Multi-functional nano-modified cementitious materials for well cementing

通过在油井水泥中加入不同的纳米材料，该项目旨在开发具有自感知特性的多功能胶凝材料，并在极端条件下（包括高/低温，高压和腐蚀性环境）具有更高的强度和耐久性。油井水泥的完整性和寿命对于石油和天然气资源的安全、高效、环境可持续生产至关重要。固井问题是导致威尔斯钻井和完井期间发生事故的主要因素，需要进行昂贵的补救。预计该项目开发的新型水泥将生产更安全的威尔斯井，同时减少（气体）环境排放风险。

By incorporating different nano-materials in well cements, this project aims to develop multi-functional cementitious materials with self-sensing properties and greater strength and durability under extreme conditions including high/low temperatures, high pressure and corrosive environments. The integrity and longevity of well cement are paramount for the safe, efficient, environmentally sustainable production of oil and natural gas resources. Cementing problems are the main factor contributing to incidents during drilling and completion of wells, necessitating costly remediation. It is expected that the novel cement developed in the project will produce safer wells with fewer (gas) environmental emission risks.
