Description

Technical Field

[0001] The utility model relates to the technical field of drilling fluid additives, in particular to an automatic adding and stirring device for drilling fluid additives. Background Art

[0002] The main function of automatic addition and stirring of drilling fluid additives is to add various additives to the drilling fluid and mix them evenly by stirring to improve the performance of the drilling fluid and meet different needs during the drilling process. The working principle is usually to drive the stirring device through a motor so that the additives are evenly distributed in the drilling fluid during the stirring process, which can improve the addition accuracy and mixing effect of the additives, reduce manual operations, reduce labor intensity, and at the same time improve the quality of the drilling fluid and drilling efficiency. It is widely used in oil drilling, natural gas drilling and other drilling projects that require the use of drilling fluid.

[0003] Drilling fluid additives will produce a large amount of foam when added and stirred. If the foam is not removed in time, it will reduce the density and viscosity of the drilling fluid, affecting its ability to carry rock cuttings and cool the drill bit. The foam will occupy the volume of the drilling fluid tank, resulting in a reduction in the effective capacity of the drilling fluid, which in turn affects the drilling progress. The presence of foam may affect the normal operation of drilling equipment, causing equipment damage or shortening its service life. Utility Model Content
