Abstract
The utility model relates to the technical field of layered and segmented exploitation of an oil and gas well, in particular to a control sliding sleeve switch. An upper joint (1) and a transition sleeve (2), and a positioning outer sleeve (4) and a lower joint (5) of the control sliding sleeve switch are in screwed connection respectively; a support block (3) is embedded between the transition sleeve (2) and the positioning outer sleeve (4); a piston (6) and a positioning part (7) are pressed in a range limited by the upper joint (1) and the lower joint (5); and a compression spring (8) is arranged in an annular space formed by the positioning outer sleeve (4), the lower joint (5) and the positioning part (7). The switch can switch on and off a control sliding sleeve for the segmented exploitation of the oil and gas well, and can switch on and off a plurality of sliding sleeves at one time.
Description
Technical field:
The utility model relates to the technical field of the separate zone production of a kind of oil gas well, segmentation exploitation, particularly a kind of downhole tool of controlling sliding sleeve switch.
Background technology:
In present oil gas well, the multilayer that the individual well exploitation is different or the situation of the long horizontal segment of individual layer are very general, because the production life-span of the complexity of geologic(al) factor, difference, each layer or each section of flow resistance is different different with product aquatic products sand situation, have only the branch of realizing different intervals to adopt control and just can effectively close water exit interval, realize the segmentation well stimulation, thereby the branch of realizing different intervals is adopted control and had significant technical advantage for the production capacity of the whole intervals of performance individual well.
The utility model content:
The technical problems to be solved in the utility model provides a kind of oil gas well mining segmentation control sliding sleeve switch, and this control sliding sleeve switch has realized that can control sliding sleeve to oil gas well segmentation exploitation play on-off action, and can a plurality of sliding sleeves of single switch.
Technical solution adopted in the utility model is: a kind of oil gas well mining segmentation control sliding sleeve switch is become with compression spring set by top connection, spacer shell, back-up block, location overcoat, lower contact, piston, positioning element; Top connection and spacer shell, location overcoat and lower contact are screwed connection, back-up block is embedded in the middle of spacer shell and the location overcoat, piston and positioning element bear against in top connection and lower contact institute restricted portion, and the compression spring is contained in the annular space that location overcoat, lower contact and positioning element form.
The beneficial effects of the utility model are: the utility model since adopted with back-up block be embedded into spacer shell and the location overcoat in the middle of, piston and positioning element bear against the structure in top connection and lower contact institute restricted portion, thereby have and to play on-off action to oil gas well segmentation exploitation control sliding sleeve, and function that can a plurality of sliding sleeves of single switch.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
As shown in drawings, a kind of oil gas well mining segmentation control sliding sleeve switch is made up of top connection 1, spacer shell 2, back-up block 3, location overcoat 4, lower contact 5, piston 6, positioning element 7 and compression spring 8; Top connection 1 is screwed connection with spacer shell 2, location overcoat 4 with lower contact 5, back-up block 3 is embedded in the middle of spacer shell 2 and the location overcoat 4, piston 6 and positioning element 7 bear against in top connection 1 and 5 restricted portions of lower contact, and compression spring 8 is contained in the annular space that location overcoat 4, lower contact 5 and positioning element 7 formed.
When wanting the operation that sliding sleeve is opened or closed, the working string relevant position connects this utility model, and is lowered to the shaft bottom.Suppress by ground, pressure reduction moved downward about the piston 6 of this utility model was subjected to tubing string, compression spring 8 continues to be compressed, back-up block 3 is owing to the backup effect on inclined-plane is radially extruded, match with the stepped recesses of sliding sleeve instrument, open or close the sliding sleeve operation, positioning element 7 oppositely pushed back to original position with back-up block 3 in an identical manner after operation was finished under the effect of compression spring 8, tripped out working string.
Claims (1)
1. an oil gas well mining segmentation control sliding sleeve switch is made up of top connection (1), spacer shell (2), back-up block (3), location overcoat (4), lower contact (5), piston (6), positioning element (7) and compression spring (8); It is characterized in that: top connection (1) is screwed connection with spacer shell (2), location overcoat (4) with lower contact (5), back-up block (3) is embedded in the middle of spacer shell (2) and the location overcoat (4), piston (6) and positioning element (7) bear against in top connection (1) and lower contact (5) institute restricted portion, and compression spring (8) is contained in the annular space that location overcoat (4), lower contact (5) and positioning element (7) formed.
