Abstract
The invention discloses a calcium aluminate acidproof ceramic fracturing propping agent and a preparation method thereof. The calcium aluminate acidproof ceramic fracturing propping agent is prepared from the following raw materials in percentage by weight: 60 to 90 percent of alumina, 10 to 40 percent of calcium carbonate and 0 to 10 percent of sintering aid, wherein the sintering aid is one or more of titanium dioxide, boric acid and magnesium oxide. The preparation method comprises the following steps of: (1) putting the raw materials into a ball milling device according to the proportion, and performing ball milling for 24 to 48 hours; (2) preparing the raw materials obtained in the step (1) into semi-finished particles; and (3) sintering the semi-finished particles obtained in the step (2) at the temperature of between 1,300 and 1,600DEG C for 1 to 3 hours, and cooling to room temperature. The process is simple, the calcium carbonate is decomposed at high temperature to form calcium oxide, and the calcium oxide and the alumina are fully reacted to generate stable calcium aluminate. The calcium aluminate has higher acid resistance and prevents other components of the finished product from being corroded by acid liquor, so that the acid resistance of the finished product is greatly improved.
Description
Technical field
The present invention relates to a kind of calcium aluminate acidproof ceramic fracturing propping agent and preparation method thereof.
Background technology
Fracturing propping agents are proprietary materials necessary in the oil-gas field fracturing operation, are used for supporting rock seam, for the circulation of hydrocarbon flow provides the passage of hypertonicity, keep high flow conductivity, improve oil and gas production.Acid resistance is very important indexs of fracturing propping agents, and to fracturing effect, the work-ing life of propping agent and the flow conductivity of oil gas all have material impact.Present domestic most producers are many to be main raw material with bauxitic clay or using industrial solid waste, cooperate other inorganic material to produce fracturing propping agents, the product of producing generally contains the silicon composition, and these compositions can react with hydrofluoric acid to a certain extent, generate a series of compounds such as silicon tetrafluoride, make acid solution to the propping agent internal penetration, its acid resistance is reduced greatly.The oil and gas industry standard SY/T5108-2006 that implemented on January 1st, 2007 decreases to the acid resistance of fracturing propping agents, but finds through our investigation test, and the higher situation of the acid solubility of homemade ceramic fracturing propping agent is still more general.
Summary of the invention
The objective of the invention is provides a kind of calcium aluminate acidproof ceramic fracturing propping agent and preparation method at the general higher present situation of the acid solubility of present homemade fracturing propping agents.
The raw material weight per-cent of calcium aluminate acidproof ceramic fracturing propping agent is aluminum oxide 60-90%, lime carbonate 10-40% and sintering agent 0-10%, and the weight percent sum of aluminum oxide, lime carbonate and sintering agent is 100%; Sintering agent is one or more in titanium dioxide, boric acid, the magnesium oxide.
Concrete steps are:
(1) raw material weight per-cent is aluminum oxide 60-90%, lime carbonate 10-40% and sintering agent 0-10%, and the weight percent sum of aluminum oxide, lime carbonate and sintering agent is 100%; Sintering agent is one or more in titanium dioxide, boric acid, the magnesium oxide; Raw material was put into the ball mill device ball milling 24-48 hour by above-mentioned ratio of components;
(2) (1) step gained feedstock production is become the work in-process particle;
(3) with (2) step gained work in-process particle 1300 ℃-1600 ℃ sintering 1-3 hour, cool to room temperature gets final product.
According to testing by the SY/T5108-2006 recommend method, finished acid solubleness of the present invention has reached the requirement of industry standard between 1.0-3%.
Technology of the present invention is simple, and lime carbonate at high temperature decomposes the generation calcium oxide, and calcium oxide and aluminum oxide fully react and generate stable calcium aluminate.Calcium aluminate has stronger acid resistance, and other component of protection finished product is avoided the erosion of acid solution, has improved the acid resistance of finished product greatly.
