To address these issues, this study developed a high-performance composite gel material using a multi-component hybrid crosslinking strategy. The material employs \u03b3-methacryloxypropyltrimethoxysilane (MPTMS) as the silica source, which hydrolyzes in situ to generate SiO2, 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 \u00b0C 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\u201360 mesh, 20\u201340 mesh, and 10\u201320 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.<\/jats:p>","DOI":"10.3390\/gels12040325","type":"journal-article","created":{"date-parts":[[2026,4,13]],"date-time":"2026-04-13T08:49:02Z","timestamp":1776070142000},"page":"325","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Study on Synthesis and Performance of a Hybrid Crosslinked Composite Gel for High-Temperature Lost Circulation Control"],"prefix":"10.3390","volume":"12","author":[{"given":"Jiangang","family":"Shi","sequence":"first","affiliation":[{"name":"Oil Production Technology Research Institute of PetroChina Xinjiang Oilfield Company, Karamay 834000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuyang","family":"Yao","sequence":"additional","affiliation":[{"name":"Oil Production Technology Research Institute of PetroChina Xinjiang Oilfield Company, Karamay 834000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chaofei","family":"Wang","sequence":"additional","affiliation":[{"name":"Oil Production Technology Research Institute of PetroChina Xinjiang Oilfield Company, Karamay 834000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tao","family":"Ren","sequence":"additional","affiliation":[{"name":"Oil Production Technology Research Institute of PetroChina Xinjiang Oilfield Company, Karamay 834000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kecheng","family":"Liu","sequence":"additional","affiliation":[{"name":"Oil Production Technology Research Institute of PetroChina Xinjiang Oilfield Company, Karamay 834000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huijun","family":"Hao","sequence":"additional","affiliation":[{"name":"CNPC Engineering Technology R&D Company Limited, Beijing 102206, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhangkun","family":"Ren","sequence":"additional","affiliation":[{"name":"School of Petroleum Engineering, China University of Petroleum (East China), Qingdao 266580, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7678-9536","authenticated-orcid":false,"given":"Jingbin","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Petroleum Engineering, China University of Petroleum (East China), Qingdao 266580, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,11]]},"reference":[{"key":"ref_1","first-page":"215","article-title":"High temperature aging property evaluation of lost circulation materials in deep and ultra-deep well drilling","volume":"40","author":"Kang","year":"2019","journal-title":"Acta Pet.
