In view of this, a plugging construction operation is currently performed for the above-described situation, and in the plugging construction operation, a field circulation tank is generally used to prepare plugging slurry. The Chinese patent document with the publication number of CN114412397A discloses a workover rig mud circulation system and a method, the workover rig mud circulation system comprises six circulation tanks, a weighting pump, a mud pump, an output pipe network and an inhalation pipe network, wherein the six circulation tanks are respectively one to six tanks, the first tank comprises a vibrating screen, a sand settling bin and a degassing bin, the second tank is provided with a gravity settling bin and a water feeding bin, the third tank, the fifth tank and the sixth tank are respectively provided with a water feeding bin, the fourth tank is provided with a grouting bin and a water feeding bin, the mud pump is connected with the water feeding bins in each circulation tank through an external pipeline, the grouting pump is arranged in the grouting bin, the gravity settling bin is internally provided with a gravity settling tank, an inhalation pipe network is arranged between the circulation tanks, the bottom of the circulation tanks is provided with an output pipe network, the inhalation pipe network and the output pipe network are all provided with valves, and the weighting pump are communicated with each circulation tank through the output pipe network and the inhalation pipe network, and the problems that the existing mud circulation system is not compact in structure, high in moving and installation difficulty, large in occupied area and inconvenient to regulate and control are solved. In the prior art, the plugging mode is to use a No. 6 circulating tank as a plugging drilling fluid preparation tank based on a slurry circulating system structure similar to the structure, pump the drilling fluid or clear water in the circulating tank by a heavy pump, and add a plugging material to prepare the plugging drilling fluid by matching with a spraying funnel. After the configuration is completed, the plugging function is realized by injecting the slurry into the well through a slurry pump. This approach has the following problems:

1. the circulating tank is used for mixing slurry, so that the effective volume of the ground drilling slurry is occupied, and the underground safety cannot be ensured under the condition that a large amount of drilling liquid in the circulating tank is lost.
