In cementing operations, the control of the fluid loss of cement slurry is directly crucial to the quality of cementing. Relying on its strong R&D and production capabilities, Kelioil has launched a variety of fluid loss reducers, including General type, Anti-inversion type, Anti-settling type, Seawater-resistant type, and low-temperature coagulation promoting setting type, to meet the needs of different cementing projects.
General Fluid Loss Reducer: A Widely Applicable Basic Product
The General fluid loss reducer is a basic product in KELIOIL's family of fluid loss reducers and is widely used. In the cementing operations of conventional oil and gas wells, after adding KELIOIL's General fluid loss reducer, the fluid loss of the cement slurry can be reduced to less than 50 mL, meeting the industry standard. In a certain oilfield in the Middle East, this product was used in the cementing operations of more than 100 conventional oil wells. By forming a dense filter cake, the performance of the cement slurry was stable, and the high-quality rate of cementing exceeded 90%. In addition, the cost of this product is 15% lower than that of similar products, and it has strong compatibility. It can be matched with various cements and admixtures, effectively reducing the cementing cost and improving the operation efficiency.
Anti-inversion Fluid Loss Reducer: A Reliable Assistant for Deep Well Cementing
During deep well cementing operations, the pressure in the well is complex, and the cement slurry is prone to inversion, leading to the failure of cementing. Through the design of a special molecular structure, KELIOIL's Anti-inversion fluid loss reducer can increase the cohesion of the cement slurry by 30%, significantly enhancing its shear resistance. In a certain ultra-deep well cementing project in Sichuan, with a well depth of 6,500 meters, a temperature of 180°C, and a pressure of 120 MPa, after using this fluid loss reducer, the cement slurry returned smoothly, and the cementing quality fully met the standard, laying a solid foundation for oil and gas production in deep wells.
Anti-settling Fluid Loss Reducer: Ensuring the Cementing Quality of Highly Deviated Wells
When cementing highly deviated wells, the particles of the cement slurry are prone to sedimentation under the action of gravity, affecting the cementing quality. KELIOIL's Anti-settling fluid loss reducer is added with a special Anti-settling component, which can evenly disperse the cement particles. In the cementing of a certain highly deviated well in Xinjiang, with a well deviation angle of 60°, after using this fluid loss reducer, the cement slurry remained uniform and stable within 12 hours, the strength standard deviation of the cement stone was controlled within 5 MPa, the bonding quality between the cement and the wellbore was good, and the channeling of oil, gas, and water was effectively prevented.
Seawater-resistant Fluid Loss Reducer: Improving the Fluidity of Cement Slurry
The Seawater-resistantfluid loss reducer aims to improve the fluidity of the cement slurry. During the cementing process, this product disperses the cement particles through electrostatic repulsion and steric hindrance, which can reduce the viscosity of the cement slurry by 40%. In the cementing operation of a certain long horizontal section well in Shengli Oilfield, with a horizontal section length of 1,500 meters, after using the Seawater-resistantfluid loss reducer, the cement slurry was pumped smoothly, the displacement efficiency reached over 95%, and the cementing quality was greatly improved.
Low-temperature coagulation promoting Setting Fluid Loss Reducer: Coping with the Challenges of Low-temperature Environments.
In cold regions or low-temperature well sections, the hydration reaction of the cement slurry is slow, and the setting time is long, affecting the progress of cementing. While controlling the fluid loss of the cement slurry, KELIOIL's low-temperature coagulation promoting setting fluid loss reducer can promote the hydration reaction at low temperatures. In a certain oil and gas field project in the Arctic region of Russia, with an operating temperature as low as -30°C, after using this fluid loss reducer, the setting time of the cement slurry was shortened from the original 48 hours to 24 hours, greatly improving the cementing efficiency in low-temperature environments.
KELIOIL's series of fluid loss reducers play an important role in different cementing scenarios with their unique properties. Whether it is a conventional oil and gas well, a complex deep well or highly deviated well, or a cementing operation in a low-temperature environment, KELIOIL can provide suitable fluid loss reducer products, providing a solid guarantee for the high-quality development of cementing projects around the world.
