Abstract
One environment protection type high-strength resin coated propping agent of the present invention, including aggregate, environmental protection type resin, catalyst, dispersant, desiccant, anticaking agent, described environmental protection type resin includes the material containing terminal hydroxy group, containing the material of isocyanate groups.On the basis of retaining conventional proppants effect, it is possible to preferably provide protection to environment and human body, more save the energy, cost-effective, the most also there is intensity high, broken low advantage.
Description
Technical field
The invention belongs to exploitation of oil-gas field technical field, belong to the compositions for strengthening rupturing, such as, be used for protecting
Hold the propping agent combination rupturing unlatching, be specifically related to a kind of environment protection type high-strength resin coated propping agent.
Background technology
Conventional and unconventionaloil pool production technique has developed to obtain relative maturity, now the exploitation skill of China in north america
Art is achieved with significant progress.Overlay film proppant is widely used in fracturing is constructed, but because fracturing is constructed
During use fracturing fluid in a large number, work progress has substantial amounts of fracturing fluid recovery (backflow) to ground, the pollution of surface water can be caused.
The material that the most domestic overlay film proppant uses is substantially phenolic aldehyde, epoxy resin, and these resins are producing
With application process can produce free phenol, the poisonous and harmful substance such as free aldehyde.And phenolic aldehyde, the solidification of epoxy resin needs to add respectively
Planting firming agent, most common of which firming agent is to use hexamethylenamine, and hexamethylenamine at high temperature produces substantial amounts of ammonia, to environment
Work the mischief with staff.A lot of pressing crack constructions return the fracturing fluid of row because of above-mentioned reason meeting serious environment pollution.And it is domestic
Traditional overlay film proppant broken in the case of the overlay film of low resin content, sour molten a lot of index such as grade does not reaches requirement.Based on above-mentioned
Background, develops a kind of overlay film proppant product with environmental protection characteristic the most necessary.
Summary of the invention
It is an object of the invention to provide a kind of environment protection type high-strength resin coated propping agent, have safety and environmental protection produce and
The feature used, reduces the pollution to environment.
For reaching above-mentioned purpose, the technical scheme is that a kind of environment protection type high-strength resin coated propping agent, including
Aggregate, environmental protection type resin, catalyst, dispersant, desiccant, anticaking agent, described environmental protection type resin includes containing terminal hydroxy group
Material, containing the material of isocyanate groups.
When using technique scheme, on the basis of retaining conventional proppants effect, it is possible to preferably to environment and people
Body provides protection, more saves the energy, cost-effective, the most also has intensity high, broken low advantage.With conventional resins overlay film
Proppant is compared and is also had the advantage that
The feature of environmental protection: conventional resins overlay film proppant phenolic aldehyde, epoxy resin overlay film can produce during high temperature production, trip
From phenol, free aldehyde, the poisonous and harmful substance such as ammonia, and the present invention uses the environmental protection type resin can safety in the case of low temperature overlay film
The production of environmental protection.
The properties of product of same resin amount: in the case of same amount of resin coating, the present invention's is close at body, depending on close, broken
The index performance such as broken is more excellent.
Energy-conservation: the coated temperature of conventional resins overlay film proppant at 230 DEG C, the coated temperature of the present invention 60 DEG C～150 DEG C.
From the point of view of energy resource consumption, the present invention has the biggest advantage.
Change to aggregate outward appearance: conventional resins overlay film proppant passes through high-temperature resin overlay film, the easily color and luster to aggregate,
The size of particle diameter changes, and the present invention uses the film covering method of liquid resin low temperature can preferably protect aggregate color and luster, particle diameter
Size.
The action effect of low resin content is obvious: in the case of amount of resin is less than 1%, conventional resins overlay film proppant is to bone
The change that material crushes is the most little, and the present invention can be can effectively improve the broken situation of aggregate in the case of low resin content.
Improvement project further, the described material containing terminal hydroxy group includes polyalcohols, polyethers, aromatic series alcohols, gathers
A kind of or two kinds in them in esters, castor oil modified polyhydric alcohol and above mixture.
Further improvement project, the described material containing isocyanate groups includes methyl diphenylene diisocyanate, different
Isophorone diisocyanate, polyphenyl polymethylene polyisocyanates, the different hydrogen acid ether (hydrogen acid ester) of toluene two, hexamethylene diisocyanate,
One in PPDI, 1,4 cyclohexane diisocyanates, tetramethyl m-xylylene diisocyanate or it
In two kinds and above mixture.
Improvement project further, the described material containing terminal hydroxy group and the weight ratio of the material containing isocyanate groups
It is 0.3～5.
Improvement project further, described aggregate includes haydite, low-density ceramsite, ceramic material, quartz sand particle, Semen Juglandis
A kind of or two kinds in them in shell, resin material, elastomeric material, glass material and above mixture.
Improvement project further, the weight of described environmental protection type resin is the 0.25%～5% of aggregate weight.
Further improvement project, described catalyst include a kind of in organic lead plumbate, organotin, polyethers or in them two
Plant and above mixture.
