Improving the Performance of Filter Loss Reducer Lignite Resin with Ultrasonic Induction
-
摘要: 按照SY/T 5679—2017标准配制褐煤树脂-膨润土水基钻井液。在高搅工序后将超声波输入到钻井液中,考察超声振动对钻井液各种胶体性能的影响,目的是探究一种配浆新方法,用于提升现存处理剂性能。实验结果显示,超声振动能导致钻井液滤失量和滤失速率显著降低,随着超声波功率或作用时间的增加,滤失量持续降低;除此之外,超声振动轻微降低了钻井液的表观黏度;在20 kHz、850 W和14 min的超声条件下,淡水钻井液API和HTHP滤失量的最大降幅分别为26.7%和27.6%;盐水钻井液中压和高温高压滤失量的最大降幅分别为29.5%和32.7%;滤饼厚度也在超声振动后降低30%~35%。通过粒径分析、吸附实验和扫描电镜观察发现,超声振动能降低膨润土颗粒平均尺寸,增加褐煤树脂在膨润土上的吸附量,从而导致钻井液在压差作用下形成更加致密的薄滤饼。研究表明,超声辅助配浆技术利于提高褐煤树脂及其钻井液的滤失性能。声空化机制负责解释上述所有现象。Abstract: A water based mud was formulated with lignite resin and bentonite in laboratory in accordance with the standard SY/T 5679—2017. After agitating the mud with high-speed mixer, the mud was treated with ultrasonic wave to investigate the effects of ultrasonic vibration on the colloidal properties of the mud. The purpose of this test is to find a new way of preparing mud with which the performance of the existing mud additives can be improved. The test results show that ultrasonic vibration can remarkably reduce the filtration rate of the water based mud formulated. In the test the filtration rate of the mud is continuously reduced at increased power of the ultrasonic wave and in the length of time the ultrasonic wave is working. Furthermore, the apparent viscosity of the mud is slightly reduced by the action of the ultrasonic wave. With an ultrasonic wave of 20 kHz/850 W acting on the mud for 14 min, the API and HTHP filtration rates of the water based mud are reduced by 26.7% and 27.6% (both maximum reductions) respectively. The thickness of the mud cakes is also reduced by 30%-35% after the action of the ultrasonic wave on the mud. Filtration test on a brine mud shows that the API and HTHP filtration rates are reduced by 29.5% and 32.7% (both maximum reductions) respectively after the action of the ultrasonic wave. Particle size distribution analysis, adsorption experiment and SEM observation show that ultrasonic wave is able to reduce the average size of the bentonite particles and increase the adsorptive capacity of the lignite resin on the particles of bentonite, thereby helping form a denser thin mud cake under the action of pressure differential of the mud. Laboratory studies show that mixing new mud with ultrasonic wave is beneficial to improving the filtration property of lignite resin water based drilling fluids. This performance of ultrasonic wave is the so-called “acoustic cavitation mechanisms”.
