Description

Technical Field

[0001] This invention belongs to the field of geological information processing technology and relates to a method for constructing reservoir models based on detailed analysis of fault segments. Background Technology

[0002] Large carbonate sedimentary layers were widely distributed during the Early Cambrian to Middle Ordovician periods. The long-term low geothermal environment provided hydrocarbon generation conditions for the Lower Cambrian source rocks. Combined with abundant mudstone in the Late Ordovician serving as reservoir-caprock, this formed a complete source-reservoir-caprock assemblage. Exploration over the past decade has shown that the Middle and Lower Ordovician carbonate rocks and Cambrian carbonate rocks are key areas for oil and gas exploration. Influenced by multiple tectonic movements, these areas have formed two main strike-slip faults and several secondary faults. In areas with distinct fault segments, the spatial distribution of "fault-controlled" fracture-cavity reservoirs is significantly constrained by fault zone boundaries. Creating geological models that meet the needs of reservoir description and reflect production dynamics and reservoir-permeability characteristics is of great significance for advancing reservoir development.

[0003] Chinese patent CN106570262B provides a method for describing reservoir configuration structure. Utilizing characteristic parameters of the target reservoir's configuration structure, it divides the reservoir configuration structure of all single wells within the target reservoir into multi-stage reservoir configuration structures. Based on the stable mudstone markers developed at the top of the target reservoir, it establishes reservoir connectivity relationships between the multi-stage reservoir structures of each well covering the target reservoir, quantitatively describing the characteristics of the target reservoir's configuration structure. This method offers high accuracy and has significant guiding significance for the refined development of oil reservoirs.

[0004] Chinese patent CN112814653A provides a method for determining the reservoir structure of fractured-vuggy oil reservoirs. This method establishes a water injection indicator curve relating injection pressure to cumulative injection volume, an energy indicator curve relating bottom hole pressure to cumulative production, a fluid level recovery curve relating static fluid level to time, and a well test indicator curve relating pressure to time. It also acquires the morphological characteristics of these curves and determines the reservoir structure based on these characteristics. This method can quickly and accurately determine the reservoir structure, thus providing important guidance for analyzing the causes of high-pressure water injection in fractured-vuggy oil reservoirs and developing high-pressure water injection technologies for these reservoirs.

[0005] Chinese patent CN115437013A provides a method, medium, and equipment for analyzing small-distance strike-slip faults in oil reservoirs. The method includes: identifying seismic attribute faults based on 3D seismic data to determine the macroscopic distribution and internal structural characteristics of strike-slip faults; interpreting seismic profiles to determine fault structural styles, combination characteristics, and spatial distribution patterns; visualizing the seismic profile interpretation results in 3D based on the fault structural styles, combination characteristics, and spatial distribution patterns; obtaining fault phase-based differential activity, fault zonal differential activity, and fault segment-based differential activity; establishing a 3D model of the strike-slip faults; and identifying favorable development zones of fault-controlled reservoirs based on the 3D model. This technology establishes a 3D model of strike-slip faults and identifies favorable development zones of fault-controlled reservoirs from the model, effectively avoiding the multiple interpretations and uncertainties in structural interpretation results, and possesses strong theoretical, practical, and operable characteristics.

[0006] However, existing technologies do not provide a method for studying reservoir structural characteristics and constructing related models based on fine analysis of reservoir segments. Summary of the Invention

[0007] In view of this, and addressing the problem that existing technologies cannot provide a better method for understanding reservoirs and their development characteristics, the purpose of this invention is to provide a reservoir model construction method based on fine analysis of fracture segments. This invention points out that the core main fractures in different segments have large incision depths, while the branches in pull-out segments have weaker incision depths. The compression segments have large incision depths, and the ends of these segments are affected by stress release or obstructed faulting, resulting in shallower incision depths and reduced fragmentation, with fracture characteristics being predominant. Reservoir development exhibits vertical stratification, with large-scale reservoirs mainly developing in shallow layers. Based on this, preliminary reservoir model construction has been carried out, which is beneficial for advancing reservoir description work.

Those skilled in the art can make various changes and modifications to the present invention based on the disclosed content, and such changes should also fall within the scope of protection claimed by the present invention.

[0052] Example 1

[0053] This embodiment provides a reservoir model construction method based on fracture segmentation and fine analysis. Based on geophysical data and single-well dynamic and static data, the fracture is segmented according to information such as fracture strength, reservoir differences and connectivity. On this basis, the reservoir characteristics within the segment are analyzed to study the "fault-reservoir" characteristics of the reservoir, and then a fault-controlled fracture-vuggy reservoir model is established to guide the construction of well networks in the development and deployment stage.

