摘要: 深水 表层导管喷射安装是海洋油气开发的关键环节,其作业时效与井口稳定性直接制约着深水建井的工程周期与经济成本。导管喷射安装时间由喷射钻进时间和静置恢复时间两部分组成,二者受多种喷射参数的共同影响,其复杂性及相互制约关系使得传统优化方法难以实现。采用正交模拟实验数据,同时考虑喷射钻进与静置两阶段时间的复杂关联,以及不同地层和操作参数之间的非线性影响,开发出并行预测喷射钻进时间与静置恢复时间的多输出预测模型。通过转化所建立的多输出预测模型,设计基于树结构Parzen估计器与高斯过程相结合的分阶段贝叶斯优化方法应用于综合目标优化,进而调整优化目标权重系数,揭示出优化参数在不同时间阶段效率提升上的关键作用。以深度分别为70 m、80 m、90 m的目标井为案例进行了实证分析。建立了最优的喷射钻井参数组合,新方法较常规设计方法喷射钻进时间平均增加了2.91 %,静置恢复时间平均减少了14.98 %,总作业安装时间减少了6.8 % 。通过量化多维参数间的非线性制约关系,实现了作业时效与井口稳定性的全局协同优化,为喷射参数精细化决策提供了算法指导。

Abstract: T he jetting installation of deepwater surface conductors is a pivotal process in offshore oil and gas development. Its operational efficiency and wellhead stability directly influence the engineering timeline and economic costs associated with deepwater well construction. The total installation time is comprised of two phases:jetting drilling time and shut-in time. Both phases are influenced by a range of jetting parameters. Due to the complexity and interdependencies among these parameters ose significant challenges for conventional optimization methods in achieving satisfactory solutions. This study employs data from orthogonal simulation experiments, taking into account the intricate relationships between jetting drilling time and shut-in time, as well as nonlinear interactions among distinct geological formations and operational parameters. On this basis, a multi-output predictive model was developed to simultaneously forecast both jetting drilling time and shut-in time. Building upon this model, a staged Bayesian optimization method was devised, integrating the Tree-structured Parzen Estimator with Gaussian Processes for comprehensive objective optimization. By adjusting the weight coefficients of the optimization targets, this approach reveals the critical role of optimization parameters in improving efficiency at different stages of the process. Empirical analysis was conducted on target wells with depths of 70 m, 80 m, and 90 m. An optimal combination of jetting parameters was identified, resulting in a 2.91 % increase in jetting drilling time on average, compared to conventional design methods. However, the shut-in time was reduced by 14.98 %, leading to a 6.8 % reduction in total installation time. By quantifying the nonlinear interdependencies among multi-dimensional parameters, this research achieves a global collaborative optimization of operational efficiency and wellhead stability. This approach offers algorithmic guidance for the refined decision-making of jetting parameters.
