Fig. 2 and 3 shows down-hole of the present invention integrated pipeline part and has certain flexiblely, and down-hole integrated pipeline part comprises circular body 18, is provided with passage in circular body 18: supervisor 16 and looped pipeline (being also production fluid pipe) 17.Be responsible for 16 one end and be connected with ground high voltage power supervisor 15 at well head, the other end provides the port of action edge to be connected with giving the piston 36 in underground hydraulic plunger pump 19 in pit shaft.Looped pipeline 17 one end are connected with ground high voltage power looped pipeline 8 at well head, and the other end provides the port of lower action edge to be connected with giving the piston 36 in underground hydraulic plunger pump 19 in pit shaft.Be appreciated that the needs for power or signal transmission are provided to down-hole Other Instruments or device, other passage or pipeline also can be set in body 18, other passage or pipeline are not limited to hollow, can be solid, as cable etc.The material of supervisor 16 and looped pipeline 17 preferably adopts has certain flexible steel or plastics etc., to guarantee, after moulding, can be wrapped on rod.
Down-hole of the present invention integrated pipeline part is made by the packaging technology of extrusion modling, body 18 can adopt the material similarly as polyurethane, nylon, neoprene etc. with certain ductility and moulding applicable extrusion modling, during manufacture, first at many initial positions of passage, simply locate, then just can adopt monolithic extruded way integrated system to be carried out to the production of mass, to make body 18 encapsulate described passage (supervisor 16 and looped pipeline 17).Whole manufacturing process is comparatively simple, and cost is lower.The solid-state plastic material of extrusion modling can provide good insulation and insulation blocking to the passage in package system.Supervisor 16 and looped pipeline 17 profiles adopt round design can be suitable for better the on-the-spot requirement of using, its ground transport and deposit completely and can be solved by domestic coiled tubing technology equipment existing, comparative maturity, can accomplish the general of corollary equipment facility, and without carrying out independent Design and manufacture, the user cost and the research and development that greatly reduce user drop into.
Fig. 4 and Fig. 5 show underground hydraulic plunger pump 19 of the present invention.In the space of underground hydraulic plunger pump 19 in sleeve pipe 29.Underground hydraulic plunger pump 19 comprises working barrel 30, thereby lateral partitions 45 is arranged on the middle and upper part of working barrel 30 is divided into upper and lower two cavitys by working barrel, upper traveling valve 33 is positioned at upper cavity, and lower travelling valve 39 is positioned at lower cavity, and standing valve 43 is fixed on the bottom of working barrel 30.Upper traveling valve 33 is connected by hollow piston rod 36 with lower travelling valve 39, thereby the valve chamber of the valve chamber of upper traveling valve 33 and lower travelling valve 39 is communicated with, and has so just formed the dual-piston structure that can move up and down in working barrel 30.The upper traveling valve seat 34 of upper traveling valve 33 is equivalent to upper piston, and between upper traveling valve seat 34 and dividing plate 45, has formed upper traveling valve 33 lower chamber 35; The valve seat 40 that moves about under lower travelling valve 39 is equivalent to lower piston, and under move about and between valve seat 40 and dividing plate 45, formed time travelling valve 39 upper chamber 37.Fluid Sealing between hollow piston rod 36 and dividing plate.Valve in the present invention and common oil well pump travelling valve used is basic identical, here its structure is repeated no more.
Above lateral partitions 45, on the inwall of working barrel 30, be provided with fluid passage 46.The top of working barrel 30 has up power port and descending power port, and up power port is communicated with the supervisor 16 of down-hole integrated pipeline part, and fluid can pass in and out upper traveling valve 33 lower chamber 35 by up power port, fluid passage 46.Descending power port is communicated with the looped pipeline 17 of down-hole integrated pipeline part, and fluid can be by descending power port turnover upper traveling valve 33 upper chamber 31.
In Fig. 4, the piston 36 of underground hydraulic plunger pump 19 is in up stroke working state, and in Fig. 5, piston 36 is in down stroke working state.Below in conjunction with attached Figure 4 and 5, describe up stroke and the down stroke working procedure of underground hydraulic plunger pump 19 in detail.
Up stroke:
As shown in Figure 4, when the hydraulic cylinder piston 4 in Fig. 1 is transported merit to the left, highly pressurised liquid in the outer chamber 3 of oil hydraulic cylinder left side (can be high pressure oil, also can be down-hole production fluid (oil water mixture), if gas well, also can be the Separation of Water after air-water separation) through ground high voltage power supervisor 15, fluid passage 46 on the supervisor 16 of down-hole integrated pipeline part and the inwall of working barrel 30 enters the lower chamber 35 of the moving valve seat 34 of underground hydraulic plunger pump 19 middle and upper reaches, when pressure acquires a certain degree, because the pressure of the upper chamber 31 of upper traveling valve seat 34 is less than the pressure of the lower chamber 35 of upper traveling valve seat, upper traveling valve 33 can move upward under differential pressure action, and drive lower travelling valve 36 up by hollow piston rod 36, now, lower travelling valve 39 is in closed condition (valve ball seat under move about on valve seat 40), liquid in lower travelling valve 39 upper chamber 37 is squeezed, the central passage entering in lower travelling valve 39 and in hollow piston rod 36 by the outage 38 of lower travelling valve flow in upper traveling valve 33, and thereby the valve ball that backs down upper traveling valve 33 makes upper traveling valve 33 in opening state, lower travelling valve 39 upper chamber 37 are just communicated with upper traveling valve 33 upper chamber 31, liquid in two chambers just enters in the looped pipeline 17 of down-hole integrated pipeline part along with the up of hollow piston rod 36, and be finally lifted to ground, complete the discharge opeing process of underground hydraulic plunger pump 19.In this process, because lower travelling valve 39 is all the time in closed condition, the pressure of standing valve 43 upper chamber 41 can reduce formation negative pressure gradually along with moving upward of piston 36, between working barrel 30 and sleeve pipe 29, the interior liquid of annular space will upwards back down the valve ball of standing valve 43, liquid in annular space enters in standing valve 43 and enters in upper chamber 41 by outage 42, completes the imbibition process of standing valve 43 upper chamber 41.
Down stroke:
As shown in Figure 5, when the hydraulic cylinder piston 4 in Fig. 1 moves to the right, highly pressurised liquid in oil hydraulic cylinder right side outer chamber 7 (is generally down-hole production fluid, if gas well, can be the Separation of Water after air-water separation) through ground high voltage power looped pipeline 8, the looped pipeline 17 of down-hole integrated pipeline part enters in moving valve 33 upper chamber 31 of underground hydraulic plunger pump 19 middle and upper reaches, upper traveling valve 33 and standing valve 43 are in closed condition, therefore upper traveling valve 33 upper chamber 31 internal pressures rise, and liquid in upper traveling valve 33 lower chamber 35 is because the power that loses ground pressure source provides, pressure reduces gradually, the pressure of upper traveling valve 33 upper chamber 31 is greater than the pressure of upper traveling valve 33 lower chamber 35, upper traveling valve 33 and lower travelling valve 39 move downward under differential pressure action, now, standing valve 43 is again in closed condition, liquid in standing valve 43 upper chamber 41 is squeezed, under the effect of pressure, the valve ball of lower travelling valve 39 can be backed down and make lower travelling valve 39 in open mode, liquid in standing valve 43 upper chamber 41 will enter in lower travelling valve 39 and enter upper chamber 37 by outage 38, complete the transfer of liquid from imbibition chamber to emptying chamber.
