3 Terms and Definitions
For the purposes of this document, the terms and definitions given in GB/T 8423.1 and the following apply.
3.1
carbonate
A sedimentary rock primarily composed of authigenic carbonate minerals such as calcite and dolomite.
3.2
carbonate reservoir
A reservoir formed by the accumulation of petroleum in a carbonate (3.1) reservoir trap.
3.3
oil layer group
A combination of oil layers deposited continuously under similar sedimentary environments, characterized by similar distribution, lithological properties, electrical characteristics, physical properties, and fluid properties, with stable and relatively thick interlayers at the top and bottom.
[SOURCE: GB/T 8423.1-2018, 4.1.2]
3.4
fracture-cavity unit
A flow unit composed of one or several caves and vugs connected by a fracture network, possessing a unified pressure system, or a fracture-cavity reservoir body that relatively independently controls oil and water movement.
Note: The fracture-cavity unit is the basic unit for estimating recoverable geological reserves.
3.5
united fracture-cavity system
A concentrated development area of fracture-cavity reservoirs controlled by the same karst development background (structure, faulting, geomorphology, drainage system, sedimentary facies belt), composed of one or more related fracture-cavity units (3.4).
Note: The fracture-cavity system is the basic unit for estimating proved geological reserves.
4 Stage Division and Tasks of Reservoir Description
Shall be implemented according to the provisions of SY/T 5579.1.
5 Basic Data and Quality Control for Reservoir Description
5.1 Basic Data
5.1.1 Geological Data
Shall be implemented according to the provisions of SY/T 5579.1.
5.1.2 Seismic Data
Shall be implemented according to the provisions of SY/T 5579.1. For fractured-vuggy and fractured reservoirs, broadband, wide-azimuth, and high-fold seismic data volumes should be used.
5.1.3 Logging Data
Shall be implemented according to the provisions of SY/T 5579.1.
5.1.4 Well Logging Data
Shall be implemented according to the provisions of SY/T 5579.1. Additionally, the logging suite should be optimized. Combined logging should include curves such as natural gamma ray, dual caliper, laterolog, acoustic interval transit time, compensated neutron, and density. Appropriate wells should be selected for electrical imaging logging, elemental logging, natural gamma ray spectroscopy logging, and nuclear magnetic resonance logging.
5.1.5 Well Test, Production Test, Injection Test, and Well Testing Data
Shall be implemented according to the provisions of SY/T 5579.1.
5.1.6 Production Performance Data
Shall be implemented according to the provisions of SY/T 5579.1.
5.1.7 Dynamic Monitoring Data
Shall be implemented according to the provisions of SY/T 5579.1.
5.2 Quality Control
Shall be implemented according to the provisions of SY/T 5579.1.
6 Main Contents of Reservoir Description
6.1 Description of Regional Geological Characteristics
Utilize research results from the exploration and evaluation stages to describe regional geological characteristics, including the regional tectonic location, structural setting, sedimentary environment, karst environment, reservoir-forming conditions, and characteristics of strata encountered by drilling.
6.2 Stratigraphic Division and Correlation
6.2.1 Regional Stratigraphic Division and Correlation
Compile a comprehensive stratigraphic columnar section using seismic and well logging data, and relevant data on lithology and assemblage characteristics, paleontology, and isotopes. Conduct regional stratigraphic correlation, establish a standard correlation profile and an isochronous stratigraphic framework, and compile a stratigraphic layering data table.
6.2.2 Fine Stratigraphic Division and Correlation
