Abstract
The invention discloses a ten-meter long silicate compound oil casing pipe and a manufacturing method. The oil casing pipe manufactured based on the API standard mechanism abided by the international petroleum industry serves as a base material. The oil casing pipe is composed of a pipe body and a coupling, wherein the two ends of the pipe body are provided with a hand-tight thread and a basic machine tight thread respectively, and the coupling is connected with the basic machine tight thread. The surface of the inner wall of the pipe body is coated with a silicate coating, the silicate coating and the base material are sintered and combined into a whole, and the overall length of the oil casing pipe is ten meters. The manufacturing method comprises the steps of grinding the silicate coating purchased from the market in a mixed mode, processing the surface of the pipe body, carrying out screw thread protection, coating the silicate coating, drying at the low temperature, sintering and cooling. The oil pipe and the casting pipe are long in service cycle, good in scaling performance, wax precipitation performance, temperature resistance performance and cold resistance performance, and capable of being widely popularized and used.
Description
Technical field
The present invention relates to oil-gas mining technical field, relate to a kind of silicate compound oil casing pipes and manufacture method of 10 meters long corrosion-resistant, resistive connection waxes.
Background technology
Along with deepening continuously of oil field development, the exploitation of a lot of oil gas fields of China has entered into the middle and later periods, in order to improve produced quantity, the oil production technology of Various Complex adopts successively, cause crude oil Produced Liquid complicated components, corrosivity increases, and fouling wax deposition situation is serious, and even a lot of oil pipes are gone into the well penetration phenomenon has just been occurred half a year.The anticorrosion means of existing oil well pipe, sleeve pipe adopt organic coating more, and the situation that can slow down to a certain extent anticorrosion, fouling, wax deposition occurs.But organic material is owing to being subject to the restriction of its hardness, temperature tolerance and aging, final anticorrosion produce effects unsatisfactory.
At present, tubing and casing is all in the U.S. API standard that adopts whole world petroleum industry jointly to follow, and standard tubing and casing is for being threaded, and length of oil sleeve pipe is more than 9 meters, straightness accuracy≤1/1000.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of 10 meters long silicate compound oil casing pipes and manufacture method are provided, and to solve, existing oil pipe and sleeve pipe life cycle are short, fouling wax deposition, the poor problem of heatproof winter resistance.
The technical scheme adopting is:
A kind of 10 meters long silicate compound oil casing pipes, the tubing and casing of the U.S. API standard mechanism that employing international petroleum industry is followed is jointly base material, described tubing and casing is respectively equipped with hand-tight screw thread and the body of the basic tight screw thread of machine and the box cupling being tightly threaded with basic machine by two ends, described inboard wall of tube body surface spraying silicate coating, silicate coating and base material are complex as a whole through burning till, and product entire length reaches 10 meters.
The manufacture method of silicate compound oil casing pipes, comprise mix grinding, body surfacing, screw thread protection, the silicate paint of silicate paint (commercial product) spraying, low temperature drying, burn till and cooling step.
The mix grinding of a, silicate paint: the clear water mix grinding that with ball mill, silicate paint is added to setting;
B, body surfacing: adopt heating in medium frequency mode to body inside and outside wall and pipe collar, screw thread oil removing degreasing, inboard wall of tube body is processed to reach through sandblast (ball) and sprayed or Sa2.5 level or the manual St2.5 level requirement of closing powertool cleaning of centrifugal blast cleaning;
C, screw thread protection: carry out conservation treatment at pipe collar and screw thread end, put special thread protector;
The spraying of d, silicate paint: adopt airless sprayer that inorganic silicate coating is sprayed onto to inboard wall of tube body, oscillating uniform device is controlled the surface quality that body waves, rotates to adjust inwall silicate paint automatically;
E, low temperature drying: body is suspended on walking line, utilizes the remaining temperature of firing furnace to carry out low temperature drying 1 ~ 3 hour;
F, burn till: body enters in natural gas firing furnace, after 800 ℃ ~ 900 ℃ high temperature burn till 5 ~ 20 minutes, comes out of the stove;
G, cooling: naturally cooling under room temperature.
Oil pipe of the present invention and sleeve pipe life cycle length, fouling, wax deposition, heatproof, cold performance are good, can promote the use of widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
