Abstract
The utility model discloses an annulus logger confluent-liquid umbrella with protection structure which mainly comprises a double-layer umbrella frame which is provided on an integrated center tube of confluent-liquid umbrella, an umbrella cloth of confluent-liquid umbrella and an inner layer umbrella rib and an outer protective umbrella rib which are designed to be assembled in the order of inside and out while the lashing wire is linked at the bottom to form a structure with an inner rib and an outer rib and the ribs are folded together to be inserted in the upper rib slot and the lower rib slot. The utility model has a rational structure, a reliable performance, a high safety factor in the confluent-liquid umbrella and an obvious effect, and can greatly improve the accuracy and the success rate of the flow measurement of the downhole logger.
Description
Affiliated technical field
The utility model relates in a kind of oil exploitation test process; formation testing use annulus logging instrument current collecting umbrella; especially a kind ofly can in the downhole testing process, have vi have high safety; the novel current collecting umbrella that protects the umbrella structure that protection domain is big; and can improve the flow rate test accuracy rate and the success rate of downhole logging instrument, be applicable to the formation testing of oil gas well.
Background technology
At present; in the oil gas well mining test; the umbrella sheet that protects of the annular tester current collecting umbrella that uses is made as scale copper; size is less, can only partly protect umbrella cloth, only protects current collecting umbrella umbrella footpath the best part; and because the not fixed connection method of employing and current collecting umbrella exumbrella muscle suit; cause in the process of removing, to tangle obstruction and make and protect the umbrella sheet and move and tear current collecting umbrella, cause test crash then, greatly reduce test success rate and accuracy rate at instrument.
Summary of the invention
In order to overcome the technical deficiency that the umbrella sheet exists of protecting of the existing annular tester current collecting umbrella that uses; the utility model provides a kind of annulus logging instrument current collecting umbrella with the protection structure; can in test process, reliably strut repeatedly and close and close, improve the flow rate test accuracy rate and the success rate of downhole logging instrument.
The technical scheme that its technical problem that solves the utility model adopts is: adopt double-layer umbrella umbrella basket structure on the current collecting umbrella central tube of processing one; order design and installation current collecting umbrella umbrella cloth, internal layer umbrella muscle, outer layer protection umbrella muscle from the inside to surface; the umbrella lacing wire connects it down; to constitute inside and outside two layers of umbrella muscle, the umbrella muscle is folded mutually to be constituted with being inserted in the interior connection of umbrella rib base groove up and down.What protect current collecting umbrella is outer layer protection umbrella muscle, and the very thin broad of outer layer protection umbrella muscle can cover whole umbrella cloths under rounding state, effectively solve instrument current collecting umbrella umbrella cloth when annular space removes and easily gall problem, plays the protection cotton umbrella.Internal layer umbrella muscle is thicker, and good springiness works to strut the afflux umbrella cloth and makes it moulding, sealing afflux.During use, the current collecting umbrella that the utility model is constituted is connected in downhole logging instrument, driving the current collecting umbrella folding by the conduction micromachine makes it with in the test job, rational in infrastructure, dependable performance, easy to use, the current collecting umbrella vi have high safety, effect obviously can improve the flow rate test accuracy rate and the success rate of downhole logging instrument greatly.
The beneficial effects of the utility model are that current collecting umbrella struts back outer layer protection umbrella muscle and is close to the afflux umbrella cloth, parachute-opening shape stable molding.After umbrella draws in, make its external diameter, cross annular space at instrument and remove and effectively protected umbrella cloth in the process, make it not fragile less than the instrument external diameter.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a softened state structural representation of the present utility model.
Fig. 2 partly cuts open schematic diagram for concrete structure of the present utility model.
Among the figure: 1. outer layer protection umbrella muscle, 2. current collecting umbrella umbrella cloth, 3. umbrella lacing wire, 4. internal layer umbrella muscle, 5. central tube.
The specific embodiment
Referring to Fig. 1, Fig. 2; go up employing double-layer umbrella umbrella basket structure at the current collecting umbrella central tube (5) of processing one; order design and installation current collecting umbrella umbrella cloth (2), internal layer umbrella muscle (4), outer layer protection umbrella muscle (1) from the inside to surface; umbrella lacing wire (3) connects it down; to constitute inside and outside two layers of umbrella muscle, the umbrella muscle is folded mutually to be constituted with being inserted in the interior connection of umbrella rib base groove up and down.。What protect current collecting umbrella is outer layer protection umbrella muscle (1), and the very thin broad of outer layer protection umbrella muscle (1) can cover whole umbrella cloths under rounding state, effectively solve instrument current collecting umbrella umbrella cloth when annular space removes and easily gall problem, plays the protection cotton umbrella.Internal layer umbrella muscle (4) is thicker, and good springiness works to strut the afflux umbrella cloth and makes it moulding, sealing afflux.During use, the current collecting umbrella that the utility model is constituted is connected in downhole logging instrument, driving the current collecting umbrella folding by the conduction micromachine makes it with in the test job, rational in infrastructure, dependable performance, easy to use, the current collecting umbrella vi have high safety, effect obviously can improve the flow rate test accuracy rate and the success rate of downhole logging instrument greatly.
Claims (1)
1. annulus logging instrument current collecting umbrella that connects the band protection structure that umbrella muscle, umbrella cloth form by the current collecting umbrella central tube; it is characterized in that: adopt double-layer umbrella umbrella basket structure on the current collecting umbrella central tube of processing one; order design and installation current collecting umbrella umbrella cloth, internal layer umbrella muscle, outer layer protection umbrella muscle from the inside to surface; the umbrella lacing wire connects it down; to constitute inside and outside two layers of umbrella muscle, the umbrella muscle is folded mutually to be constituted with being inserted in the interior connection of umbrella rib base groove up and down.
