Method and device for generating water-based drilling waste residue curing treatment formula
Technical Field
The invention belongs to the field of solid waste treatment, and particularly relates to a method and a device for generating a water-based drilling waste residue curing treatment formula.
Background
In the process of oil and gas reservoir development, solid wastes such as waste drilling fluid, drill cuttings and the like generated in drilling engineering have the characteristics of large quantity of pollutants, high concentration, complex components, high treatment difficulty and the like, and if the solid wastes are not treated, the solid wastes are directly discharged to cause serious threat and influence on the ecological environment. Therefore, the method has important practical significance for realizing green and environment-friendly drilling by performing harmless and recycling treatment on the drilling solid waste.
At present, solidification landfill is one of common drilling solid waste treatment and disposal modes, and the method has the characteristics of low cost, simple operation, quick effect and easy transportation. During solidification treatment, due to the fact that pollution components of generated drilling cuttings and waste drilling waste residues are dynamically changed due to the geological structure difference of oil and gas reservoirs and the difference of drilling fluid systems adopted in different wells or different drilling stages of the same well, and the change range is large, different solidification formulas need to be optimally designed for solid waste residues with different pollution degrees during solidification treatment of the drilling waste residues, and the drilling waste residues can meet the requirements of I/II of the pollution control standard of the general industrial solid waste storage disposal site GB18599-2001 after solidification treatment. At present, in order to obtain a qualified curing formula, technicians generally detect the waste residue moisture of the original drilling waste residue and pollution control indexes, namely pollution indexes such as COD, pH, chroma, oil content, heavy metals and the like of a leaching solution, and compare the pollution indexes with the requirements of the pollution control standard GB18599-2001 of common industrial solid waste storage and disposal sites to preliminarily determine the pollution degree; carrying out formula design or carrying out multiple screening and optimization on curing treatment agents according to the past curing experience and a conventional formula, carrying out a curing experiment for 5-7 days, detecting a cured sample, and detecting whether the standard requirement of GB18599-2001 is met; and if the sample pollution index after the curing formula treatment does not meet the requirement, optimizing and modifying the formula again, performing the sample curing experiment again for 5-7 days, and performing leachate index test to repeatedly prove the effect of the formula. The tests are repeated for a plurality of times until the curing formula ensures that the waste residue after curing treatment meets the I/II requirements of the pollution control standard of the general industrial solid waste storage disposal site GB 18599-2001.
The conventional test method has the following problems: firstly, the test cost is high, and because multiple tests are carried out and various indexes of the leachate are required to be tested after each test, high tests and test cost are generated; secondly, the test efficiency is low, the time consumption is long, according to the regulation of the standard GB18599-2001, the solidification treatment of the drilling solid waste residue and various pollution indexes of the leaching solution need more than one week, the test period of each round is too long, and the test progress is greatly reduced.
