Description

The colloid intensity measuring device

One, technical field

The utility model belongs to be measured or technical field of measurement and test, particularly relates to a kind of by means of the chemistry of measuring material or physical property is tested or the determining instrument of analysis of material.

Two, background technology

China's oilfield chemistry water-plugging technique was used at the scene from the 1950's, existing so far more than 50 year history.Be to use the grout water blockoff at first, developed oil base cement, milk of lime, resin, active viscous crude etc. subsequently, the sixties, the seventies, polymer gel and soluble silicate gel began in field use based on resin.The intensity of polymer gel and soluble silicate gel is very important parameter in the water blockoff design process, it also is the important indicator of estimating the water shutoff agent performance, generally estimate frozen glue, gel-like water shutoff agent intensity now with ocular estimate, because it is very big that this method is subjected to the influence of observer's individual difference, the resultant error of estimating out is very big.All there are certain drawback in polymer gel, silicate gel strength detection method commonly used both at home and abroad, such as API observation, pen. method, falling ball method etc. all can only more various qualitatively colloid intensity power, can't provide intensity data accurately.In addition, because high-strength gel can't adopt the variation of dependence moments of torsion such as rotational viscosimeter to represent that the instrument of colloid intensity carries out strength detection, and it is complicated to adopt core to estimate breakthrough pressure gradient process.At present, also there is not a cover ripe relatively, easy and simple to handle, can the quantitative measurement polymer gel, the method and the instrument of silicate gel isocolloid intensity.

Three, summary of the invention

The purpose of this utility model provides a kind of colloid intensity measuring device, solved polymer gel, the problem that the silicate gel quantification of intensities is measured, it comprises base, support, the scale folder, slide scale, electronic balance, pallet and sample cup, be provided with support for one jiao at base, support top is connected with slide scale by the scale folder, the gearing mesh that slide scale is coaxial with knob, the slide scale lower end is connected with the standard pressure cap, slide scale guide rail lower end is provided with tuning drive gear and pedal line, on base, be placed with electronic balance successively, pallet and sample cup, the leg of sample cup bottom is corresponding with the limiting hole on the pallet, base has 4 legs, and leg and base spin, and is provided with spirit bubble on base, the utility model is simple in structure, can the quantitative measurement polymer gel, silicate gel, the intensity of similar colloid such as modified starch has easy to usely, makes simple, cheap, advantage such as practical.

Five, embodiment

Below in conjunction with Fig. 1 the utility model colloid intensity measuring device is described further, as shown in Figure 1, it comprises base 9, support 1, scale folder 2, slide scale 4, electronic balance 11, pallet 12 and sample cup 8, be provided with support 1 for 9 one jiaos at base, support 1 top is connected with slide scale 4 by scale folder 2, the gearing mesh that slide scale 4 and knob 3 are coaxial, slide scale 4 lower ends are connected with standard pressure cap 7, slide scale 4 guide rail lower ends are provided with tuning drive gear 5 and pedal line 6, on base 9, be placed with electronic balance 11 successively, pallet 12 and sample cup 8, the leg of sample cup 8 bottoms is corresponding with the limiting hole on the pallet 12, base 9 has 4 legs 13, leg 13 spins with base 9, is provided with spirit bubble 10 on base 9, is mainly used in the mensuration of colloid compressive strength.At first, adjust the leg 13 of base 9, make bubble be positioned at the center of spirit bubble 10; Then, adjust scale folder 2, make slide scale 4 be positioned at the position parallel with pedal line 6; Secondly, rotary knob 3 drives on the slide scale 4 and moves on to the extreme higher position, selects suitable standard pressure cap 7, and sample cup 8 is placed on the electronic balance 11, makes the leg of sample cup 8 bottoms just aim at limiting hole on the pallet 12; Again electronic balance 11 registrations are made zero, slow rotary knob 3, the slide scale 4 that is engaged with by the gear driven coaxial with it at the uniform velocity moves down, the indicated height number L1 of record tuning drive gear 5 when standard pressure cap 7 just touches the colloid upper surface; Continue rotary knob 3, drive slide scale 4 and continue to move down, and the registration of close observation colloid surface and electronic balance 11, recorded electronic balance 11 registration m when colloid surface breaks ₁, the height value L that record tuning drive gear 5 is indicated ₁', the parting pressure of following formula calculated for gel body:

P＝m ₁*g/A

P---colloid parting pressure, MPa;

m ₁--electronic balance registration when-colloid breaks, g;

G---acceleration of gravity, 9.8N/g;
