Petroleum exploration and development equipment refers to comprehensive equipment for oil and natural gas exploration, drilling, development, storage and transportation, including various types of geophysical prospecting and logging equipment, drilling equipment, oil and gas production equipment, downhole operation equipment, oil and gas gathering and transportation Equipment, offshore drilling platform equipment, etc. and related accessories and tools; oil refining and petrochemical equipment refers to the complete set of equipment required in the whole process of oil and natural gas processing and conversion, including general equipment (such as various process compressors, expanders, etc.) , pumps and valves, etc.) and medical equipment (such as reactors, towers, heat exchange equipment, industrial furnaces, storage and transportation equipment, medical machinery, etc.). The equipment specifications and parameters of the oil refining and petrochemical industry are determined by the process of the oil refining and petrochemical industry. The oil refining and petrochemical industry is a process industry. The requirements for automation are high, and it is required to be able to run continuously and stably for a long period of time, so there are high requirements for the reliability of the equipment. The oil and gas exploration, development and production process is characterized by multiple links, complex technologies, and high individual requirements. The eight-sector Radial Cement Bond Tool (RBT) is used to measure the cementing quality between the casing and formation, to assure the asset owner of good hydraulic separation between producing and non-producing zones, and to evaluate the well integrity. Three feet downwards from the sonic transmitter is a radial piezoelectric receiver. Each sector of this receiver picks up the sonic signals echoed and converts to electric pulses. Each sector represents one section of the cement column, which means a complete cement map covering the whole circumference can be generated. Such problems as unwanted water or gas production, fluid migration in the annulus which results from poor cementing bond can then be detected and analyzed. The RBT tool is simple in mechanical design, has good sealing performance and is easy to maintain. Electrically, smart control is adopted. The circuitry is simple. All these ensure reliability of the tool.
