Plain-English summary
This study looked at a new type of gel designed to stop fluid loss in high-temperature environments, which is a common problem with traditional materials. The researchers created a composite gel that combines different materials to improve its strength and stability when exposed to heat. They used a special silica source that helps the gel resist high temperatures, along with other components that make it tougher and more effective. Tests showed that this new gel can successfully seal off areas where fluids might escape, even in very hot conditions. Overall, the new gel performed well and met the necessary engineering standards for use in challenging environments.
Abstract
Conventional chemical gel plugging materials often suffer from poor high-temperature stability and inadequate mechanical properties. To address these issues, this study developed a high-performance composite gel material using a multi-component hybrid crosslinking strategy. The material employs γ-methacryloxypropyltrimethoxysilane (MPTMS) as the silica source, which hydrolyzes in situ to generate SiO<sub>2</sub>, thereby enhancing temperature resistance. Laponite nanoplatelets are incorporated as a toughening agent and physical crosslinking points, while a self-synthesized reactive microgel (BWL) serves as the organic crosslinking core. Through copolymerization with monomers such as acrylamide (AM) and methacrylic acid (MAA), a triple-crosslinked network structure is constructed. Compared with conventional gels, the synthesized hybrid crosslinked composite gel maintains a high storage modulus and loss modulus after aging at 140 °C and exhibits excellent tensile and compressive properties. Furthermore, the gel was processed into particle-based lost circulation materials with different particle sizes. High-temperature and high-pressure plugging experiments demonstrate that when using a mixed system of 40-60 mesh, 20-40 mesh, and 10-20 mesh gel particles with a total concentration of 2%, it can effectively seal highly permeable sand beds and fractures with apertures up to 5 mm. This meets the engineering requirements for lost circulation materials with high strength and high stability in deep, high-temperature formations.
