Abstract

The invention relates to an oilfield oil sludge cleaning agent. A problem that a conventional oilfield oil sludge cleaning agent is low in oil scrubbing rate and incomplete in cleaning is mainly solved. The oilfield oil sludge cleaning agent is characterized by comprising the following components in percentage by weight: 2-8% of an emulsifier, 1-5% of a washing assistant, 6-15% of sodium dodecyl benzene sulfonate, 1-8% of dodecyl trimethyl ammonium chloride, 2-6% of a thickening agent, 1-5% of a chelating agent and the balance of water. The preparation method comprises the following steps: adding the water, the emulsifier, the sodium dodecyl benzene sulfonate, the dodecyl trimethyl ammonium chloride, the thickening agent, the washing assistant and the chelating agent into a reaction container, and stirring until the materials are completely dissolved, so as to obtain the oilfield oil sludge cleaning agent. The oilfield oil sludge cleaning agent has the oil scrubbing rate of 95% or higher, has excellent dispersing and solubilizing effects and does not pollute the environment.

Description

technical field [0001] The invention relates to an auxiliary agent in the field of oilfield development chemical treatment agents, in particular to an oilfield sludge cleaning agent and a preparation method thereof. Background technique [0002] At present, domestic researches on the treatment of oilfield ground oil and aged oil are very concerned, and some research work has also been carried out, but it is still mainly in the stage of industrial experimentation and has not been realized in large-scale application. Analyzing the reasons, in addition to the complex nature of the oilfield produced fluid, which is difficult to control, the serious environmental pollution of sludge has become one of the most important obstacles. [0003] There are usually two methods of cleaning sludge and aging oil, physical cleaning and chemical cleaning. It is impossible to solve the problem of sludge pollution by purely physical methods, and chemical cleaning agents must be used for cleanin...
