[0017] The utility model will be further described below in combination with specific embodiment, as Figures 1 to 3 shown:

[0018] Embodiment 1: a kind of oil-based petroleum additive dilution device, including dilution tank 1, the lower end of dilution tank 1 is provided with the lower liquid inlet pipe 2 extending into dilution tank 1, the lower liquid inlet pipe 2 is connected with oil-based petroleum additive storage tank, the lower liquid inlet pipe 2 is provided with opening valve, the flow of oil-based petroleum additive is controlled, the upper end of the lower liquid inlet pipe 2 is provided with liquid distribution disc 3, the side surface of liquid distribution disc 3 is provided with a plurality of liquid outlets 4, and the oil-based petroleum additive entering the lower liquid inlet pipe 2 flows out from each liquid outlet 4.

[0019] The upper end of the distribution disc 3 is provided with a conical flow guide 5, and an upper liquid inlet pipe 6 extending above the dilution tank 1 is vertically arranged above the conical flow guide 5. The upper liquid inlet pipe 6 is connected with a storage tank of dilution liquid. The dilution liquid flows out of the upper liquid inlet pipe 6 and falls on the conical flow guide 5. The conical flow guide 5 guides the dilution liquid to the periphery. The dilution liquid contacts and mixes with the oil-based petroleum additive in the falling process. After mixing, the dilution liquid falls into the dilution tank 1. The mixing is uniform and the mixing efficiency is high. The lower end of the dilution tank 1 is provided with a liquid outlet valve 7 for discharging the diluted oil-based drilling fluid.

[0020] In example 2, the oil-based petroleum additive dilution device includes a dilution tank 1. The lower end of the dilution tank 1 is provided with a lower liquid inlet pipe 2 extending into the dilution tank 1. The lower liquid inlet pipe 2 is connected with a storage tank of oil-based petroleum additive. An opening valve is arranged on the lower liquid inlet pipe 2 to control the flow of oil-based petroleum additive. The upper end of the lower liquid inlet pipe 2 is provided with a distribution disc 3. A plurality of liquid outlets 4 are formed in the side of the distribution disc 3. The oil-based petroleum additive entering the lower liquid inlet pipe 2 flows out of each liquid outlet 4.

[0021] The upper end of the distribution disc 3 is provided with a conical flow guide 5, and an upper liquid inlet pipe 6 extending above the dilution tank 1 is vertically arranged above the conical flow guide 5. The upper liquid inlet pipe 6 is connected with a storage tank of dilution liquid. The dilution liquid flows out of the upper liquid inlet pipe 6 and falls on the conical flow guide 5. The conical flow guide 5 guides the dilution liquid to the periphery. The dilution liquid contacts and mixes with the oil-based petroleum additive in the falling process. After mixing, the dilution liquid falls into the dilution tank 1. The mixing is uniform and the mixing efficiency is high. The lower end of the dilution tank 1 is provided with a liquid outlet valve 7 for discharging the diluted oil-based drilling fluid.
