结合临清坳东部存在多层系烃源岩、多个油气生成运移聚集区域的特点，对临清坳陷东部的油气系统按二个层次进行了划分，第一个层次以烃源岩为核心，用烃源岩+可靠性来命名；第二个层次以次级构造单元为核心，包含了油气生成运移聚集的可能区域，用源岩名+构造单元名+可靠性来命名。

The process of balance is on thealternation of arch and beam、 explores the space-time law of separatedstrata"s occurrence、 development and distribution and this paper damasks theoverlying rock as injecting zone and no-injecting zone from the aspect of controllingoverlying rock.2.The separated strata is over fracture zone and under integral crook zone inwhere the rock formation"s moving is of monolayer or of many layers more oftenthan not, and the thickness of strata is very small while comparing with integralcrook zone.

通过物理模拟及数值仿真模拟的实验研究，分析了采动覆岩的移动与破坏过程，提出了采空区上方覆岩的平衡形式是以拱和梁交替作用来实现平衡→失稳→再平衡的力学过程观点，并详细研究了覆岩中离层产生、发展与分布的时空规律，进而从覆岩控制角度划分了可充填离层带与不可充填离层带，为实际应用奠定基础； 2。
