摘　　要：断块模式指在区域构造应力场作用下形成的断裂在空间的特定组合形式。在张性应力场中常见的断块模式有平行断块模式和环状一放射状断块模式。扭性应力场中常见的断块模式有雁列式、棋盘格式、羽状、环状一放射状和弧形断块模式。对复杂断决式油气田，提出从断块模式角度研究的思路。在对东辛油田地质特征认识的基础上，对其断块模式进行了归类总结。复杂断块式油气田的油气赋集受边界断裂控制，但不同类型断块模式中油气藏形成的控制因素、有利部位和油气的富集规律又各具特点。This paper explains the fault-block modes and their classification in extensional and torsional tectonic stress fields. In extensional tectonic stress field, there are paralleling and ring-radiating fault-block modes. In torsional tectonic stress field,there are en echelon, chess-board, feather, ring-radiating and arcuate fault-block modes. Meanwhile, based on the knowledge of the basic geological characters, the paper proposes the method to study the kind of complex fault-block oil-gas field by fault-block modes, and summaries the type of fault-block modes and hydrocarbon accumulation in Denghn oil field.
