Description

The method for preparing cement clinker with the calcareous mud of oil field oil-containing
Technical field
The present invention relates to the method that the calcareous recycling sludge of a kind of oil field oil-containing is handled, be specifically related to a kind of method for preparing cement clinker with the calcareous mud of oil field oil-containing.
Background technology
Some oil field makes the oil field produce the calcareous mud of a kind of butyraceous for the technology that the etching problem that solves oil field equipment adopts.The calcareous mud of oil-containing is the wet mud of a kind of heavy-gravity, is khaki color.When being hygrometric state, has good plasticity-; But behind the complete drying, the calcareous mud of doing of oil-containing dissolves no longer easily or is dispersed in the water.This is a kind of trade waste, at present non-processor good recipe still.
Summary of the invention
The method that the purpose of this invention is to provide the calcareous mud of a kind of recycling treatment oil field oil-containing prepares cement clinker with the calcareous mud of oil field oil-containing as main raw material.
Technical scheme of the present invention is: prepare the method for cement clinker with the calcareous mud of oil field oil-containing, its step is as follows:
1). with the calcareous mud water of oil field oil-containing flush away sodium;
2). by removing the calcareous mud of sodium oil field oil-containing and unslaked lime, quartz sand, Fe after 900 ℃ of roastings 2O 3Powder is prepared burden and is formed the material of cement slurry, and described each component is respectively the calcareous mud of sodium oil field oil-containing by weight: 35.48-47.39, unslaked lime: 33.74-43.64, quartz sand: 13.50-16.40, Fe 2O 3Powder: 2.2-5.32 carries out sintering behind the combined grinding to material;
3). the grog piece grinding that sinters, the sieve in 0.08mm aperture gets product excessively;
The chemical constitution of removing the calcareous mud of sodium oil field oil-containing after described 900 ℃ of roastings is SiO 26.76-12.07wt%, Al 2O 35.15-15.54wt%, Fe 2O 31.36-5.20wt%, CaO54.31-71.16wt%, MgO9.59-11.37wt%.
The present invention is a main raw material with the calcareous mud of waste oil field oil-containing, and water flush away sodium dries, perhaps with regard to the wet mud formation cement slurry of filling a prescription; Be equipped with some other raw material, successfully prepare ordinary portland cement clinker.This cement clinker is equipped with other material, as flyash, forms Portland fly ash cement, or other ordinary Portland cement.Because the calcareous mud of oil field oil-containing contains relatively large water, oil and CO 2Deng not participating in the material that forms the cement clinker reaction, during the preparation cement slurry, should be according to prescription through the chemical composition design cement slurry of the calcareous mud of oil field oil-containing of 900 ℃ of roastings.By the mud annual production (the calcareous mud of the dried oil-containing of about 2.9 ten thousand steres) of Zhongyuan Oil Field, a small-sized cement factory just can consume light with the 2.9 ten thousand stere dewatered sludges in this every year.The investor not only can win direct economic interests, but also has successfully handled a kind of industrial waste.
Embodiment
The feature of the calcareous mud of oil field oil-containing:
1. states of matter feature
The calcareous mud of oil-containing is the wet mud of a kind of khaki thickness, has good plasticity-, but is dispersed in the water no longer easily when complete drying.This mud contains higher Na, and this component has detrimentally affect to soundness, and belonging to must removing person.The calcareous mud of oil-containing is cleaned with clear water, leave standstill the back and remove supernatant liquor; Oven dry after cleaning 4 times repeatedly.The content of Na and Cl is listed in table 1 in the dried mud in cleaning front and back.Table 1 shows that Na form with NaCl in mud exists, and is removed after the cleaning substantially fully.
