Abstract
The utility model relates to a kind of hydraulic shear pin completion tubular column running tool.Mainly solve the hanging hydraulic releasing of existing ball existed in prior art and hang the yielding problem causing throwing off of steel ball.It is characterized in that: described top connection (1) cuts off (4) with lower contact (6) by some suspensions and is connected, top connection (1) and lower contact (6) joint end face place are equipped with corresponding stop pin (3), stop pin (3) is connected with lower contact (6) top, and first, top connection (1) lower end reducing place radial direction has pressure transmission hole (5).This hydraulic shear pin completion tubular column running tool, according to the completion tubular column of different length, weight, can cut off connection and regulates accordingly, efficiently solves completion tubular column and sends into the situation of losing not open after in well.
Description
Technical field
The utility model relates to a kind of tubing string running tool in petroleum drilling engineering technical field, particularly a kind of hydraulic shear pin completion tubular column running tool.
Background technology
At present, nitrogen under balance pressure drilling technique is the drilling technology that conventional drilling combines with nitrogen under balance pressure drilling, this technology formation no pollution and without chip hold down, can improve recovery ratio by formation protection to greatest extent.Utilize conventional drilling technique pierce oil top but do not open oil reservoir during operation, drill oil reservoir by nitrogen under balance pressure drilling technique and be drilled into the oil end below 20m.The mode completion that nitrogen under balance pressure drilling well section oil pipe combines with screen casing, tubing string releasing tool is sent into, and requires that latus rectum of giving up is greater than completion tubular column latus rectum and has and can drag for function.
The hanging hydraulic releasing tool of existing ball, the upper and lower joint of releasing tool is connected by axially uniform steel ball, has corresponding engaging tooth in conjunction with end face, can transmit the pressure of the drill again can transmitting torque, when sealed steel ball drops on piston, runner seals by sealed steel ball, and pressure increase cuts off pin, descent of piston is to baffle plate, now upper lifting pipe post, connects steel ball and is pushed in upper back-off sub by the inclined-plane in lower back-off sub, Joint failure, pressure declines rapidly, and implementation tool is thrown off.This shortcoming existed of giving up is: 1. do not have rotation-preventing mechanism between upper and lower joint, cannot transmitting torque when being hampered; 2. serious by hole deviation restriction, suspension steel ball and lower contact surface groove are point cantact, easily form groove at inclined-plane place, hinder the later stage to throw off action.This structure is only applicable to straight well or low-angle directional well, is not suitable for horizontal well or wide-angle directional well.
Summary of the invention
Technical problem to be solved in the utility model overcomes the hanging hydraulic releasing of existing ball existed in background technology to hang the yielding problem causing throwing off of steel ball, and a kind of hydraulic shear pin completion tubular column running tool is provided, this hydraulic shear pin completion tubular column running tool, can according to the completion tubular column of different length, weight, cut off connection and regulate accordingly, instrument disengagement success rate is high.
The invention for solving the technical problem reaches by following technical scheme: this hydraulic shear pin completion tubular column running tool, comprise top connection and lower contact, described top connection and lower contact are cut off by some suspensions and are connected, top connection and lower contact joint end face place are equipped with corresponding stop pin, stop pin is connected with lower contact top, and first, top connection lower end reducing place radial direction has pressure transmission hole
The utility model can have following beneficial effect compared with above-mentioned background technology: this hydraulic shear pin completion tubular column running tool is owing to adopting said structure, instrument disengagement success rate is high, releasing tool uses normal, enter under completion tubular column is smooth, meet onsite application condition, effectively avoid giving up and throw off a difficult problem for the tool failures unsuccessfully caused.This instrument and nitrogen under balance pressure drilling support the use, and formation protection improves production yield rate.
accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
In figure: 1-top connection, 2-sealed steel ball, 3-stop pin, 4-hang cut off, 5-pressure transmission hole, 6-lower contact.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this hydraulic shear pin completion tubular column running tool comprises top connection 1 and lower contact 6, top connection 1 cuts off 4 with lower contact 6 by suspension and is connected, and described suspension cuts off 4 circumferences and is distributed on lower contact 6 end, and it is more stable that suspension cuts off the uniform disengagement pressure that can make of 4 circumference; Top connection 1 and lower contact 6 joint end face place are equipped with corresponding stop pin 3, and stop pin 3 is connected with lower contact 6 top, can transmit the pressure of the drill, also can transmitting torque; First, top connection 1 lower end reducing place radial direction has pressure transmission hole 5, by fluid pressure, instrument is thrown off, and ensures the success rate that instrument is thrown off.
This hydraulic shear pin completion tubular column running tool, when sealed steel ball 2 drops on the ball seat in top connection 1, sealed by runner, the pressure of generation enters in high pressure chest by pressure transmission hole 5, is acted on by pressure on the sealed section of lower contact 6.It is descending that pressure promotes lower contact 6, and when arrival is hung and cut off the shear pressure of 4, cut off disconnection, now upper lifting pipe post, sealing was lost efficacy with being connected simultaneously, and pressure declines rapidly, realizes throwing off.
Claims (2)
