Method for treating potassium ammonium group drilling fluid rock debris

Abstract

The invention provides a method for treating potassium ammonium group drilling fluid rock debris. The method comprises the step that a rock debris gel breaker and a rock debris solidification agent are sequentially added into rock debris generated in the potassium ammonium group drilling fluid drilling process to be stirred and mixed. Treatment debris obtained through the treatment method can reach the standard request I of standards for pollution control over the storage and disposal site for general industrial solid wastes. The solidification stabilization technology is adopted, the gel breaker is adopted for carrying out breaking stabilization on the rock debris, then the solidification agent is adopted for carrying out solidification and closing on the rock debris, and the method has the advantages that the treatment process is simple and the treatment effect is stable.

Description

technical field [0001] The invention relates to the technical field of drilling solid waste treatment, in particular to a potassium ammonium-based drilling fluid cuttings treatment method. Background technique [0002] Potassium-ammonium-based drilling fluids are widely used in oil and gas exploration and development, especially in Xinjiang and Inner Mongolia, because of their strong ability to inhibit clay hydration and dispersion, strong ability to control harmful solid phases, and good shear dilution. The common formula of potassium ammonium-based drilling fluid is: 3%~4% sodium bentonite, 0.2%~0.3% potassium hydroxide, 0.3%~0.5% potassium polyacrylate, 0.5%~1% hydrolyzed polyacrylonitrile ammonium salt, 2%~ 3% sulfonated phenolic resin, 1%-2% sulfonated lignite, 2%-3% non-fluorescent anti-slump agent, 2%-6% graphite powder. The cuttings produced during the drilling process carry a large amount of drilling fluid, which is easy to pollute the environment, and has the char...

Problems solved by technology

With the improvement of my country's environmental protection regulations, the current consolidation stabilization treatment formula can no longer meet the requirements of potassium ammonium-based drilling fluid cuttings treatment, and there are defects such as high pH after treatment, excessive COD, and large dosage.
