In the overlapping area of coal and oil and gas resources, due to the deeper oil deposits, the oil wells penetrate the coal strata, and the secon-hand oil well casing acts on the deformation and damage of the working site, changing the original mechanical state of the roof. At present, the phenomenon of toxic and […]
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 […]
오일 케이싱은 석유 및 가스 유정의 유정 벽을 지지하여 시추 과정을 수행하고 완료 후 전체 유정이 제대로 작동하도록 하는 데 사용되는 강관입니다. 시추 깊이와 지질 조건에 따라 각 유정에는 여러 층의 케이싱이 사용됩니다. 케이싱은 [...]입니다.
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 […]
석유 및 가스 유정은 석유 및 가스 회사의 고정 자산이며, 지층 케이싱은 석유 및 가스 유정의 가장 기본적인 요소입니다. 유정 케이싱이 손상되어 수리할 수 없게 되면 유정의 폐기와 고정 자산의 손실을 의미합니다. [...]
스크류 펌프의 작동 과정에서 로터 회전은 오일 파이프의 비틀림과 진동을 유발합니다. 또한 튜브 접합부의 J 홈은 추출 과정에서 높은 마찰을 받기 때문에 대부분의 튜브 손상 및 열화 문제가 발생합니다. 동시에 작업자는 [...] [...]
