Laboratory experiment of drilling fluid compounded by supersonic dispersing method

It is accidently found that the mud building bentonite powder can easily and homogeneously disperse in ultrasonic washing machine when using ultrasonic wave washing machine to conducting ultrasonic dispersing and particle measurement for drilling fluid samples. So mud mixing procedure is finished by adopting supersonic wave technology. The successful mud mixing for three wells using this technology demonstrate preliminarily that this method is of some extend scientific nature and certain application feasibility. On the other hand, further study on the techniques and facilities are needed if the supersonic dispersing method used in practical application.
