Embodiment
For enable the present invention above and other objects, features and advantages become apparent, it is cited below particularly go out preferable implementation
Example, and coordinate shown in accompanying drawing, it is described in detail below.
As shown in figure 1, Fig. 1 is flow chart of the high sandy ground than turbidite layer description method of the present invention.
Step 101, fine synthesis record demarcation, the corresponding relation of lithology and Seismic reflection character is specified.In seismic work
Recorded and demarcated by fine synthesis in standing, specified the corresponding relation of lithology and Seismic reflection character, analyze high sandy ground and compare turbidite
Reservoir on common seismic section can descriptive probability.In one embodiment, the 3-D seismics where research area are in target zone
Section seismic data frequency band is narrow, and dominant frequency is low, and signal to noise ratio is low.The sand group turbidite sandy ground of this area's Dongying 4 is than high simultaneously, and nearly 50%,
From the point of view of fine synthesis record demarcation, sand body can not be retouched on seismic profile, and it is special that strong, weak axle can all represent lithologic sand body reflection
Sign, it is impossible to accurately portray sand body border, as shown in Figure 2.
Step 102, more well crossploting analysis, it is preferably able to the log of effective district sub-sand mud stone.Log is entered
Row normalized, by more well crossploting analysis, formation lithology change can be reflected than more sensitive log by finding out, such as
Natural potential, gamma ray curve.In one embodiment, unified correction and processing, including mud are carried out to log first
Rock baseline correction and normalized；By more well crossploting analysis, it is found that gamma ray curve is more sensitive to variation of lithological,
Sand shale can be preferably distinguished, as shown in Figure 3, Figure 4.
Step 103, the reservoir inversion under waveform instruction is carried out using effective log.Utilize the log preferably gone out
The reservoir inversion under Inversion Software progress waveform instruction is stepped by this.Its principle is to reflection system under seismic wave characteristic guidance
Array closes the process of optimizing, as shown in Figure 5.This method breaks through traditional limit of the wave impedance inversion based on spatial domain interpolation algorithm
System, not by well point distribution influence, using the phased inverting thought of waveform, variogram analysis reservoir is replaced using seismic wave characteristic
Space structure changes, and improves subtle hydrocarbon reservoir ability.In one embodiment, preferably gone out using step 102 to lithology sensitivity
Gamma ray curve steps the reservoir inversion under Inversion Software progress waveform instruction by this, and core is to be instructed in seismic wave characteristic
Under to reflectance factor combine optimizing process.Idiographic flow is as shown in Figure 6.
Step 104, from well, the well for participating in inverting is mutually compareed and carefully analyzed, determines inverting chromatographic zone
Block.The good effective sandstone of physical property is reflected with black and white.Finally utilize waveform similarity and inverting color change regularity extrapolation
Sand body border.In one embodiment, after step 103 inverting data volume tentatively generation, sand body description principle is formulated first.From well
Set out, the well for participating in inverting is mutually compareed and carefully analyzed, primarily determines that chromatogram block.Found by counting, shale
Content is proportionate with GR values, sandstone poor properties of the shale content more than 40%, is dried layer；In order to identify net sandstone,
Shale content is set to invalid sandstone (light gray, dark-grey) more than 40%, GR more than 100API；The good effective sandstone black of physical property and
White reflection, as shown in Figure 7.
Step 105, inverting well will be participated in and have neither part nor lot in the real sand body that bores of inverting well carry out contrast verification with inverting road by well,
Accurate tracking description is fully carried out to sand body with data such as inverting, drilling wells.In one embodiment, after the completion of step 104, cut
The inverting section of well was taken, the real sand body that bores for crossing well was contrasted with inverting road by well.From the point of view of contrasting, bore meet sand body with
Inverting section coincide preferable, and main oil-bearing sand bodies coincidence rate is high, and oil water relation not contradiction, the overall goodness of fit is more than 80%, such as
Shown in Fig. 8.From the point of view of effect, apparently higher than common seismic section, sand body pinching point is clear for the vertically and horizontally resolution ratio of inverting section,
Solve the problem that seismic profile can not carry out sand body description, using the invertomer, sand body is carried out with reference to data such as drilling wells accurate
Really tracking description.
