该深水盆地油气运聚成藏的基本地质条件亦与浅水区类似，但陆坡深水区凹陷裂陷更深、沉积充填规模更大，且发育4套烃源岩和3套储盖组合类型，使深水油气运聚成藏有了良好的基础。

The test data show that the loose scope of slope rock mass is wide, the rock mass of surface and interior of slope is from super crash to crash , the integrality of rock mass is very awful. The research result provides the reference for slope shape optimizing .

测试表明，边坡岩体的松弛层范围较大，边坡及边坡内部的岩体均为极破碎-破碎岩体，岩体完整性非常差，研究结果为凹陷露天矿边坡形状优化提供了依据。

This dissertation focuses on the basin geothermal history, tectonothermal evolution and the relationship between geothermal field evolution and hydrocarbon generation Based on the research of present-day geothermal field, geothermal history of Eastern Subdepression of Liaohe Basin was reconstructed with available data from drillings, loggings, seismic cross-sections, BHTs and thermal indicators

本文综合运用钻井、测井、地震、古温标等数据资料，在现今温度场研究的基础上对辽河盆地东部凹陷新生代热历史进行了恢复。全文以盆地热史研究为主线，进行了盆地构造-热演化分析，并探讨了温度场演化与油气形成之间的关系。

The analysis indicates the following: the fault activity rate is the most representative parameter; the fault activities in the Huimin subbasin have the long-continued, differential and episodic characteristics; and the activities of faults of lower orders have the short-term and uncertain characteristics.

结果表明，凹陷内断裂活动具有长期性、差异性和幕式性的复杂特征，低级次断裂活动具有短期性和不确定性的特点。

Among three sets of hydrocarbon Source rock in this basin, the dark-coloured mudstones in Nantun formation and Damoguai-He formation developed best and distributed widely, they even distributed in whole of the area.

海拉尔盆地的三套烃源岩，以南屯组和大磨拐河组暗色泥岩最为发育，且分布范围广，在全区均有分布，而铜钵庙组仅发育在嵯岗隆起两侧埋深大的凹陷内。

There were obvious cyclothems which consisted of evaporites, deep color mudstones or shales and deep-water turbidity sediments in Sha-4 member of Dongying sag.
