Safety Management of Downhole Operation

This article will discuss various risk factors that may exist in the process of downhole operations. The problems and deficiencies in the safety management of underground operations are analyzed, and corresponding solutions are proposed for these problems.

Reasons for Paying Attention to Safety Management of Downhole Operations

Suppose a safety accident occurs in the downhole operation. In that case, it will cause serious economic losses to the enterprise and the country, and the personal safety of the relevant personnel will be affected. Therefore, it is very important to ensure downhole operations’ safety, stability, and efficiency. We need to pay attention to safety management in the drilling and production process.

We should try to avoid the occurrence of unsafe downhole operations and safety accidents and strive to control the occurrence of downhole operation accidents to zero.

Inadequate Safety of Downhole Operations

Downhole operation is a technological method to guarantee the regular manufacturing of oil and also water wells in the process of oilfield expedition and growth. Mainly include oil and water well maintenance, oil and water well overhaul, reservoir reconstruction, and oil testing.

During the long-term production process of oil and water wells, due to the interference of various underground liquids and gases and the action of gas flow, the well conditions will gradually deteriorate, corrode, eccentric wear, and various types of failures will occur, resulting in oil and water wells not producing normally. The downhole repair of oil and water wells with problems and failures to ensure normal oil and water well work, and a series of measures implemented to relieve oil and water well failures, restore or improve their production capacity in the process of repairing various downhole failures. The process is downhole work.

There are many construction points in underground operations involving various constructions, and the hidden dangers of safety are also more complicated. Due to the influence of factors such as humans, environment, equipment, and facilities, underground operations are highly dangerous.

Unsafe underground operation mainly refers to the forcible operation of underground workers without excluding unsafe factors such as unsafe conditions and unsafe behaviors. Unsafe behavior mainly refers to operating errors, ignoring safety, ignoring warnings, using unsafe equipment, venturing into dangerous places, etc.

Unsafe factors caused by machinery, facilities, and humans should be avoided as much as possible. Underground operators must eliminate unsafe operations, master certain safety knowledge, and at the same time strengthen safety awareness, so as to avoid unsafe operations and safety accidents to the greatest extent and ensure safe production.

Problems Existing in the Safety of Downhole Operation

1. Lack of safety awareness of downhole operators

Safety knowledge means that people always keep in mind the importance of safety and know what to do when faced with danger. When working at ordinary times, know how to operate and know what preventive measures, treatment measures, or emergency rescue measures to take in emergencies. However, the safety awareness of underground operators is often weak.

2. Inadequate safety management system

The underground operation sites are often in relatively remote areas, the construction environment is relatively poor, and there are great difficulties in the safety management of the construction site. The production tasks are tight, the construction personnel is many, the workload is large, the work intensity is high, and the production links are many, which leads to the lack of serious implementation of the safety management system.

3. Incomplete standardization scheme for downhole operation safety

A comprehensive safety management system should be established. In addition, a corresponding safety standardization scheme is established for each link in the production process of underground operations to ensure safe production, and the details must be sufficiently standardized.

Portable Workover Simulator

Actions to be Taken:

1. Strengthen the safety awareness education of underground operators.

2. Improve the safety management system.

3. Improve the safety standardization plan for underground operations.

4. Use simulation systems such as portable workover simulators and fracturing and acidizing simulator for downhole operations. The simulation system can give students an immersive experience through the 3D animation synchronized with the operating conditions. And it can use mathematical models to simulate various working conditions and parameters in petroleum engineering operations and strive to achieve the same effect as actual drilling operations. In this way, students can intuitively experience and quickly master the relevant knowledge and skills of fracturing and acidizing production.
