[0066] According to the second embodiment of the method for rapid evaluation of deep-water channel reservoirs provided by the present invention, a fourth embodiment of the method for rapid evaluation of deep-water channel reservoirs is proposed. In the embodiment of the present invention, step S8 further includes:

[0067] If there is no mound-shaped bulge on the top boundary of the facies zone unit, it is determined that the facies zone unit is rich in mud and has no oil and gas exploration value.

[0068] In this embodiment, only based on the fact that the facies zone unit has no hill-shaped bulge, the area without oil and gas exploration value can be determined, and the large-area exploration area can be accurately excluded, so that the evaluation method of the deep sea channel reservoir is faster.

[0069] In an embodiment of the present invention, the step of determining the sand-rich degree according to the mound-shaped protrusions includes:

[0070] The bulge coefficien...

Abstract

The present invention provides a method, device and computer equipment for rapid evaluation of deep water channel reservoirs, which include: step S1, performing a layer pulling operation on a target channel deposition system along a regional marker layer; step S2, determining the target channel deposition system in the step S2. Bottom envelope interface; Step S3, determine whether there is a wedge-shaped natural bank top-bottom interface on the left and right wings of the bottom envelope interface; Step S4, divide the area to be evaluated into the bottom envelope interface and the wedge-shaped natural bank top-bottom interface respectively corresponding The natural embankment facies zone unit and the water channel filling facies zone unit; step S5, determine the sand-rich degree according to the mound-shaped protrusion. In the present invention, the evaluation method of determining the sand-rich degree by combining the layer pulling operation of the seismic data, judging the specific working conditions, dividing the facies zone units according to the corresponding working conditions, and determining the sand-rich degree in combination with the mound-shaped protrusions in the facies zone units, can be avoided. It is suitable for no-well / few-well conditions, and can also improve the evaluation accuracy of deep water channel reservoirs.

Description

technical field [0001] The invention belongs to the technical field of geological resources and geological engineering, and in particular relates to a method, device and computer equipment for rapid evaluation of deep water channel reservoirs. Background technique [0002] According to statistics, the remaining technically recoverable reserves of global marine deepwater oil and gas resources account for 43.7% of the world's remaining recoverable reserves, and it is the main battlefield for resource allocation of major oil companies. Deep water channels (channel sands) and terminal lobes (sheet sands) contain more than 90% of marine deepwater oil and gas reserves; among them, deep water channel reservoirs have continuously made major exploration discoveries in recent years, and are an important reservoir type for marine oil and gas exploration. Compared with onshore fluvial-delta sandbodies, deep-water channel reservoirs are more complex in terms of sedimentary composition, s...
