“…The formation of thick filter cake and the water infiltration into the deep formations will result in severe problems, such as wellbore instability, formation collapse, reservoir damage, high torque and drag and pipe sticking problems, resulting in a very significant decrease in the drilling efficiency and hydrocarbon productivity. [15,16] To resolve the above problems and achieve better performance of water-based drilling fluids during drilling operations, some additives have been widely employed to change the physicochemical properties and improve the applicable properties of waterbased drilling fluids. [8][9][10][11][12][13][14][15][16][17][18][19][20][21] According to the functions of additives and the requirements of drilling formation, the additives for drilling fluid can be classified into several categories, including filtrate reducers, shale control inhibitors, surface-active agents, lost circulation materials, emulsifiers, foaming agents, defoamers, calcium reducers, corrosion inhibitors, pH-control additives, bactericides, temperature stability agents, viscosity modifier, alkalinity, pipe-freeing agents, lubricants, flocculants, dispersants, thinners and weighting materials.…”

“…Just as the name implies, the principal function of filtrate reducers is to minimize the fluid loss into the formations by the formation of a thin impermeable filter cake on the borehole wall, which is vital for drilling fluid systems to maintain the rheological property, create a stable hydrostatic pressure and ensure the stability of wellbore. [15,16] The ideal filtrate reducers should be able to create a thin and impermeable filter cake on the wellbore walls as soon as possible and then prevent filtrate and particles from entering the formations. A great number of substances have been used as filtrate reducers.…”

The ever‐increasing consumption of fossil energy highlights the urgent need to develop technologies to ensure the efficient drilling and exploration of oil and gas resources mainly distributed in deep and ultra‐deep layers. The complex geological conditions in deep formations with the feature of high temperature, high pressure and high salinity result in some very high requirements for the performance of drilling fluids. Various additives were demonstrated to decide the physicochemical properties and functional characteristics of water‐based drilling fluids that have been widely used to drill over 80% of wells. As one of the most crucial and most widely used additives in water‐based drilling fluids, various polymeric filtrate reducers play an important role in minimizing fluid loss, maintaining wellbore stability, ensuring drilling safety and efficiency as well as avoiding formation damage. Herein we comprehensively summarized the design, preparation and applications of polymer‐based filtrate reducers for fluid loss control in drilling operation. The spotlight is centered on the design strategies and structure‐property‐performance relationships of polymeric filtrate reducers to minimize fluid loss under high temperature, high pressure, and high salinity conditions in the deep formation. Future perspectives for achieving excellent comprehensive performance are also discussed to motivate new strategies and technologies to design and develop high‐performance water‐based drilling fluids with optimal rheological and filtration properties.This article is protected by copyright.

“…Generally, modified natural materials are the main choice of environmentally friendly additives in drilling fluids, 12 which are applied early and in large amounts, and can effectively adsorb on the surface of clay particles and promote the hydration of clay, such as polyanionic cellulose, 13 carboxymethyl starch, 14 xanthan, 15,16 modified starch, and starch graft polymers. 15,17 However, their high-temperature resistance is always poor.…”

“…At present, chemical modifications such as etherification , and grafting can effectively solve the temperature resistance problem of naturally modified fluid loss additives at low and medium temperatures. However, the high-temperature resistance of most of the developed naturally modified fluid loss additives is still insufficient, which can not meet the drilling needs of complex formations . Most of their temperature resistance does not exceed 150 °C.…”

With the continuous improvement of environmental protection requirements in the drilling fluid industry, the research of environmentally friendly additives has been widely discussed. Modified starch is a typical natural material and has been usually used as an environmentally friendly fluid loss additive. However, their high-temperature resistance is poor and limits their application. In this study, a composite fluid loss additive (STA) was prepared by reverse emulsion polymerization using corn starch and alkyl glycoside as raw materials and epichlorohydrin as the cross-linking agent. The molecular structure, thermal stability, and microstructure of STA were characterized, and its filtration properties were systematically evaluated. Results demonstrated that the thermal decomposition temperature of STA was 324 °C and significantly higher than that of corn starch. STA was irregularly spherical in an aqueous solution, and its surface presented a porous structure. Moreover, STA was easily biodegradable with a BOD/CODcr ratio of 19.2%. Filtration tests showed that the temperature resistance of STA could reach 170 °C, and 3% of STA reduced the fluid loss volume of 4% bentonite suspension by 62.71%. In comparison, the filtration performance of STA was better than those of corn starch and commonly used sodium carboxymethyl starch. On one hand, STA had a cross-linked structure and a long paraffin chain, providing strong thermal stability at high temperatures. Besides, the porous structure of STA was beneficial for plugging through shape change and adsorbing water in drilling fluids. On the other hand, STA would interact with clay, increase the viscosity of the bentonite suspension to a certain extent, and improve the colloidal stability. Finally, STA plugged the pores and formed a thin, compact, and relatively hydrophobic filter cake, reducing fluid loss, even at high temperatures. STA can be used as a fluid loss additive with efficient high-temperature resistance and environmental friendliness and also provides new guidance for designing high-performance water-based drilling fluids.
