Description
Technical field
The invention belongs to proppant testing field, more particularly to it is a kind of from suspension riverfrac treatment proppant test method.
Background technique
Fracturing propping agents are the critical materials of pressing crack construction, are used to support in the crack of fracturing stratum, effectively will be oily
Conductance enters oil/gas well, to increase substantially oil and gas production and extend the oil well service life.In pressing crack construction, need to take proppant
Band enters in the crack of fracturing stratum, to guarantee that crack is not closed because of the stress release on stratum after pressing crack construction, thus oily
Gas can be entered in oil/gas well by crack, make the output increased of oil gas.
Traditional fracturing propping agents intensity is big, but density is also high, and suspension is poor, is easy precipitating, it is not easy to be carried
Enter into well.In consideration of it, occurring density and water supporting from suspension riverfrac treatment close to even lower than water, energy currently on the market
From suspending in clear water, they only need to use tap water or salt water that can meet pressure break as load fluid in use
The requirement of oil recovery.Suspendability, frictional resistance size in clear water are the important fingers evaluated from suspension riverfrac treatment proppant performance
Mark, and selection use the important evidence from suspension riverfrac treatment proppant.From the suspendability of suspension riverfrac treatment proppant
It is bad, then it is easy precipitating, is not easy to be carried into well, in order to more effectively make fracturing propping agents reach the target position of well,
It also needs to prepare carrying liquid during pressure break.From suspension riverfrac treatment proppant, frictional resistance easily causes greatly proppant transport in water
Difficulty is easy to happen phenomena such as suppressing pump, blocked portion.
Suspendability, the frictional resistance for needing first to measure proppant are being selected from before suspension riverfrac treatment proppant, to determine from outstanding
Can floating riverfrac treatment proppant be carried into well, but the also method without standard is to from suspension riverfrac treatment proppant at present
Suspendability, frictional resistance is measured.
Summary of the invention
The purpose of the present invention is to provide one kind from suspension riverfrac treatment proppant test method, and to solve, at present there is no marks
The problem of quasi- method is measured suspendability, the frictional resistance from suspension riverfrac treatment proppant.
In order to achieve the above object, base case of the invention are as follows: it is a kind of from suspension riverfrac treatment proppant test method,
From the suspendability of suspension riverfrac treatment proppant, specific step is as follows for test:
(1) lower layer height of 20 grams of proppants in the 100ml plastic cylinder equipped with 100ml water is measured, bed height is obtained
Spend h；
(2) measure 20 grams of proppants accounted in the proppant that suspends at the middle and upper levels of 100ml plastic cylinder equipped with 100ml water it is total
The mass ratio of proppant obtains comparing b from suspension；
(3) it calculates from outstanding composite index Zz, * 20/ (h/10) * 5.3 of Zz=(1-b).
From the frictional resistance of suspension riverfrac treatment proppant, specific step is as follows for test:
1) coefficient of friction resistance for measuring clear water, is denoted as λWater；
2) 50 grams of proppants are weighed to pour into 500ml glass, then 400 grams of clear water are added in a reservoir, are stirred 1 minute
Afterwards, it static 10 minutes, being stirred for 1 minute, filters out water after static, the water for measuring 280ml filtering is tested on lubricity tester,
The numerical value obtained is the coefficient of friction resistance of sample, is denoted as λSample；
3) difference ratio-drag reducing efficiency of the coefficient of friction resistance of proppant and clear water is calculated,
The beneficial effect of this base case is:
1, the effect of proppant from suspension is the proppant that upper layer has complete suspension and lower layer to have partial suspended, is integrated from outstanding
Index is that combine the upper and lower to calculate is a comprehensive index, and engineering significance is the reality of proppant in water
Border bulk density, basic and water density is very close to this just explains the proppant being prepared 2 well from the point of view of resin
Why can suspend in the case of several apparent density of point, the quality of suspension effect, also can quantitative assessment, it is smaller from outstanding composite index,
The suspendability for representing proppant is better.
2, the method advantage of this friction test is that test method is simple, high-efficient, and instrument cost is not high, and can phase
To the frictional resistance of the load fluid of accurate evaluation proppant, reliable data supporting is provided for pressing crack construction.
Further, specific operating procedure in the step of test is from the suspendability of suspension riverfrac treatment proppant (1) are as follows:
100ml clear water is poured into 100ml plastic cylinder, is weighed 20 grams of proppants and is poured into graduated cylinder, covers the graduated cylinder mouth amount of then picking up
It is reversed 10 times above and below cylinder, it is static to reverse 10 times up and down after the same method after ten minutes, lower layer's branch in graduated cylinder is tested after static
The height of agent is supportted, is bed height h.The mattress height of lower layer is also to evaluate an important indicator of proppant suspendability, Shen
It asks someone to find by many experiments, by the state modulator of test in above-mentioned numerical value, data that are easy to operate and obtaining are more quasi-
Really.
Further, specific operating procedure in the step of test is from the suspendability of suspension riverfrac treatment proppant (2) are as follows:
In the 100ml plastic cylinder equipped with 100ml water, weighs 20 grams of proppants and pour into graduated cylinder, cover the graduated cylinder mouth amount of then picking up
Cylinder reverses 10 times up and down, static to reverse 10 times up and down after the same method after ten minutes, the support that upper layer suspends after static
Agent pours out, filters, dries that weigh up quality be m, calculates suspension ratio b=m/A*100%.It suspends than being to evaluate proppant in water
Upper layer suspension amount accounts for the percentage of total proppant, using above-mentioned detection method, more true, accurate can obtain suspension
Than.
