Detail Information
1. The classification of petroleum tubing.
Petroleum tubing is divided into flat tubing (NU), thick tubing (EU), and integral joint tubing (IJ). The flat tubing refers to the pipe end which is directly threaded without a thickening and with a coupling. Thickened tubing means that after both ends are thickened, they are threaded and coupled with a coupling. Integral joint tubing means that one end passes the internal thickened car external thread and the other end passes the external thickened car internal thread, and is directly connected without a coupling.
2. The role of petroleum tubing.
① Extraction of oil and gas: After the oil and gas well is drilled and cemented, an oil pipe is placed in the casing of the oil layer 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.
③ Steam injection: In the process of thermal recovery of heavy oil, it is necessary to input steam to the downhole with insulated tubing.
④ Acidification and fracturing: In order to increase the production of oil and gas wells in the later stage of well drilling, it is necessary to input the acidification and fracturing medium or solid matter to the oil and gas layer. The medium or solidified matter is transported through the tubing.
