Situation and Prospects of Big Data Application on Drilling and Completion of Bohai Oilfield

Abstract

As a new field in petroleum engineering technology, Big Data and intelligent oilfields have garnered the attention and interest of the petroleum industry and researchers. Drilling and completion specialty in the Bohai oilfield have made significant data theory and technology attempts on the basis of establishing and improving data acquisition hardware, but it still needs to be improved and enriched urgently. Based on the investigation of the drilling and completion technology in the Bohai Sea, the progress of Big Data applications in drilling and completion is summarized. The WellView database, remote assistant decision-making system, cost fine management, and fracturing prediction based on Big Data are introduced. From the aspects of digitalization, intellectualization difficulty, and bottlenecks in technological development in drilling and completion in the Bohai oilfield, the challenges faced by Big Data and intellectualization are analyzed. From the aspects of national energy demand,guarantee of Big Data and intellectualized oilfield advanced technology, frontier interdisciplinary disciplines and foreign advanced experience, etc. The development prospects of Big Data and intelligent oilfields in the Bohai Oilfield are predicted, with a view toward promoting the rapid development of Big Data applications in drilling and completion.
