Description

Technical field: [0001] The present invention relates to a drilling fluid evaluation experiment instrument, specifically, it integrates multiple drilling fluid high-temperature and high-pressure evaluation experiment technologies to achieve the multi-purpose purpose of one instrument, and is suitable for scientific research institutes, enterprises and institutions related to oil and gas drilling. High temperature and high pressure multifunctional dynamic evaluation tester for drilling fluid used in scientific research laboratories and product testing laboratories Background technique: [0002] With the continuous expansion of oil and gas exploration areas, the depth of oil and gas drilling is getting deeper and more difficult, and the requirements for drilling fluids are getting higher and higher. For deep well drilling, the formation temperature is high and the pressure is high, which requires the drilling fluid to have excellent performance under high temperature and high ...

AI Technical Summary

Problems solved by technology

At present, due to the bottleneck problems of high temperature and high pressure dynamic sealing and mechanical transmission and data sensing technology, the instruments and equipment used to test the dynamic performance of high temperature and high pressure drilling fluid are not ideal, especially under dynamic conditions, the pressure and temperature are low, which cannot meet the requirements of drilling fluid. Testing and research on the dynamic performance of liquid under ultra-high temperature and high pressure conditions. Some traditional instruments still have problems such as wrong test methods and cumbersome operation steps.

In addition, it is necessary to use multiple instruments to complete the comprehensive performance test of high temperature and high pressure on the drilling fluid.
