随着钻井技术的飞速发展和钻井从计划体制走向市场的需要,走优质、高效、低耗钻井成为唯一出路,因此发展高效、优价能为钻井降低综合成本,显著提高经济效益的钻井液新技术新产品也就倍受青睐。特种树脂SHR正是适应这一需求而发展起来的一代钻井液新产品。SHR是由活化褐煤中间体与有机多元单体等经增效改质、接枝、缩聚、交 With the rapid development of drilling technology and the need of drilling from the planning system to the market, it is the only way to take high-quality, high-efficiency and low-cost drilling. Therefore, the development of new drilling fluid with high efficiency and high price that can reduce the comprehensive cost for drilling and significantly improve the economic benefit New technology products are also much favored. Special resin SHR is to adapt to this demand and developed a new generation of drilling fluid products. SHR is activated by lignite intermediates and organic multivariate monomers by the synergistic modification, grafting, polycondensation, pay
