Specifications for processing oil pipe short joints

Oil pipe short-circuit refers to oil pipes shorter than R1. Its length is usually 0.3 meters to 6 meters. And the 1FT-20FT commonly used abroad. The basic specifications, steel grade, and usage environment are the same as those of ordinary oil pipes. The pipe body implements the ninth edition of API Spec-5CT. Thread processing follows API Spec-5B-2008. Types are divided into: short circuits are commonly divided into ordinary short circuits, double male short circuits, and overall thickened short circuits.

Oil pipe short joints are short oil pipes. They are mainly used for oil, natural gas, shale gas/shale, oil pipe wear-resistant short joints, direct-connect large-head oil pipe pup joints, coal bed methane, hot springs, oil pipe pup joints | joint processing specifications, geothermal mining .

① Extracting oil and gas: After the gas well is drilled and cemented, oil pipes/short connections are placed in the oil layer casing to extract oil and gas to the surface.

② Water injection: When the downhole pressure is not enough, inject water into the well through the oil pipe/short-circuit.

③ Steam injection: During the thermal recovery process of heavy oil, insulated oil pipes/short-circuits must be used to input steam downhole.

④ Acidification and fracturing: In the later stages of well drilling or in order to increase the production of oil and gas wells, it is necessary to input acidification and fracturing media or solidified materials to the oil and gas layers. Oil pipe nipples, media and solidified materials are all transported through oil pipe short joints.
