【摘要】 根据重晶石浆配方,研究了影响重晶石塞形成的几个因素:pH值、膨润土含量、重晶石来源、FCLS加量及配浆水矿化度等。实验结果表明,膨润土含量与重晶石重量比小于1.5％、pH值为10左右和配浆水尽可能用淡水有助于形成好的重晶石塞。更多还原

【Abstract】 Several influence factors of barite plug such as pH value , bentonite content ,barite quality, dosage of FCLS are discussed . It is indicated that it is beneficial to form barite plug in the following condition : weight ratio of bentonite to barite below 1. 5 percent , pH value about 10 , and fresh water .更多还原
