Collecting multi-channel sensory signals is a feasible way to enhance performance in the diagnosis of mechanical equipment. In this article, deep learning method combined with feature fusion on proposed. First, neural network (DNN) made up auto-encoders adopted adaptively learn representative features from signal and approximate non-linear relation between symptoms fault modes. Then, Locality Preserving Projection (LPP) utilized extracted signals. Finally, novel diagnostic model based...
Sandwich pipe, consisting of two steel tubes and a polymeric or cement-based material core layer, has been considered as an attractive solution for oil gas transporting in deep water. In this paper, the characteristic responses pressure capacity sandwich pipes having fiber-reinforced cementitious composites configuration under external hydrostatic were investigated. The interface adhesion behavior between composite surrounding was modeled based on inter-layer shear strength test experiments...
Buckling deformation of pipe in actual bore hole will limit the maximum running depth and is likely to further damage drilling pipe, causing huge losses. Therefore, buckling analysis necessary. In order investigate mechanical behaviour coiled tubing (CT), a test bench including vertical, bending horizontal segments an end-loading unit designed. this paper, method combined numerical calculation experimental validation used study inside-pipeline CT buckling. Based on investigation, influence...
Erosion wear at the key point of a drill string is very severe in gas drilling. The investigation shows that failure serious probability pipe and collar highest all string, near placement pin box often damaged. According to erosion theory, model established. rate solved using Grant Tabakoff formula. Different factors, such as injection volume, penetration (ROP), cuttings' diameter, shape factor, number, temperature annulus, are considered. result more than other locations on pipe. Because...
Hydrate formation and wax deposition in submarine pipelines hinder the transportation of oil gas. Pigging operation is an important means to ensure pipeline flow assurance. In this paper, idea coiled tubing (CT) intervening hydrate removal underwater put forward, feasibility method discussed from point view ultimate extension capacity tubing. To end, theoretical analyses experimental tests are performed on mechanical behaviour pipelines. The present paper mainly axial force transfer...
Coiled tubing (CT) has been widely used for oil and gas exploitation, however corrosion of CT under high pressure temperature (HPHT) environment was often reported, also induced failures welds were observed to occur during service. Corrosion related behaviors are not clear. Therefore, a study the resistance HPHT is carried out. In order efficiently evaluate welds, some test samples obtained by linear cutting out CT110 in service on site. The water from field as reagent simulate actual...
