According to the structure of the dynamic pipe oil extraction device, a wellhead cross joint is installed at the top of an oil well casing pipe; a packing box is arranged above the wellhead cross joint; a pumping rod penetrates the packing box and the wellhead cross joint to be connected with a wellhead sealing plunger; a Christmas tree is connected with the pumping rod; the top of a hollow pipe is connected to the wellhead sealing plunger; the lower end of the hollow pipe is connected with a plunger which is arranged above an oil well pump; the middle of the hollow pipe is provided with a rolling wheel type centralizer; the oil well pump is arranged inside a casing pipe; the upper end inside the oil well pump is provided with the upper plunger; the upper plunger and a lower plunger are connected through a connecting hollow rod; a hole is formed in the middle of the connecting hollow rod; a hydraulic anchor is arranged outside the upper portion of the oil well pump; the bottom of the oil well pump is provided with a fixed valve; a tail pipe is connected with the fixed valve.
Description
Technical field: the utility model relates to oil recovery Lifting Technique, especially a kind of moving pipe extracting device of oil.
Background technology: existing rod-pumped well oil recovery technique, in oil well casing, be first lowered to tail pipe, deep-well oil pump, oil pipe, be lowered to again piston and sucker rod, by moving up and down of pumping unit horsehead, drive the piston movement under sucker rod, the most oily stream is lifted to ground, such technical matters complexity, and expense is high.
Summary of the invention: the purpose of this utility model is to provide the moving pipe extracting device of oil of one simple in structure, it has overcome complex structure in current technology, the shortcoming that cost is high, the purpose of this utility model is to realize like this, it is by polished rod, packing box, well head four-way, wellhead sealing plunger, hollow section, roller-type centralizer, upper plug, Hydraulic anchor, connect through rod, lower piston, oil well pump, standing valve, tail pipe, production tree, sleeve pipe is formed by connecting, on the top of oil well casing, well head four-way is installed, there is packing box top at well head four-way, sucker rod is connected with wellhead sealing plunger with well head four-way through packing box, production tree is connected with sucker rod, the top of hollow section is connected on wellhead sealing plunger, and its lower end is connected with pump upper plug, middle-end at hollow section is installed with roller-type centralizer, oil well pump is arranged in sleeve pipe, and there is upper plug the upper end in oil well pump, and upper plug connects by being connected through rod with bet match, and the centre that connects through rod is porose, there is Hydraulic anchor outside, top at oil well pump, the bottom of oil well pump is installed with standing valve, and tail pipe is connected with standing valve.
Method of work of the present utility model: oil pumper drive hollow section and upper plug, lower piston move up and down, formation oil stream sucks standing valve, lower piston, connection through rod, upper plug by tail pipe, enter hollow section, the external roller-type centralizer of hollow section prevents from producing friction with sleeve pipe; Oil stream, again by wellhead sealing plunger oil outlet, enters well head four-way and production tree, completes pumping lifting process.
Meaning of the present utility model is: the utility model replaces solid sucker rod band pump work with hollow section, and doubles as out oil flow channel.Under hollow section cornice pump, after projected depth, suppressing and set, is also to hollow pipe column pressure testing, then can produce after transferring stroke height of hollow stem.Feel uneasy a position, change place sets repeatedly.When operation, tear well head open, playing afterwards pipe can trip out in the lump together with centralizer, Hydraulic anchor, pump barrel, tail pipe etc., has simplified flow string, has reduced upkeep operation cost.
Brief description of the drawings: Fig. 1 is a kind of structural representation of moving pipe extracting device of oil, in figure 1, polished rod 2, packing box 3, well head four-way 4, wellhead sealing plunger 5, hollow section 6, roller-type centralizer 7, upper plug 8, Hydraulic anchor 9, connect through rod 10, lower piston 11, oil well pump 12, standing valve 13, tail pipe 14, production tree 15, sleeve pipe.
