本文所选的主题是MPD(管理压力钻井)自动化。该系统在井下压力系统中具有准确和精确的控制。今天的MPD系统不仅可以操作更紧凑的操作，更重要的是，它们可以在钻井过程中提供动态实时控制。这种精确的精确度使得人们可以直接接触到那些在前几次被认为不可钻探的资产(Breyholtz,Nygaard和Siahaan 2010)。MPD的自动化使得这一过程有了这样的成功。自动化有助于提供功能控制级别，这对手动操作人员获取和支持是有问题的。与传统自然方法一样，封闭循环的固有模式有向MPD中应用自动化的趋势(Breyholtz et al. 2010)。即使在过去几年中所有的MPD自动化改进之后，仍然存在一个普遍的错误观念，即MPD的现有系统能够在整个钻井过程中完全控制自动化。这篇文献综述以最好的方式阐述了这一过程，概述了在自动化领域中从这方面获得的所有有利的教训和成功。
The topic which has been selected for the purpose of this literature review is MPD (Managed pressure drilling) automation. This system has resulted in heralding accurate and precise control of downhole pressure system. The MPD systems of today can not only operate in tighter envelopes of operations but more essentially, they can provide well control with dynamic real time when drilling has been undergoing. The precision dynamically has allowed access of direct nature towards the assets which were considered not drillable virtually in the previous times (Breyholtz, Nygaard and Siahaan 2010). Automation in MPD has allowed the process to boast this type of success. Automation helps in providing functional control levels which are problematic for manual operators to gain and sustain. The inherent set up with closed looping along with methodology of conventional nature has a tendency to lend towards applications of automation within MPD (Breyholtz et al. 2010). Even after all the MPD automation advancements taken place in the previous few years, there exists a common wrong conception that present systems of MPD have the ability of providing full control of automation for the entire process of drilling. This literature review addresses this process in the best possible manner by outlining all the favourable lessons learnt and successes gained from this regard within the automation field.
