| 摘 要： | 很多事例表明，含油气盆地或含油气地层及其中的一切物质（包括油、气、水等）的运动，都主要受地应力驱动的控制。在地应力作用下，含油气盆地或含油气地层中分散的油气，通过岩石介质形变产生的应力梯度（所造成的压力差异）的变化，而实现的“应力聚集”作用。在这种作用下的油气运移聚集和圈闭成藏，即是“应力圈闭”作用的结果。

| Abstract: | Many facts show that the oil-gas-bearing basins or oil-gas-bearing stria and the movement of any substances being contained in it (including oil,gas,weter and so on)are all controlled by the earth stress. Virtually,stress trap means a stress concentration process.The dispersal oil and gas in the oil-gas-bearing basins and strata,under the action of earth stress, will be concentrated due to the presence of stress gradient (pressure difference) resulting from the rock deformation. The migration,accumulation and trap reserviors are an unified process,which is under the control of tectonic evoluation of oil-gas-bearing basins and happened at the same time. The oil-gas accumulation or reserviors formed in the course of this process are the results of stress trap process. |
