Method for manufacturing high temperature and high pressure resisting oil well cementing test block through silicon kaolin ceramic microbeads
Disclosed is a method for manufacturing a high temperature and high pressure resisting oil well cementing test block through silicon kaolin ceramic microbeads. The method comprises the steps of the silicon kaolin blind hole hollow ceramic microbeads are prepared, batched, mixed and stirred for size mixing, 55 wt% to 65 wt% of G-level oil well cement, 25 wt% to 35 wt% of the silicon kaolin ceramic microbeads with the particle size of five microns to 50 microns, 5 wt% to 7 wt% of coal ash with the ignition loss of 1.1 percent and the particle size of 20 microns to 50 microns, 1.5 wt% to 2 wt% of calcium oxide with the purity of 99.9 percent, 0.5 wt% to 1.0 wt% of sodium sulfate and 1 wt% to 3 wt% of micro-silicon with the particle size of five microns to 20 microns are mixed, size mixing is carried out on the mixed materials according to the water cement ratio of 0.5-0.7, the mixed materials are poured into a set of two test molds with the length of 53 mm, the width of 53 mm and the height of 53 mm, the test molds are maintained in water bath maintenance boxes at the constant temperature of 52 DEG C for 24 hours and 48 hours respectively, the mixed materials are soaked in cold water for one hour after demolding, and a performance index test is carried out.
