Intelligent injection allocation device for manipulator in oilfield water injection room and control method of intelligent injection allocation device

Abstract

The invention provides an intelligent injection allocation device for a manipulator in an oilfield water injection room and a control method of the intelligent injection allocation device. The intelligent injection allocation device adjusts the valve opening of a water injection well instead of manual routing inspection, unattended operation is realized, the adjustment accuracy is improved, the manpower is reduced, the labor intensity is lowered, and the safety is ensured. The intelligent injection allocation device for the manipulator in the oilfield water injection room includes a horizontaltravelling mechanism, a vertical lifting mechanism, a rotary adjusting mechanism and a servo controller for controlling the work of each mechanism, and the servo controller is connected with an adjusting control unit in the water injection room, the rotary adjusting mechanism is installed on the horizontal travelling mechanism through the vertical lifting mechanism, the rotary adjusting mechanismis composed of a chuck and a rotary driving mechanism for driving the chuck to rotate, and a plurality of clamping pawls are arranged at intervals on the chuck. According to the intelligent injectionallocation device for the manipulator in the oilfield water injection room and the control method of the intelligent injection allocation device, the opening of each valve can be automatically and accurately adjusted according to monitoring information of the water injection room without manual intervention, the water injection needs of the water injection well are met, the degree of automation of the water injection room is increased advantageously, and the labor cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of petroleum exploitation, and in particular relates to a manipulator intelligent dispensing device and a control method for an oilfield water injection room. Background technique [0002] Water injection is an important means of oilfield development and production, and it is also a large energy consumer, accounting for about 40% of the total energy consumption of oilfields. How to rationally optimize and finely inject water is of great significance. [0003] According to geological requirements, the error of water injection flow rate should be within ±15%. The existing oilfield water injection room adopts manual control water injection method. When the underground pressure and pipe network pressure fluctuate, resulting in changes in the actual water injection volume of the water injection well, it cannot be adjusted in time. In addition Manually adjusting the water volume is based on experience, which is ti...

AI Technical Summary

Problems solved by technology

According to the on-site working conditions, single well adjustments are performed several times a day, and the process of adjusting the flow rate of a single well by a worker takes about 5 to 10 minutes, which is laborious and time-consuming, and the adjustment work in the water distribution room is a high-pressure environment operation, and manual adjustment is required on site. There are security risks

The water injection room keeps running 24 hours a day. If workers are equipped to monitor the operation all day, this will undoubtedly increase labor costs.
