An underground multi-controller comprises a central pipe, an outer sleeve, a push piston, a control piston, a sub-control joint and a spring, and is characterized in that the central pipe is installed in the outer sleeve, the control piston and the push piston are sequentially installed between the central pipe and the outer sleeve, the sub-control joint is installed at the lower end of the control piston of an outer sleeve, and the spring is installed at the upper end of the control piston. The underground multi-controller has reasonable and simple structure and high reliability, is easy in construction and installation, can control a liquid control sliding sleeve on optional layers, has high accuracy and high efficiency, can control four layers simultaneously, has low cost, and can be widely applied to oil extraction process strings.
Description
One, technical field
The utility model relates to the oil exploitation downhole tool, particularly a kind of down-hole multiplexer (MUX.
Two, background technology
At present, the control of oil exploitation well oil production by layer, general every layer hydraulic control sliding sleeve is controlled by two pipelines.It is many more that this controlling organization exists oil reservoir, and the control pipeline of G.I.H is many more, and the well gut line is many so first, and complex procedures job execution difficulty is big, and second pipeline is many, and material usage is big, shortcoming or deficiencies such as cost height.
Three, summary of the invention
The purpose of this utility model provides a kind of improved down-hole multiplexer (MUX, adopt the multichannel controlling organization, make the axially-movable of its piston convert rotatablely moving of control piston to by track by hydraulic coupling, make piston aim at different hydraulic control pipelines, the hydraulic control sliding sleeve of control different layers position overcomes the problem of avoiding above-mentioned prior art to exist effectively.
Down-hole described in the utility model multiplexer (MUX comprises central tube, overcoat, promotion piston, control piston, branch control joint and spring.Described central tube is installed in the overcoat, control piston is installed between central tube and the overcoat in turn and promotes piston, and overcoat and control piston lower end are equipped with branch control joint, and the control piston upper end is equipped with spring.
Wherein, described outer putting is provided with long liquid flow hole road and short liquid flow hole road.Described promotion piston outer surface of upper is provided with axial slideway.Described control piston external surface middle part is provided with inclined ramp, and an end of rotation pin is in this inclined ramp.Be provided with the annular space runner between described control piston and the central tube, this runner is connected with short liquid flow hole road.Described control piston is provided with two passage pressure transmission holes, and the steel ball and the little spring that constitute ball-and-seat are installed in one of them passage pressure transmission hole, and this passage pressure transmission hole that ball-and-seat is installed is connected with long liquid flow hole road.Be distributed with 6-8 pressure transmission hole on the described branch control joint circumference, these pressure transmission holes can be connected with the passage pressure transmission hole of control piston respectively.
The utility model has following advantage compared with prior art:
1, rational in infrastructure, simple, reliability is high, easy construction and installation;
2, can control the hydraulic control sliding sleeve of any one deck, the accuracy rate height;
3, the control number of plies is many, and the efficient height can be controlled four layers simultaneously, and cost is low.
