"The digital intelligence of reservoirs in Yangsanmu Oilfield has broken the space constraints, and now 100% of the project research can be completed online, and the efficiency of reservoir dynamic analysis has been increased by 35%." On May 13, in the digital intelligence reservoir demonstration area of Yangsanmu Oilfield, the sixth oil production plant of Dagang Oilfield, Ma Hanying, the person in charge, commented on the changes brought about by "digital intelligence".
Dagang Oilfield is a pilot enterprise for the digital transformation and intelligent development of PetroChina, and in the process of actively exploring the transformation method and path of "digital intelligence", it strives to build four goals: digital intelligent reservoir, digital intelligent wellbore, digital intelligent surface, and digital intelligent management. Based on this, the Yangsanmu Oilfield, which has a clear understanding of the reservoir and full coverage of the geological model, is selected as a demonstration area for the construction of digital and intelligent reservoirs.
After nearly 60 years of exploration and development, the Yangsanmu Oilfield as a whole has entered the stage of ultra-high water cut, and the remaining oil is highly dispersed. In the face of the relatively low efficiency of reservoir data processing, relying on the construction of digital intelligence reservoir V1.0, the dynamic and static multi-source heterogeneous data of reservoirs, wellbore, surface, drawings and geological models of 293 wells in Yangsanmu Oilfield were integrated, and a collaborative research platform integrating project library, graphic library and achievement library was created, which realized the visualization of reservoir information.
According to the reservoir research process, the data between stratigraphic comparison, seismic interpretation, geological modeling and numerical simulation research can be automatically matched with research resources, and the reservoir collaborative research environment of research data can be pushed on demand. Based on the results of the map, summarize the development and production data, customize and integrate the dynamic information of reservoir development and production, monitor the reservoir production dynamics in real time, and comprehensively and intuitively perceive the current status of reservoir development and production.
According to the relevant technical personnel, the integrated visualization of "points, lines, surfaces and volumes" of reservoir information has realized 100% centralized management of software and hardware resources, 100% online operation of research projects, 100% sharing and application of research results, and the intelligent level of reservoir research and development management has been greatly improved.
At present, Dagang Oilfield anchors the core business of reservoir research and management, continuously improves and establishes a standardized reservoir research and management template based on online synergy of reservoir research, online visualization of reservoir results, and real-time reservoir dynamic tracking, creating a digital and intelligent reservoir demonstration that can be promoted and replicated, and helping the old oilfield to continue to produce steadily.
