oil-water sludgewell pipe

 

At present, and also according to user requirements developed with independent intellectual property rights of the series of casing, such as tianjin steel tube company developed a TP series the collapse resistance of casing, casing corrosion resistance, resistance to high temperature thermal recovery Wells with casing, ultra deep well with button and special gas tightness casing pipe, including TPl30TT high collapse casing its collapsing strength reached more than 167 mpa.TPll0TSS high extrusion resistance corrosion resistance casing in sodium chloride 5%, acetic acid 0.5% oxidizing corrosion solution, 720 hours without fracture;The TP140V runs to a depth of 6,936 meters (a record that will be broken soon).NC 1 3Cr carbon dioxide corrosion resistant casing has been sent to tarim oilfield for downhole use.In addition, baosteel and chengdu seamless have developed their own series of products.Although Chinese seamless steel tube industry in the oil well pipe has made remarkable achievements, but in some high-end product development there is no pass, such as 13 cr, super 13 cr steel inclusion and control the content of S and P (S less than 10 PPM, P is less than 15 parts per million (PPM), the performance of the heat treatment control, and thread processing of quality control still exist a series of problems, such as flexible tubing, the development of the expansion casing is still blank.

 

The oil well pipe is often subjected to the joint action of corrosive medium and alternating load (bending, vibration) in service condition, which will cause serious corrosion fatigue damage.The influence of environment, mechanical state and material properties on corrosion fatigue was analyzed.Crack initiation mechanisms include stress concentration at pitting pits, geometrical discontinuity of components, resident slip zone and surface film rupture, etc. Crack propagation mechanisms include anodic dissolution, active factors, surface energy reduction, product transfer and product film factors.The pipeThe pipeIt is pointed out that the key and difficult point in the study of corrosion fatigue of oil well pipe is the corrosion fatigue mechanism under the corrosive environment.On the basis of field test data, corrosion fatigue research combined with test and numerical simulation method can lay a foundation for the fracture theory of oil well pipe, and also provide a guarantee for the safe production of oil and gas Wells.
