Information exchange Two new materials for drill pipe coating For decades, the drilling industry has been seeking a complete new material for pipe coating, because the rough inner wall of the pipe has an adverse frictional effect on the drilling fluid pumping. The pump flow can be increased, and the pump pressure can be controlled. According to 06 Xiankan also milk, 1 reported. American company developed a kind of 1 button coating powder. This material can withstand high temperature and acidic solution and can also prevent wire rope damage and corrosion, 330124 00 coating powder. There is no leakage coating phenomenon. The process is to perform hot cleaning of 121 on the tube at 399, high temperature, and then apply primer in the tube. Heat the tube again. Spray the powder. After the powder is melted, the tube is hardened by a transfer furnace, and the drill pipe that passes through the inner coating can withstand the high temperature of 17712, because the friction coefficient of the powder material is low. The drilling fluid flow is greater. If the flow rate is increased by 15, the size of the drilling pump can be reduced and the quality of the rig can be reduced. The wet rub hardness test of the corrosion of the wire rope shows that the performance of the 1-button 100-coated powder is more than 4 times better than that of the coating-only film. Furthermore, it was tested against organic and inorganic acids that the powder coating was much more durable than the conventional coating used in the comparative test. Such as in the highly corroded underground environment in the northwest of Luzhou, USA. Drill rods coated with 1 button 100 powder coating can last for years, while drill pipes that have been coated with ordinary coatings are only damaged after 56 weeks of downhole. The American company III, 18 developed a different coating material. The product name is! . The coating material contains ceramics, such as by mass, which are incorporated into an epoxy binder resin to form a ceramic epoxy composite which is initially liquid on the drill pipe. After hardening and chemical cross-linking treatment, the inner wall surface of the drill pipe is hard and can withstand impact and abrasion. Its mechanical initiality can extend the life of the drill pipe by a factor of about a second. This coating material is used in addition to grades 08, and 016, outside the drill pipe. It can also be used for watertight pipes up to 27,1. Hu Xinhe Norwegian River Company top drive developed new dynamic top drive and PCT series heavy top drive. In the series of top drive, the original sweat was removed, and the 1350 model was driven. It has formed a new series top drive with three specifications, including 1 counter, 0, 1410 and 15甩. Tish load 3, input power 5807 wash evaluation. In the 00 PCT series top drive, the 00 elbow 500 top drive was cancelled, and the increase of nearly 1 was developed. The 1 stick 650 type formed 1 his S.DDM650HY750 kind of 00 new series top drive. Sweat-carrying 1; 65,075 Guanfan 迕 pure twist in the above two series of products, 103350 type 410 PT.n500 top drive are hydraulically driven. The other three types of top drive adopt 9 electric drive type, and the winter drill can reduce the casing wear. The drill pipe joint surface alloy coating professional alloy company jointly developed an alloy coating applied to the drill pipe joint surface to reduce casing wear. . This new coating material, called the 3100 outer alloy, is a low-carbon iron-based alloy containing a small amount of chromium, which is characterized by low cost and simple coating process. In order to test the performance of this new coating material, the company used a drill pipe joint sample to carry out a simulation comparison test under the same drilling conditions and the same lateral load conditions. The test results show that the alloy coating is applied. The drill pipe joint can significantly reduce the wear on the casing, and the drill pipe joint itself has not found any stress cracks. Its performance is significantly better than the steel drill pipe joint without the alloy coating and the drill pipe joint with the spherical tungsten carbide hard layer. Tested. The radial wear of the drill pipe joints, which are coated with the alloy coating and the uncoated alloy coating, are respectively 01651 before 1 and 51, the former being 3.25 times of the latter, and the drill with spherical tungsten carbide plus hard layer. The radial wear of the rod joint is zero; the friction of the 0.4 joint of the alloy coating 14 is 1.45 for the bamboo sleeve, and the drilled joint without the alloy coating and the spherical tungsten carbide plus hard layer dry running seal Technology with the development of dry running non-contact air seals and the application of spiral groove sealing technology. The sealing reliability of the centrifugal compressor has been improved, and a large amount of lubricating oil is no longer used. And the average time between repairs is greatly extended. However, the existing sealing arrangement is relatively simple. This single seal is limited to inert or non-toxic treatment nights. The service pressure is only 280 阽 3. Surgery can solve many complex questions. The two existing sealing products are Type 281 tandem double seals, which can be used to seal dangerous or toxic gases. The space between the M seals can pass gas to the steam treatment system or the flare system. This tandem seal is divided into two parts. That is, the inside and the outside, when the inner seal fails, the evening seal can be used as a safety seal to prevent leakage. Its service pressure is 5.4 cubits, if higher operating pressure is required. It is necessary to solve the problem of 0 shape, blasting pressure relief secondary sealing friction and sealing surface deflection. To this end, the company has developed another product, the 28-type tandem double seal, which is a spring-activated polymer seal that is not easily blasted. There is a support sealing mechanism inside. The sealing surface can be controlled to be skewed. Its service pressure 21. In order to adapt to the reverse rotation of the compressor, a two-way sealing surface groove is designed. The original one-way spiral groove profile still maintains the best sealing performance. In addition, the company has developed a tandem seal that can be used in refinery hydrogen recirculation compressors, saving users $170,000 annually. Nanben column editor Xie Shouping
