3. Practice contents
I. Safety education at factory entrance and labor discipline report
The three-level safety education includes safety education at factory entrance, safety education in workshop (team) and safety education in class (post). Three-level safety education at factory entrance is to enable workers to master the necessary basic knowledge of safety production as soon as they enter the factory, and lay a solid foundation for realizing safety production.
The person in charge of the factory first introduced the general situation of the factory.
The No.1 Oil Production Plant of Henan Oilfield is located in Nanyang Basin in the southwest of Henan Province, spanning five counties of Wancheng, Xinye, Tanghe, Biyang and Tongbai in Nanyang and Zhumadian, and the factory is located at the junction of tanghe county and Tongbai County. The First Oil Production Plant is a production unit with an annual output of 1.16 million tons of crude oil, which integrates oil production, water injection and oil and gas gathering and transportation. The oil production plant has four combined stations, one purification station, one oil storage station, three oil transfer stations and two heating stations. In the oil and gas gathering and transportation system of the whole plant, 27 three-phase separators, 53 heating furnaces, 21 crude oil storage tanks over 2111m3 and 31 oil transfer pumps are built.
Characteristics of the oil production plant:
The production points have many lines, long surfaces and wide dispersion, and there is no fence;
the external interference is serious and the safety management is difficult;
employees have weak safety awareness and poor technical quality;
there are many inflammable and explosive sites, which are dangerous.
Then the person in charge of the factory introduced relevant safety knowledge and received safety education. The general safety regulations include: 1. Safety management regulations for fire operation; Ii. regulations on the safety management of operations in confined spaces
iii. regulations on the safety management of temporary electricity use; Iv. regulations on safety management of construction operations
v. regulations on safety management of high-altitude operations; Vi. Safety management regulations for lifting operations
VII. Safety management regulations for ground breaking operations; Eight, high temperature operation safety management regulations
This paper introduces some of the related safety knowledge of the operation. Because the by-products of petroleum have great fire safety hazards, it is very important to prevent fire and explosion.
fire and explosion safety knowledge: oil and gas is a high molecular compound, which is flammable and explosive. Therefore, it is also a top priority to do a good job in fire safety in oil fields. The principle of fire control work is: prevention first, combination of prevention and elimination, and comprehensive management. In the struggle against fire, we must put prevention work in the first place, strictly implement measures in the system, and fundamentally grasp the initiative of fire prevention work; At the same time of active prevention, we must also be fully prepared ideologically, organizationally and materially. Once a fire breaks out, we must control the fire in time and effectively with the fastest speed, shortest time and best scheme, and minimize the loss.
Common fire extinguishing methods are as follows:
1. Cooling method: water or carbon dioxide fire extinguishing agent is directly sprayed on the burning object or the surrounding objects to achieve the purpose of fire extinguishing.
2. isolation method: evacuate or isolate the materials around the fire point to prevent the fire from expanding or reducing losses.
3. suffocation method: air or oxygen is isolated, and the fire is extinguished due to lack of combustion support.
4. Interruption of chemical reaction method: The reaction can be interrupted by using chlorodifluoromethyl bromide fire extinguishing agent to participate in the combustion reaction process.
Safety knowledge of safe use of electricity:
1. Personnel who are not formally trained are not allowed to operate, disassemble and install electrical equipment in production at will.
2. No one is allowed to connect wires, lights and electrical equipment without permission.
3. No one is allowed to operate with electricity when repairing the circuit without permission.
4. Formal electrical workers should be operated by one person and supervised by one person.
Safety knowledge to prevent mechanical injury:
1. According to the regulations, necessary safety accessories such as interlocking, self-locking, guardrails, platforms and handrails should be installed on mobile equipment.
2. During the operation of mobile equipment, maintenance and other project operations are not allowed.
3. Establish a listing system, such as: no closing, no running, no use, no climbing, etc.
Safety knowledge of preventing falling from high altitude:
1. Operators, outside electricians and electricians and welders must fasten their safety belts when working at high altitude.
2. All buildings with warning signs of no climbing are prohibited from climbing.
3. Under any circumstances, people should not be hoisted by cranes for aerial work.
Safety knowledge of preventing objects from hitting:
1. Operators must wear safety helmets when operating at the wellhead.
2. Outside electrician stringing and ground monitoring personnel must wear safety helmets.
3. No one is allowed to stand under the crane boom. Commanders must wear safety helmets.
The factory safety education also introduces a lot of related knowledge, so here are some of them. Through this education, I have a certain understanding of safety. In production and life, we must abide by the relevant operating procedures and act according to the rules, so as to nip in the bud, reduce the number of accidents, reduce the losses caused by accidents and improve production efficiency.
II. Various lecture reports (introduction of basic knowledge of HSE, basic knowledge of downhole operation, crude oil processing and transportation technology, and related knowledge of flowing wells)

III. Work of river metering station
During the work of metering station, we listened to some reports accordingly, which have been explained above. We mainly study the theoretical knowledge of various operation processes in the metering station, and the masters lead the team to the production line to observe. The whole work can be roughly divided into: 1. Collecting data; 2. Patrol the well to take samples; 3. Measure the oil and inject water; 5. Guarantee the pumping unit. After we ran the well, we learned relevant knowledge at the metering station.
beam pumping unit:
Its main function is to change the high-speed rotation motion of the motor into the slow reciprocating motion of the sucker rod.
working principle of beam pumping unit: when working, the power machine transmits high-speed rotary motion to the crank shaft through the belt and reducer, which drives the crank to rotate at low speed. The crank drives the walking beam to swing up and down through the connecting rod and the cross beam. The rope hanger hanging on the donkey's head drives the sucker rod string to reciprocate.
