Abstract

The invention discloses a three-phase coupling reservoir configuration depicting technical method. The method comprises the steps of establishing a rock core-configuration phase, establishing a well logging-configuration phase, establishing an earthquake-configuration phase and representing and verifying a three-phase coupling reservoir configuration. The beneficial effects of the invention are that: in the step D of representing and verifying the three-phase coupling reservoir configuration, the research results of the first three steps are integrated in the step, single-well configuration discrimination of the non-cored well is realized on the basis of a rock core-configuration phase; a spatial configuration superposition mode of the logging-configuration phase is established on the basis of the rock core-configuration phase; a logging-configuration phase constrained seismic-configuration phase established by using methods such as attribute clustering and seismic waveform indicationinversion is used as a depiction representation basis to achieve spatial depiction of configuration distribution; and contradictions are repeatedly demonstrated and eliminated from a one-dimensional single well to a two-dimensional plane and from a profile to a three-dimensional space, final reservoir configuration space distribution characteristics are defined, and a reservoir configuration characterization result is verified through dynamic data to complete reservoir configuration description and verification.

Description

technical field [0001] The invention relates to a reservoir configuration characterization technique, in particular to a "three-phase coupling" reservoir configuration characterization technique, which belongs to the technical field of reservoir configuration research. Background technique [0002] Reservoir architecture research is an important basic work in high-precision reservoir description reconstruction subsurface cognition system. There are many basic data used to study and characterize the reservoir architecture. At present, most of the reservoir architecture studies are characterized by a single method for reference to the research methods of sedimentary facies. Reservoir architecture research has its own characteristics: when studying reservoir architecture, different research data and methods need to be selected according to different levels, and different data have their own limitations. Applying a single method with a single data can only be used for a certain ...
