The device disclosed by the utility model is mainly used for preparing the artificial core with the anti-sand proppant and preparing other artificial cores.
Description
Technical field
The utility model relates to a kind of preparation facilities for oil field artificial rock core, particularly relates to a kind of sand control propping agent artificial rock core preparation facilities.
Background technology
At present, Oil/gas Well sand control is applied more and more widely as the measure of an oilfield stable production and volume increase, particularly most domestic has entered the oil field of exploitation middle and later periods, impact due to geologic agent and engineering factor, oil-water well downhole conditions constantly worsens, in the situation that conventional mechanical sand control cannot satisfy the demands, the advantage of chemical sand control is more and more obvious.For chemical sand control, the compressive strength of propping agent, permeability, acid and alkali resistance intensity, set time, it is particularly important that anti-aging intensity etc. seems.Shop experiment is the basis of sand control propping agent rig-site utilization, and the preparation facilities of a good artificial rock core is extremely important to the research of the every characteristic of artificial rock core.The preparation of artificial rock core at present, mainly by solidifying in propping agent glass tube, after solidifying is smashed glass tube, then is carried out the mensuration of other every characteristics, and this preparation method not only success ratio is low, can not recycle, and has also caused the huge waste of cost.Other some artificial core preparing device complex process, can accurately simulation well bottom pressure, and temperature etc. lack authenticity thereby cause to the experiment of artificial rock core characteristic.
Utility model content
For the above-mentioned defect of prior art, the technical problems to be solved in the utility model is to provide a kind of sand control propping agent artificial rock core preparation facilities, and solving artificial rock core preparation facilities can not recycle, complex process, can better simulation well bottom pressure, the problem of temperature etc.
For solving the problems of the technologies described above, the utility model sand control propping agent artificial rock core preparation facilities is comprised of base 1, cylindrical shell 3, piston 4, turning axle 5 and gland 6, above-mentioned piston 4 is arranged on cylindrical shell 3 inside, and cylindrical shell 3 lower ends are threaded with base 1, and these cylindrical shell 3 tops are threaded with gland 6; Above-mentioned turning axle 5 is arranged on the inside of cylindrical shell 3, and these turning axle 5 lower ends are threaded with piston 4, and these turning axle 5 tops are threaded with gland 6.
As a kind of improvement of the present utility model, above-mentioned base 1 inside arranges pad 2.
As the utility model, further improve, above-mentioned pad 2 is identical with cylindrical shell 3 internal diameters.
As another kind of improvement of the present utility model, above-mentioned turning axle 5 upper ends are provided with rotating hole 7.
Above-mentioned turning axle 5 is connected for trapezoidal coarse thread with gland 6.
Compare with present technical scheme, the utility model sand control propping agent artificial rock core preparation facilities can carry out the preparation of various propping agent artificial rock cores, can repetitive cycling utilization, situation at the bottom of simulation well, simple in structure, easy to operate preferably, the features such as reliability is high, satisfactory for result.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model sand control propping agent artificial rock core preparation facilities.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model sand control propping agent artificial rock core preparation facilities is comprised of base 1, cylindrical shell 3, piston 4, turning axle 5 and gland 6, above-mentioned piston 4 is arranged on cylindrical shell 3 inside, and cylindrical shell 3 lower ends are threaded with base 1, and these cylindrical shell 3 tops are threaded with gland 6; Above-mentioned turning axle 5 is arranged on the inside of cylindrical shell 3, and these turning axle 5 lower ends are threaded with piston 4, and these turning axle 5 tops are threaded with gland 6.Above-mentioned base 1 inside arranges pad 2.Above-mentioned pad 2 is identical with cylindrical shell 3 internal diameters.Above-mentioned turning axle 5 upper ends are provided with rotating hole 7.Above-mentioned turning axle 5 is connected for trapezoidal coarse thread with gland 6.
The process implementations such as its function of the utility model sand control propping agent artificial rock core preparation facilities is mainly coagulated by feeding, waiting, feeding.
Charging: take a certain amount of propping agent with electronic scale, and stir in beaker with the sand-carrying agent of respective amount, after propping agent is packed in the cylindrical shell 3 of this artificial rock core preparation facilities, with lever rotation turning axle 5, propping agent is compressed, after compression, because of turning axle 5 with gland 6 for being threaded, guarantee that propping agent has constant pressure between waiting-on-cement, thereby realize charging process.
Wait solidifying: the water bath with thermostatic control that the artificial rock core preparation facilities that installs propping agent is put into simulation bottom temperature is waited and coagulated, and records curing time.
Feeding: after reaching the corresponding curing time of propping agent, this artificial rock core preparation facilities is taken out from water bath with thermostatic control, unload lower bottom base 1 and pad 2, rotation turning axle 5 ejects cylindrical shell 3 by waiting the artificial rock core having coagulated, artificial rock core has just been prepared, and can carry out the mensuration of other characteristics of artificial rock core, and artificial rock core preparation facilities can continue recycling, without changing spare part, thereby realize the preparation process of whole artificial rock core.
