摘要
目前防塌剂的评价方法对于化学胶结类防塌剂(胶结、固化性能)缺乏针对性,具有一定的局限性。针对化学胶结类防塌剂的防塌机理,结合胶黏剂学科相关技术及评价标准,引入搭接抗剪强度参数,测试其作用于界面之间的胶结强度,建立了一种化学胶结类防塌剂防塌效果评价方法。经多次优化改进后的测试数据表明,该评价方法测试结果误差合理,其评价结果具有平行性、可靠性和科学性,可更有针对性地评价化学胶结类防塌剂的防塌效果。
Most methods presently used to evaluate the performance of anti-sloughing agents lack the specificity to chemical bonding anti-sloughing agents(bonding,solidifying),and thus cannot be used to evaluate this kind of anti-sloughing agents.Based on the mechanisms of chemical bonding anti-sloughing agents in preventing sloughing(or collapsing)of borehole wall,a method has been established to evaluate the performance of the chemical bonding anti-sloughing agents.The setup of the new method has borrowed some ideas and standards from adhesive science,and has introduced the parameter of lap shear strength to measure the bonding strength between two interfaces.After many times of optimization and improvement,data tested with this new method showed that the errors of the measurement results are reasonable,and the evaluation data have the properties of being parallel,reliable and scientific.The new method can be used to specifically evaluate the performance of the chemical bonding anti-sloughing agents.
