摘要

平衡剖面是以嚴謹的作圖方法所建立的構造地質剖面，它是根據該剖面沿線全部可用的各種資料，包括地表上沿剖面一線良好的地質控制資料，如地層邊界和斷層出露位置及傾角變化，地下資料，如井測及震測資料，以及沿剖面走向上的各種地質特性變化所建立的構造地質剖面，所以能提供更準確的地質構造變形的模型，有助於對探勘目標所作的評估。
構造平衡法在石油探勘之應用為(1)瞭解造山運動前沉積相之關聯，(2)確定地質構造與生油和油氣遷移的相對時間關係，(3)構造解釋之重新檢驗及構造形貌預測，(4)地質構造變形量的估算，(5)推測構造高區，以及(6)找出探勘新封閉型態。

Structural balanced cross section is a geological cross section that is reconstructed base on strict method and constrained by all kinds of surface data collected along the cross section, including locations of exposed rock unit boundary and fault plane and their dip angles, and subsurface data, including well log and seismic data. Reconstruction of balanced cross section should also refer to variation in geological characters along the cross section. Structural balanced cross section is better than the conventional one in providing accurate geological deformation model and great help for evaluating prospect.
The applications of structural balanced cross section on petroleum exploration are 1) to understand the relationships of depositional facies before tectonic movement, 2) to determine the relative timing of formation of geological structures and oil generation and migration, 3) to detect the validity of the interpreted or predicted structural geometry, 4) to measure deformation rate of geological structure, 5) to predict structural high, and 6) to discover new style of structural trap.
