The utility model discloses an oil field additive mixing device, in which a discrete cover is arranged at the lower end of the rotating shaft, and a number of throwing holes are arranged on the part of the discrete cover near its edge. The lower side of the edge part of the discrete cover is an inner bracket fixed on the inner wall of the tank body, and a ring raceway containing several balls is arranged between the edge part of the discrete cover and the inner bracket ring, which is discrete. When the cover rotates, the friction between the edge part of the discrete cover and the inner bracket ring can be effectively reduced, and the service life of the discrete cover can be improved. The middle part of the discrete cover is opposite to the liquid inlet pipe. The mixed solution enters the tank body from each liquid inlet pipe separately, and falls into the inverted conical bowl part of the discrete cover far from the throwing hole. At this time, the discrete cover is in a rotating state, which makes the middle part of the discrete cover rotate. In turn, each solution to be mixed is immediately mixed. At the same time, under the action of centrifugal force, the mixed solution throws away the discrete cover from the exit hole and falls into the bottom of the tank. Finally, it is discharged from the outlet pipe controlled by the control valve.

一种油田助剂混合装置
本技术属于石油开采用剂的
,尤其涉及一种油田助剂混合装置。
技术介绍
油田助剂,亦称油田化学剂,是指解决油田钻井、完井、采油、注水、提高采收率及集输等过程中所使用的药剂。油田助剂品种类繁多,分类方法也较多,根据我国石油天然气行业使用的油田助剂类型代号标准,可将油田助剂分为通用化学品、钻井用化学品、油气开采用化学品、提高采收率用化学品、油气集输用化学品和水处理用化学品六类。目前国产油田化学品已达300余种,年消耗量超过50000t。为了存储方便,一般油田助剂在使用前进行混合,但是现有的混合装置一般采用电机带动搅拌轴在罐体内转动的形式,需要先搅拌混合后排出,工作效率较低,难以边混合边排出,能够有效提高混合工作效率。
技术实现思路
