Strengthening and Heat Treatment Process of Oil Screen

The oil screen is a large diameter pipe that acts as a fixed oil and gas well wall or wellbore. The casing is pierced into the wellbore and fixed with cement to avoid the collapse of the borehole and the borehole and to ensure that the drilling mud circulates in order to facilitate drilling and digging. The different types of bushings used in the oil excavation process: The surface oil sieve tubes maintain drilling to avoid contamination by the shallow and shallow layers, supporting the wellhead equipment and holding the other layers of the casing. Skills The oil sieves are separated from the same level of pressure so that the amount of drilling fluid normally flows and maintains the production casing. In order to reverse the equipment in the drilling equipment, leak-proof equipment and tail pipe. Oil reservoirs export oil and natural gas from the storage layer under the surface. Used to maintain drilling, stratify drilling mud. Oil sieve production, the outer diameter is generally 114.3 mm to 508 mm.
Domestic economic data show that the economy is still down. The second is the domestic labor, capital, financing and other costs and the need to weaken the manufacturing industry will be affected; third is the production of raw materials and other companies continue to be in the inventory during the period, And even show limited prices such as price insurance. Fourth, the real estate industry in the face of the volume and price of the depth of adjustment, will make steel, building materials and home appliances and other related industries affected. In the country always need to slow down the layout, the second quarter of economic growth is expected to continue to slow down the trend.
