Remote sensing based method for screening three-dimensional seismic receiving combination central point

Abstract

The invention provides a remote sensing based method for screening a three-dimensional seismic receiving combination central point. The method comprises the following steps: obtaining receiving goodness evaluation parameters according to an orthographic remote sensing image and a digital elevation model, determining the mandatory circumvent range according to the orthographic remote sensing image, wherein the receiving optimal evaluation parameters comprise high elevation, terrain slope and lithology classification; calculating theoretical receiving points according to seismic engineering acquisition parameters; determining whether the theoretical receiving points are enforceable receiving points or not according to the mandatory circumvent range; calculating the offset limiting parameters of the enforceable receiving points according to the seismic engineering acquisition parameters; determining whether a central point of a selectable receiving combination in the enforceable receiving points according to the offset limiting parameters; calculating the receiving goodness of the central point of the selectable receiving combination according to an optimized model corresponding to the receiving goodness evaluation parameters; calculating the combination expanding degree according to the combination area of the receiving combination and the most expanded area in proportion of combination elevation limit; screening the best receiving combination central point according to the receiving goodeness and the combination expanding degree.

Description

technical field [0001] The invention relates to the application technology of remote sensing in oil field seismic exploration, in particular to a method for screening the central point of three-dimensional seismic receiving combination based on remote sensing. Background technique [0002] In recent years, with the continuous improvement of the degree of oil and gas exploration, the fields and objects of oil and gas exploration have become more and more complex, seismic exploration has become more and more difficult, the risk has become higher, and the cost has also increased significantly. Especially in exploration areas with complex and varied topography (mountains, deserts, loess plateaus, etc.), it is more difficult to conduct 3D seismic exploration, data collection is difficult, signal-to-noise ratio is difficult to improve, and data quality is poor. Moreover, in high and steep mountainous 3D seismic exploration areas, the field of vision and implementation conditions a...

[0002] In recent years, with the continuous improvement of the degree of oil and gas exploration, the fields and objects of oil and gas exploration have become more and more complex, seismic exploration has become more and more difficult, the risk has become higher and higher, and the cost has also increased significantly

Especially in exploration areas with complex and varied topography (mountains, deserts, loess plateaus, etc.), it is more difficult to conduct 3D seismic exploration, data acquisition is difficult, signal-to-noise ratio is difficult to improve, and data quality is poor

In addition, in the 3D seismic exploration area of ​​high and steep mountains, it is more limited by the field of view and feasible conditions, and some seismic deployment schemes are not conducive to the selection of excitation and reception points.
