How to ensure the stability and safety of degreaser when using degreaser in oil drilling casing?
When using degreaser in oil drilling casing, ensuring the stability and safety of degreaser can be achieved through the following aspects:
1. ** Select the right degreaser ** : Select the degreaser suitable for specific oilfield conditions, especially under high temperature and pressure conditions, need to choose a degreaser that can maintain stability under extreme conditions. For example, the application of heat-resistant natural modified fluid loss reducer in oilfield drilling can reduce fluid loss, improve filter cake, and protect well walls.
2. ** Improve the temperature resistance of degreaser ** : With the increase of drilling depth and temperature, the stability of degreaser may be affected. Therefore, it is necessary to modify the degreaser to improve its temperature resistance, so that it can adapt to high temperature formation.
3. ** Calcium and salt resistance ** : Some degreasers also have calcium and salt resistance, which helps to maintain their stability and effectiveness in complex oilfield environments.
4. ** Optimize the preparation process of degreaser ** : By improving the preparation process of degreaser, its performance and stability can be improved. For example, the optimization of the preparation process of natural modified fluid loss reducer can improve its application effect under high temperature and pressure conditions.
5. ** Consider the environmental protection of degreaser ** : Choose environmental protection degreaser to reduce environmental pollution. For example, high-temperature clean fracturing fluid technology is used in oilfield development to adapt to high temperature and pressure conditions, reduce formation damage, and improve well productivity and recovery.
6. ** Ensure the safety of degreaser ** : During the use of degreaser, its safety should be ensured to avoid harm to operators and equipment. For example, the design and use of oil casing should consider its safety under high temperature and pressure conditions, adopt the combination casing string design method, and carry out triaxial stress strength check in the design of casing strength.
7. ** Technical research and innovation ** : Continue to carry out special technical research, establish a technical database, in-depth study of historical casing damage casing change well restoration technology and successful cases, to provide guidance and suggestions.
8. ** Integrated sand control construction ** : In view of the complex situation of high risk of pressure operation and difficult overhaul and killing, continuous tubing is used to control pressure punching sand inside the tubing to improve the success rate of sand control.
These measures can ensure the stability and safety of oil drilling casing when using degreaser, and improve the efficiency and safety of oil field development.
