Problems solved by technology

Among them, the preparation of profile control agents is all done manually, there are many types of drugs, frequent dosing, many deployment personnel, high labor intensity, high operating costs, and low work efficiency
Especially at night, due to unmanned supervision, inaccurate dosing often occurs, and the dosing time interval and dosage cannot be guaranteed
In addition, the non-standard dosing method leads to frequent failures of stirring motors, reducers, profile control pumps and other equipment, which directly affects the effect of water plugging and profile control operations

Abstract

The invention belongs to the technical field of oilfield profile control operation devices, and in particular relates to an integrated automatic drug adding and water plugging profile control device and method. The invention includes a single-phase dosing skid, a profile control main sled and a multi-phase dosing sled; the profile control main sled is connected with the single-phase or multi-phase dosing sled. The invention changes the mode in the prior art that multiple skid-mounted equipments are required for simultaneous handling and combined operation for water plugging and profile control operations, and the equipment required for water plugging and profile control with chemical dosing is integrated and skid-mounted, and now only one vehicle is required. The transport can be completed. The setting of the central control cabinet in the main skid of profile control operation realizes the automatic control of the dosing process, changes the working mode of manual proportioning and dosing in the prior art, and improves the accuracy and timeliness of dosing. The invention is not only easy to operate, but also reduces labor costs, labor intensity and safety risks; ensures the effect of dosing, and directly promotes the increase of crude oil production.

Description

technical field [0001] The invention belongs to the technical field of oilfield profile control operation devices, and in particular relates to an integrated automatic drug adding and water plugging profile control device and method. Background technique [0002] On-site construction of profile control and water plugging operations has many points, wide areas, and difficult management. Among them, the preparation of profile control agent is all done manually, there are many types of drugs, frequent dosing, many personnel, high labor intensity, high operation cost and low work efficiency. Especially at night, due to unsupervised, inaccurate dosing often occurs, and the dosing time interval and dosing amount cannot be guaranteed. In addition, the irregularity of the dosing method leads to frequent failures of equipment such as the stirring motor, reducer, profile control pump, etc., which directly affects the effect of water plugging and profile control.
