Abstract

The invention discloses a chemical dosing device for oil extraction, and relates to a chemical dosing device. The device comprises a water storage tank, wherein a horizontal fixing rod is fixedly connected to the top of the water storage tank, a supporting stand column is fixedly connected to the right side of the upper portion of the horizontal fixing rod, a chemical box is fixedly connected to the top of the supporting stand column, a longitudinal discharging pipe is fixedly connected to the bottom of the chemical box, a lateral connecting pipe is fixedly connected to the middle of the leftside of the longitudinal discharging pipe, a first one-way valve located above the lateral connecting pipe is fixedly connected to the inner side of the longitudinal discharging pipe, a second one-wayvalve located above the lateral connecting pipe is fixedly connected to the inner side of the longitudinal discharging pipe, a left-right sliding block is slidably connected into the lateral connecting pipe, and the left side of the left-right sliding block is fixedly connected with a driving horizontal rod. The device is simple in structure and convenient to use, the chemical dosing speed and efficiency of the device can be adjusted by controlling the position of a limiting adjusting bolt in use, and in addition, the device can disperse added chemical through transmission of a transmission belt, and the chemical dosing effect can be well ensured.

Description

technical field [0001] The invention relates to a dosing device, in particular to a dosing device for oil production. Background technique [0002] Oilfield dosing devices are widely used in oilfield development, but they often encounter problems such as thick oil, wax formation, and corrosion during work, which will bring a lot of trouble to normal work. In order to solve these problems, it is often necessary to add some chemicals . [0003] Antiscalant is a commonly used chemical additive. The principle is to add the antiscalant aqueous solution into the reinjection water to inhibit the formation of scale. Oilfield water scaling is an inevitable problem in oilfield production. It becomes more and more prominent with the increase of oilfield water output. Scaling problem seriously affects oilfield production. The oil production process adopts sewage reinjection treatment, and the reinjection water contains a large amount of calcium, magnesium, strontium, and barium plasm...
