An oilfield solid waste treatment agent and resource treatment process

Abstract

The invention discloses an oilfield solid waste treatment medicament. The oilfield solid waste treatment medicament is characterized by comprising the following components of, a pour point depressant,a pH regulator, a dispersing agent, a viscosity reducer, a cleaning agent A, a cleaning agent B, a dehydrating agent, a photocatalyst, a zeolite molecular sieve, activated carbon, a ceramic ring, ananti-adhesive agent and a desulfurizing agent. The oilfield solid waste treatment method comprises the following steps of performing thermal chemical washing operation and dry distillation carbonization operation, according to the characteristics of oilfield solid waste generated by different stratums or working conditions, the thermal chemical washing operation or the dry distillation carbonization operation is independently adopted, or the thermal chemical washing operation is carried out firstly, and then the carbonization operation is carried out. The oilfield solid waste recycling treatment process is simple and feasible, and the application range is wide; the treated solid phase, oil, water and gas can be recycled, and the standard solid phase is used as a civil engineering raw material; the oil phase is recycled to an oilfield or used as an industrial oil raw material; the water phase is recycled to a cooling device or can be used in the thermochemical cleaning operation; and the non-condensable gas enters a combustion chamber of a dry distillation furnace for combustion and heat supply, so that the environment-friendly requirement is met.

Description

technical field [0001] The invention relates to the technical field of oily waste treatment produced in drilling engineering in the field of oil and gas field exploitation, in particular to an oilfield solid waste treatment agent and a resource treatment process. Background technique [0002] As an unconventional energy source, shale gas can greatly relieve the pressure on energy supply due to its advantages of abundant reserves, long mining life and long production cycle. However, due to the high water sensitivity of shale gas reservoirs, it is difficult for conventional water-based mud to drill smoothly, and the mining is difficult, and the requirements for mud performance are very high. Oil-based mud has the advantages of good lubricity, strong inhibition, good thermal stability, wide range of density, easy adjustment of rheology, resistance to various salt pollution, and strong inhibition of mud shale; and because The filtrate is the oil phase, which avoids the water se...

AI Technical Summary

Problems solved by technology

The incineration method is burned in proportion to the fuel, which will produce secondary pollution

The chemical cleaning method uses emulsifiers to break the emulsion and recover the oil phase, which consumes a lot of water, and the resulting oil-water mixture causes secondary pollution

When the microbial metabolic degradation method is used, it is not conducive to oil recovery. At the same time, the aromatics contained in the oil are relatively high, which can inhibit microbial metabolism, resulting in a long decomposition cycle.
