文西断裂带油气成藏模式及富集分布规律研究

针对文西断裂带的地质特点,以层序地层学、构造地质学、沉积学、石油地质学等理论为指导,以文西断裂带已发现的油气藏的解剖为基础,通过构造研究总结了研究区的断层封堵模式;通过层序地层分析,将沙二下亚段划分为三个中期沉积旋回,并进一步划分为8个短期沉积旋回,对沙三段也做了一些研究;根据沉积相分析,认为该区沙二下为洪水-漫湖亚相沉积,沙三上-沙三中为三角洲前缘亚相和前三角洲亚相沉积。在以上研究的基础上,分析不同类型油气藏成藏条件,建立了异地运聚、区内运聚、自生自储三种油气成藏模式。分析构造位置、断层封堵等油气分布主控因素,总结油气富集分布规律:含油层系多,平面上断块对油气分布影响很大;断裂带的构造位置造成了油气富集程度高;构造高部位有利于油气聚集;文西断层系弧形展布的内侧有利于油气富集。     

东营凹陷草桥—广饶潜山成藏条件研究

潜山披覆带是寻找地层岩性油藏的有利场所。东营凹陷草桥—广饶潜山披覆带地层主要包括馆陶组、沙河街组及孔店组。由于该区处于盆地边缘的构造活跃部位,地壳升降作用频繁,火山活动强烈,受多期构造运动直接影响,沉积间断、地层剥蚀、地层超覆等现象并存,致使研究区内构造特征和沉积规律非常复杂。鉴于此,通过应用地震、钻测井及地质的结合,对披覆带地层的地震、地质特征进行分析,以研究披覆地层的速度、地震反射特征为基础,总结潜山披覆地层的构造、地层及沉积规律,进而确定区内的油气成藏条件及油气藏类型。

The Nexus of Population,Energy, Innovation,and Complexity

For the past 200 years, humans have benefited from the abundant, inexpensive, and easily obtained energy of fossil fuels. Energy surpluses such as this are unusual in human history. In systems with little surplus energy, population growth is low and complexity emerges slowly due to the energetic costs it carries. On the rare occasions when energy is readily available, societies respond by growing rapidly. They must become more complex in response to the social, economic, and resource challenges of dense population. More complex societies are more expensive, requiring greater energy per capita. The process of increasing complexity necessitates greater energy production, creating a positive feedback cycle. Past societies have collapsed under such pressures. Population and complexity grew rapidly when the Industrial Revolution replaced economies based on annual solar radiation with economies fueled by fossil energy. The Green Revolution of the 20^th century is credited with preventing mass starvation, but it has made food production and sustaining population ever‐more dependent on high‐energy (low‐entropy) inputs. Some believe innovation will overcome the limitations of resources and permit unchecked growth. However, increases in complexity, innovation, and fossil energy are all subject to diminishing returns, and cannot continue to support population at current levels.

Transversals, systems of distinct representatives, mechanism design, and matching

A transversal generated by a system of distinct representatives (SDR) for a collection of sets consists of an element from each set (its representative) such that the representative uniquely identifies the set it belongs to. Theorem 1 gives a necessary and sufficient condition that an arbitrary collection, finite or infinite, of sets, finite or infinite, have an SDR. The proof is direct, short. A Corollary to Theorem 1 shows explicitly the application to matching problems. In the context of designing decentralized economic mechanisms, it turned out to be important to know when one can construct an SDR for a collection of sets that cover the parameter space characterizing a finite number of economic agents. The condition of Theorem 1 is readily verifiable in that economic context. Theorems 2–5 give different characterizations of situations in which the collection of sets is a partition. This is of interest because partitions have special properties of informational efficiency.

Structural estimation of caloric intake,exercise, smoking,and obesity

The escalating rate of obesity in the US highlights the importance of understanding the causes for this rise. In this paper I employ the First, Second, and Third National Health and Nutrition Examination Surveys to estimate a structural model of the determinants of adult obesity. To control for the potential endogeneity of some explanatory variables, such as caloric intake (adjusted for activity level) and smoking, a set of reduced form equations for these outcomes is estimated simultaneously with the obesity equation. To identify each equation, I use an array of state-level characteristics as instrumental variables. Trends in these variables shed light on the sources of the rapid increase in obesity since 1980.
