Eliminating ＂Fish Eyes＂ and Mitigating Formation Damage through Advanced Shear Pump Technology
In the formulation of high-performance drilling fluids, the oilfield shearing pump is indispensable for regulating rheological parameters. High-molecular-weight polymers (such as PAC and PHPA) are critical materials, but their ultra-high molecular weight often leads to partially hydrated agglomerates upon water contact. Without a high-efficiency shear pump, polymers and bentonite fail to receive the necessary mechanical dispersion, resulting in fish eyesmasses that are viscous externally but dry internally. This incomplete dissolution causes expensive chemicals to be wasted via shale shakers and triggers risks like wellbore instability and differential pressure sticking. Furthermore, these unhydrated particles can plug formation pores, leading to irreversible reservoir damage and reduced pr
