The data processing of natural gas exploration enters "the Cloud age"

Now, whether it is in the vast expanse of the desert in Xinjiang, or in the mountains of Southwest Mountain, the Oil Geophysical Research Institute of the first line of technical service personnel only with a laptop or mobile phone, you can login cloud computing platform to share data, access to a large number of technical resources to support, faster, To carry out the prophase processing of the field seismic data accurately.

After more than two years of development and operation, the largest geophysical cloud computing center built by the Institute has become an important support for the efficient development of oil and gas. "The completion of the Geophysical Cloud Computing Center has not only built a platform for data sharing and technology integration, but has also created an enabling environment for speeding up the application of scientific research," said Chushouli, dean of the Academy. This is of great significance for realizing the upgrading of scientific and technological innovation by informatization and improving oil and gas exploration efficiency. ”

Total computing Capacity (single precision) 2248 trillion times/sec, the total reserves of resources 3500TB, the annual processing of a variety of seismic data nearly 20,000 square kilometers.

As the "Vanguard force" of oil and gas exploration and development, an important mission of geophysical prospecting is to calculate and deal with the exploration data, and to provide the basis for the exploration decision-making for the clear understanding of the underground geologic structure and the accurate delineation of the location of the hydrocarbon strata. With the rapid development of oil and gas exploration in recent years, the data of original seismic detection have been increased. How to complete a large number of exploration data analysis and processing in a short time, exploration industry, "the pressure of Alexander."

To meet the challenge from big data, to meet the requirements of the increasing seismic data processing for computing and storage capabilities, the Geophysical Institute builds a cloud computing center based on the High-performance computer Group and Information Network system, greatly enhancing computing power and data processing capabilities, shortening the production cycle and leading the exploration data into the "cloud era". The hospital deputy Dean, chief Engineer Zhao improve the introduction, the current Institute of Cloud Computing Center total computing Capacity (single precision) has reached 2248 trillion times/sec, the total resource storage capacity reached 3500TB, can be cumulative to provide about 78 million CPU (core) hours, 698.86 million GPU (core) hours of high-performance computing services, Annual processing of various seismic data of nearly 20,000 square kilometers.

In order to improve the practical application ability, the institute in the Cloud Computing center has deployed some advanced mainstream applications and self-developed Icluster seismic imaging System, news integrated interpretation system and other software products, supporting the geophysical technology research and development, production demonstration and application business, It can provide more powerful technical support for the exploration and Development hotspot area of Sinopec at home and abroad.

Promote the cooperation of various professional plates, joint combat, quick results

The operation of Cloud computing center directly leads to profound changes in scientific research methods.

Now, the Institute is making great use of cloud computing center integration of the abundant resources to organize project development. With its powerful functions, researchers have freed themselves from the constraints of computational resources and limited software applications, and have been able to acquire technical information, share data, obtain resource support, accelerate the process of technological innovation and promote the efficient development of the project.

"As the cloud runs, it feels like a supermarket, and you can get a lot of technical resources at all times, as needed." Moreover, it has been better to achieve the cooperation between the various professional plates, joint operations, to promote early results, fast results. The researchers said.

High-efficiency green and high level operation and maintenance simultaneously

Strengthening the efficient management of cloud computing has been the goal of the Institute. They are integrated in the overall design of the cloud computing management platform, the key technologies, such as the development and deployment of the main functional modules, have realized the functions of user unified management, Environment monitoring, resource management and dispatching, cloud security operation and maintenance, remote application, etc., and have established the remote office environment for researchers to interact with each other. Effectively support the development of scientific research and production work.

In order to realize the green operation of Cloud computing center, according to the actual situation of high performance computer group consuming energy, through independent research, the cold channel closed refrigeration technology was implemented comprehensively, and the energy consumption of room was decreased significantly. Now, they are trying to use high-voltage DC power technology, is expected to save energy efficiency of more than 30%.

In addition to doing a good job of energy saving, strengthening monitoring and management, to achieve a high level of operation and maintenance is another focus of the institute's Cloud Computing Center. At present, the center has achieved system monitoring, network monitoring, site monitoring and so on, through weekly, monthly and annual reports and other means of monitoring the results of regular analysis, in order to make more accurate decisions to provide a reliable basis.

Chushouli said: "The completion of the Geophysical Cloud Computing Center, adapting to the rapid development of information technology and scientific and technological innovation in the era of demand, will certainly become the backbone of oil and gas exploration and development." We will further strengthen the cloud computing center capacity-building, optimize technical measures to promote the full application of the group to support the upstream plate efficient development play a more prominent role. ”
