两点射线追踪是解决复杂地质结构下反射波射线正演的有效方法。在初至波层析射线追踪算法基础上,提出了一种两点射线追踪方法,利用层析网格对模型进行离散化,通过两阶段法射线追踪,分别对激发点和接收点按向前处理过程计算模型单元及节点的旅行时,两次时间相加作为最小旅行时,再在目的层界面邻域扫描最小旅行时子震源网格单元,用粒子群算法在该单元内扫描全局最小旅行时点,得到反射点位置与反射夹角,再利用向后处理过程运用旅行时线性插值算法,从反射点分别到激发点、接收点反向追踪射线路径,最后得到反射波两点射线路径。

Damming landslides are very common in china, they ever blocked the rivers and streams completely or partly, and form natural lakes. Now more than 150 damming landslides in china are recognized through field investigation and data collection indoors. These Landslides distribute in steep mountainous counties around the Qinghai—Tibet Plateau, and mainly of which in southwest china and northwest china.. Studies show that the distribution of damming landslides has a close relation with the event of the Tibet plateau upheaval. The thermodynamic effect on the free atmosphere results from rapid upheaval of Qinghai\|Tibet plateau is more and more intensive, it causes air to circulate from east to west. In winter, the high Tibet Plateau leads the cool air gather quickly and high cool potential to be stronger. On one side, an anticyclone cool high pressure forms near the ground surface at the altitude of 4000～5000m, and produces winter monsoon wind. On the other side, the shielding effect of the plateau impedes the air from Siberia touching with the air from south Indian Ocean, which causes the cool air from Siberia enters china frequently and strengthens the cool and drought in northwest china. In summer, the monsoon wind is impeded by the plateau and cannot enter into north china, where it is dry, it can only moves around the plateau and at the edge enters into southwest, south, middle and east china, where the rainfall process is strong. Thus south and east of the plateau become the areas with many damming landslides resulted from heavy rain.

2008-09-24强降雨过程导致汶川震区北川县城魏家沟泥石流暴发,对老北川县城造成了严重的破坏。由于这场泥石流灾害发生在汶川地震高烈度区,是地震与降雨共同作用下的结果,研究其形成与成灾过程,对于进一步认识强震区泥石流发育特征具有重要的意义。根据现场调查和高分辨率航空图像解译,分析了魏家沟泥石流流域特征,特别是地震条件下的泥石流物源特征,在此基础上讨论了泥石流起动过程和堆积过程。魏家沟泥石流典型实例表明了汶川震区泥石流已进入一个新的活跃期。因此,应该开展对汶川地震区的泥石流风险评估和监测、早期预警等研究,采取有效的工程措施控制泥石流的发生和危害。

The fault system of Liaodong Bay developed extensively under the control of the Tanlu Fault. The fault system can be grouped into strike-slip faults of grade Ⅰ, trunk faults of grade Ⅱand branch faults （induced faults） of grade Ⅲ respectively based on its developmental scale. The faults of grade Ⅰ and Ⅱwere deep, early and large while the faults of grade Ⅲwere shallow, late and small. The formation, evolution and distribution features played a significant role in controlling the migration of oil and gas in both horizontal and vertical directions. The fluid transfer in the fault system occurred in the process of faulting. The strike-slip and trunk faults moved actively forming predominant pathways for oil and gas migration. The branch faults, with weak activity, generally controlled the development of traps and were beneficial for the accumulation and preservation of oil and gas. The faults of grade Ⅰ and Ⅱ formed the major migration pathways for oil and gas, but their fault activity rates appeared to vary along their strikes. The zones with a relatively low fault activity rate might be favorable for oil and gas accumulation. When the activities of strike-slip, trunk, and branch faults came to a halt, the fault seal behavior had a vitally important effect on the accumulation of oil and gas. The controlling role of the fault over fluid distribution was further analyzed by calculating the fault activity quantitatively.

在塔里木盆地LS地区,泥盆系和志留系的地层圈闭和岩性圈闭是重要的勘探目标。然而,受地震资料分辨率的限制,这类圈闭的落实程度较低。为此,在LS地区开展了提高分辨率VSP井控地震资料处理技术研究。通过分析VSP资料,求取球面扩散振幅补偿因子;对VSP走廊叠加剖面与地震资料进行匹配分析。优选反褶积参数;通过分析零偏VSP资料,计算时变Q因子;对地震资料进行时空变Q分析,并由VSP资料进行校正,得到时变Q补偿因子。通过井控地震资料处理技术处理后的资料,分辨率有了较大提高,对砂岩尖灭点和志留系内幕的描述更加准确。

Lanping basin was a massif (land massif) in late Palaeozoic Era. The ocean of Jinshajiang separated it from Yangtze plate in east. Lancangjiang ocean separated it from Yunnan—Tibet plate in west. From late Permian Epoch, the oceanic crust of Jinshajiang subduced the west from east, the one of Lancangjiang down went the east from west, and then the Yunnan—Tibet ancient land gradually closed to the Yangtze. In the end of the Permian Period, two continents and Lanping plate touched together, and the evolution history of the Paleotethys was end. Hercynian orogenic belt in the east and west sides of Lanping had volcanic rock colliding in early—middle Triassic Epoch. In Ladinian in middle Triassic and Carnian in late Triassic, the north side of Lanping basin formed the serial volcanic rock of spilite—quartz keratophyre because mantle\|derived magma causing by delamination rose and mixed with the constituent of continental crust. The volcanic rock overlapped the middle Triassic and late Palaeozoic stratum in angular unconformity. It was the feature of double peak or evolution from the basic to the acid. The race element distribution of volcanic rock was same as the one of tholeiite in island and inter\|arc basin. The rate of lead isotope of the volcanic rock was much higher. These points all distributed above the NHRL in Pb\|Pb. This indicated that the Pb of volcanic rock was the mantle\|derived magma mixed with crust one. The large\|area progression in Lanping rift basin begun in late Carnian.. The east side in Lanping basin developed the sedimentary system that was granule gravel (grit) rock in border facies—limestone in beach facies—black shale, and the middle had black shale, banded siliceous rock, brecciform limestone in late Carnian to Norian. The geochemistry research of siliceous rock showed that the genesis of the chert was hot water. The development of brecciform limestone was related with action of central\|axis rift. The Lanping rift basin went into consuming s
