Abstract
The utility model provides an underground anti-winding eccentric locator for a testing cable. An upper joint and a lower joint connected with an oil tube are respectively arranged on and under the locator, wherein an anti-winding location tube is arranged on the middle part, an anti-winding blade is connected on the anti-winding location tube, the lower joint is connected with fixed pins, the lower end of the anti-winding location tube is provided with a plurality of grooves matched with the fixed pins, and the upper end of the anti-winding location tube is further connected with a pressing cap connected with a baffle ring. The baffle ring is connected on the pressing cap, and the anti-winding blade is spirally connected on the outer surface of the anti-winding location tube. The pressing cap acts together with the fixed pins so as to prevent the anti-winding location tube from moving and play a location role; and the baffle ring can ensure that the pressing cap drops in the operation process.
Description
Technical field
The utility model relates to heavy crude heat extraction producing well downhole testing technical field, particularly is applicable to the anti-tangle eccentric locater of oil jacket annulus logging operation process.
Background technology
Along with the oil field enters tail period, production logging more and more demonstrates its importance.Since the impact of heavy crude reservoir time end water and the impact of viscous crude crude oil property, the high moisture phenomenon of heavy crude well ubiquity.Therefore, determine the production profile of oil well, especially production profile becomes evaluation production efficiency, understands payzone dynamic, carries out the payzone transformation, adjusts injection-production program, alleviates the Main Basis of interlayer contradiction.Generally in the sucker rod pumping well adopt annulus logging, because the annular space method does not need moving flow string, can survey while taking out, little and generally come into one's own to the interference of producing well reset condition.Yet during annulus logging, because the annular space space is little in the test process, test cable is difficult to remove, and easily twines, is hampered, and can't guarantee normally carrying out of heavy crude heat extraction down-hole producing profile testing work.
In view of this, for the problems referred to above, propose a kind of reasonable in design and effectively improve the anti-tangle eccentric locater in test cable down-hole of above-mentioned disappearance.
Summary of the invention
The purpose of this utility model provides the anti-tangle eccentric locater in test cable down-hole, little for annular space space in the heavy crude heat extraction producing well production profile direct reading test process, test cable is lowered in the process and easily is hampered, twines, the problem that is difficult to remove, develop the anti-tangle locator of special construction, guaranteed heavy crude heat extraction producing well producing profile testing everything goes well with your work to carry out.
The purpose of this utility model can be achieved by the following technical measures:
This anti-tangle eccentric locater in test cable down-hole is upper and lower respectively top connection, the lower contact that is connected with oil pipe, above having, the middle part is connected with the anti-tangle positioning pipe of anti-tangle blade, lower contact is connected and fixed pin, the lower end of anti-tangle positioning pipe is provided with a plurality of grooves that match with steady pin, and anti-tangle positioning pipe upper end is connected with the pressure cap that connects baffle ring.
The purpose of this utility model also can be achieved by the following technical measures:
Be connected with baffle ring on the described pressure cap; Described anti-tangle blade screw shape is connected in anti-tangle positioning pipe external surface.Described upper and lower joint is connected with tubing nipple respectively, and whole eccentric locater is fixed on the tubing nipple; Described steady pin is on tubing nipple; Described anti-tangle positioning pipe sleeve is in the tubing nipple outside, and there are a plurality of grooves its lower end, inserts after suitable angle is aimed at steady pin with groove by rotating to; Described anti-tangle blade is welded in above the anti-tangle positioning pipe; Connect baffle ring on the described pressure cap, the anti-tangle positioning pipe of lower connection upper end; Described pressure cap and steady pin acting in conjunction avoid anti-tangle positioning pipe to rotate, and play positioning action; Described baffle ring guarantees that pressure cap comes off in operation process.
The utility model can make the oil pipe one side sleeve pipe of trying one's best, and guarantees the maximization of opposite side annular space space, has reserved sufficient space for test cable, has prevented that test cable from removing process and piling up, twine, thereby realizes effective enforcement of producing profile testing technique.This utility model is simple and practical, and operation is convenient, and safe and reliable, life cycle is long, and test cable removes easily, is hampered little, and is antiwind, cooperates preferably to realize heavy crude heat extraction producing well producing profile testing; High temperature resistant 350 ℃, high pressure 25MPa.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structure top view of the utility model embodiment;
Fig. 3 is the stereogram of the utility model embodiment;
Fig. 4 is that the utility model embodiment places the state diagram on " 7 cun " sleeve pipe.
Among the figure, 1-top connection, 2-baffle ring, 3-pressure cap, the anti-tangle positioning pipe of 4-, the anti-tangle blade of 5-, 6-steady pin, 7-lower contact.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in drawings, top connection 1, lower contact 7 are connected with tubing nipple respectively, and eccentric locater is fixed on the tubing nipple; Steady pin 6 tubing nipple above; Anti-tangle positioning pipe 4 is enclosed within the tubing nipple outside, there are a plurality of grooves its lower end, by rotation, after forwarding suitable angle to, insert after notch aimed at steady pin 6, guarantee that anti-tangle positioning pipe 4 no longer rotates, anti-tangle blade 5 is at anti-tangle positioning pipe 4 external surface spirally-wounds and weld together, and the anti-tangle eccentric locater in made test cable down-hole of anti-tangle blade 5 removes smoothly; Connect baffle ring on the pressure cap 3, the anti-tangle positioning pipe of lower connection 4 upper ends, itself and steady pin 6 actings in conjunction avoid anti-tangle positioning pipe to rotate, and play positioning action; Baffle ring 2 guarantees that pressure cap 3 comes off in operation process.
In the downhole testing operation, according to actual conditions, can adopt a plurality of anti-tangle eccentric locaters at the down-hole different parts, by rotation, so that anti-tangle opening direction is consistent, to accomplish the end in view.
