Materials of petroleum casing and common problems in its application

Oil prices have been rising over the past few years, and as prices rise, so do the costs of drilling and extracting oil. To reduce costs, many oil companies use plastic pipes instead of metal pipes in oil wells. While this may be cheaper in the short term, it may cause problems in the long term. The role of oil casing: Oil casing is a special kind of pipeline, mainly used for transporting and storing oil products. It has the characteristics of corrosion resistance, high temperature resistance and high compressive strength. Oil casing is usually made of stainless steel, nickel steel, aluminum alloy and other alloys. The main functions of petroleum casing include transporting crude oil, natural gas, petroleum products and chemical products; storing liquid chemical raw materials and finished products; transporting fluids and gases for oil and chemical products; transporting high-temperature liquids and gases.

Material of oil casing: Oil casing is a jacket used to wrap and protect oil pipelines. There are many materials for oil casing, and different materials need to be selected according to different usage requirements. Common petroleum casing materials include nickel steel casing, stainless steel casing, galvanized casing, aluminum casing, tinned casing, galvanized zinc steel casing, fiberglass casing, etc. Construction methods: The construction methods of oil casing are mainly divided into two types: drilling and blasting. Drilling is to drill a hole in the ground connected to a well with the help of an underground drilling machine. Blasting is to place explosives at the bottom of the well and control the time and intensity of the explosion so that the shock wave generated by the explosion passes through the well. wall and destroy the well wall to form a pothole.

Frequently Asked Questions: 1. Under what circumstances is it necessary to use oil casing? 2. What are the advantages of oil casing? 3. What are the installation methods for oil casing? 4. What are the precautions for using oil casing? Using plastic pipes can cause many problems for oil companies. First, it is not as durable as metal pipes and is more susceptible to damage. It is also less resistant to heat, which can cause problems with oil well equipment. Additionally, plastic pipes release harmful chemicals into the environment. All of these factors end up costing oil companies more money in the long run.
