Problems solved by technology

[0003] 1. The medicine is added to the pipeline at one time, and the medicine cannot continue to play a role;
[0004] 2. The condition of no water seepage and dilution at the wellhead makes the agent hang on the wall seriously, so that all the agents cannot reach the bottom of the well;
[0005] 3. The labor intensity of the workers is high, the work efficiency is low, and the intelligence of the operation and control of the oil well group is low;
[0006] 4. When adding chemicals to oil production well groups, the consumption of chemical agents is relatively large, and it is impossible to add chemicals to oil pipelines in a targeted manner, and there is a phenomenon of waste of chemicals

Embodiment 1

[0058] Such as Figure 1-2 , Figure 7 and Figure 9 As shown, a dosing device for an oil production well group, a dosing device for an oil production well group, including a first box body 1, a box door 2, a control panel 3, and a thickening agent box 4 , descaling agent kit 5, water pipe 7, ball valve 12, pressure detector 14, pipe wall thickness detection sensor 19, fluid velocity detection sensor 23, second casing 24 and crude oil pipeline 25.

[0059] On the inner wall of one side of the first box body 1, a thickening agent cartridge and a descaling agent cartridge 5 are symmetrically fixed by bolts, and a mixing mechanism 6 is communicated with the bottom of the thickening agent cartridge 4 and the descaling agent cartridge 5, wherein, The mixing mechanism 6 includes a first housing 601 and a partition 602. The partition 602 divides the first housing 601 into two halves, and a first The drug guide tube 8, the second drug guide tube 9 is installed at the bottom of the ...

Embodiment 2

[0068] Such as Figure 5 As shown, the drug discharge mechanism 15 also includes a rocking wheel 152, a first threaded rod 153, a push block 154 and a diaphragm. The rocking wheels 152 are symmetrically installed on both sides of the second housing 151, and are located at one end of the rocking wheel 152 and the second The first threaded rod 153 in the housing 151 is connected, and the second housing 151 is slidably connected with a push block 154, and an arc-shaped rubber plate 156 is installed on one side of the push block 154, and the arc-shaped rubber plate 156 and the push block A spring 155 is installed on the opposite surface of 154 , and a diaphragm is installed on the opposite surface of the two arc-shaped rubber plates 156 inside the second housing 151 .

[0069] Such as Figure 6 As shown, the liquid inlet and outlet control mechanism 16 also includes a second threaded rod 163, a placement groove 167, a fourth cock valve 162, a block 164, a vent 165 and a medicine ...

Embodiment 3

[0079] Such as Figure 1-3 , Figure 5 and Figure 6 As shown in the figure, the dosing device used in the oil production well group precisely dispenses the medicine.

[0080] The system modules used in the dosing device of the oil production well group are as follows: Figure 11 As shown, the functions of each module are: the liquid flow rate detection module is used to detect the flow rate value of oil in each pipeline in the oil production well group, which is realized by the fluid flow rate detection sensor 23;

[0081] The pipe wall thickness detection module is used to detect the pipe wall thickness value of each pipeline in the oil production well group, which is realized by the pipe wall thickness detection sensor 19;

[0082] The data acquisition and processing module is used to store the flow rate data value of oil flowing in the pipeline under constant temperature and pressure and the value of the wall thickness of the oil pipeline when it leaves the factory. Th...

Abstract

The invention relates to the technical field of dosing for oil production well groups, and discloses a dosing device and a dosing method for oil production well groups, which can be used for centralized detection of oil production well group pipelines and precise dosing at the same time, including a first box , box door, control panel, thickening agent kit, descaling agent kit, water pipe, ball valve, pressure detector, pipe wall thickness detection sensor, fluid flow rate detection sensor, second box body and crude oil pipeline; The installed thickening agent kit and descaling agent kit realize the dispensing of different types of medicines at intervals, avoiding adding the medicines into the pipeline at one time, and the medicines cannot work continuously. At the same time, the first medicine guide tube and the second medicine guide The setting of the drug pipe is based on the different situations in different pipelines, and different chemicals are correspondingly added to the oil pipeline, so as to avoid the waste of chemicals and improve the efficacy of the drugs.

Description

technical field [0001] The invention relates to the technical field of dosing for oil production well groups, in particular to a dosing device and a dosing method for oil production well groups in oil fields. Background technique [0002] After the oilfield enters the middle and late stage of development, the water cut will gradually rise. At the same time, the high water cut will cause scaling and corrosion of downhole pipelines and sucker rods. Normal and high wellhead back pressure. The solution to the above problems is to add various chemical agents to the well to achieve the purpose of corrosion inhibition, wax prevention and viscosity reduction, and reduce sticking, blocking and breaking of sucker rods, tubing and pumps. In order to maintain the normal production of oil wells due to accidents such as accidents, accidents, etc., the current method of dosing is to manually or quantitatively add the medicine from the annular space of the oil jacket at one time by using a ...
