AI Technical Summary

Technical Problem

Existing technologies suffer from insufficient resolution, reliance on insufficient well data, and difficulty in accurately depicting the spatial distribution characteristics of thin strata in complex geological regions when identifying and predicting deep and thin strata. This leads to discrepancies between the interpretation results and the actual geological conditions, affecting exploration and development and drilling tracking decisions.

Method used

A thin-layer stratum thickness prediction method based on genetic analysis is adopted. By analyzing the main controlling factors of stratum distribution, delineating tectonic boundaries, restoring stratigraphic geological models and iterative data models, and combining well inclination calculations, a stratum thickness prediction model is established. This reduces the dependence on seismic data and well network density, and uses sedimentological principles for quantitative prediction.

Benefits of technology

It improves the accuracy and reliability of thin-layer formation thickness prediction, reduces the requirements for seismic data quality, has a wider range of applications, can guide well location tracking and well location deployment, reduces calibration and rock physics analysis steps, and improves the simplicity and timeliness of operation.

Abstract

The application discloses a kind of based on genesis method's thin layer stratum thickness prediction method, system and medium, it is related to stratum thickness prediction technical field, the method includes: S10, stratum distribution main control factor analysis;S20, structural boundary delineation;S30, in combination with stratum distribution law and seismic delineation structural boundary, qualitative recovery is carried out to stratum geological model, obtains stratum thickness trend model;S40, in combination with stratum thickness data of drilled well and stratum thickness trend model, establishes stratum thickness prediction data model, and iteration is carried out to it;S50, according to well deviation of actual drilling, calculates the well bottom coordinate of the top of target layer;S60, calculates the key parameter of well bottom and coordinate boundary, then it is input into stratum thickness prediction data model, and stratum thickness is predicted.The present application introduces the principle of sedimentology, genesis method predicts stratum thickness, and is strong in logic, and the method is more reasonable;Meanwhile, the present application reduces the quality requirement of seismic data, and is strong in compatibility, avoids excessive processing of seismic data.
