Abstract
The utility model discloses a continuous liquid draining device for oil testing in exploration well, comprising a base, a control cabinet, a brake, a motor, a speed reducer, a roller, a steel wire winding the roller, a lower fixed pulley, a support, an upper fixed pulley, a travel sensor, a movable pulley, a hanger, a slick rod, a well head, an oil pipe, an underground pump, an input coupling, a stopper and an output coupling. The utility model is characterized in that the control cabinet, the motor, the brake, the speed reducer, the roller, the lower fixed pulley and the support are arranged at the base; the upper fixed pulley and the travel sensor are arranged at the support; the movable pulley are connected with the hanger, the slick rod and the underground pump in order; the oil pipe is acidized fracturing integrated pipe. The utility model, adopting a reluctance motor, under the control of the control cabinet, drives the underground pump to carry on swabbing and testing oil. Therefore, the utility model has the advantages of continuous swabbing, accurate data, small labor intensity and environmental protection and can be mainly applied in the oil testing technology and other similar apllications.
Description
One, technical field
The utility model relates to the oil exploitation downhole operation equipment, particularly a kind of continuous liquid-discharging device for exploration well testing for oil.
Two, background technology
Oil exploitation formation testing method has tubing flow displacement, pumping, gaslift etc., the most frequently used is pumping, the pumping method comprises ground and underground installation, ground is with the tractor hoist source that is used as power, the wire rope that twines on cylinder rotation by installing on it and the cylinder connects the down-hole facility and moves both vertically up and down, finishes the pumping operation.The down-hole facility mainly is sucker rod and swab, connects sucker rod by the continuity of ground surface roller steel wire, connects the swab motion on the sucker rod, and liquid in the well is given rise to ground.The formation testing technology that this traditional method is oil exploitation contributes, but also exists following shortcoming or deficiency simultaneously: 1. the well head sealing is difficult, and well liquid often leaks to ground, causes environment pollution; 2. the swab life-span low, use the just wearing and tearing leakage of several days rubber, sometimes even well liquid can not be lifted to ground, lose swabbing action fully, have to trip out grape, more renew, reduce operating efficiency greatly, improve operating cost; 3. ground adopts tractor hoist to be used as power, and intensity was big during operating personnel worked in the continuous operation, and there is hidden danger in tired operation; 4. formation testing is adopted liquid owing to change swab, and personnel's fatigue etc. forces formation testing to adopt liquid and can not move continuously, and therefore some data that obtains are just inaccurate, causes the trouble of the inaccurate and follow-up work of oil in place calculating.
Three, summary of the invention
The purpose of this utility model provides a kind of improved continuous liquid-discharging device for exploration well testing for oil, and ground adopts motor to be used as power, and is controlled by controller; Well head adopts polished rod, and the sucker rod pump system is adopted in the down-hole, the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art, and the pumping serialization improves operating efficiency, to gather all information accurate effectively.
Continuous liquid-discharging device for exploration well testing for oil described in the utility model, comprise pedestal, switch board, brake, motor, reducer, cylinder and the wire rope that upward twines thereof, following fixed pulley, support, last fixed pulley, stroke sensor, movable pulley, polished rod eye, polished rod, well head, tubing string, down-hole pump, the input shaft coupling, brake and output shaft coupling, described switch board, motor and brake, reducer, cylinder, following fixed pulley and support are installed on the pedestal, described support is equipped with fixed pulley and stroke sensor, described movable pulley in turn with polished rod eye, polished rod is connected with down-hole pump, and tubing string is the acid fracturing integrated pipe column.
Wherein, described reducer is a planetary reduction gear, and the one end is connected with input shaft coupling and brake and motor in turn, and the other end is connected with output shaft coupling, cylinder bearing in turn and goes up roller bearings and the cylinder of installing.Described motor is a reluctance machine, realizes positive and negative rotation under the control of stroke sensor and switch board.Described pedestal is the skid-mounted type removable frame.Described polished rod upper end is connected with movable pulley, and well head is stretched in the lower end, and is connected with down-hole pump.
The utility model has following advantage compared with prior art:
1, adopt reluctance motor to be used as power, the rotating of can automaticallying switch and running continuously can be gathered the oil well oil test data all-sidedly and accurately, for Reserves Calculation of Oilfield and reservoir geology, oily situation provide accurate research and foundation.
2, the equipment of adopting adopts the skid-mounted type assembling, compact conformation, and mobile removal of home is flexible.
3, the conventional oil well pump that sucker rod drives is adopted in the down-hole, carries out pumping work serially, has avoided leakage of well liquid and the frequent situation of changing swab.
4, well head adopts polished rod, and sealing easily, and is effective, avoided the leakage and the environment pollution of well head.
5, the fracture acidizing integrated pipe column is adopted in the down-hole, has reduced the lower tubular column number of times, alleviates operator's labour intensity, reduces operating cost, and according to measuring and calculating, light is changed one of swab, and each oral examination oil well just can be saved 60,000 yuan, and every mouthful of well of acid fracturing tubing string is saved 110,000 yuan.
