Abstract

Abstract: During “13th Five-Year Plan” period, PetroChina formulated geophysical prospecting technology strategies for each basin and exploration domain according to their varying and increasingly complicated exploration and development objectives.Seismic acquisition design was a particular focus from the outset and process management was emphasized to ensure effective
deployment. Fine processing and interpretation of existing seismic data were conducted to exploit the full potential of data. Research was strengthened to improve problem-solving abilities and resolve bottleneck issues in production. Technical discussions
and workshops to address specific issues in individual basins and domains were encouraged, and training was given to interdisciplinary talents in geophysics and geology to enhance the overall quality of the talent team and the level of technological application.There was a strong focus on essential projects, and lean management was implemented to facilitate robust development. As a result, six categories of geophysical prospecting technologies have been developed and improved and nineteen key technologies formed to strongly support steady growth in oil production and rapid development of the natural gas business. In the “14th Five-Year Plan” period, the focus of petroleum exploration and development will shift to deep/ultra-deep formations, shale oil and gas, very complex surface areas, and more complicated domains. In addition, there will be technological challenges in improving the development of difficult-to-recover reserves and enhancing recovery in mature oilfields. To meet the demands of petroleum exploration development in the new environment, PetroChina will develop high-efficiency, low-cost, and high-precision geophysical technology at three levels—integrated promotion, scientific research, and experiments and pilot testing—in the eight key domains. Priority will be given to new generation geophysical prospecting technologies such as intelligent deep-layer geophysical prospecting technology, reservoir geophysics, and borehole seismic.
