Preferably, be provided with pressure interface (31) on the cover (3).
Preferably, pressure interface (31) the connecting fluid pressure pipe of cover (3) remittance (6).
Preferably, be provided with pressure control valve (7) on the hydraulic pressure manifold (6).
Preferably, be provided with tensimeter (61) on the hydraulic pressure manifold (6).
A plurality of holes that different pore size preferably, is arranged on chassis (5).
Preferably, chassis (5) lower surface is provided with rotatable scraper (30).
Embodiment of the present utility model not only exactly the appraisal drilling liquid system suppress the size of coated performance, can also react the hardness level of landwaste piece under the drilling well Dynamic Construction condition of simulation simultaneously.Embodiment of the present utility model has the characteristics of strong operability, is highly suitable for wellbore construction.
Description of drawings
Fig. 1 is the organigram that the drilling fluid system of the utility model embodiment suppresses coated performance evaluation equipment.
Embodiment
The below will be described in further detail the utility model, so that those skilled in the art can put into practice the utility model.Should be appreciated that and to adopt other embodiments, and can make suitable change and do not depart from spirit or scope of the present utility model.For fear of for making those skilled in the art can put into practice unnecessary details the utility model, instructions may omit some known to those skilled in the art information.Therefore, below describe in detail and should not understand with restrictive meaning, and scope of the present utility model is only defined by claims.
See also Fig. 1, it is that drilling fluid system described in the utility model suppresses coated performance evaluation equipment.As shown in Figure 1, drilling fluid system of the present utility model suppresses coated performance evaluation equipment and mainly comprises support 1, test tank 2, cover 3, base ring 4, chassis 5, take-up reel 8, snap ring 9 and meausring apparatus 10 etc.
Test tank 2 is fixed on by snap ring 9 on the support 1 of vertical placement, and two snap rings 9 are embraced test tank 2 from the outside surface annular one on the other.
The top of test tank 2 has been threaded connection cover 3.Chassis 5 is positioned at the bottom of test tank 2, is provided with a plurality of holes of different pore size on it.The bottom periphery of test tank 2 has been threaded connection base ring 4.
Include in the test tank 2 space in the tank is isolated into up and down two-part batching plug 21, this batching plug 21 can under the pressure of gas or liquid, move up and down in test tank 2.The space of batching plug 21 tops is pressure space 22 in the test tank 2, and the space of batching plug 21 belows is drilling cuttings lab space 23.
Be provided with pressure interface 31 on the cover 3, can connect the external pressure supply arrangement such as hydraulically operated equipment (HOE) etc.Among the embodiment of the present utility model, the pressure interface 31 on the cover 3 connects hydraulically operated equipment (HOE) by hydraulic pressure manifold 6.Be provided with pressure control valve 7 on the hydraulic pressure manifold 6.On hydraulic pressure manifold 6, tensimeter 61 can also be set, so that the pressure in the Real Time Observation pressure space 22.
Test tank 2 is suspended in take-up reel 8 tops, and take-up reel 8 is placed on the meausring apparatus 10, the quality of the object that Real-time Collection take-up reel 8 receives.
Embodiment of the present utility model can also arrange scraper 30 by 5 lower surfaces on the chassis, and by revolving scraper 30, the soil paste (part landwaste piece aquation forms soil paste in water) that pressurized in the drilling cuttings lab space 23 can be seen through chassis 5 scrapes in the take-up reel 8.
Because the hardness of the landwaste piece that soaked in drilling fluid system is relevant with the coated performance of the inhibition of system, degree of hydration according to the landwaste piece due to the coated ability difference of drilling fluid system inhibition is different, thereby cause the hardness of landwaste piece different, can estimate the coated performance of the inhibition of drilling fluid system.The landwaste piece that embodiment of the present utility model will soak in drilling fluid system is placed in the drilling cuttings lab space 23 of test tank 2, exert pressure by 22 pairs of drilling cuttings lab spaces 23 of pressure space, the landwaste piece sees through chassis 5 and scrapes in the take-up reel 8 by the revolving scraper 30 that is arranged on chassis 5 lower surfaces under pressurized, can collect the quality of the soil paste that penetrates in the landwaste piece by meausring apparatus 10, can according to the parameters such as quality of the soil paste that penetrates in the pressure size in the pressure space 22 and the landwaste piece, finish the evaluation to the coated performance of inhibition of drilling fluid system.If observe reach capacity time of force value of 22 applied pressure values of pressure space shortlyer by tensimeter 61, illustrate that the hardness of the slug after soaking is larger, the coated ability of the inhibition of drilling fluid system is just stronger.In addition, when the applied pressure value reached capacity force value, the quality of the landwaste piece of extrusion test tank was lower, illustrated that the hardness of the landwaste piece after soaking is larger, and the coated ability of the inhibition of drilling fluid system is stronger.
In sum; it below only is preferred embodiment of the present utility model; be not be used to limiting protection domain of the present utility model; therefore; all any modifications of within spirit of the present utility model and principle, doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
