油气成藏流体动力系统分析的基本原理是在一个含油气盆地内划分出不同的流体动力系统 ,并按每个系统的类型 ,研究其成藏条件。该原理应用到柴达木盆地西部 ,在柴西地区纵向上比较典型地划分出 N32 — N22 — N1 2 、N1 2 — N1 — E23 和 E23—E1 3 三个油气成藏流体动力系统 ,它们分别为重力驱动型、压实驱动型和封存型系统 ,分析了这三个系统的成藏条件 ,指出应把 N1 2 — N1 — E23 系统中的 N1 层系和 E23 — E1 3 系统中的 E1 3 层系作为今后主要的勘探目标层系。
Hydrocarbon accumulation Hydrodynamic system analysis of the basic principle is in a petroliferous basin divided into different fluid dynamic systems, and according to the type of each system to study the accumulation conditions. This principle is applied to the western part of the Qaidam basin. Three hydrocarbon accumulation fluid dynamic systems, N32 - N22 - N1 2, N1 2 - N1 - E23 and E23 - E1 3, are typically divided longitudinally in the region of Chaixi. For the gravitational - driven, compaction - driven and sequestration systems, the accumulation conditions of these three systems are analyzed. It is pointed out that the N1 layer in the N1 2 - N1 - E23 system and the E1 3 in the E23 - E1 3 system Strata as the future of the main exploration target strata.
