Abstract
The utility model relates to a kind of slim-hole telescoping ram, belong to logging technique field, comprise telescoping ram matrix, described telescoping ram matrix two ends are respectively arranged with upper end modular connection and lower end modular connection, in order to realize standard docking with logger, described telescoping ram matrix has inner concave, telescoping ram matrix two ends in described inner concave are respectively arranged with a sliding rail, the two ends of spring leaf are separately positioned in described sliding rail, and can in sliding rail, slide, thereby make described telescoping ram adapt to the well of different sizes.Slim-hole telescoping ram of the present utility model can be realized multiplexing in same logger string, has effectively solved the situation that non-slim-hole equipment is met card in slim-hole, has guaranteed logging quality, has improved instrument well logging scope.
Description
Technical field
The utility model relates to a kind of slim-hole telescoping ram, belongs to logging technique field.
Background technology
As everyone knows, in prior art, in slim-hole during well logging (such as 6in, even less well), because the external diameter of instrument itself has approached borehole size very much, if additional telescoping ram, the outside dimension of instrument itself will increase, be easy to cause instrument to meet card, thereby cause logging well unsuccessfully, its well logging scope is limited to.Therefore, research and develop and a kind ofly can either solve the normal work of instrument (non-slim-hole equipment) in slim-hole during well logging, can in same logger string, realize again multiplexingly, in order to the slim-hole telescoping ram that guarantees logging quality and improve instrument well logging scope, become technical problem urgently to be resolved hurrily at present.
Utility model content
Based on the problems referred to above, the utility model proposes a kind of slim-hole telescoping ram, it not only can solve instrument (non-slim-hole equipment) and normally work in slim-hole during well logging, and can also in same logger string, realize multiplexing, effectively solve non-slim-hole equipment and in slim-hole, met the situation of card, guarantee logging quality, improved instrument well logging scope.
The technical solution of the utility model is as follows:
A kind of slim-hole telescoping ram, comprise telescoping ram matrix, described telescoping ram matrix two ends are respectively arranged with upper end modular connection and lower end modular connection, in order to realize standard docking with logger, described telescoping ram matrix has inner concave, and the telescoping ram matrix two ends in described inner concave are respectively arranged with a sliding rail, and the two ends of spring leaf are separately positioned in described sliding rail, and can in sliding rail, slide, thereby make described telescoping ram adapt to the well of different sizes.
Further, between the modular connection of described upper end and described telescoping ram matrix, be connected with Rapid-turning nut.
Further, inner concave is one or more.
When described inner concave is one, described telescoping ram matrix is one side indent, is only provided with a single spring leaf, for making described telescoping ram eccentric setting in it.
Or a plurality of described inner concaves are four.Four described inner concaves are symmetrical arranged, and telescoping ram matrix cross sections is square, and are provided with a spring leaf in each inner concave, and four spring leafs make auxiliary placed in the middle setting of described telescoping ram.
Beneficial effect:
Slim-hole telescoping ram of the present utility model is as an instrument pipe nipple, and two sections adopt typical construction, and middle through track connects, and can achieve a butt joint with other loggers, does not increase instrument string diameter.
This kind of slim-hole telescoping ram can meet the operation under slim-hole condition, and can realize in same instrument string multiplexingly, improved job area, guaranteed instrument backup effect, in actual slim-hole application, there is very strong practicality and generalization, dismounting is simple and safe and reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation with an inner concave of the present utility model;
Fig. 2 is the structural representation with four inner concaves of the present utility model;
In figure, 1-telescoping ram matrix; The modular connection of 2-upper end; The modular connection of 3-lower end; 4-Rapid-turning nut; 5-inner concave; 6-sliding rail; 7-spring leaf.
The specific embodiment
Below in conjunction with accompanying drawing, 1-2 is described further the utility model.
Embodiment 1
As shown in Figure 1, a kind of slim-hole telescoping ram of the present utility model, comprise telescoping ram matrix 1, described telescoping ram matrix 1 two ends are respectively arranged with upper end modular connection 2 and lower end modular connection 3, in order to realize standard docking with logger, telescoping ram matrix 1 has inner concave 5, telescoping ram matrix 1 two ends in described inner concave 5 are respectively arranged with a sliding rail 6, the two ends of spring leaf 7 are separately positioned in sliding rail 6, and can be in the interior slip of sliding rail 6, thereby make described telescoping ram adapt to the wells of different sizes.Between upper end modular connection 2 and telescoping ram matrix 1, be connected with Rapid-turning nut 4.Wherein, inner concave 5 is one, and telescoping ram matrix 1 is one side indent, is only provided with a single spring leaf 7, for making described telescoping ram eccentric setting in it.
Embodiment 2
As shown in Figure 2, another kind of slim-hole telescoping ram of the present utility model, its inner concave 5 is four.Four described inner concaves 5 are symmetrical arranged, and telescoping ram matrix 1 cross section is square, and interior 7, four spring leafs 7 of a spring leaf that all can be provided with of each inner concave 5 make auxiliary placed in the middle setting of described telescoping ram.Other structure and annexation, with embodiment 1, no longer repeat (note: do not mark spring leaf 7, Rapid-turning nut 4 and inner concave 5 in figure) herein.
The size of different wells can be used the height of spring leaf 7, and the degree of depth of telescoping ram matrix 1 upper groove and the spacing between sliding rail 6 are adjusted
Be more than two specific embodiments of the present utility model, enforcement of the present utility model is not limited to this.
