Petroleum casing emerged not only for oil extraction but also as a pipeline for transporting raw materials. In order to strengthen the quality of petroleum casing, every link in the production process is particularly important, especially the temperature control during the period, which must be mastered in strict accordance with the regulations. Usually, the petroleum […]
La tubería de revestimiento es un tubo de acero que se utiliza para sostener la pared de los pozos de petróleo y gas con el fin de garantizar el proceso de perforación y el correcto funcionamiento de todo el pozo una vez terminado. En cada pozo se utilizan varias capas de tubería de revestimiento en función de la profundidad de perforación y las condiciones geológicas. La tubería de revestimiento se [...]
Different types of casing used in the oil recovery process: surface oil casing – protects the drilling well from contamination by shallow water and gas formations, – supports the wellhead equipment and maintains the weight of other layers of the casing. Technical casing – separates the pressure in the different layers to allow proper flow […]
Oil casing is an important equipment for oil drilling, and its main equipment includes drill pipe, core pipe and casing, drill collar and small diameter steel pipe for drilling. The domestic casing is made of geological drilling steel by hot rolling or cold drawing, and the steel number is “geological” (DZ), and the common casing […]
Oil casing is a steel pipe used to support the well wall of oil and gas wells to ensure that the drilling process is carried out and that the entire well operates normally after completion. Several layers of casing are used in each well according to different drilling depths and geological conditions. The casing is […]
Oil casing is the lifeline to maintain the operation of oil wells. Due to different geological conditions, the state of downhole stress is complex, and the combined effects of tensile, compressive, bending and torsional stresses act as Zhixin Group for the pipe body, which puts high demands on the quality of the casing itself. Once […]
When the well is drilled to the destination layer (oil and gas-bearing layer), the oil layer casing is needed to seal the oil and gas layer and the upper exposed strata, and the oil layer is inside the casing. The oil layer casing is the deepest among all types of casing, and its mechanical properties […]
Oil and gas wells are fixed assets of an oil and gas company, and the formation casing is the most basic element of an oil and gas well. Once the oil formation casing is damaged and cannot be repaired, it means the scrapping of the oil and gas well and the loss of fixed assets. […]
In the working process of the screw pump, the rotor rotation will trigger the twisting and vibration of the oil pipe. In addition, the J-groove of the tubing junction is subject to high friction during the extraction process, which is where most of the tubing damage and deterioration problems occur. At the same time, operators […]
El revestimiento de petróleo es un tubo de gran diámetro que sirve para asegurar la pared o la perforación de los pozos de petróleo y gas. La tubería de revestimiento se introduce en el pozo y se fija con cemento para evitar que el pozo se separe de la formación rocosa y se derrumbe, y para garantizar la circulación del lodo de perforación a fin de facilitar la perforación y la extracción.Acero [...]
