Background technology
Along with the development of oil, Sweet natural gas deep well fracturing technology, the pressure break scale is increasing, and the quartz sand propping agent that generally adopts once is because the material cause flow conductivity is difficult to meet the demands.
Guizhou University of Technology's journal (in August, 2003, the 32nd volume, works such as the 4th phase Chen Ye) has been reported a kind of nonpetroleum fracturing propping agents, has added chromite and TiO
2, the anti-percentage of damage of its 69MPa is 4.10%, is unfavorable for that environmental protection has also increased production cost.
The patent No. is 01108604.1, denomination of invention is the patent of " manufacture method of high-strength ceramic proppant ", a kind of ceramsite propping agent and production method thereof are disclosed, with the light-burned bauxitic clay of 100 weight parts is base-material, add auxiliary materials such as 0.1～3 part in 2～15 parts of clays, 1～10 part of lanthanide metal oxide, 0.3～3 part of Manganse Dioxide and magnesium oxide, have radioactive lanthanide metal oxide owing to added, be unfavorable for environmental protection.The production method of this patent is: will wear into fine powder after major ingredient and the auxiliary material mixing, add and make spherolite by nodulizer after yew is separated, sending into kiln again is that 1100～1500 ℃, sintering time are that 0.5～5 hour processing condition are fired by sintering temperature, the product ultimate compression strength that burns out has reached more than the 69MPa, finished product percentage of damage≤10%, can not satisfy the high strength index request of dark oil well, and but this method owing to adopted the nodulizer granulation, production efficiency is lower.
The propping agent quality of U.S. Carbo company has been represented international most advanced level, owing to adopt the corundum sintering more, though on performance, can meet the demands, raw material sources difficulty, complete processing complexity, facility investment is big, energy consumption is big, cost is high.
Summary of the invention
Technical problem to be solved by this invention provides a kind of high titanium type petroleum oil pressing crack propping agent, the anti-percentage of damage of its 69Mpa≤3.0%, and cost is low and be beneficial to environmental protection.
The present invention also will provide a kind of method of producing above-mentioned high titanium type petroleum oil pressing crack propping agent, and this method is simple to operate, efficient is high.
The technical scheme that technical solution problem of the present invention is adopted is: high titanium type petroleum oil pressing crack propping agent, its Chemical Composition is formed by weight percentage and is comprised: 5～45% high-titanium blast furnace slag, 10～30% high alumina brick, 17～77% bauxitic clays and 4-8% complex sintered dose.
Above-mentioned complex sintered dose weight percent is formed and is comprised: 0～50% rhombspar, 10～75% magnetites and 0～50% kaolin.Blast furnace slag adopts the high-titanium blast furnace slag of industrial waste, and high alumina brick adopts and reclaims high alumina brick.
Produce the method for high titanium type petroleum oil pressing crack propping agent, it may further comprise the steps: 1) that raw material is levigate, make mother bulb with the mist projection granulating system, and again mother bulb is added that the extruding parcel obtains ball blank particle in the coater; 2) with after the ball blank particle drying system drying, enter high temperature kiln and carry out sintering, sintering temperature is controlled at 1100～1400 ℃, and sintering time was controlled at 0.5～4 hour; 3) cooling cooling is carried out surface finish in the rotation of friction drum high speed; 4) be warmed up to 80～100 ℃ again, carry out surface treatment with acidproof organism after, cooling curing.
The invention has the beneficial effects as follows: propping agent batching of the present invention adopts cold trade waste high-titanium blast furnace slag, useless high alumina brick and bauxitic clay, and added complex sintered dose of rhombspar, magnetite and kaolin synthetic, product not only has the advantage of environmental protection and refuse reclamation, production cost is low, and the anti-percentage of damage of product 69Mpa≤3.0% of producing.
Production method of the present invention has not only been improved the inefficient shortcoming of single nodulizer granulation process, and has been improved circularity, sphericity and the turbidity index of propping agent because adopted compound granulation process, makes product have better acid resistance and flow conductivity.Process for treating surface of the present invention makes proppant surface that the slick unreactiveness film of one deck be arranged, and can guarantee that the sour in the course of the work molten rate of propping agent is low, has less resistance to flow, reduces the construction energy consumption, for the gentle outflow of oil provides better hydromeehanics condition.
Embodiment
The invention will be further described below in conjunction with embodiment.
The Chemical Composition of propping agent prescription of the present invention is formed by weight percentage and is comprised: 5～45% high-titanium blast furnace slag, 10～30% high alumina brick, 17～77% bauxitic clays, 4～8% complex sintered dose, wherein complex sintered dose of kaolin that comprises 0～50% rhombspar, 10～75% magnetites and 0～50%, high-titanium blast furnace slag can adopt the high-titanium blast furnace slag of industrial waste, and high alumina brick can adopt the recovery high alumina brick.
High-titanium blast furnace slag has changed the Solid solution structure of product behind the propping agent sintering, utilizes the TiO in the high-titanium blast furnace slag
2Can with the Al in the alumine
