Background technology
For igneous reservoirs mainly based on crack elimination, the development degree in crack is often closely related with tomography.Igneous
Rock is influenced often to develop a large amount of tomographies by geological movement.Generally there are compared with strong reflection, top surface tomography is easier to know for igneous rock top surface
Not, but often it is mixed and disorderly reflection, while lack stable reference lamina greatly inside set igneous rock, interior fault is difficult to explain, to rear
Phase reservoir is implemented to make a big impact with oil reservoir development.We have invented a kind of new igneous rock interior fault explanation sides thus
Method solves more than technical problem.

Diagenesis top surface fracture system carries out meticulous depiction；Step 3, it is counter to push away interior fault position under the conditions of top surface fault interpretation is accurate
It puts；Step 4, the seismic properties of extraction reaction fault feature, correction interior fault position.
The purpose of the present invention can be also achieved by the following technical measures：
In step 1, the data collected is needed to include：Logging data, log data, geological layering data, poststack seismic data,
Establish seismic interpretation database.
In step 2, synthetic seismogram calibration is carried out, implements igneous rock top surface stratum reflectance signature；It is shaken and marked according to well
Determine result and explain igneous rock level by road, breakpoint is labeled as at igneous rock top surface reflection generation bad break, distortion, SPA sudden phase anomalies.
In step 3, dip slip is counted to every tomography equal interval sampling under the conditions of top surface fault interpretation is accurate
With vertical actual relative movement, computed tomography inclination angle；Top surface tomography is calculated in target according to target depth with stratigraphic dip according to tomography tendency
The amount of movement of depth forms preliminary interior fault plan view.
In step 4, the seismic properties of extraction reaction fault feature, including coherent body, ant body these seismic properties；It will
Top coat position is moved integrally to igneous rock inside story target depth, the seismic properties horizon slice of layer position after extraction is mobile；It will be preliminary
Obtained interior fault is with along layer seismic properties check analysis, being adjusted the position and combination of interior fault.
Igneous rock interior fault means of interpretation in the present invention, by using the relevant parameter of top surface tomography, exists to tomography
The position of igneous rock inside story is calculated, the interior fault of reckoning is corrected in conjunction with tomography relevant seismic properties.
The more accurate top surface fault information of igneous rock is utilized in this interior fault means of interpretation, avoids and lacks inner mark layer etc.
It explains difficult point, and realizes simplicity, for meticulous depiction igneous rock fracture system, it is great to carry out layer description research significance.
