Abstract

The invention discloses a method for carrying out fluid identification by using converted transverse wave earthquake data, which comprises the following steps: A, acquiring a slow transverse wave section according to the converted transverse wave earthquake data of a target storage layer; B, tracking and explaining the target storage layer according to the slow transverse wave section to acquire the amplitude of slow transverse wave; and C, carrying out the fluid identification for the target storage layer according to the amplitude of the slow transverse wave. The invention also discloses a device for carrying out the fluid identification by using the converted transverse wave earthquake data. The method and the device have the advantages that the method and the device can effectively forecast the distribution of oil, gas and water in sand shale oil-gas reservoirs according to the amplitude of the slow transverse wave.

Description

technical field

[0001] The invention belongs to the field of seismic data interpretation, in particular to a method and device for fluid identification using converted shear wave seismic data. Background technique

[0002] Converted shear wave seismic data come from multi-wave and multi-component seismic acquisition, which can be used to study the anisotropy of fractured oil and gas reservoirs and detect fracture development zones. When the shear wave enters the fracture, it splits into two mutually perpendicular waves due to the splitting of the shear wave. One wave propagates along the fracture with a faster speed and is called a fast wave; the other wave propagates perpendicular to the fracture with a slower speed and is called a slow wave. Therefore, information such as the width, density and direction of fractures can be delineated by using slow waves to provide better data for oilfield development.

[0003] But there is still a lack of similar research on continental ...
