Description

A cleaning device for simulating a wellbore

technical field

The utility model relates to the field of foam drainage experiment devices in gas fields, in particular to a cleaning device for simulating a shaft.

Background technique

The wellbore simulator plays an important role in the evaluation experiment of determining the foaming ability of chemical agents in the gas field. After the wellbore simulator is used, the foam will adhere to the inner wall of the simulated cylinder. The conventional cleaning method is to pour the cleaning liquid from the top of the simulation device, and the foam and residual liquid in the cylinder will be brought out through the end of the simulated wellbore under the gravity of the water flow to clean the inner wall. However, this method cannot effectively and efficiently clean the cylinder. In the inner wall of the wellbore simulation cylinder, especially in the connection between the fixed section simulation cylinder and the adjustable section simulation cylinder of the directional well foam drainage wellbore model experimental device, there are often residual Residue, and a large demand for cleaning fluid.

Utility model content

The purpose of this utility model is to provide a cleaning device for the simulation device after measuring the foaming ability of chemical agents in the wellbore by using the airflow method of the simulation wellbore device.

The technical scheme of the utility model is as follows:

A cleaning device for a simulation device, which is characterized in that a short hollow pipe with one end closed is used as a cleaning head, the other end is connected to a water inlet hose connector, and spray holes with spray channels are arranged around the pipe wall.

When the experiment is completed and the simulator needs to be cleaned, put the cleaning head from the top of the simulation cylinder and turn on the cleaning liquid water source. At this time, the cleaning liquid is sprayed from the spray hole on the outer cylinder of the cleaning head to the tube wall, and the cleaning hose is slowly lowered. Clean the inner wall of the entire simulation cylinder.

The utility model connects the specially designed cleaning head through the water inlet hose, puts the cleaning head from the top of the simulation cylinder, and sprays the cleaning liquid to the inner wall of the simulation cylinder through the spray hole on the outer cylindrical surface of the cleaning head. Flush the inner wall of the fully simulated cylinder by lowering the hose.

The beneficial effects of the utility model are as follows:

The utility model changes the direction of water flow, and cleans the inner wall of the simulated cylinder in a targeted manner, with novel design; it can clean the cylinder simply, conveniently and efficiently, and saves more water than the way of directly cleaning the simulated device with cleaning liquid.

Detailed ways

As shown in Figure 1-2, a cleaning device for a simulation device uses a short hollow tube with one end closed as the cleaning head, the other end is connected to the water inlet hose connector, and spray channels with spray channels are arranged around the tube wall hole.

The short hollow tube may be made of glass.

When the experiment is completed and the simulator needs to be cleaned, put the cleaning head from the top of the simulation cylinder and turn on the cleaning liquid water source. At this time, the cleaning liquid is sprayed from the spray hole on the outer cylinder of the cleaning head to the tube wall, and the cleaning hose is slowly lowered. Clean the inner wall of the entire simulation cylinder.

The steps to use are:

(1) Place the connected cleaning head on the top of the simulation device;

(2) Turn on the water source and adjust the flushing water flow intensity;

(3) The connecting water pipe is lowered, and the cleaning head moves downward along the inner wall of the simulated cylinder;

(4) For places that are not easy to clean, it can stay properly to ensure the cleaning effect;

(5) After cleaning, take out the cleaning head.
