Description

Vehicle-mounted skid-mounted oil well intelligent dosing device

technical field

The utility model relates to a vehicle-mounted skid-mounted oil well intelligent dosing device, which belongs to the technical field of auxiliary equipment for oil and gas exploitation. the

Background technique

In the process of oil production in oil fields, crude oil is lifted from the bottom of the well to the surface. Due to the influence of factors such as pressure and temperature changes, wax deposition, scaling and corrosion will occur on the surface of the wellbore string and the gathering and transportation pipeline, thereby affecting Oil well production causes problems such as high wellhead back pressure. At present, the main solution is to add various chemical agents such as wax remover, scale inhibitor, and corrosion inhibitor to purify the wellbore. It is manually added to the wellbore periodically on site. The workload is heavy and involves The area is wide, the management is difficult, and the operating procedures are cumbersome. Among them, the addition of casing gas to the wellbore has certain safety hazards. In addition, the installation process of the conventional wellhead fixed dosing device is complicated, the medicine cannot be completely injected into the bottom of the well, and it is easy to escape into the gas pipeline, which has many problems in actual production. the

Contents of the invention

The purpose of the utility model is to provide a vehicle-mounted skid-mounted oil well intelligent dosing device to solve the technical problem of dosing in the actual production of the oil well. the

Concrete technical content of the present utility model is as follows:

The integrated intelligent dosing box of this dosing device is loaded on the truck, and the intelligent control box, medicine storage box, water storage tank, explosion-proof hydraulic pump, electromagnetic three-way valve, self-priming pump, and oil well casing are skid-mounted on the dosing box. interface, the drain pipe of the medicine storage tank, the filter screen, the medicine suction pipe of the medicine storage tank, the replenishment pipe of the water storage tank and the drain pipe of the water storage tank. The two ports of the electromagnetic three-way valve are respectively connected to the drug storage tank and the water storage tank with a liquid level gauge inside, and the other port is connected to the quick interface of the oil well casing through the explosion-proof hydraulic pump. The bottom of the medicine storage box is connected to the sewage pipe of the medicine storage box, and the top inlet is provided with a filter screen, which is connected to the medicine suction pipe of the medicine storage box connected to the self-priming pump. The bottom of the water storage tank is connected to the drain pipe of the water storage tank, and the top is connected to the water supply pipe of the water storage tank. the

The dosing device adopts intelligent control, which can accurately measure the dosing amount, reduce the workload of dosing, ensure that the medicine is injected into the bottom of the well, and reduce the safety hazards in the dosing process. The dosing device is quick to connect, saves time and effort, has a compact structure, small volume, and is convenient to move freely. the

Detailed ways

Example:

The embodiment of the utility model is further described with reference to Fig. 1 and 2:

The integrated intelligent dosing box 13 of this dosing device is loaded on the truck 14, and the intelligent control box 1, the medicine storage box 2, the water storage tank 3, the explosion-proof hydraulic pump 4, the electromagnetic three-way valve 5, the automatic Suction pump 6, oil well casing quick interface 7, medicine storage tank sewage pipe 8, filter screen 9, medicine storage box medicine suction pipe 10, water storage tank replenishment pipe 11 and water storage tank sewage pipe 12. The two ports of the electromagnetic three-way valve 5 are respectively connected to the drug storage tank 2 and the water storage tank 3 with a liquid level gauge inside, and the other is connected to the oil well casing quick interface 7 through the explosion-proof hydraulic pump 4 . The bottom of the medicine storage box 2 is connected to the sewage pipe 8 of the medicine storage box, and the top inlet is provided with a filter screen 9, and is communicated with the medicine suction pipe 10 of the medicine storage box connected to the self-priming pump 6. The bottom of the water storage tank 3 is connected to the drain pipe 12 of the water storage tank, and the top is connected to the water supply pipe 11 of the water storage tank. the

Before the drug dosing device works, the drug is sucked into the drug storage tank 2 through the self-priming pump 6, and the water storage tank 6 is filled with water, loaded near the well group by the truck 14, and connected to the oil well shaft through the oil well casing quick interface 7 , close the casing gas valve, start the pre-set program, and the corresponding amount of medicine can be flushed to the bottom of the well with water. the

The dosing device is programmed and controlled by an intelligent control box 1 mounted on the truck 14, and can be disassembled at any time. The required power is provided by the engine of the truck 14, and the explosion-proof hydraulic pump 4 is provided by the hydraulic system driven by the engine.
