Abstract
The invention relates to a method for harmless treatment of drilling well waste mud. The method comprises the following steps of: firstly adding 150-250 mg/l of colloid destabilizing agent to the waste mud; fully stirring for 1-2 h; then adding 90-300 mg/l of ion settling agent to the waste mud; stirring for 1-3 h and adding 1-3 mg/l of adsorption flocculant; stirring for 1-3 h and standing for 1-2 d; then adding a solidifying agent accounting for 10-40% of total weight of the waste mud to the drilling well waste mud, wherein the solidifying agent is prepared by grinding, stirring and mixing 50-70% of coagulator, 10-25% of adsorbent and 15-35% of calcium oxide; standing for 10-20 d after the solidifying agent is added; and solidifying the drilling well waste mud to form a condensate. The method can solidify the drilling well waste mud with high water content, high organic matter and many harmful substances and has the characteristics of low treatment cost, convenience for use, long stabilization period, no secondary pollution or no damage to soil and meets the environmental protection requirement and the like.
Description
Technical field
A kind of method of handling drilling waste mud, the particularly method of drilling waste mud harmless treatment have been the present invention relates to.
Background technology
Drilling waste mud needs solidification treatment, if handle badly, just produces oozing out of objectionable impurities, pollutes the soil and the groundwater resource of surrounding environment.Make by petroleum well drilling waste slurry to take for a long time and polluted ground, can not obtain environmental transformation and utilization again, improved cost of oil production, reduced the oil field benefit.
Summary of the invention
The application's goal of the invention is to solve the problem that existing drilling waste mud can not well be cured processing, and a kind of method of drilling waste mud harmless treatment is provided.
In order to accomplish the application's goal of the invention, the present invention adopts following technical scheme:
The method of a kind of drilling waste mud harmless treatment of the present invention, wherein: it may further comprise the steps:

The method of the harmless processing of drilling waste mud of the present invention, wherein: peptizer is the sulphoaluminate cement clinker fine powder in the said step (2);
The method of the harmless processing of drilling waste mud of the present invention, wherein: sorbent material is a terra alba in the said step (2).
The method of drilling waste mud harmless treatment of the present invention; Through and drilling waste mud between chemical reaction; Can make that various height are moisture, high organic and drilling waste mud normal setting and harden under lower temperature of containing various objectionable impuritiess; Have the time weak point, water stability is good, and leachable is few, the high remarkable characteristic of intensity.How tame oilfield waste muds such as long celebrating oil field, Karamay oilfield, Southwest Oil sort research and site disposal have been carried out; Development also filters out innocent treatment agent targetedly; Select different innocent treatment agents and basic components for use to the waste mud of different oil recovery factories; And adopt site operation treatment process special in this patent, obtained implementation result both simple and easy to do, that efficient is high, unusual again.Chemical examination detects through environmental administration, all reaches COD≤150mg/l, petroleum-type≤10mg/l, total chromium≤1.5mg/l; Cr6≤0.5mg/l, total As≤0.5mg/l, total pb≤1.0mg/l; Ultimate compression strength reaches the technic index requirement fully greater than 0.7Mpa and above standard, and each item index is all qualified.
The drilling waste mud method for innocent treatment reaches world-class levels, and has obtained the high evaluation of oil production unit and environmental administration.Being treated to the innoxious solidification technology of representative with waste mud, is a new technology of effectively administering the oil well waste.
After the drilling waste mud solidification treatment, effectively prevent oozing out of objectionable impurities, eliminated source of pollution, protected the soil and the groundwater resource of surrounding environment.Make to be taken for a long time to obtain environmental transformation with polluted ground and utilize again, effectively reduce cost of oil production, increased the oil field benefit, have remarkable economic efficiency and social benefit by petroleum well drilling waste slurry.
The curable various height of patent art are moisture, high organic, contain the drilling waste mud of multiple harmful substances.It is low to have processing cost, easy to use, and technology is simple, and stable period is long, and non-secondary pollution does not destroy soil, satisfies characteristics such as environmental requirement.
