FIG. 1 is a schematic diagram of a deposition sequence simulation flow in a sequence simulation system of a deposition basin according to an embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
For better understanding of the above technical solutions, the following detailed descriptions will be provided in conjunction with the drawings and the detailed description of the present invention.
Example (b):
referring to fig. 1, the invention relies on a Windows system to establish a sequence simulation system-ssms (sequential modeling system) which is composed of two subsystems of basin settlement process simulation and basin filling process simulation, and is a set of simulation system with strong comprehensiveness.
Simulating a forward model combining inverted settlement backsetting and basin formation in the sedimentation process of the basin; the basin filling simulation comprehensively considers factors such as basin sedimentation, gravity equilibrium effect, sea (lake) level lifting, sediment supply, erosion effect, sediment distribution, compaction and the like.
Fig. 1 shows a calculation flow of the SSMS simulation system. After the original form of the basin is set from the beginning, the simulation of each time interval is from 'determining the sediment supply amount' to 'compacting the sediment', and the simulated sequence stratigraphic structure and sedimentary facies distribution pattern can be obtained through n times of repetition according to the requirement of the geological model.
1. Structural settlement of basin
The determination of basin formation subsidence is one of the key issues in sequence stratigraphic simulation. The quantitative description can be generally carried out by a forward or inverse method. The inputs in the SSMS software we have created can be entered by the following methods: (1) applying a back stripping method to obtain a sedimentation rate as sedimentation input of sequence simulation; (2) calculating the settlement amount by using a proper theoretical model, and determining the settlement rate and the evolution of the basin by adopting a uniform instantaneous tensile model or a cantilever beam model and the like for the valley-cracked basin; (3) the settling rate and its variation are determined by the software user as desired.
2. Deposit compaction
The process of compaction of a deposit is influenced by factors such as lithology, settling rate, and fluid action. Lithology tends to play a dominant role. Under normal compaction conditions, it is generally assumed that the porosity of the deposit is exponentially related to depth (Athy, 1930; Allen P.A. and Allen J.R., 1992):
in the shallow part of the basin, the depth versus porosity relationship may be better calculated using the following formula (Falvey and middlleton, 1981):
wherein the content of the first and second substances,
is the porosity at a depth of y,
surface porosity and c compaction factor.
And c are primarily lithology related and can be determined by laboratory analysis and statistical analysis of known data. Setting the top and bottom depths of the deposited layer as Y2And Y1The depth of the top and bottom of the deposit at a certain depth of subsidence is S2 and S1, and the thickness of the deposit after compaction is given by the following formula (Allen p.a. and Allen j.r., 1992):
3. sediment load balanced settlement
Gravity-balanced settling of sediment must be considered in the basin filling simulation process. Assuming that the basin structure settles to Y (water filling), water in the basin is replaced by sediment and then settles to S, considering only local or Airy equilibrium (turcote and acraham, 1977), there are:
where Y is the structural settlement, ρm、ρs、ρwRespectively, mantle, sediment and water density. If flexural balance is considered, the flexural settlement w (x) caused by the load l (x) can be expressed (without considering the horizontal stress):
wherein the content of the first and second substances,
the flexural rigidity depends mainly on the effective elastic thickness (Te). When the basin is wide or the effective elastic thickness is small, the flexural balance approaches local balance.
4. Geometry of the deposition sequence
The technical routes and methods of basin filling simulation are numerous, the choice of which depends on the purpose, scale and object of the simulation. The simulation of the process of carrying, dispersing and stacking the sediments by focusing on research is often described by a hydrodynamic method; the simulation for the purpose of analyzing the geometrical relationship between the macroscopic process and the deposition sequence is often described by a geometrical method. The SSMS simulation software established in the research mainly aims at simulating the geometrical morphology and distribution of a deposition system.
(1) Geometry and deposition uniformity of chip deposition sequence
The chip deposition sequence and the shape and distribution of the deposited body are the comprehensive results of various deposition operations and structural actions before the deposit is carried, accumulated and reconstructed until the deposit is buried. We do not care about the specific processes of these effects and focus on the overall results of these effects, i.e. the sequence of the deposited layers and the external morphology and internal composition characteristics of the deposited body, which are produced by their interaction over a period of time. Under conditions of equilibrium, the depositional geometry and the overall lithofacies pattern may be generally described by a so-called "depositional equilibrium surface".
The concept of a sedimentary equilibrium surface has long been known, and Powell proposed the existence of an equilibrium interface, called a sedimentary level, under the river as early as 1875. But the systematic application of the concept to the analysis of the geometry of the sediment body is started after the occurrence of the stratigraphy of the sequence. The sedimentation equilibrium surface is actually a state where the basin kinetic energy condition and the sedimentation topography reach equilibrium. The rise or fall of the equilibrium surface is directly related to the change in the deposition reference surface. The sedimentation equilibrium surface from the terrestrial environment to the marine environment has a certain variation trend, and is related to the energy of different parts of the sedimentation basin. In a two-dimensional cross-section, it is generally represented by the slope of the deposition surface. The determination of the sedimentary equilibrium surface can be determined by analysis (to debulk and eliminate the influence of the structure) according to the observation result of the modern environment by the predecessor and the combination of the sedimentary morphology displayed by the seismic section. Cant et al applied this concept to perform detailed geometric analyses of the depositional sequence, sequence interfaces, and distribution of depositional phases.
