\nFAQ<\/h3>\n
\nPAC is primarily used as a fluid loss control agent, viscosifier, and rheology modifier; it helps reduce fluid loss, improve filter cake quality, and maintain the stability of the drilling fluid system.<\/p>\n
\nPAC-LV (Low Viscosity) is mainly used to control fluid loss while minimizing the impact on drilling fluid viscosity; PAC-HV (High Viscosity) controls fluid loss while providing a more significant viscosifying and rheology-modifying effect. Customers wishing to reduce fluid loss without significantly increasing viscosity typically prioritize PAC-LV.<\/p>\n
\nPAC is mainly used in water-based drilling fluids (WBM) and is applicable to fresh water, brine, and various polymer-based drilling fluid systems.<\/p>\n
\nPAC is a water-soluble polymer that helps improve the distribution of solid particles and the structure of the filter cake within the drilling fluid. It facilitates the formation of a denser, lower-permeability filter cake, thereby reducing the invasion of the liquid phase into the formation.<\/p>\n
\nYes. Appropriate grades of PAC exhibit good tolerance to saline environments and can be used in brine drilling fluid systems. However, specific salt tolerance should be verified through testing based on the type of salt, concentration, temperature, and product grade.<\/p>\n
\nIt can be used in drilling fluid systems within a certain temperature range, though elevated temperatures may affect polymer performance. For high-temperature wells, it is recommended to conduct hot-rolling aging and fluid loss tests based on actual bottom-hole temperatures and, if necessary, use it in conjunction with high-temperature-resistant fluid loss control agents.<\/p>\n
\nYes. In suitable water-based drilling fluid formulations, PAC can be used in conjunction with additives such as **KCl, K-PAM, PHPA, and Xanthan Gum** to achieve fluid loss control, shale inhibition, encapsulation, and the adjustment of rheological and cuttings-carrying properties.<\/p>\n
\nBoth can be used for fluid loss and rheology control in water-based drilling fluids. PAC typically emphasizes high-efficiency fluid loss control and compatibility with various drilling fluid systems; CMC also functions to increase viscosity and reduce fluid loss. The specific choice should be determined based on salinity, temperature, target viscosity, and fluid loss requirements.<\/p>\n
\nPAC-LV is the preferred choice when fluid loss is high, but the drilling fluid viscosity is already elevated or further viscosity increases are undesirable.<\/p>\n
\nPAC-HV is a suitable choice when there is a need to reduce fluid loss while simultaneously improving drilling fluid viscosity, suspension capabilities, and cuttings-carrying performance.<\/p>\n
\nYes. PAC helps form a dense, low-permeability filter cake, thereby reducing filtrate invasion into the formation and aiding in wellbore stability and reservoir protection.<\/p>\n
\nThe specific dosage depends on the drilling fluid system, salinity, temperature, solids content, and API\/HTHP fluid loss control targets. It is recommended to determine the optimal dosage through laboratory formulation testing rather than relying on a fixed addition ratio.<\/p>\n
\nStandard packaging is 25 kg\/bag; customized packaging is also available to meet specific customer needs or export\/shipping requirements.<\/p>\n
\nYes, technical documents such as COA, TDS, and MSDS can be provided. Specific parameters\u2014such as viscosity, fluid loss performance, moisture content, and purity\u2014are subject to the actual product grade and the test results of the specific batch.<\/p>","protected":false},"excerpt":{"rendered":"
