On April 13, the test procedure of selecting test valve was successful in high temperature and high pressure reservoir oil test of No.3-27 Nanpu Oilfield in Jidong Oilfield, which greatly expanded the scope of application of test valve. The depth of the test wells in Nanpu 3-27 well is above 4,400 meters and the formation pressure coefficient is 1.4. Deep wells, high formation pressure coefficient, difficult to test, and the measured reservoir temperature of 164 degrees Celsius also created a choice of test valve in the domestic application of temperature records. Jidong Oilfield Exploration and Development Project Department and Bo drilling test company technical staff through systematic verification, creatively change the selection of test valve pressure collection and relief part of the structure of the key components of the repeated maintenance commissioning, selection of high temperature seals, optimize the design of the column Structure, and pre-test simulation of different conditions in the workshop operation. In the field application, the workers from the wellbore preparation, the test oil into the well tool, perforating perforation, test the switch well and other links step by step, fine operation, and ultimately ensure that the well of two high temperature and high pressure test success, Obtained formation liquidity and productivity parameters. The choice of test valve has withstood the test of harsh conditions such as high temperature and high negative pressure, adding technical means for oil testing of special reservoirs, marking the improvement of the special oil testing technology of Jidong Oilfield.
Welding Rope
Tungsten carbide welding rope is a type of welding filler material that is used for hardfacing applications. It is made by combining tungsten carbide particles with a binding material, such as nickel or cobalt, to create a rope-like form.
Tungsten carbide is known for its exceptional hardness and wear resistance, making it ideal for applications where the welded surface needs to withstand extreme abrasion and impact. The welding rope is typically used in industries such as mining, oil and gas, construction, and agriculture.
When the tungsten carbide welding rope is heated during the welding process, the binding material melts and fuses the tungsten carbide particles to the base metal, creating a hard and durable surface. This helps to extend the lifespan of equipment and machinery by protecting it from wear and tear.
Tungsten carbide welding rope can be applied using various welding processes, including manual metal arc welding (MMA), gas tungsten arc welding (GTAW), and flux-cored arc welding (FCAW). The choice of welding process depends on the specific application and the equipment available.
Overall, tungsten carbide welding rope offers a cost-effective solution for protecting and repairing high-wear surfaces, making it a popular choice in industries where durability and longevity are essential.
