Description
Technical field:
The present invention relates to a kind of be in the method for the dark high-strength petroleum fracturing propping agent of oil well production.
Background technology:
Petroleum fracturing propping agent is the successful key that oil fracturing Technology can be brought back to life. Petroleum fracturing propping agent is the upholder making depths, stratum rock fracture keep state of splitting. In use, propping agent is mixed in fracturing liquid, utilizes high pressure tactics to inject deep layer rock fracture and support rock stratum, to improve oil rate, increase crude production rate. At present, the pressure break ceramsite sand intensity of domestic employing is general lower, can only be used for shallow-layer oil mining. If these propping agents are used in middle-deep well oil production, the various corrosion born in the huge pressure in rock stratum and ground environment will be difficult to, can be a large amount of broken, 20��40 order 69mpa percentages of damage are generally 4��8%, it is difficult to the requirement of dark oil well in meeting. Adopt alundum goods in the world (such as the U.S.) more, although but this kind of goods can meet requirement on physicochemical property, but raw material sources are difficult, and complete processing is complicated, and energy consumption is big, cost height.
Summary of the invention:
Technical problem to be solved by this invention is: the method for phosphoric acid block salt, abundant bauxitic clay ore raw material and the special auxiliary material providing a kind of utilization to scrap dark high-strength petroleum fracturing propping agent of oil well production in being.
The present invention is the technical scheme that technical solution problem is taked:
Utilizing the useless brick of phosphoric acid salt to produce a method for high-strength petroleum fracturing propping agent, each raw materials by weight proportioning is as follows: phosphoric acid salt gives up brick 40%, bauxitic clay ore raw material 50%, Suzhou soil 3%, manganese powder 3%, rhombspar 2%, talcum powder 2%;
Concrete production stage is as follows:
1. prepare burden: prepare burden by above-mentioned weight percent;
2. broken: different material to be carried out respectively fragmentation, after being first broken into 50mm��60mm, then is broken into 8mm��10mm;
3. fine grinding: the material after fragmentation is sent into mixed mill 60��80min in ball mill, mixes and wear into 350��400 even fine powders of order;
4. granulation: delivered to by the material after fine grinding in each tablets press and carry out granulation, dries after granulation at the temperature of 60��120 DEG C, until moisture < 3% in spherolite;
5. high-temperature calcination: the card nailing neps after granulation is sent in rotary kiln and carries out high-temperature calcination, high-temperature calcination temperature: 1200��1250 DEG C, calcination time: 75��90min;
6. screen analysis: the high-strength petroleum fracturing propping agent burnt till is carried out check analysis, screening, is put in storage by automatic weighing-packaging machine package test after qualified and waits to sell.
The chemical composition of the useless brick of described phosphoric acid salt is by mass percentage: P2O375��80%, SiO25��7.2%, Fe2O31.1��2.3%, burn and lose < 2.5%.
The chemical composition of described bauxitic clay ore raw material is by mass percentage: Al2O360��70%, SiO27.3��11.4%, Fe2O31.5��2.5%, MgO < 1.0%, CaO < 1.0%, burns and loses < 12��14%.
The present invention innovates proposition and utilizes bauxitic clay ore raw material and the useless brick of phosphoric acid salt to be main raw material, is equipped with special auxiliary material, obtains high-strength petroleum fracturing propping agent, reaches utilization of waste material, cost-saving object.
There are abundant bauxitic clay ore resource and the useless brick resource of phosphoric acid salt in China, and relative price is cheap, for the present invention provides good main raw material resource.
In each auxiliary material:
Suzhou soil: can increase blank plasticity-, it is to increase base ball intensity, reduces goods base ball breakage rate;
Manganese powder: owing to its ionic radius is close with 3 valency aluminum ion radiuses, very easily replaces aluminum ion and forms solution body and cause lattice distortion;
Rhombspar: the sintering temperature that can greatly reduce goods, it is to increase liquid phase surface tension, it is to increase sintering degree, widens the scope of its sintering, simultaneously due to its under 1000 DEG C of temperature condition can with Al2O3Form folder spar, it is in crystal boundary place outside being wrapped in, works as Al2O3During grain growth, it is subject to crystal boundary place foreign matter obstruction, and crystal boundary to be moved further and just to must be over spinel phase, it is necessary to paying bigger energy could realize, and thus stops Al2O3Growing up of crystal grain, makes goods obtain microlitic structure, greatly improves proppant strength;
Talcum powder can obviously provide support the surface flatness of agent.
The batching foundation of the present invention: for meeting molten mass viscosity, temperature, easily crystallization and shrink the requirements such as little, the present invention adopts CaO-MgO-MnO2-Al2O3-SiO2System, can finally precipitate out ��-corundum crystalline phase as principle, point selection is in the chemical composition close to ��-corundum.
The high-strength petroleum fracturing propping agent that the present invention produces, is possible not only to the production cost obviously reducing propping agent, and can greatly improve the intensity of petroleum fracturing propping agent, and its every performance index all meet or exceed national standard.
