China's first set of ultra-high temperature and high pressure CPLog logging equipment has been successfully applied

CNPC Logging Co., LTD. (hereinafter referred to as CNPC Logging) has successfully developed the first 230 ° C /170 mpa small-diameter instrument in China. The main technical indicators are of international advanced level, which can effectively meet the logging requirements of ultra-high temperature, ultra-high pressure Wells and ultra-deep horizontal Wells in complex well conditions. It provides strong equipment support for domestic ultra-deep oil and gas exploration and development and overseas market competition.

On May 18, spread the good news: medium oil logging company for the first time application of the independent research and development, 230 c / 170 million small diameter well logging instrument series, the successful completion of the thousand agent 1 well in dagang oilfield logging task, gen CPLog logging equipment 213 degrees Celsius maximum operation temperature records, which provide the interpretation of the evaluation data and testing proposal adopted by party a.

As oil "much starker choices-and graver consequences-in" major project of science and technology in China, the CPC logging on the basis of conventional instruments, breakthrough "based on MCM high integration, high temperature, high temperature and pressure on the mechanical structure and circuit process, small diameter agent array detector structure, complex borehole environment correction processing" four big technical bottlenecks, solves the ultra high temperature and high pressure environment adaptability, inclined horizontal well environment correction, Improved the system integration, to enhance the equipment reliability and stability, instruments and heat-resistant pressure indicators can reach 232 degrees Celsius, 172 million, and developed the collection and processing software module, form a complete set of tools and auxiliary measuring instrument, able to identify formation lithology, effective reservoir, accurate calculation of reservoir parameters such as porosity, permeability, saturation, To meet the logging requirements of ultra-deep Wells, horizontal Wells, side drilling and other complex well conditions.

At present, more than 40% of China's remaining oil and gas resources are distributed in deep strata below 5000 meters, and the exploration of deep and ultra-deep strata has great development potential in the future. CNPC's independent 230 ° C /170 mpa high temperature and high pressure logging series can fully meet the logging needs of deep and ultra-deep Wells in China, completely replace imported similar equipment, greatly reduce the cost of introduction, and have broad market space and sustainable application prospects.
