Abstract:In summing up the previous research papers on the basis of information through data collection, data analysis, a formation backstripping law (Backstrippingmethod) of the study area seven representative profile for the basin restoration of buried history, on the basis of this structure in the area Evolution for analysis. By analyzing a number of seismic profiles, described Tg7-Tg of the earthquake sequence and the reflection characteristics of geological significance, on various floors of the formation of the distribution. Layered described Cambrian - the Triassic formation, with the period of tectonic events on the sedimentary layers and structural features several important period of formation is not integrated interface, and Tajikistan low uplift tectonic evolution into paleouplift a period ( As early as the late Ordovician), paleouplift stereotypes period (late Ordovician late), the uplift of ancient period (Silurian Period to the Devonian), partial adjustment period (late Hercynian) in four phases. At the same time period the main structural style was analyzed. Papers further study of the work area and tectonic evolution of the relationship between oil and gas accumulation, Ordovician oil and gas exploration in the Tarim Basin is the main purpose of layers. Research shows that: the main source Depression, the Tarim Basin in the Cambrian an Ordovician, the first distribution of the reservoir basin structural framework and system control oil and gas, followed by the source-portfolio, integrated fault and not control. Ⅰ fracture in the tower of the study area of oil and gas accumulation effect Obviously, the fault is the major oil and gas migration channels.

Tang shan earthquake 一九七六年，中国唐山市发生大地震。 唐山大地震，是迄今为止四百多年世界地震史上最悲惨的一页。 死亡：24万2千7百69人，重伤：16万4千8百51人 二十四万人无疑是一个悲哀的整体，它们在十年前带走了完整的活力、情感…… □3时42分53．8秒…… 历史将永远铭记地球的这个坐标：东经118．2°，北纬39．6°。 人类将永远铭记历史的这个时刻：公元一千九百七十六年七月二十八日，北京时间凌晨三时四十二分五十三点八秒。 唐山市地下的岩石突然崩溃了！断裂了！仿佛四百枚广岛原子弹在距地面十六公里处的地壳中猛然爆炸！ 唐山上空电光闪闪，惊雷震荡；大地上狂风呼啸。在强烈的摇撼中，这座百万人口的工业城市在顷刻间夷为平地。 In 1976, the earthquake in Tangshan City China. Tangshan earthquake, is by far the most tragic earthquakes in the world history of 400 years of a page. Death: 240000 2000 700 69 160000 4000 800 people, injured 51 people:Two hundred and forty thousand people is a sad overall, in ten years ago tookcomplete activity, emotion...... Three forty-two - 53.8 seconds...... History will remember the earth coordinates: longitude 118.2 degrees, thelatitude of 39.6 degrees. Human history will always remember this moment: in July 28th one thousand nine hundred and seventy-six, at three forty-two in the morning Beijing time fifty-three point eight seconds. Tangshan City underground rock suddenly collapse! Fracture! As of four hundred Hiroshima atomic bomb it in from the ground sixteen kilometers of thecrust in the explosion! Over Tangshan, the lightning flashed and thunder concussion; earth whistling wind. In strong shake, this million population industrial city in an instant razed to the ground.