[0054] The specific implementation steps are as follows:

[0055] (1) Fault Segmentation Study. Under the constraint of the macroscopic laws of regional fault development, the continuity characteristics of regional faults (overlapping, bridging, and translational segments) are first analyzed based on the characteristics of various fault attributes such as coherence and ant bodies, as well as seismic time-migration profiles. On this basis, the seismic planar profiles of wells are analyzed, and the reservoir stress state, anomaly development scale, and fault penetration depth of actual drilled wells are statistically analyzed. According to the stress characteristics, the stress state of actual drilled wells can be divided into three types: compression, translation, and pull-apart. Based on the planar distribution characteristics of the three types of actual drilled wells and the continuity of regional faults, the inter-well connectivity is analyzed in combination with dynamic data such as inter-well interference testing, water and gas injection response, and tracer response characteristics. The fault zone is segmented (compression segment, pull-apart segment, and translational segment). The compression segment has a high activity intensity, and the breccia and fracture zones revealed by internal drilling have a significant advantage in both quantity and width, showing the characteristics of "multiple fracture zones + multiple fracture zones". The core structure of the pull-apart segment is mostly developed near the boundary section, and the internal core structure is underdeveloped. Its activity intensity is second only to the compression segment. The translational segment exhibits the weakest activity intensity among the three types of segments, with the core zone structure being the smallest in scale. It also has the fewest number of fracture zones controlled by a single cross-section, and the largest spacing between them. Based on this, through the analysis of continuous, equally spaced seismic profiles parallel to the fault strike and perpendicular to the fault strike, the static data characteristics of the fault, such as stress state, penetration depth, and degree of fragmentation, can be analyzed more specifically. (At the end of the segment, stress is released or obstructed, resulting in a shallower incision depth and a reduced degree of fragmentation, with fracture characteristics predominating. At different locations within the same segment, the main fault in the core has a larger incision depth and a higher degree of fragmentation, while the incision depth at the end is shallower and the degree of fragmentation is reduced.)

[0056] in, Figure 1 It reflects different segmentation characteristics. The main fracture in the core of different segments has a large incision depth, the branch incision depth of the tension segment is weak, and the incision depth of the compression segment is large. Figure 2 The characteristics of different segments are as follows: stress release or obstruction at the end of the segment leads to fracture, the depth of incision becomes shallower, the degree of fragmentation weakens, and the characteristics of cracks are predominant.

[0057] (2) Analysis of reservoir characteristics within segments. Controlled by faults, the reservoirs are most developed near the longitudinally penetrating faults in the middle of the segment, gradually becoming shallower towards both sides. The segment ends are dominated by fractured reservoirs, thus affecting the reservoir distribution characteristics within the segment. Seismic profiles were continuously extracted from the fault ends to the fault core within different segments. Combined with actual drilling data, well production characteristics, and relevant dynamic testing data, the characteristics of fault development and the degree of fragmentation were analyzed, and the reservoir development patterns were summarized. Taking the reservoir structure analysis of Shunbei No. 1 zone as an example, based on logging interpretation, well seismic calibration, and acoustic remote sensing data, the horizontal and vertical development characteristics of the reservoirs within different segments were analyzed. The No. 1 zone reservoir development exhibits vertical stratification; large-scale reservoirs are mainly developed in shallow layers, while deep reservoirs are limited in scale. The logging data of typical wells show obvious stratification, with active oil and gas in the shallow layers outside the faults and good logging data. Horizontally, the logging data calibration results of typical wells that penetrated the anomaly indicate that the reservoir has a core-zone structure characterized by overall fragmentation.

[0058] (3) Analysis of the "disruption-storage" characteristics of the storage group, such as Figure 3 As shown. Based on the analysis results of the reservoir characteristics within the segment, a "fault-reservoir" spatial structure model of Zone 1 was further constructed. The fault zone contains several cross sections, and each cross section consists of "strongly fractured bodies + weakly fractured cross sections." The fractured bodies exhibit two structures: overall fracture and asymmetric core zone. Overall fracture refers to overall fracture within the body, with a transverse net-to-gross ratio of 60-70%, a weighted porosity of 3-5%, and is common in reservoir sections above 8%, with a maximum of 20%; the radial flow section of the well test curve has a smooth morphology. The asymmetric core zone has a transverse net-to-gross ratio of 40-50%, a weighted porosity of 3-5%, and is rare in reservoir sections above 10%; the radial flow section of the well test curve shows a peak-like oscillation. It is clear that the strongly fractured bodies are the main reservoir space, while the weakly fractured cross sections (between longitudinal fractured bodies and weakly fractured cross sections) mainly develop fractures, exhibiting low reservoir capacity and high conductivity. The strongly fractured bodies are the main reservoir space on the fault zone, with permeability mainly distributed between 50-700 mD, increasing with depth. The longitudinally fractured body is characterized by a fracture zone, exhibiting low storage capacity and high conductivity. The weakly fractured section is also characterized by a fracture zone, with a porosity of 1.5-3.5%, possessing a certain storage capacity and high conductivity.

[0059] (4) Reservoir Model Construction. Based on the detailed research results of fracture segmentation, considering the "fault-reservoir" characteristics of the reservoir, the stress characteristics, structural fracturing degree, and seismic reflection characteristics of different parts of different segments are analyzed. Combined with field geological outcrops and well test data, an internal structural model of the fault-controlled fracture-vuggy reservoir is established. Figure 4 In the process, an overall fractured core zone structure model of the anomalous body near the main fault was formed, and an asymmetric core zone structure model of the main / passive disk was formed. A segmented reservoir model was formed with fractured bodies as the main storage space, fractures with low storage capacity / high conductivity, and fracture surfaces with high conductivity.
