Embodiment Construction

[0071] The present invention will be described in detail below in conjunction with the accompanying drawings and experimental examples.

[0072] The purpose of the present invention is to provide a method for improving the storage efficiency of multi-azimuth stratum dip information on the premise of ensuring the accuracy of dip data. By this method, the access process of stratum dip information can be simplified, and the storage space of stratum dip data can be significantly reduced. Improve the efficiency of data transmission, data storage and retrieval.

[0073] The combined storage technology of multi-azimuth formation dip angle information in the present invention can accommodate different numbers of multi-azimuth formation dip angle data according to different storage accuracy. When the storage accuracy is 32 bits, if the formation dip accuracy of a single azimuth is 8 bits, it can store formation dips of 4 different azimuths; if the formation dip accuracy of a single azi...

Abstract

The invention relates to a seismic data storage technology, in particular to a method for improving storage efficiency of multi-azimuthal stratigraphic dip information. According to characteristics of the stratigraphic dip information, with byte as a unit, the multi-azimuthal stratigraphic dip information at one measuring point is compressed and stored in a combined way, so that the data storage space is significantly reduced on the premise of ensuring the dip data accuracy, the efficiencies of data transmission, data storage and data acquisition are improved, the storage and acquisition processes of the stratigraphic dip information are simplified, and a requirement on consistency of a two-dimensional seismic dip and a three-dimensional seismic dip is met.

Description

technical field [0001] The invention belongs to the field of petroleum and natural gas exploration and development, and relates to a seismic data storage technology, in particular to a method for improving the storage efficiency of multi-azimuth formation dip angle information. Background technique [0002] In the process of oil and gas exploration and development, seismic data interpretation is an important stage of seismic exploration engineering. This stage not only clarifies the underground structure characteristics for oil and gas exploration, but also provides favorable reservoirs for oil and gas exploration. [0003] Seismic data interpretation includes two important aspects: structure interpretation and reservoir interpretation. Whether it is structural interpretation or reservoir interpretation, stratigraphic dip analysis plays an irreplaceable role. [0004] According to the theory of seismic exploration, post-stack seismic reflection is equivalent to vertical in...
