Description
Technical field:
The method of the dark high-strength petroleum fracturing propping agent of oil well production in the present invention relates to phosphoric acid block salt that a kind of utilization scraps, abundant bauxitic clay ore raw material and special auxiliary material and being.
Background technology:
Petroleum fracturing propping agent is the resuscitable successful key of oil fracturing Technology.Petroleum fracturing propping agent is to make depths, stratum rock fracture keep the upholder of the state that splits.In use, propping agent is sneaked in fracturing liquid, utilize high pressure tactics to inject deep layer rock fracture and support rock stratum, to improve oily rate, increase crude production rate.At present, the pressure break ceramsite sand intensity of domestic employing is generally lower, can only be for shallow-layer oil mining.If these propping agents are used in middle-deep well oil production, will be difficult to bear the various corrosion in the huge pressure in rock stratum and ground environment, can be a large amount of broken, 20～40 order 69mpa percentages of damage, generally 4～8%, are difficult to the requirement of dark oil well in meeting.(as the U.S.) in the world adopts alundum goods, although this goods on physicochemical property, can meet the demands, but raw material sources are difficult, complete processing complexity, and energy consumption is large, cost is high.
Summary of the invention:
Technical problem to be solved by this invention is: provide phosphoric acid block salt that a kind of utilization scraps, abundant bauxitic clay ore raw material and special auxiliary material be in the method for the dark high-strength petroleum fracturing propping agent of oil well production.
The present invention is that the technical scheme that technical solution problem is taked is:
A method of utilizing the useless brick of phosphoric acid salt to produce high-strength petroleum fracturing propping agent, each raw materials by weight proportioning is as follows: the phosphoric acid salt brick 40% that gives up, 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: by above-mentioned weight percent, prepare burden;
2. broken: different material to be carried out respectively to fragmentation, be first broken into after 50mm～60mm, then be broken into 8mm～10mm;
3. fine grinding: the material after fragmentation is sent into mix grinding 60～80 min in ball mill, and mix grinding becomes the even fine powder of 350～400 order;
4. granulation: the material after fine grinding is delivered in each tablets press and carried out granulation, dry at the temperature of 60～120 ℃ after granulation, until moisture < 3% in spherolite;
5. high-temperature calcination: the card nailing neps after granulation is sent into and carried out high-temperature calcination, high-temperature calcination temperature in rotary kiln: 1200～1250 ℃, calcination time: 75～90min;
6. screen analysis: the high-strength petroleum fracturing propping agent burning till is carried out to check analysis, screening, for sale by automatic weighing and packing machine package test warehouse-in after qualified.
The chemical composition of the useless brick of described phosphoric acid salt is by mass percentage: P
