Intelligent Pressure Control System on Drilling Process

摘要

MPD (managed pressure drilling) is an important technique for challenging drilling operations especially in narrow operational windows, the IPC (Intelligent Pressure Control) system is equipped with the ultra-compact MPD manifold (L3.6m*W2.3m*H2.8m) with complete functionality of measurement & automatic control system, benefit the operators on footprint reducing for limited field space especially offshore operations. The 3D interface of IPC software provides operator with a perceptual intuition about current status of the equipment. IPC system doesn't rely on PWD sensor to acquire the downhole pressure data, with the unique algorithm integrated in iPWD module, the real time downhole pressure data could be generated without any downhole PWD sensor, the deviation between iPWD data and real PWD data is within 3%, which was proven in over 40 wells operation. Nebula system is an add-on feature for IPC system, using cloud and IoT (Internet of Things) technologies, the Nebula could track the equipment's specific location, working status and drilling parameter, providing statistical diagnosis based on data collected from field operations, which helps operators to make decisions quickly. The data uploaded to cloud could generate different reports according to end user's requirements, to analyze drilling operation challenges or difficulties, this could be an intelligent tool which helps operators learn and understand the features of different blocks smarter via big data analysis. You can receive all data provided by Nebula system on your cellphone and PC at any time anywhere once connected to cloud station, always keep an eye on field operation and get the latest drilling parameters.
