Laboratory simulation study on the preparation and maintenance of drilling fluid in the automatic drilling fluid preparation system

摘要:

自动制浆系统是一套集物料输送、精确计量、投放、动态混合、性能监测和自动控制等多种功能于一体的装备，该系统不仅可以降低配制钻井液劳动强度、缩短配制时间、提高作业效率，还能减少人工操作错误和干预、降低操作失误风险、提高钻进过程的稳定性和安全性。处理剂加量与性能间的关系是自动制浆系统控制运行的基础。本文围绕钻井液配方、性能维护和钻井液自适应调整，开展了一系列不同处理剂加量的室内模拟实验，建立一套钻井液性能动态调控模型，最终在自主研发的钻井液随钻在线自动配制系统上成功实现了上述功能的自动化运行。该研究结果对推动自动制浆系统向自动化全面发展有重要的实践意义。

Abstract:

The automatic drilling fluid preparation system is a set of equipment that integrates multiple functions such as material transportation， precise measurement， material feeding， mixing， performance monitoring and automatic control. It reduces labor intensity， shortens preparation time， improves work efficiency， reduces human operation errors， lowers the risk of mistakes， and contributes to improving stability and safety during drilling. The relationship between the dosage of treatment agents and the performance of drilling fluid is the basis for the control and operation of the automatic drilling fluid preparation system. In this study， centering on the drilling fluid formulation， performance maintenance， and self-adaptive adjustment of drilling fluid properties， laboratory simulation experiments with varying dosages of treatment agents were conducted. A set of dynamic regulation and control models for drilling fluid properties was established. Ultimately， the automated operation of the above-mentioned functions was successfully achieved on the self-developed online automatic preparation system for drilling fluid. The findings of this study hold great practical significance in facilitating the automation development of the automatic drilling fluid preparation system.
