Detailed description of the invention
The example that sequence 405 in Fig. 4 illustratively spherical model represents.Sequence 405 in side by sequence
Coboundary 410 demarcates, and demarcates by sequence lower boundary 415 at opposite side.
Sequence 405 includes three sub-sequences A, B and C.Each sublayer sequence is by complicated arc border boundary.
Sublayer sequence A is by lower boundary AL and high-rise border AU boundary.Sublayer sequence B by lower boundary BL (with height
Border AU is identical for layer) and high-rise boundary B U boundary.Sublayer sequence C by lower boundary CL (with high-rise border
BU is identical) and high-rise border CU boundary.
Sequence coboundary 410 and sequence lower boundary 415 both of which have plane of unconformity 420,425.The most whole
Conjunction face is erosion or the non-deposited surface that newer stratum and older rock stratum separate and represent notable interruption.
Three sub-sequences A, B and C terminate at plane of unconformity 420 on sequence coboundary 410, and under sequence
Terminating at plane of unconformity 425 on border 415, these planes of unconformity represent the geologic record on sequence either side
In disconnected ditch, as shown in Figure 5.These disconnected ditches represent and deposition wherein may occur and eat away subsequently or not
Disconnected ditch in the geologic record of deposition can occur.
Sequence 405 each several part can be used from top to bottom by the existing method of stratigraphic layering or from bottom to top
Stratigraphic layering, wherein top plane of unconformity 420 and basal unconformity face 425 are parallel to each other, and to layer
The other parts adoption rate layering of sequence 405.
Stratigraphic layering recover space-wise an embodiment in, sequence from the area shown in Fig. 4-
Deep space is converted into recovery space view.Such as, Fig. 6 illustrates that the sequence 405 from Fig. 4 is converted into favour
Strangling space, this is the example recovering space.The limit of interval A, B and C of complicated bend in the diagram
Boundary shows as horizontal line in figure 6.In Fig. 4, the disconnected ditch 605,610 in geologic record occurs in sequence
Either side.In one embodiment, can be by the ready-made instrument (OpendTect such as buied from dGB
Software) realize the conversion to wheeler space.
Equally, Fig. 7 illustrates the layer after having been converted into the pseudo-wheeler space as the example recovering space
Sequence.Pseudo-wheeler space has the profile of wheeler space but its vertical axis is the degree of depth rather than time.At pseudo-Wheeler
In space, segmentation plane of unconformity is to form disconnected ditch deposition no longer occur, the such as disconnected ditch 705 shown in Fig. 7
With 710, without being transformed into area-time territory.The pseudo-wheeler space of such as wheeler space is to recover space
One example, has wherein recovered the disconnected ditch (or missing part) in geologic record, and as the result (shape recovered
Become disconnected ditch), the top boundary of sequence and bottom boundaries (such as, are respectively top boundary 715 and the end of recovery sublayer sequence C
Border 720) it is almost parallel and level.In wheeler space, the top boundary of sequence and bottom boundaries are (such as,
It is respectively top boundary 615 and the bottom boundaries 620 of sublayer sequence C recovered) it is perfect parallel and level.One
In individual embodiment, can use and chart what branch company sold from the boundary mark of Halliburton companyInstrument realizes the conversion to pseudo-wheeler space.
In one embodiment, under the recovery space form of sequence, carry out stratigraphic layering, as shown in Figure 8,
Where the dotted line signifies that new Asia sublayer sequence (such as 810) between newly-increased border (such as 805).Perform each
The stratigraphic layering of the sublayer sequence recovered, is used for guiding the position of the bottom boundaries of its top boundary recovered and recovery
Put.Due to sub-sequence boundaries in pseudo-wheeler space almost parallel, proportional layered introducing therefore can be used new
Stratigraphic layering border.Layering from top to bottom and from bottom to top layering can also be used for many pseudo-wheeler space moulds
Type.Existing stratigraphic layering technology can also be used for using the stratigraphic layering of wheeler space model.At one
In embodiment, new border extends into disconnected ditch 605,610 or 705,710, simplifies existing stratigraphy further
The application of demixing technology.In one embodiment, new border does not extends into disconnected ditch 605,610 or 705,710.
In one embodiment, deposit deposition in time is modeled by space recovering.Such as,
Mass balance technology can be used.Quality (or area) across depositional sequence balances to relate to following the tracks of and passs in time
It is deposited on the volume of sediment (or area) of basin (basin) diverse location.Such as, mass balance analysis may
Attempt to follow the tracks of total deposit of either shallow deposition in time with the ratio of deep water environment.From utilize recover space or
Pseudo-wheeler space view, deposition the whole deposits corroded the most in time can be properly contained in quality
In EQUILIBRIUM CALCULATION FOR PROCESS.
In one embodiment, in recovering space, identify the ground phase boundray of each stratigraphic layering.Such as,
Such as porosity or resistive characteristic allocation are given sub-sublayer sequence or sub-sublayer sequence by the analysis permission of well logging daily record
A part.Distribute to the analysis of the feature of multiple sequences in model allow to identify ground phase boundray, such as sea
Border between rock and non-marial rocks.In one embodiment, by such as recovering in space shown in Fig. 8
The sign of sequence is converted back to traditional area-deep space, such as shown in Fig. 9.Note, in fig .9,
The new border being illustrated by the broken lines meets the sequence boundaries represented by solid line.
In practice, as shown in Figure 10, stratum, the space credit layer system of recovery is by creating and sequence pair
That answers recovers space and is operated in the sequence in conventional area-deep space (square frame 1005).Then system exists
Recover space sequence performs stratigraphic layering (square frame 1010).System is being recovered in space subsequently to deposit
The deposition passed in time is modeled (square frame 1015).Then system identifies the ground in the space sequence of recovery
Phase (square frame 1020).Then the space sequence of recovery is converted into traditional area-deep space (square frame by system
1025)。
In one embodiment, stratum, the space credit layer system of recovery is stored in the form of a computer program
On computer-readable medium 1105, such as CD or DVD shown in Figure 11.In one embodiment,
Computer 1110 reads computer program by input/output device 1115 from computer-readable medium 1105
And store it in memorizer 1120, if it is necessary, then by compiling with link is ready to carry out and subsequently
Perform.In one embodiment, system receives input also by the input/output device 1115 of such as keyboard
Output is provided by the input/output device 1115 of such as monitor or printer.In one embodiment,
The earth mould that system creates earth model in memorizer 1120 or amendment is present in memorizer 1120
Type.
In one embodiment, can be by obtaining resident to the network 1125 at long-range real-time operation center 1130
Earth model in memorizer 1120.In one embodiment, long-range real-time operation is centrally through network
1135 obtain earth model or the data from earth model, with at planning oil well 1140 or Drilling oil well
Help is made when 1140.
One or more specific embodiments of the present invention in broad meaning given above.Invention be also embodied in
In multiple alternate embodiment and be therefore not limited to those described herein embodiment.In order to solution is mediated a settlement description
And provide the description before present pre-ferred embodiments and be not intended to limit the present invention to disclosed essence
