What are the types of oil pipelines?
Generally speaking, there are two types of oil pipelines: carbon steel pipes and oil-resistant rubber hoses. Many of the fixed oil pipelines we see now mostly use carbon steel pipes, while oil-resistant steel pipes play an important role in the temporary loading and unloading of active parts of oil transportation facilities. In carbon steel pipes, it can also be divided into seamless steel pipes and welded steel pipes according to different manufacturing methods, and seamless steel pipes are also divided into hot rolled and cold drawn.
What are the safety measures for oil pipelines?
Oil pipeline is an important part of modern energy transmission, it carries a large amount of oil and natural gas resources, so safety issues are particularly important. In order to ensure the safe operation of petroleum oil pipelines, a series of strict safety measures need to be taken. This article will introduce some common oil pipeline safety measures.
Oil pipelines require frequent inspections and maintenance to detect and deal with potential problems. Leak detection is the key link. By using high-precision leak detection technologies, such as gas detection, liquid flow meters and smart sensors, pipeline leaks can be detected and located early. In addition, using remote sensing technology and drones and other modern technical means, it is possible to conduct a comprehensive inspection of the pipeline, find out the abnormal condition of the pipeline in time, and take corresponding maintenance measures.
To sum up, oil pipeline safety measures cover many aspects, including engineering design, monitoring and maintenance, anti-corrosion and heat preservation, emergency response, regulatory compliance, environmental protection, information technology application, and international cooperation. By taking these measures comprehensively and effectively, the safe operation of oil pipelines can be ensured to the greatest extent and reliable support for energy supply can be provided.
What is the difference between oil tubing and casing pipe? Where is the oil well separately? Is the casing pipe the one that is the outermost layer of the well? Let me help you answer the following:
Tubing and casing pipe are essential tools for oil exploration.
The tubing is a tube that is lowered into the casing of the well when the well is being produced normally. From the well, the oil flows through the oil pipe into the ground and enters the gathering process. In the coal mining well, the combination of oil pipe, sucker rod and deep well pump draws oil to the ground and enters the gathering process.
The casing is a pipe that is lowered into the well after the drilling is completed. The casing and the well wall are cement-sealed, and then the perforating gun is used to align the perforation of the target layer, so that the oil flows through the rock layer, the cement ring, and the casing into the well. At the bottom, enter the tubing and come to the ground. The main role is:
1. Reinforce the well wall to prevent the formation from collapsing;
2. Separate different oil layers and water layers to achieve stratified mining;
3. Easy to implement fracturing, acidification and other measures and maintenance operations;
4. The formation of oil flow channels, with the oil pipe to achieve the purpose of oil recovery.
The order is: after the oil well is laid, the casing is placed, the casing and the well wall are sealed with cement, and the oil pipe is placed in the casing. The oil pipe is equipped with a downhole tool such as an oil packer and a pump. The sucker rod is inserted into the oil pipe, and the sucker rod pulls the piston of the pump to reciprocate up and down. In this way, the oil is pumped to the ground.
