Abstract
The invention discloses a preparation method of a acid resistant ceramsite fracturing propping agent. Raw materials contain: by weight, 70-90% of alumina, 0.1-10% of a phosphor compound and 0-30% of a sintering agent, wherein the sum of the mass percentage of the raw materials is 100% and the sintering agent contains one or more compounds selected from barium, calcium, magnesium and boron. The preparation method provided by the invention comprises the following steps of: putting the raw materials into a ball milling device and carrying out ball milling for 12-48 hours; drying the obtained slurry at the temperature of 60-120 DEG C for 3-12 hours; preparing the obtained raw material into a spherical granular green compact by a molding technology; sintering the obtained granular green compact in a Si-Mo furnace at the temperature of 1400-1600 DEG C, keeping warm for 0.5-3 hours, and cooling with the furnace temperature. Tested according to the SY/T5108-2006 recommended method, the acid solubility of the finished product is less than 2% and greater than 0.5%, which reaches the standard requirement in the industry (the allowable value of the acid solubility is less than or equal to 5%). The preparation method provided by the invention requires general industrial equipment and simple process, and is beneficial to industrial production.
Description
Technical field
The present invention relates to a kind of preparation method of acidproof ceramic fracturing propping agent.
Background technology
Fracturing propping agents are a kind of proprietary materials of oil gas fracturing technique, are used for supporting rock seam, for the circulation of hydrocarbon flow provides the passage of hypertonicity, keep high flow conductivity, thus improve oil and gas production, prolong the oil gas well the length of service, reduce the oil recovery pneumatolytic this.The quality of fracturing propping agents quality is the key that can oil-gas mining succeed, and wherein acid resistance is one of important indicator.The propping agent that is pressed into the rock seam is wanted to bear various erosion medium resistance in the ground environment, in order to avoid the cracked obstruction pressure break passage in back that is corroded stops oil gas to flow out.Aspect the acid resistance of propping agent, all exist same problem-acid resistance poor both at home and abroad.Present domestic most propping agent manufacturer is main raw material with bauxitic clay or using industrial solid waste, and the propping agent acid solubility that cooperates other inorganic materials to produce is higher, is difficult to satisfy the requirement of oil-gas mining, influences the output of oil-gas field.The quality of U.S. Carbo company propping agent has represented international most advanced level, but the acid solubility of its HSP product also can only reach 3.5%.Therefore, the acid resistance of raising propping agent is the matter of utmost importance that the oil and gas exploitation industry must solve.
Summary of the invention
The purpose of invention is exactly at the general higher present situation of domestic and international propping agent acid solubility, and a kind of preparation method of acid-resistant pressing crack supporting agent is provided.Adopt industrial raw material, by adding the compound of phosphorus, the acidproof ceramic fracturing propping agent of preparation acid solubility between 0.5-2%.
Concrete steps are:
(1) raw materials quality per-cent is: the compound 0.1-10% of aluminum oxide 70-90%, phosphorus and sintering agent 0-30%; The mass percent sum of raw material is 100%, sintering agent be barium, calcium, magnesium and boron compound one or more;
(2) step (1) raw material being put into ball mill device carried out ball mill mixing 12-48 hour;
(3) step (2) gained slurry was dried 3-12 hour under 60 ℃ of-120 ℃ of temperature;
(4) with step (3) gained raw material through moulding process, make the form of spherical particles green compact;
(5) with step (4) gained particulate green 1400 ℃ of-1600 ℃ of sintering in silicon molybdenum stove, be incubated 0.5-3 hour, with the furnace temperature cooling namely.
According to the SY/T5108-2006 recommend method finished product is tested, acid solubility reaches the requirement (permissible value of acid solubility≤5%) of industry standard between 0.5-2%.
The present invention adopts general industry equipment, and technology is simple, be conducive to suitability for industrialized production.
