Core Viewpoint - The development of a multifunctional long-lasting polymer treatment agent by the Zhongyuan Petroleum Engineering Company has shown significant advancements in drilling fluid performance under extreme conditions, providing strong technical support for the efficient development of deep wells, ultra-deep wells, and shale gas horizontal wells [1][3]. Group 1: Technological Advancements - The new polymer treatment agent can maintain stable fluidity at high temperatures of 220°C, demonstrating excellent performance in high temperature, high salinity, and high density conditions [1][3]. - The introduction of the "suspended group" concept in molecular design allows the treatment agent to adapt to varying conditions, ensuring both fluidity during drilling and stability when stationary [2][3]. Group 2: Efficiency and Cost-Effectiveness - The new treatment agent consolidates multiple functions, reducing the number of required treatment agents from over ten to just two or three, leading to a reduction in total usage by over 30% [3][4]. - The cost of the new agent is comparable to common drilling fluid polymer stabilizers, while its performance surpasses that of traditional materials, achieving the goal of "low cost and multifunctionality" [3][4]. Group 3: Environmental Considerations - The production process utilizes "inverse micro-suspension polymerization" technology, which minimizes waste and pollution, resulting in a product that dissolves faster than traditional powders [4]. - The treatment agent has been tested in nearly 300 wells, with experimental results exceeding design indicators, indicating its practical applicability [4].
