Operating principle of the present utility model is:
The switch and the sampling of ball valve in the downhole tool are operated and controlled to the utility model by means of the upper and lower motion of drilling rod or oil pipe, produces time-delay in the ball valve switching process.When transferring drilling rod or oil pipe, ball valve 39 is in closed condition, the connection pipe nipple 14 of inversion mechanism, axle 15 driven together to be moved downward, but can not rotate, because axle 15 lower ends are milled with spline and key cover 20 are inserted in the spline, so when connection pipe nipple 14, when axle 15 moves downward, transposition back-up ring 17 rotates along the transposition grooves; When connection pipe nipple 14, when axle 15 moves downward with drilling rod or oil pipe, transposition ring washer 17 is just changed to another position from a position.When drilling rod or oil pipe pressurizeed downwards, the upper spindle 22 of time-delay mechanism moved down, and promoted time-delay valve 26 and moved down simultaneously, compression hydraulic oil.Hydraulic oil slowly permeates to the top of upper spindle 22 by the gap between time-delay valve 26 and the time-delay urceolus 25, produces time-delay.After time-delay valve 26 integral body moved time-delay urceolus 25 internal diameters change general goal, because the gap between time-delay valve 26 and the time-delay urceolus 25 becomes big, move on to axle top on hydraulic oil is quick, the resistance force diminishes of time-delay valve 26, drilling rod or the oil pipe 36.4mm that drops suddenly, this action is opened for ball valve and is shown, can obviously observe on ground.When driving upper and lower axle 22,30 moving down when drilling rod or oil pipe move down, connector 33 also moves down simultaneously.When time-delay mechanism finishes time-delay, when drilling rod or oil pipe dropped suddenly, connector 33 spendings drove operative pins 35 and move down, and drove ball valve 39 and rotate.When ball valve 39 turns over 90 °, be in full open position.After ball valve 39 is opened, hydraulic pressure axle 8 will cut off 10 and cut off under the strata pressure effect, and hydraulic pressure axle 8 moves up, and discharge hydraulic oil, and hydraulic oil flows into air chamber, and formation fluid enters sampling cavity, begin sampling.After the end, sampling axle 4 moves up under the formation fluid pressure effect, closes sampler, and fixing by lock dog 2.
If close ball valve 39, on carry drilling rod or oil pipe, connector 33 also with on move, after after a while, connector 33 begins to drive operative pin 35 and moves up, and drives 90 ° of ball valve 39 revolutions, ball valve is in closed condition.Can raise and decentralize drilling rod or oil pipe repeatedly,, obtain repeatedly to flow and the closing well phase, can not cause cloudy flow phenomenon more than 39 open and close of ball valve.
The utility model adopts big latus rectum, big flow, all-pass footpath, the design of sampling automatically, communicates between the axle of each mechanism, and interior hole path is according to using needs to can be φ 44～58mm; And the urceolus external diameter of each mechanism can be φ 98～130mm.Each junction of tester upper and lower end all adopts CAS to be threaded, can be high pressure resistant.
The utility model is mainly used in oil well drillstem test and well completing test, and can be used for other lucky operation down, is applicable to multiple media such as down-hole oil reservoir, water layer, natural gas.When formation testing, provide major path, can descend electronic pressure gauge or other tester, the data of estimating the stratum can be provided more accurately.
