[Abstract]:In recent years, deep oil and gas exploration and development in China have been developing rapidly, while technological development has played a very important supporting role. In view of the complex engineering geological environment of deep oil and gas in China, the four major technological systems which have made great progress in recent years have been sorted out. Mainly including the deep complex structure seismic imaging and reservoir prediction technology system, including deep seismic "two width and one small" acquisition technology, inverse time migration processing technology, complex structure comprehensive modeling technology and variable velocity mapping technology. It improves the precision of structural interpretation, ensures the high precision imaging and prediction of deep geological bodies, and improves the drilling speed by a large margin. The drilling cost and drilling risk are reduced, and the deep high temperature and high pressure logging evaluation technology system is reduced, which provides a guarantee for the accurate identification of reservoir properties and fluid properties. In particular, the development and maturity of the technology of improving the volume of deep reservoir reconstruction improves the production rate of single well and the benefit of deep oil and gas development. Based on the analysis, the challenges faced by the exploration and development of deep oil and gas in the future are pointed out. In this paper, the key techniques of deep safe and efficient drilling and completion and control for deep layer seismic acquisition, processing and interpretation, namely, deep layer high temperature and high pressure logging evaluation technology, and deep layer oil and gas reservoir reconstruction, are discussed. This paper points out the future development direction of deep oil and gas exploration and development technology in four aspects of water plugging and lifting technology, and emphasizes that the development of applicability and economic technical system is the key to realize deep oil and gas efficiency and low cost exploration and development.
