Description
Technical Field
The invention relates to an oil pipe used in the field of oil extraction in oil fields, in particular to a wax-proof anticorrosive pipe for oil and gas fields.
Background
With the rapid development of the industrial exploration and development of petroleum and natural gas in various countries, oil and gas fields containing various corrosive media such as high H2S, CO2, chloride ions, hydrates and the like appear in succession, so that the problems of safety, corrosion, wax deposition, scaling and the like of the working environment of the petroleum pipe are more prominent. The crude oil in China is rich in wax, the wax content of most of the crude oil is higher, the wax content of most of the extracted crude oil is over 20 percent, some crude oil is even as high as 40 to 50 percent, and the crude oil with the wax content of over 10 percent accounts for 90 percent of the whole produced crude oil. In the western crude oil of China, such as Tuhaa, Tasouthwest and flame mountain, the paraffin between C36-C70 accounts for almost 50% of the whole wax content. FIG. 1 shows the statistical data of wax content of crude oil, and it can be seen from FIG. 1 that most of the crude oil in China has relatively high wax content, and the permeability of the oil layer is reduced due to the high wax content of the crude oil. In oil and gas exploitation, wax is separated and precipitated from oil, and continuous wax precipitation causes blockage of an oil production layer, reduction of oil well yield and even production stoppage, and brings troubles to production.

The following examples further illustrate embodiments of the present invention. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
In the process of oilfield flooding and crude oil transportation, due to the changes of environmental conditions such as pressure, temperature and the like and the adsorption effect of a fluid medium and the surface of a pipe, wax and inorganic salt in the transportation medium can be deposited on the pipe wall to form a wax scaling layer, so that the flow area of a pipeline is reduced, and the transportation resistance is increased. In principle, the surface energy of the material is an important factor for inducing wax precipitation and scaling. Therefore, the purposes of wax and scale prevention can be achieved by selecting a material with low surface energy or reducing the surface energy of the material through surface modification. Organic coatings have been widely used on the inner wall of pipes, and because of their low polarity and low surface roughness, the coatings also have significant anti-waxing and anti-scaling properties.
Influence of surface free energy on wax deposition, scaling:
generally, objects on earth are in an environment of air (including vapors of certain substances), and the surface tension of liquids is usually measured in both liquid and vapor (air) environments. For this reason, the measured value is actually the liquid/gas interfacial tension. But the value is very close to the surface tension of the liquid measured in vacuum.
Wetting is a common phenomenon in nature and in production processes, and the process in which the solid-gas interface is replaced by a solid-liquid interface is called wetting. After the liquid and the solid are contacted, the free energy of the system is reduced, and the wetting degree of the liquid on the solid can be measured by the reduction of the free energy of the system.
FIG. 2 shows the relationship between contact angle and interfacial energy, FIG. 3 shows the wetting condition by contact angle, theta is called contact angle, i.e. the included angle of tangent of solid-liquid surface at the three-phase contact point. The value of θ may be from 0 to 180 °.
(1) When theta is 0 degrees, the liquid completely wets the solid surface or ideally wets, and then the liquid is dispersed on the solid surface to become a monomolecular film theoretically;
(2) when theta is more than 0 and less than or equal to 90 degrees, the liquid part wets the solid, and the larger theta is, the smaller S is, and the larger the water-repellent and oil-repellent capacity of the solid is;
(3) when the angle is more than 90 and less than 180 degrees, the liquid does not wet the solid. If the liquid is water, the solid has the function of water repellency, and if the liquid is oil, the solid has the function of oil repellency;
(4) when θ is 180 °, incomplete wetting is referred to. From this, it is found that the smaller the contact angle θ, the better the wetting, and conversely, the worse the wetting.
Researches find that the polymer coating of the nano titanium and the tantalum has excellent wax-proof and corrosion-proof performances. The anticorrosive paint is prepared by utilizing the mechanochemical reaction principle to carry out molecular intercalation grafting technology on functional nano-scale materials. The anticorrosive coating processed by the anticorrosive coating has very low surface free energy and very strong double-phobicity (oleophobic and hydrophobic), and can not form a relatively stable water film and oil film on the inner wall of a pipe, so that the wax is not easy to precipitate. Besides the excellent wax-proofing function, the polymer coating of the nano titanium and the tantalum also has the unique properties of excellent acid-base corrosion resistance, high adhesive force, wear resistance and the like, can well protect the normal operation of oil (sleeve) in an oil-gas well, and saves a large amount of unnecessary cost for the oil-gas field; the modified epoxy phenolic coating can form Fe-O bonds with iron in an iron pipe through epoxy groups in epoxy resin, so that a coating is tightly attached to the surface of the inner wall of an oil (sleeve) pipe, high polymers in the coating are cured at high temperature to form a compact net-shaped structure, the surface of the coating is flat and glossy, the coating is hard, the surface friction coefficient is low, the surface energy is low, and the coating has antifouling retention property and extremely strong amphiphobicity (oleophobic property and hydrophobic property), so that various scales and waxes are difficult to attach to the coating. Besides, the coating also has the corrosion resistance to CO2 and a small amount of H2S, Cl-, hydrochloric acid, earth acid and sodium hydroxide.
