Description
Technical field
The present invention relates to a kind of ceramsite propping agent, be specifically related to a kind of non-additive low close ceramsite propping agent and preparation method thereof.
Background technology
Ceramsite propping agent be in oil, gasser recovery process for the critical material of pressing crack construction, and fracturing technique is the main technique measure that improves at present oil, gas production.When carrying out deep well fracturing construction, ceramsite propping agent is filled into and in rock crack, makes high closed fracture treatment, not only can make the rock stratum of oily split, and can also play support crack not stress discharge and closed effect, thereby can keep the high flow conductivity of oil gas; Therefore the quality of ceramsite propping agent performance is that can fracturing yield increasing technique succeed, extend one of key factor of the Oil/gas Well length of service.
Conventionally, the manufacturer of ceramsite propping agent is when producing ceramsite propping agent, starting material are selected fine aluminum alumina, and add different additive, the sintering temperature of ceramsite propping agent is reduced, reach the object reducing costs, improve the intensity of ceramsite propping agent simultaneously, reduce its percentage of damage, as add manganese powder, iron powder, titanium valve, potassium felspar sand, talcum powder etc.; But shortcoming is: 1, to raw-material, have relatively high expectations, must select the bauxitic clay of high-quality, 2, can cause when adding additive raw materials cost to increase.
Bauxitic clay major part is used for doing refractory materials, and its foreign matter content is less, can be divided into superfine, one-level, secondary etc., but also some bauxitic clay foreign matter content is larger according to its aluminium content refractoriness etc., and aluminium content is also lower, and it is less that this part alumina is utilized.
Summary of the invention
The object of the present invention is to provide a kind of non-additive low close ceramsite propping agent and preparation method thereof, solved the problems referred to above, do not add any additive, Easy dosing, steady quality, production energy consumption are low, reach the standard of PetroChina Company Limited..
A kind of non-additive low close ceramsite propping agent of the present invention, does not adopt any additive, and the component of the mixed weight percent content of bauxitic clay forms:

The preparation method of described non-additive low close ceramsite propping agent is as follows:
(1) by after bauxitic clay fragmentation, prepare burden, mix, wear into fine powder;
(2) first add part fine powder to add in nodulizer, after making water fogging, be sprayed on fine powder surface, when fine powder becomes after grain, then add fine powder, add atomized water more simultaneously, finally make work in-process;
(3) after work in-process are dried, calcining, the cooling product that obtains after kiln discharge.
Wherein, broken in described step (1) after particle diameter between 0-5mm, preferred 1-4mm.
Fine powder after grinding in step (1) is 300-500 order.
In step (2), first adding part fine powder amount is the 15-30% fine powder of final product quality; Adding fine powder is the fine powder of final product quality 5-10% again.
Calcining temperature is 1200-1500 ℃, and calcination time is 2-3 hour.
Product can be adjusted according to actual needs by the size of granulator granulation.
Bauxite raw material itself has gone out beyond aluminium, silicon, have the elements such as iron, titanium, calcium, magnesium, potassium, sodium, these elements can affect the high-temperature behavior of bauxitic clay, our this technology is exactly these elements that make full use of in low-grade bauxite, reasonably collocation, make haydite, sintering at a lower temperature, normal temperature strength is larger simultaneously.
Compared with prior art, the present invention has following beneficial effect:
Non-additive low close ceramsite propping agent of the present invention and preparation method thereof, does not add any additive, only utilizes the chemical composition of various raw materials itself, and Easy dosing, steady quality, normal temperature strength are large, and production energy consumption is low, reaches the standard of PetroChina Company Limited..The quality product of preparation reaches the domestic like product that adds additive.
