"Intelligent Guardian" Helps Stabilize Production and Increase Efficiency in Old Oilfields of Jianghan Oilfield

SINOPEC News Network News at 7pm on August 18th, Xiong Feng, an employee of the Production Command Center in Tankou Oil Production Management Zone of Jianghan Oil Production Plant, Jianghan Oilfield, was inspecting oil wells on the PCS system, and the system sent a "Wangxin 19 Station Yellow 50- He immediately asked the cadre on duty for instructions and made a tanker to pull oil to ensure the smooth operation of production
.
This is a microcosm of the plant's application of intelligent systems to improve work efficiency

Since the beginning of this year, Jianghan Oil Production Plant of Jianghan Oilfield has focused on the goals of the group company and the oilfield deepened application innovation and efficiency action plan, promoted the improvement of informatization application capabilities and application effectiveness, and created "intelligent guards" to help stabilize production and increase efficiency
.

"Clairvoyance" optimizes production

"Every day I go to work, I have to open the production information platform to check and compare the working condition information of each well.
I also need to conduct encrypted inspections and timely inspection and troubleshooting during the staff inspection window.
This is due to the'electronic eye' and the efficiency of production and operation.
It has been further improved
.
" On August 20, Zhong Chao, deputy manager of the Xingou Oil Production Management District, browsed the real-time video images sent back from 7 first-line sites on the computer, and said with satisfaction

Since the beginning of this year, the plant has used the oil and gas production information management system (PCS system for short) to create a production information platform, making it a "clairvoyance" covering the entire oil area, through centralized video monitoring, network wireless transmission, background data processing and complete Process automatic early warning, create an intelligent oil and water well management mode, change the traditional manual inspection of oil and water well management methods, not only reduce the labor intensity of staff inspection, but also increase the speed of emergency response
.

The Xingou Oil Production Management Zone is responsible for 5 major blocks including Xingou and Tuoshi.
There are many production sites and wide areas in the oil zone.
In particular, the 32 oil extraction sites are remote and scattered, making management difficult
.
To this end, the Jianghan Oil Production Plant's Science and Technology Information Management Center repeatedly communicated and cooperated with manufacturers to realize single well and pull tank parameter collection and remote control through RTU, etc.

"E-Doctor" saves energy and reduces consumption

On August 17, Ma Yixiao, a technician from the Oil Production Technology Research Institute of Jianghan Oil Production Plant, came to the Wang 99 well site to calculate and record the energy consumption data of the well on the spot
.
Well Wang 99 is an inefficient well with a daily output of only 0.

In terms of energy saving and consumption reduction, Jianghan Oil Production Plant established a comprehensive diagnosis model for oil wells through the PCS system this year, and realized functions such as summary analysis of unit pumping well conditions, and realized system optimization, energy saving and consumption reduction
.

Mechanical oil extraction is the main form of crude oil extraction in Jianghan Oil Production Plant
.
When the pumping unit is in good balance during operation, the power consumption is less; if the "joint is not correct", it will aggravate the mechanical wear of the equipment, and in severe cases, it will even cause the rod to break and the pumping unit to malfunction, resulting in increased energy consumption

In order to solve the above problems, the technicians and designers of Jianghan Oil Production Plant have made unremitting efforts to establish an "electronic doctor" comprehensive diagnosis model for oil wells in the PCS system.
Functions such as automatic calculation of work diagrams provide technical support for system optimization
.
Relying on the PCS system to automatically calculate the upstream and downstream active power of the pumping unit, technicians can use the advanced "power method" to adjust the balance, improve the working conditions of the oil well, achieve energy saving and consumption reduction, and at the same time free them from the tedious data acquisition and statistical work , So that they can concentrate on research and make quick decisions

　　In view of the fact that 5 oil wells such as Ma 13 Xie-19 and Ma 36 Xie 2-51 consume high electric energy due to eccentric wear of the pipe and rod, the comprehensive diagnosis model of the oil well of the PCS system is used to analyze, find the root of the problem, and adjust the pipe string structure.
, Hot washing and wax removal measures, effectively reducing power consumption
.
By changing the pump diameter of the new 93 Incline-2 well from 38 mm to 32 mm, and adjusting the stroke rate, the pump efficiency of the well has been increased from 12.

　　"Since this year, the production informatization team of each oil production management area of ​​Jianghan Oil Production Plant has optimized the polished rod power method to calculate production based on the actual oil well, and revised the basic parameters and production coefficients in a timely manner.
The compliance rate has reached more than 90%

　　"Treasure in the palm" eliminates safety hazards

　　On August 23, at the Guanghua Joint Station of the Gathering and Transportation Brigade, Huang Wei, the deputy head of the station, used an explosion-proof handheld smart terminal to take pictures of the construction site, then opened the "Jianghan Oilfield—Contractor Admission" WeChat applet to scan the construction personnel’s admission card On the QR code, the information of the 8 construction workers is at a glance, and the entire verification process took less than 10 minutes
.

　　Since the beginning of this year, the Jianghan Oil Production Plant has accurately and conveniently eliminated hidden safety hazards in contractors’ audits through the development of the "Direct Operation Link Permit System Mobile APP Application" and the "Jianghan Oilfield-Contractor Entry" WeChat Mini Program
.

　　All along, construction guardians need to check the construction personnel's information before starting construction, and only allow them to enter the site after confirming that they are correct
.
Due to the complicated information of the construction personnel, the phenomenon of contractors' fish-eyes mixed with beads has been repeatedly prohibited.
Not only is the data review time-consuming and laborious, there are also serious safety hazards
.

　　In response to this problem, the factory recently launched the first "Direct Operation Link Permit System Mobile APP Application" in the oilfield, making full use of explosion-proof handheld mobile terminals and mobile Internet technology to establish tickets and implement measures during the ticket processing process.
5 business links, realize the whole process control of operation permit
.
The time for issuance of work tickets has been shortened from 30 minutes for handwritten tickets to 10 minutes for electronic issuance, which greatly improves the efficiency of ticket processing
.

　　A few days ago, the factory also jointly developed a professional software-"Jianghan Oilfield-Contractor Entry" WeChat applet with the manufacturer
.
On-site safety monitoring only needs to enter the software interface to scan the QR code exclusive to the construction personnel, and all kinds of information including personal identity and the validity of special operation certificates can be retrieved at any time
.
After on-site trial, the audit efficiency has been greatly improved
.
Up to now, more than 200 construction sites in the whole factory have used this procedure for verification, and "Palm Treasure" has truly become a "good heart" for safety managers
.
