Well Integrity Canada 2030

油井泄漏是加拿大的一个主要问题，无论是石油渗漏还是温室气体（GHG）的释放。泄漏的发生是因为油井没有有效地胶结。改进这一过程的困难有三个方面。(i)在固井过程中几乎无法测量流体的实际投放情况。（ii）对于陆上井来说，在下井后直接评价水泥质量是不常见的。这方面的日志记录方法也不精确。（iii）监管机构和生产商目前的操作方式是被动的，即对泄漏。在这个项目中，研究人员将开发固井过程的预测模型和模拟。他们将与加拿大领先的服务公司和广泛的利益相关者指导委员会合作，以确保适用性。在开发了能够进行物理预测和改进设计的工程工具后，设计工具将免费分发给加拿大的利益相关者，并以其他研究小组可以为未来的开发和使用做出贡献的方式进行组织。这将为理解固井过程建立一个共同的基线，并允许知识和设计实践的共同进步。

Well leakage is a major concern in Canada, both in terms of oil seepage and release of greenhouse gases (GHG). Leakage occurs because the wells are not effectively cemented. The difficulty in improving this process is threefold. (i) Very little can be measured during the cementing process, concerning actual placement of fluids. (ii) For onshore wells it is not common to evaluate the cement quality directly, after placement. Logging methods for this are also not precise. (iii) regulatory bodies and producers currently operate in a way that is reactive, i.e. to leakage. In this project the researchers will develop predictive models and simulations of the cementing process. They will do this in collaboration with leading Canadian service companies and with a broad steering committee of stakeholders, to ensure applicability. Having developed engineering tools that enable physical prediction and improved designs, the design tools will be distributed freely to Canadian stakeholders and structured in such a way that other research groups can contribute to future development as well as usage. This will establish a common baseline for understanding of cementing processes and allow communal advances in knowledge and design practices.
