Abstract
The invention provides a crush-resistant capacity test method for a resin film-coating proppant. The crush-resistant capacity test method comprises the steps of before or after a crush-resistant capacity test, roasting a resin film-coating proppant sample to completely burn out surface resin; and during weighing, weighing the mass of the sample having a higher mass value and left on a sieve screen instead of the mass of proppant particles falling onto a chassis below the sieve screen, thus effectively avoiding the measurement errors caused by the loss of fine powder in the process of transferring and screening the proppant particles, wherein the obtained data can be used for really and accurately reflecting the crush-resistant capacity of the resin film-coating proppant, thus being higher in reference value and capable of realizing selection of proper fracture film-coating proppants aiming at different application occasions better.
Description
Technical field
The present invention relates to the method for testing performance of resin coated propping agent, belong to the petroleum fracturing propping agent technical field.
Background technology
Fracturing propping agents are critical materials of pressing crack construction, for being supported on the crack of fracturing stratum, effectively oil gas are imported to Oil/gas Well, thereby increase substantially oil and gas production and extend the oil well life-span.Usually; fracturing propping agents are natural sand or the artificial high strength ceramics particle with certain particle size and grating; development along with petroleum industry; in order further to improve the performance of fracturing propping agents; developed novel low frictional resistance propping agent, thereby it intensity and the guide performance of fracturing propping agents have further been improved at the grains of sand or ceramic grain surface film covered resin.
For the evaluation of fracturing propping agents performance, percentage of damage is one of key technical index, is also the important evidence of choice for use fracturing propping agents.At present, the examination criteria of domestic propping agent is all carried out according to SY/T 5108-2006 standard, and the anti-breaking capacity method of testing in this examination criteria is: at first, select the pressure of propping agent performance requirement, by certain mass m
1carry out anti-breaking capacity test with the propping agent of specification in the crushing chamber of standard specification (d=50.8mm); Then, the propping agent after crushing test is poured in the screen cloth of dimension and sieved; Finally, take by falling into the quality m of this propping agent crushed particles on the chassis be positioned at below screen cloth after this screen cloth
5thereby, calculate the percentage of damage of propping agent according to formula (1):
η
1=m

1*100% …………………………………………（1）。
Yet, for the film covered resin propping agent, Many researchers thinks that propping agent can not really improve its anti-breaking capacity after overlay film, and according to industry standard, measured anti-breaking capacity is apparent, concrete reason is: while according to the industry testing standard, the film covered resin propping agent being carried out to anti-breaking capacity test, because the resin molding of this proppant surface overlay film has certain elastic acting force, even if the aggregate of propping agent is broken, under the coating function of resin molding, the propping agent body is can be not thoroughly not broken and the particle of propping agent is coated by resin molding yet, while causing adopting screen cloth to be sieved, this part propping agent particle can't be gone out in screen analysis, and then the propping agent particle quality fallen on following chassis by screen cloth recorded in causing testing is less than normal, the data that record can not truly reflect the anti-breaking capacity of overlay film propping agent.
In addition, the propping agent particle is the process that drops into chassis from screen cloth and in the process of weighing is carried out to together with the propping agent particle on it in chassis, fine powder in particle easily disperses, cause the loss of a small amount of fine powder, the quality of the crushed particles that causes weighing to obtain can not be truly and is reflected exactly the anti-breaking capacity of propping agent; Need this particle total amount of weighing relatively seldom, on this basis, the loss of a small amount of fine powder can further enlarge the error of above-mentioned weighing in addition.
Summary of the invention
First technical matters that the present invention will solve is, when available technology adopting industry standard method is measured the anti-breaking capacity of resin coated propping agent, because the resin molding of this proppant surface overlay film coats the particle of propping agent, cause the test result can not be truly and reflect exactly the anti-breaking capacity of resin coated propping agent; And then provide a kind of method of testing that can accurately reflect the anti-breaking capacity of resin coated propping agent.
Second technical matters that the present invention will solve is, when available technology adopting industry standard method is measured the anti-breaking capacity of resin coated propping agent, in the process that the propping agent particle is shifted and sieves, easily cause the loss of a small amount of fine powder, cause the described percentage of damage error of calculating larger, and then a kind of method of testing that can effectively avoid losing due to fine powder the anti-breaking capacity of resin coated propping agent of the measuring error caused in the process that the propping agent particle is shifted and sieves is provided.
The anti-breaking capacity method of testing of resin coated propping agent of the present invention, it comprises the following steps:
