Description
Technical field
The present invention relates to a kind of preparation methods of high mating type film-coated ceramisite proppant material, belong to proppant material technology
Field.
Background technology
In recent years, with the fast development of world economy and science and technology advance by leaps and bounds, oil, natural gas demand
Amount is still high.Hydraulic fracturing technology is the important means for making well production increment, is widely used to various oil gas well developments,
During hydraulic fracturing job, the effect of proppant is most important.Proppant is low-permeability oil gas well and shale gas reservoir exploitation
The critical material of pressing crack construction, is a kind of product with high added value feature, and performance quality decides hydraulic fracturing technology
Win or lose, also contribute to the length of service of oil/gas well.Hydraulic fracturing technology tests successfully so far in the U.S., nearly 70 years
In evolution, larger variation also has occurred in the proppant material as pressure break, wide till now from the quartz sand of beginning
The general sintering ceramsite used.With the continuous exploitation of Low permeable oil and gas reservoirs, the performance of ceramsite propping agent also proposed prodigious
It is required that not only needing higher intensity, also there is certain limitation to its density.Therefore, the correlation of ceramsite propping agent is furtherd investigate
Content can be that hydraulic fracturing technology injects new vitality, and then creates immeasurable value to petroleum industry.
Ceramsite propping agent is that the spherical particle prepared based on traditional pottery adds mainly using bauxite as raw material
Add other auxiliary materials, is a kind of artificial stays agent through pelletizing, being sintered.Since the nineties in last century, people's development is simultaneously extensive
It is applied in deep low-permeability oil-gas Layer hydraulic fracture mining.The advantages of ceramsite propping agent：1）Chemical stability is good, salt resistance
Corrosion resistance is high；2）Intensity is high；3）Under identical clossing pressure, the percentage of damage of ceramsite propping agent is more lower than quartz sand,
Flow conductivity is then than quartz sand higher；4）Increase with clossing pressure or the extension of pressure-bearing time, percentage of damage equally than
Quartz sand it is low, and the rate of regression of its flow conductivity is also more more slowly than quartz sand proppant.Resin coating can not only carry
High intensity, and overlay film rear support agent flow conductivity is strong, it is possible to reduce the phenomenon that proppant embedment stratum.However at present in relation to covering
The research report of film ceramsite propping agent is also less, mainly with bauxite etc. for primary raw material, after being coated using novolac epoxy resin,
It significantly improves the breaking strength of haydite, or with oil shale waste, aluminium rock soil is to utilize phenolic resin and epoxy resin for raw material
Mix overlay film.Therefore, it is practicable to improve the intensity of haydite using resin coating.But existing resin coating leads to haydite
Resin and haydite combine poor in material, cause ceramsite propping agent material property poor, are carved so carrying out effectively improveing to it
Do not allow to delay.
Invention content
The technical problems to be solved by the invention：Poor, influence is combined for existing film-coated ceramisite proppant coating
The problem of material mechanical performance, provides a kind of preparation method of high-compatibility magnesium-based Biocomposite material.
In order to solve the above technical problems, the technical solution adopted by the present invention is：

0.2 part of magnesia, 3~5 parts of calcium oxide, 0.1~0.5 part of potassium oxide are placed in ball grinder, are sieved to obtain the powder that is sieved in ball milling,
Sieving granulating powders are handled and are sieved, matrix pellet is obtained；
（3）Matrix pellet is dried to constant weight, dried base pellet is obtained and is placed in high temperature sintering furnace, sintering processes are stood cold
But to room temperature, ceramsite material is obtained；Ceramsite material is added in sol solutions, stands, filter cake is collected by filtration, it is quiet by filtration cakes torrefaction
It sets and is cooled to room temperature and collects and to obtain coating modification ceramsite material；
（4）Coating modification ceramsite material is placed in Muffle furnace, is warming up to 250~260 DEG C by 5 DEG C/min, isothermal holding is stood
It is cooling, obtain preheating ceramsite material；
（5）Count in parts by weight, weigh respectively 45~50 parts of phenolic resin 2402,3~5 parts of silane resin acceptor kh-550s, 15~
20 parts of epoxy resin E-51 and 25~30 parts of preheating ceramsite materials are placed in blender, are stirred juxtaposition and are stood at room temperature admittedly
Change, atoleine is added before the agglomerating caking of particle, is stirred and cools down sieving, you can is prepared into the high mating type
Film-coated ceramisite proppant material.
Step（2）The granulation processing is added to for the powder that will be sieved in sugar coating machine, sprays into the mass fraction of atomization
10% poly-vinyl alcohol solution, molding granulation.
Step（3）The sintering processes temperature is 1250~1300 DEG C.
Step（5）The atoleine additive amount is preheating ceramsite material quality 25%.
Compared with other methods, advantageous effects are the present invention：
（1）Technical solution of the present invention uses potassium permanganate as raw material and prepares gel rubber material containing manganese, by that will contain manganese gel cladding
To matrix haydite surface, since the surface of the filtrate through manganese gel coating modification polishes and has acicular MnO2Crystal, it is interior
Portion is also by surface MnO2Film covers, wherein MnO2There are about 1 μm for film thickness, has not only increased the specific surface area of filtrate, but also makes MnO2Coating with
Ceramic matrix is strong bonded, is effectively improved the bond strength of coating and ceramsite material；
（2）Technical solution of the present invention is by contain manganese gel as boundary layer, being coated to ceramsite material surface, by by high score
Sub- covering material is coated to the surface of gel rubber material containing manganese, since its generation combines and forms stable combination, makes gel containing manganese
Material is modified as boundary layer, effectively improve epoxide resin material haydite particles surface load performance, to improve
Binding performance between material and material.
