[0002] Solid well cementing additive is the chemical additive for improving cement slurry performance and ensuring solid well cementing quality in oil and gas drilling engineering. In solid well cementing operation, cement slurry needs to adapt to complex well conditions (such as high temperature, high pressure, salt and gypsum layer, lost layer, etc.), and solid well cementing additive adjusts the rheological property, thickening time, strength development and other key parameters of cement slurry, so as to ensure the effective sealing between casing and formation. The form of solid well cementing additive is diversified due to its function, composition and use requirement, mainly including solid state (powder, particle), liquid state (solution, emulsion) and composite form. At present, solid well cementing additive in powder / particle form is packaged in ton bags, for example, retarder: lignosulfonate (powder), citrate (particle); dispersant: polynaphthalene sulfonate (PNS, powder), polycarboxylate (PCE, microspherical particle); fluid loss additive: hydroxyethyl cellulose (HEC, powder), modified starch (particle); weighting agent: hematite (Fe2O3, fine powder); plugging agent: walnut shell scrap (particle), mica sheet (sheet-shaped powder) and the like. However, when ton bags are used to store solid well cementing additive, due to the gap between the material guide pipe and the opening of the ton bag, part of the dust or particle-shaped solid well cementing additive spills out of the ton bag, causing waste of solid well cementing additive and pollution to the surrounding environment.

[0003] Therefore, it is necessary to provide a new solid well cementing additive ton bag metering packaging equipment to solve the above technical problems. INVENTION CONTENTS
