Saudi Arabia, as one of the world's largest oil producers, has abundant oil field resources. However, during the oilfield drilling process, technical challenges and environmental factors cause drilling operations to face many problems. As an important chemical additive, polyacrylamide fracturing fluid has been widely used in oilfield drilling due to its excellent performance.

Problems facing Saudi Arabian oilfield drilling

Common problems during oil field drilling in Saudi Arabia include:

1. High temperature environment: Saudi Arabia’s desert climate results in extremely high ambient temperatures in oil fields, which poses severe challenges to the stability and performance of drilling fluids.

2. High-pressure formation: Some oil fields are located in high-pressure formations, which increases the difficulty of wellbore stability and pressure control during drilling.

3. Complex geological structure: The underground geological structure of oil fields is complex, with multiple alternating rock layers, which can easily lead to problems such as well wall collapse and drill sticking.

4. Long-distance horizontal wells: With the advancement of oilfield development technology, long-distance horizontal wells are increasingly used, which places higher requirements on the lubricity and sand-carrying performance of drilling fluids.

Application advantages of polyacrylamide fracturing fluid

Polyacrylamide fracturing fluid plays an important role in solving the above drilling problems due to its unique chemical properties and excellent performance:

1. Excellent temperature stability: Polyacrylamide fracturing fluid has good high temperature resistance and can remain stable in high temperature environments, effectively preventing drilling fluids from failing due to high temperatures.

2. Good viscoelasticity: Polyacrylamide fracturing fluid has excellent viscoelasticity and can form a stable well wall in high-pressure formations to prevent well wall collapse and well leakage.

3. Excellent lubrication performance: During the drilling process of long-distance horizontal wells, the lubrication performance of polyacrylamide fracturing fluid is significant, reducing the friction and wear of drilling tools and reducing the risk of drill sticking.

4. Efficient sand carrying capacity: Polyacrylamide fracturing fluid can effectively carry drilling cuttings and sand particles, ensuring wellbore cleanliness and improving drilling efficiency.

Application case analysis

In an oilfield drilling project in Saudi Arabia, the drilling team encountered problems such as poor wellbore stability and frequent stuck pipes. After trying a variety of traditional drilling fluids to no avail, it was decided to use polyacrylamide fracturing fluid.

By applying polyacrylamide fracturing fluid, the drilling team successfully solved the following problems:

1. The well wall stability is significantly improved: The viscoelasticity of polyacrylamide fracturing fluid helps form a stable well wall structure, effectively preventing well wall collapse.

2. Reduced drill sticking: Due to the lubricating properties of polyacrylamide fracturing fluid, drilling tool friction is greatly reduced, and drill sticking is significantly reduced.

3. Increased drilling speed: The efficient sand carrying capacity ensures the cleanliness of the wellbore, significantly increases the drilling speed, and the project progress is smoothly advanced.

The application cases of polyacrylamide fracturing fluid in oilfield drilling in Saudi Arabia show that it has significant advantages in solving problems such as high temperature, high pressure, and complex geological structure. Through reasonable selection and application of polyacrylamide fracturing fluid, drilling efficiency can be effectively improved, ensuring the smooth progress of oil extraction, and providing strong technical support for oilfield development.
