Production method for manufacturing sintered brick by using water-base mud

Abstract

The invention discloses a production method for manufacturing a sintered brick by using water-base mud. The method comprises the following steps that firstly, waste mud is subjected to solid and liquid separation; supernate is pumped out; solid phase wet mud is obtained; secondly, a curing agent is added into the solid phase wet mud; the solid phase wet mud is cured to form mud cake; then, the mudcake is pressed and shaped to form a wed brick blank; drying is performed; finally, the dried brick blank is fired to form a sintered brick; the abandoned water-base mud is subjected to consolidationtreatment through a dehydrating agent and a flocculating agent; the alkaline corrosion of the mud is reduced; the supernate and the solid phase wet mud of the waste mud can be separated, and are respectively recovered and utilized; liquid is cyclically utilized without outward discharging; the curing agent is added into the solid phase wet mud, so that the character of the solid phase wet mud canbe changed; a sintered brick material with cement characteristics is formed; the outward discharging quantity of the waste mud is reduced; harmful substances in the waste mud are prevented from polluting and destroying environment.

Description

technical field [0001] The invention relates to the technical field of water-based mud, in particular to a production method for making fired bricks by using water-based mud. Background technique [0002] During the drilling process in oilfields, drilling mud can balance formation pressure and lift cuttings. The cooling of the drilling bit, the increase of the drilling speed and the lubrication of the drilling tool have played a very effective role. Therefore, the drilling mud is an indispensable material for the smooth development of the drilling work. In today's continuous development of science and technology, in order to ensure the safety of drilling As the speed of drilling and drilling increases, the types and quantities of chemicals that make up drilling fluids become more and more, and the impact on the environment becomes greater and greater. [0003] With the rapid development of my country's petroleum industry, the pollution caused by drilling operations has beco...

Problems solved by technology

Because dehydration in sludge is relatively large due to its large specific resistance, the existing technology has no obvious effect on sludge dewatering, and the moisture content of sludge after dehydration is still as high as 80%. The method of natural drying or artificial drying to accelerate dehydration requires large investment, high energy consumption and high cost
