[Abstract]:Under the increasingly tight environment of petroleum resources, improving the automation level of oil drilling, resource drilling and other production processes, improving the efficiency of key parameters detection, reducing energy consumption and reducing environmental pollution are the research focus of related technology developers. The rheological parameters of drilling fluid are important parameters which must be closely monitored in various drilling production processes. At present, the measuring equipment used is mainly imported from the United States and Germany, and the price is expensive, most of them are installed in the laboratory, and a few can be carried to the production site. The method of measurement is offline. According to the present situation at home and abroad, a set of straight-tube on-line viscosity measuring device is designed. The device is mainly composed of two parts: measurement system and data acquisition and processing system. The measuring system is mainly composed of four parts, one) four groups of pressure sensors with different diameters of 4 sections of a constant current pump, a thin tube with different diameters, and a flow meter. Coriolis Flowmeter is used to measure the density, temperature and flow rate of drilling fluid, the PH value of rheological parameters is measured by capillary tube and the temperature of environment is measured by two end temperature sensor. Automatic measurement and data acquisition are realized by microprocessor, and data storage and processing are realized by PC computer. The data acquisition and processing system consists of minimum system, data storage module, communication module, switch output module, analog input module and so on. The measuring range of apparent viscosity of the device is 5-150mPa s, and the measuring precision can meet the requirement of 5%. It can be used to measure the viscosity of drilling fluid in real time and online instead of rotary viscometer. In this system, STM32F407 microcontroller based on ARM Cortex-M4 kernel is selected as the core processor, and a real-time measuring model of rheological parameters of drilling fluid is established, which takes differential pressure, flow rate, density and temperature as auxiliary variables and apparent viscosity as dominant variables. Finally, the paper debugs the viscometer in the laboratory. The debugging results show that the viscometer has strong anti-interference ability, stable operation and safe and reliable operation. The developed product has the advantages of simple operation, short time consuming and convenient remote transmission of the measured results. It can fundamentally change the existing measuring mode of rheological parameters of drilling fluid and improve the measuring efficiency of parameters such as rheological property of drilling fluid. It also lays a solid technical foundation for promoting the progress of drilling production technology and improving the level of drilling production automation, and has strong market demand.
