Description
Technical field
The utility model relates to the petroleum drilling technology field, and particularly a kind of drilling well ground experiment device is a kind of oil drilling hard closing analogue experiment installation.
Background technology
At present, in the petroleum engineering well drilling process, when overflow or blowout occur, can produce the sudden change of pressure jump and flow during owing to closing well.And these two kinds of sudden changes all can produce the very large water hammer of harm.Because the water attack meeting makes superpressure in preventer inside and the well at the very large pressure of moment generation, and easy link (such as the casing shoe place) generation pressure leakage stratum accident the weakest in well, thereby normal wellbore construction affected.Therefore, water attack problem obtains paying attention to more and more widely.
The scene shows: if take " soft closing " mode, although the surge pressure during closing well is less to formation damage, but owing to can cause the further intrusion well of formation fluid, cause the generation of parasitic pressure drop, thereby increase stratum, casing shoe place by the danger of pressure break, be unfavorable for next step kill job; If take " hard closing ", surge pressure will impact preventer when then worrying closing well.Want reasonable selection closing well mode and just need to carry out ground experiment, the water attack problem when making closing well clear.Because a bite oil well is very high at cost, and hard closing might damage oil well, therefore, should not measure the surge pressure of closing well process in drilling process.
Method and the device of the Water Hammer that well head and casing shoe place produce when now, energy Accurate Determining hard closing being arranged not yet.
The utility model content
The purpose of this utility model is: a kind of oil drilling hard closing analogue experiment installation is provided, can carries out carrying out the test of hard closing surge pressure on ground when overflow and blowout.Use the simulation hard closing under the principle of similitude to avoid risk, save cost, and be used for instructing drilling well production.
The technical solution adopted in the utility model is: oil drilling hard closing analogue experiment installation, comprise water tank, centrifugal pump, flap valve, the first pressure sensor, first flow meter, the second pressure sensor, the first electromagnetic valve, the 3rd pressure sensor, the second electromagnetic valve and the second flow meter, it is characterized in that: the entrance that connects centrifugal pump at the delivery port of water tank by pipeline; Centrifugal delivery side of pump connects flap valve, the first pressure sensor and first flow meter successively by pvc pipe; The port of export of first flow meter connects the second pressure sensor, the first electromagnetic valve, the 3rd pressure sensor and the second electromagnetic valve successively by pvc pipe; The port of export of the second electromagnetic valve connects the arrival end of the second flow meter by pvc pipe, and the port of export of the second flow meter connects pvc pipe.
Described the first pressure sensor, first flow meter, the second pressure sensor, the 3rd pressure sensor and the flow meter of being connected connect the computer data acquiring card by holding wire.
The operating principle of summary oil drilling hard closing analogue experiment installation.Consult Fig. 1.Centrifugal pump 2 obtains fluid and it is pumped in the pvc pipe from water tank 1, flap valve 3, electromagnetic valve 7 and electromagnetic valve 9 are all opened at this moment, show value electromagnetic valve for adjusting 9 according to flow meter 10, make the flow in the pipeline meet the flow rate calculation value that draws according to the principle of similitude, the measured value of record pressure sensor 8.Then the simulation closed-in time that calculates according to the principle of similitude, shut electromagnetic valve 7 with the measured value of data collecting card record pressure sensor 6, pressure sensor 4 and flow meter 5, and carries out the water attack analog computation of hard closing according to the principle of similitude.When changing, water attack time and flow repeat above-mentioned steps.Use centrifugal pump, pressure sensor, flow meter and choke valve to realize the adjusting of flow, mensuration and the simulation of surge pressure.Use the common PVC pipe die to intend well casing, and install back pressure valve, pressure sensor, choke valve and flow meter at pipeline.But choke valve flexible modulation flow, flow and pressure in pressure sensor and the flow transmitter energy Accurate Determining pipeline, and can use capture card to carry out data acquisition.
The beneficial effects of the utility model: the utility model oil drilling hard closing analogue experiment installation, can realize different flow, the drilling well water attack pressure simulation of different closed-in times mensuration, can use routine, normal pressure equipment to realize the hard closing simulation is carried out in overflow and blowout operating mode, and measure (actual condition also be difficult to measure) without actual condition, have cheap, be easy to measure, reduce the advantages such as engineering risk.