In modeling, different depositional or dephasic domains (depositional or facies tracks) may be represented by different depositional slopes or curves. The deposition always occurs from strong to weak, and the corresponding deposition equilibrium surface (slope) gradually becomes steeper and steeper.
For example, from the alluvial fan to the river plains, from the shore zone or the delta leading edge to the far shore zone, and from the continental slope to the deep sea plains, all have the variation trends that the deposition kinetic energy is from strong to weak, and the deposition equilibrium surface is gradually reduced from steep. Generally, the decrease in deposition rate at the distal end of the debris deposition system can be considered to be exponentially decreasing. For simplicity, the depositional ramp for each depositional domain may be given by:
(x) Ax + B when a < x ≦ B (proximal) (6)
f(x)＝T0e-cxWhen b is<x is less than or equal to c (far end) (7)
A, B, T therein0A, c define a deposition domain that is constant. In a two-dimensional cross-section, the lateral area side of the deposition sequence can be represented as:
wherein the amount of sediment supplied from outside the basin to inside the basin is SI, the corresponding amount of sediment accumulated in the basin is DS, ff (x) is a function describing the cross section of the deposition sequence, which is defined by the top and bottom interfaces (sediment equilibrium surfaces) of the deposition sequence.
(2) Sedimentary sequence of carbonate rock
In the carbonate deposition area lacking in the terrestrial debris, the deposition rate of carbonate is closely related to the growth rate of photosynthesis and organisms. The organisms breed massively in a shallow water light zone smaller than 6-8m, the deposition rate of the carbonate rock is high, and the growth rate of the carbonate rock is reduced rapidly along with the increase of the depth. The carbonate deposition rate can be expressed as a function of water depth. On a macroscopic scale, the relationship can be applied to simulate the relationship between the geometrical morphology of the carbonate sedimentary horizon and the structure settlement and sea level lifting. Assuming that the deposition rate of carbonate is ff (v), the deposition time is t, and the deposition thickness h is given by:
5. variation of deposition reference plane
In the marine basin, the variations in sea level are considered to substantially coincide with the variations in the sedimentary datum. In the lake basin, the lake plane represents a local deposition reference plane of the lake basin. The variation of the deposition reference surface is controlled by a number of factors and often shows different levels of variation, which can be reflected by the superposition of sinusoidal functions of different amplitudes:
6. analysis of simulation examples
Relatively stable coastal facies deposits often develop at the edge of discrete continents or at the post-fissure stage of the riflescent basin. In these zones, fluctuations in sea level may be a major factor controlling the development of rank 3-4 sequences. Research shows that under the condition of unchanged or little change of the set sediment supply rate and the set sedimentation rate, two classical sequence interfaces and sequence types, namely type I and type II, can be simulated by using SSMS through changing the sea level height. Layer sequence boundaries of type i can be achieved by setting a rapid sea level drop. The sea level needs to be lowered below the break point. Deposition occurs only on the side of the slope toward the sea. The layer sequence interface II is formed when the sea level is kept unchanged or descends, but is higher than the slope break point. The use and function of the SSMS simulation system are illustrated below by the example of simulated analysis of the development process of the sequence at the late stage of the pot fissure at the edge of the discrete continent.
Basin settlement is associated with thermal decay at the post-fissure stage of discrete continent edges or rift valley basins, with the rate of settlement decaying exponentially over time. Section one set the sedimentation rate decays from 65m/Ma at the beginning to 20-25m/Ma after 25 Ma. The sea level changes in a symmetrical Sin period, and the lifting amplitude is +/-200 m. The land of the sedimentary slope (balance surface) is 0.07, the coastal plain is 0.005, the shoal sea is 0.04, the maximum depth is 250m, the continental slope is 0.08, and the maximum depth is 1200 m. At the same time, it is assumed that there is sufficient time for the sedimentation or erosion to reach equilibrium when the sea level is rising or falling. The simulation gives the relative sea level and its relationship to the sedimentary system domain superimposed by the tectonic settlement and sea level variations. It can be seen that the three sea level low stage erosion surfaces form three sequence interfaces. The top of the high water level system area is obviously eroded (the erosion reaches an equilibrium state), and the low water level area and the water inlet system area are well preserved. The sequence of early development is in the early stage of thermal decay sedimentation, the sedimentation rate is high, and a system domain with overall rapid water inflow is formed. Three phylogenetic domains in the middle part of the sequence are completely developed. The sedimentation center migrates toward the basin due to the gradual decrease in sedimentation rate.
In order to analyze the influence of the construction settlement rate and the sea level lifting amplitude on the sequence structure and the sequence (interface) type, the construction settlement rate and the sea level lifting amplitude can be respectively changed to carry out simulation experiments.
When the lifting amplitude of the sea level is increased from +/-200 m to +/-250 m, the lifting amplitude of the sea level is increased, so that the deposition system is obviously propelled towards the sea direction when the sea level descends, and the development of a low-level region and the formation of an I-type sequence are facilitated; when the sea level rises, the deposition system obviously retreats towards the land direction, and the deposition system migrates for a long distance to form a deposition sequence structure with obvious sea advance and sea retreat, which is obviously different from the section I.
The sedimentation rate was reduced from the first 120m/Ma to 20-25m/Ma, the other conditions being in accordance with the simulation conditions of section one. The rapid settlement results in a large rise relative to sea level, and the slope forms a deepwater basin. The developing sequence is mainly the type II sequence, the development border system domain and the hypo system domain are poor or not developed.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
