Tubing shorting refers to tubing shorter than R1 length. Its length usually ranges from 0.3 meters to 6 meters. And foreign habits of 1FT-20FT, etc. The basic specifications, steel grade, and use environment are the same as ordinary tubing. The tube performs API Spec-5CT Version 9. Threading is performed by API Spec-5B-2008. Types are divided into: short common is divided into ordinary short, double short, overall thickened short.
Tubing shorting is short tubing, mainly used in oil, natural gas, shale gas/shale, tubing wear-resistant shorting, direct link big head tubing nipple, coal bed methane, hot spring, tubing nipple | connection processing specifications, geothermal exploitation.
Extraction of oil vapor: After the gas well is completed and cemented, a tubing/short connector is placed in the oil layer casing to extract oil and gas to the surface.
② Water injection: When the downhole pressure is not enough, water is injected into the well through the tubing/short connector.
③ Steam injection: In the process of heavy oil thermal recovery, steam should be input to the well with insulated tubing/short connection.
(4) Acidizing and fracturing: in the later stage of drilling or in order to improve the production of oil and gas Wells, it is necessary to input acidizing and fracturing media or solidifying substances into the oil and gas reservoir, and the oil pipe joints, media and solidifying substances are transported through the oil pipe short connection
