opened voluntarily, and oil well returns to normal production immediately.
