'Daqing Underground' efficiently serves the oilfield with 'wisdom'

Digitization, informatization, and intelligence empower production to accelerate, improve efficiency, and enhance capabilities! The underground operation branch of Daqing Oilfield has completed the construction of a "smart underground" production safety integrated control platform with "one center, five platforms, and eight modules" as its core, further enhancing its ability to serve the oilfield and adding new impetus to achieve the goal of "one stability, three increases, and two improvements" in the oilfield.

Smart Underground "has opened up a new mode of efficient operation and management for" Daqing Underground "! What kind of 'wisdom' does it possess?

Real time controlled production, achieving a leapfrog improvement in efficiency

Arriving at the underground production command center of Daqing Oilfield, the large screen displayed the progress of the production and operation plan for the large-scale fracturing system in August, clearly showing detailed information such as the construction well number, category, plan, team, and progress.

The underground operation branch of Daqing Oilfield includes multiple businesses such as fracturing, well repair, and operations. There are hundreds of teams waiting for production organization arrangements on the front line, and multiple departments such as sand acid and liquid preparation need to be coordinated for production support on the back line. How to make all production chains under real-time control? How to enable the management "brain" to quickly grasp the overall situation and issue correct instructions?

After more than three years of continuous research and development, the production command center was born. It covers 102 functional points, including multiple command centers such as QHSE monitoring center and shale oil command center, as well as hundreds of operation and well repair teams, achieving efficient command that integrates "production operation, QHSE comprehensive monitoring, equipment control, material support, and technical services".

This subsidiary continues to promote the innovative integration of multiple technologies such as the Internet of Things, blockchain, and AR, creating a "smart underground" that enables three-level linear control of production and operation from "big screen - web end - APP end", achieving a leapfrog improvement in overall operational efficiency.

Real time online supervision, achieving intrinsic safety in production

Safety is the prerequisite for all work! At the beginning of building the "Smart Underground", this branch company integrated safety and environmental protection supervision work into it - promoting "work order management" for high-risk operations, carrying out "closed-loop management" for the entire QHSE supervision process, and focusing on "tracking management" for system data analysis.

The QHSE comprehensive supervision and management section of 'Smart Underground' has brought about a revolutionary change in the mode of safety and environmental protection supervision. From running on site early and late to real-time online supervision, we have achieved an upgrade from safe underground to green underground, "said Zhao Chang, Deputy Director of the Supervision Center, with great emotion.

Smart underground "has solved the problems of multiple supervision points, wide coverage, few personnel, discontinuous on-site supervision, and inability to supervise at night in the past. Since its launch, we have achieved full online and offline supervision of high-risk operations at both the first and second levels. The number of safety hazards has decreased by 28.6% year-on-year, and the timely rectification rate of supervision issues has reached 100%.

Real time information sharing, maximizing resource utilization

A phone call from the construction site of a tight oil horizontal well was made to the production command center, stating that the current construction pressure is high and the construction displacement cannot meet the design requirements for the well occupied by the hydraulic fracturing team. Remote guidance from experts is requested.

The production command center quickly contacted He Jian, the director of the fracturing room of the Engineering Geological Brigade. In just a few minutes, the video link was connected. First, acidify the area, then add sand in a multi-stage plug style with low sand ratio... "Through the screen, He Jian quickly understood the on-site situation and provided a solution to quickly solve the problem.

Intelligent platforms can achieve the sharing of human resources and the rational allocation of important materials. Xu Jiawen, the leader of the material team at the sand acid selection factory, said, "'Smart Underground' can also provide intelligent analysis and dynamic warning of inventory and demand, maximizing the ability to ensure material supply

One instruction goes directly to the scene, one set of cameras supervises the entire scene, and one platform realizes sharing... "Daqing Underground" is efficiently serving the oilfield with "wisdom" and is moving towards a new stage of high-quality development. (End)
