Abstract
The invention discloses a water-based flash point-free wax cleaning agent and a preparation method thereof. The wax cleaning agent consists of the following raw materials in percentage by weight: 20 to 40 percent of surfactant and 60 to 80 percent of deionized water. The preparation process is simple; and the wax cleaning agent is convenient to use, high in safety and low in manufacturing cost, meets the environment-friendly Restriction of Hazardous Substances (ROHS) standard, has good application prospect, and does not have flash points.
Description
Technical field
The present invention relates to the clean-out system technical field, particularly relate to a kind of aq. type without flash-point parent cerate and preparation method thereof.
Background technology
When developed in the oil field, crude oil flowed into the shaft bottom from oil bearing reservoir, again from the shaft bottom along wellbore lift to wellhead pressure, temperature descends thereupon.When pressure decreased to a certain extent the time, destroy paraffin and be dissolved in equilibrium conditions in the crude oil, cause wax crystal to be separated out.During the temperature that the drop in temperature of crude oil begins to separate out to the wax crystalline substance (wax precipitation piont), the brilliant particulate of wax just begins to separate out at oil stream and tube wall.Along with the further reduction of temperature, pressure, paraffin will constantly be separated out, and its xln is just assembled and is deposited on the tubing such as oil pipe, sleeve pipe, sucker rod, oil well pump and the equipment.When wax deposition is serious, can stop up oil pipeline fully, cause stopping production.Therefore, when oil-field development, often use the wax clean-out system, still, contain aromatic hydrocarbons in traditional wax clean-out system, such as benzene, toluene and dimethylbenzene etc., this type of raw material has flash-point, and flash-point is lower, and the danger of catching fire is arranged in the high speed operation process, and security is low.
Summary of the invention
Based on this, be necessary the problem for the shortcoming of prior art, provide a kind of aq. type without flash-point parent cerate and preparation method thereof, this parent's cerate is without flash-point, and security is good, and preparation technology is simple, and cost of manufacture is low, and is easy to use.
A kind of aq. type is without flash-point parent cerate and preparation method thereof, and described close cerate is comprised of the raw material of following weight per-cent:
Tensio-active agent 20 ~ 40%;
Deionized water 60 ~ 80%;
The percentage ratio sum of above each component content is 100%.
Among embodiment, described tensio-active agent is the alkylamide ethoxy compound therein.
Among embodiment, described preparation method may further comprise the steps therein:
1., get the raw materials ready: described tensio-active agent and deionized water are weighed according to described weight percent, with for subsequent use;
2., mix: tensio-active agent and deionized water that step is weighed in 1. mix in mixing vessel;
3., stir: begin to mix tensio-active agent and deionized water in the container, tensio-active agent and deionized water are fully mixed, namely obtain described close cerate.
Above-mentioned aq. type is without flash-point parent cerate and preparation method thereof, and this parent's cerate is aq. type, and without flash-point, security is good, and is easy to use, and its preparation technology is simple, and cost of manufacture is low.It can be prepared at normal temperatures, adds this parent's cerate in crude oil, has just changed the wax-crystal structure in the crude oil, makes the wax crystalline substance be in dispersion state, and not mutually stack is suspended in the crude oil each other.In addition, the present invention meets environmental protection ROHS standard, has a good application prospect.
Embodiment
A kind of aq. type is without flash-point parent cerate and preparation method thereof, and described close cerate is comprised of the raw material of following weight per-cent:
