摘要? 目前,,尚未存在全面的斷控巖溶型溶洞訓練數(shù)據(jù)集用于深度學習建模,。本文采用基于露頭資料、地震數(shù)據(jù),、可靠的地質模型以及基于目標的方法研制了斷控巖溶型溶洞原型模型,,對不同來源的原型模型集進行組合、旋轉,、裁剪和優(yōu)選操作來構建可靠且多樣的斷控巖溶型溶洞相訓練數(shù)據(jù)集,,同時構建相應的虛擬井和概率體訓練數(shù)據(jù)集,,作為訓練條件化生成對抗網(wǎng)絡的數(shù)據(jù)輸入。將訓練好的生成器卷積神經(jīng)網(wǎng)絡應用于塔河油田TH12330 井區(qū),,生成的多個斷控巖溶型溶洞地質模型符合地質模式,,吻合條件井、概率體數(shù)據(jù),,且與構造,、裂縫和累產(chǎn)基本一致。本研究探索了斷控巖溶型溶洞多源訓練數(shù)據(jù)集的構建并在實際應用中取得了顯著成果,,同時也為其它類型儲層深度學習建模中構建可靠且多樣化的訓練數(shù)據(jù)集提供了新思路,。

Abstract

Currently, there is no comprehensive training dataset available for the modelling of fault-controlled karst caves using deep learning. In this study, we constructed prototype models for fault-controlled karst caves using outcrop data, seismic data, reliable geological models, and object-based methods. We combined, rotated, cropped, and selected prototype models from different sources to create a reliable and diverse training dataset for fault-controlled karst caves. Additionally, we constructed corresponding virtual well and probability map training datasets, all of which were used to train conditional generative adversarial networks (GANs). The trained generator convolutional neural network was applied to TH12330 well block, Tahe Oilfield. The generated multiple geological models for fault-controlled karst caves were consistent with geological patterns, conditioning well data, conditioning probability map data, and aligned with fracture structures, fractures, and cumulative production. This research explores the construction of a multisource training dataset for fault-controlled karst caves and has achieved significant success in a real application example. Furthermore, it provides new insights into building reliable and diverse training dataset for deep learning modelling in other types of reservoirs.
