As the main research object in this dissertation, DF1-1 dispir is the typical structure in diapirs area in Yinggehai basin. On the basis of analyzed logs, geochemistry materials and a large numbers of seismic profiles, the dissertation has discussed the tectonic stress field since late Tertiary, the distribution regularity of THE fault system and its genetic mechanism in DF1-1, genesis and distribution of overpressure system, characteristics of OFA. The innovative research in the dissertation is about coupling relationship between fault system and OFA.

In Songliao basin, the stronge tectonic inversion occurred in the Late Mingshui Formation, and during the declining of compressive force from the SSE to the NNW, the reactivation of basement faults formed positive inversion faults; released from thermal fluid diapirs, CO2 was migrated upward and then accumulated in inversion structural belts; as the development of fault-style inversion tectonics in the southern part is better than the northern part, and the western is better than the eastern part, CO2 is richer in the south than in the north, richer in the west than in the east in Songliao basin.

松辽盆地强烈的构造反转发生在明水组末期，挤压应力自南南东向北北西方向衰减的过程中，基底断裂复活形成正反转断层，CO2气从热流底辟体中脱出上运而聚集在反转构造带上，断层式反转构造南部比北部发育，西部比东部发育，因此松辽盆地南部比北部、西部比东部CO2气更富集。

The author has made a detailed analysis of the satellite gravity data over Wenchuan, Motuo, Zhongba, Jiashi and Taiwan Areas in China, where earthquakes more than magnitude of 6 took place in recent several decades. It is surprising that the gravity field patterns over these areas are extremely similar, which is characterized by the following features:(1)Paired positive and negative anomaly.(2)Epicenters usually were located between the pairs where the gradient of gravity field was the steepest.(3)The value of positive peak increased and its width decreased at higher order field.(4)The distance between positive and negative peaks varies in different tectonic background.(5)Different styles of crustmantle material diapirism in different stress fields. Geologically, rheological diapirism of high density crustmantle material could be a reasonable explanation to this unique pattern.

笔者详细分析了中国汶川、墨脱、仲巴、伽师和台湾等地的卫星重力资料(这些地区在近几十年来均发生过6级以上的大地震)，惊奇地发现，在这些地区，卫星重力场的样式具有极大的相似性，它们表现在：(1)卫星重力场的正负异常值成对出现；(2)震中通常位于重力场峰值间的陡梯度带；(3)由低阶到高阶的重力场正异常的峰值增大而宽度变窄；(4)正、负峰值间的距离随所处的大地构造背景而变；(5)不同应力场壳幔物质底辟的样式不同，从地质上看，高密度壳幔物质的流变底辟作用，可以合理地解释这种独特的样式变化。
