IV. Product function
1. Improve the rheological properties of drilling fluid, have good portability, and obtain the best well cleaning effect.
2. It has a strong inhibitory effect on mud shale.
3. Good thermal stability, temperature resistance is greater than 180°C.
4. Excellent resistance to salt and calcium.
5. It can effectively prevent oil and gas layer pollution and increase oil and gas production.
6. Suitable for various water-based drilling fluids such as fresh water, sea water, and saturated brine.
7. Good compatibility with other treatment agents.
V. On-site application
The use in more than 5,000 wells in 16 oilfields in China has proved that the drilling fluid system composed of zwitterions FA367 and XY27 can be successfully applied in vertical wells, deviated wells, cluster wells, horizontal wells, ultra-deep wells, complex wells and various fresh water. Brine, saturated brine, low-density drilling fluid, and high-density drilling fluid systems can be used as both drilling fluid and completion fluid, and can stabilize the well wall, protect the productivity of oil and gas layers, increase drilling speed, and save drilling costs. Only based on Changqing. According to the statistics of the three oilfields in Sichuan and Turpan-Hami, the drilling fluid is basically not discharged during the drilling process, and the expansion rate of the well diameter is reduced to 4-10%. Matching with jet drilling, the average ROP can be increased by 8-30% (Changqing The average ROP in the Fanjiachuan area of the oilfield increased by 51%). Reduced damage to oilfield gas formations. The amphoteric ion polymer oil-in-water drilling fluid formulated with this agent was used in the Xiazijie structure in Xinjiang to drill oil layers, and the oil production increased by more than 20% on average, and the average oil recovery intensity increased by 50.8%. in addition. Zwitterionic FA367 has also been successfully used in polymer heavy mud and polymer brine heavy mud systems.
VI. How to use
The usual dosage of FA367 is 0.2% to 0.4% for fresh water and 0.7% to 1.5% for saturated salt water.
VII. Transportation and storage
The product should be protected from sun, rain, and packaging damage during transportation; the shelf life is one year.
