Accompanying drawing explanation
Fig. 1 is the structural representation of the voltage-controlled damping hydraulic pushing of the utility model device.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, the voltage-controlled damping hydraulic pushing of the utility model device, by beaer 1, voltage-controlled body 2, spring base 4, Compress Spring 6, off-load joint 7, large Compress Spring 9 and shock reducing structure 10 form, beaer 1 upper end adopts and is threaded with instrument string, in the middle of beaer 1, it is stepped cylindrical hole, in beaer 1 lower end cylindrical hole, put into voltage-controlled body 2, the column type connecting rod that has downward protrusion at voltage-controlled body 2 centers, the column type connecting rod that voltage-controlled body 2 protrudes downwards withstands on spring base 4 upper ends, Compress Spring 6 is arranged on spring base 4 lower ends, after spring base 4 connects with Compress Spring, put into off-load joint 7 cylindrical holes, spring base 4 can be considered piston with Compress Spring 6, voltage-controlled body 2 lower ends contact with spring base 4, beaer 1 adopts and is threaded with off-load joint 7.The power of flow action on voltage-controlled body 2, and then promote spring base 4 and move down in off-load joint 7 cylindrical holes with Compress Spring 6, (enter-B of A goes out) fluid passage formed; O type circle 3 is housed in off-load joint 7 centre bores, and off-load joint 7 lower ends are run through and are connected with shock reducing structure 10 employing spacer pins 8, and off-load joint 7 middle part reduced diameter portions have equally distributed hole, have installed 1 with shaft roller 5 in each hole; Off-load joint 7 lower ends have column type through hole, and for mounting limit pin 8, spacer pin 8 is arranged on off-load joint 7; Shock reducing structure 10 reduced diameter portions are provided with large Compress Spring 9, and centre has slotted hole, and spacer pin 8 is through this slotted hole.When shock reducing structure 2 is stressed in bottom, rely on the elasticity of large Compress Spring 9, shock reducing structure 10 is moved on slowly, play the effect of damping.
The voltage-controlled damping hydraulic pushing of the utility model device can well reduce the resistance between instrument string and the borehole wall, due to the design of spring base 4 with Compress Spring 6, reduces the generation of the situation that builds the pressure; Large Compress Spring 9 reduces the probability that instrument string damages, and improves efficiency of construction.This voltage-controlled damping hydraulic pushing apparatus structure is simple, assembling easy maintenance, is convenient to assembling, reusable, and safety, reliability are high.
The voltage-controlled damping hydraulic pushing of the utility model device, for horizontal well test job, during work, relies on ground water filling, and instrument place tubing string internal pressure is increased, and when pressure is enough large, will promotes instrument and move in horizontal segment, and instrument is delivered to the object degree of depth.Voltage-controlled damping hydraulic pushing device inner flow passage forms current eddy current, plays the effect that increases hydraulic pushing power.When voltage-controlled damping hydraulic pushing device occurs extremely in pit shaft, during stuck tubing string, voltage-controlled body 2, spring base 4 and Compress Spring 6 actings in conjunction, when building the pressure to a certain extent, spring base 4 moves down, make the inner fluid course (A enters B and goes out) that forms of voltage-controlled damping hydraulic pushing device, avoided the risk building the pressure.In addition, while occurring suddenly gushing on fluid in well, on spring base 4, move, fluid can form fluid course (B enters A and goes out) voltage-controlled damping hydraulic pushing tool is inner equally, thereby has improved the safety factor in test process.
Site work process is as follows: install after the voltage-controlled damping hydraulic pushing of the utility model device, the aids such as voltage-controlled damping hydraulic pushing device, logger, universal joint are connected, consist of logger string; Voltage-controlled damping hydraulic pushing device is connected to logger Chuan lower end.By cable nose, with cable, remove together with logger string.Before well logging, first use drift size gauge tool drifting, determine the position that is hampered.Install after well head and surface line, after checking that tension system, depth system are errorless, the instrument string combining is put into pit shaft, rely on logger string self gravitation, with per hour be not more than 3000 meters test the speed by under logger string to the position that is naturally hampered, after being hampered, slowly upwards carry instrument string, note observing the situation of change of tensiometer.After if tension force shows normally, according to ground experiment data, start well head pump, water is injected in pit shaft and is applied on pressure-controlled hydraulic pushing device, promotion instrument string is descending, after pump pressure and stability of flow, observes the situation of change of tensiometer, slowly descend payout, in decentralization process, note observing at any time the situation of change of tensiometer, the degree of depth, well head flow, pump pressure; After being hampered, close well head pump, carry logger string on slowly.
The voltage-controlled damping hydraulic pushing of the utility model device can well reduce the resistance between instrument string and the borehole wall, due to the design of spring base 4 with Compress Spring 6, reduces the generation of the situation that builds the pressure, and reduces the probability that instrument string damages, and improves efficiency of construction.The voltage-controlled damping hydraulic pushing of the utility model apparatus structure is simple, assembling easy maintenance, is convenient to assembling, reusable, and safety, reliability are high.
