The portable microorganism paraffin removal and control bacterial liquid injection metering device comprises a reducing pagoda joint, a first high-pressure hose, a stainless steel pipe, a flow meter, a gate valve, a second high-pressure hose and a three-way joint, the reducing pagoda joint is connected with the first high-pressure hose, the first high-pressure hose is connected with the stainless steel pipe, the stainless steel pipe is connected with the second high-pressure hose, and the flow meter is connected with the gate valve, the three-way connector is arranged at the end of the second high-pressure hose, and the flow meter and the gate valve are arranged on the stainless steel pipe. According to the portable microorganism paraffin removal and control bacterial liquid injection metering device, the liquid level height difference in a tank car can be used for metering the microorganism bacterial liquid entering a well, a pump is not needed, power connection is not needed, and the portable microorganism paraffin removal and control bacterial liquid injection metering device has the advantages of being high in measuring precision, wide in flow range, good in repeatability, simple in structure, small in appearance size, light in weight, easy to install, convenient to read and the like.

Description

technical field [0001] The invention relates to the technical field of petroleum engineering, in particular to the technical field of oil well wax removal and prevention. Background technique [0002] In high waxy oil wells, wax deposition is the main problem that seriously affects the normal production of oil wells. Wax usually exists as a liquid under formation conditions. During the production process, as the temperature and pressure drop and light components continue to escape, the ability of crude oil to dissolve wax decreases, and wax begins to crystallize, precipitate, accumulate, and continue to deposit. Waxing. Wax deposits on the pipe rod, resulting in reduced oil flow channels, increased oil flow resistance, heavier suspension loads, increased power consumption and material consumption, and wax stuck. Therefore, in order to maintain normal production in wax deposit wells, regular wax removal and maintenance is required, otherwise it will cause wax stuck, and the...

Problems solved by technology

At present, pump trucks are generally used in the injection process of microbial bacteria liquid, and the requirements for pumping and metering are met at the same time. However, because the metering accuracy of most pump trucks is not high, the injection volume of microbial wax-removing and anti-wax bacteria liquid is small ( 0.3-2.0m 3) , and for oil wells with zero casing pressure, no extra injection power is required

Therefore, the pump truck cannot meet the measurement requirements of microbial wax removal and anti-wax construction sites, and it will cause waste of resources when used on oil wells that do not require power injection
