AziExpress Geosteering While Drilling Combined Tool

AziExpress® geosteering combination instrument (azimuth resistivity) is a precise geosteering tool, which is the research result of the major national scientific instrument project undertaken by Shenkai Company, and has completely independent intellectual property rights. It integrates measurement parameters such as azimuth resistivity, azimuth gamma, compensation resistivity, annular pressure, and wellbore temperature in one drill collar, with high integration. Azimuth resistivity is mainly used in complex formations and thin reservoir construction. It provides real-time edge positioning, reservoir tracking, oil-water interface detection and other functions while drilling, realizes precise geological guidance and wellbore trajectory optimization, and helps water saturation analysis, wellbore cleaning, and well kick and leakage prediction, ensuring that the drill tool passes through the high-quality parts of the reservoir, improving the drilling rate of high-quality reservoirs, single well production, and improving drilling safety.

Product Features Real-time analysis of various parameters combined while drilling is provided to help geosteering engineers achieve precise geosteering. Azimuth gamma, azimuth resistivity and compensation resistivity are used to calculate the direction, distance and oil-water interface of the formation boundary Optimize the drilling trajectory so that the wellbore can be drilled at the upper interface or sweet spot in the reservoir to increase the drilling rate of the reservoir sweet spot The azimuth resistivity detection distance is much greater than that of traditional resistivity tools, and formation changes can be detected longer in advance, which helps to improve the drilling speed and quality and reduce risks High temperature, high pressure, wear-resistant and sulfur-resistant enhanced design Integrated annulus pressure measurement, real-time transmission and calculation of ECD Integrated sidewall azimuth gamma, 16-sector imaging Can be customized with near-bit, rotary steering and other tools
