The importance and research progress in the estimation of sea-air fluxes of CO2 using remote sensing data in the recent years have been reviewed in this paper.Carbon flux estimation was based on the empirical relationships derived from sea surface CO2 partial pressure (pCO2) and relative controlling factors such as sea surface temperature,chlorophyll-a,sea-air gas exchange coefficient and so on.pCO2 fields were then created by remotely sensed data via optimum interpolations and compared with in situ data.Different types of satellite data and estimate methods adopted in different regions were discussed with regard to the temporal and special distributions of pCO2 and the controls respectively.Problems in this field and its developing tendency were proposed as well.

鄂尔多斯盆地西部余探1井下奥陶统克里摩里组顶部发现工业气藏,甲烷含量为95.603％,C2+重烃组分含量仅2.665％,δ13C1值为-39.015‰,分布于-25‰～-27.26‰之间.奥陶系烃源岩评价表明,克里摩里组上覆中奥陶统乌拉力克组为其主力烃源岩,余探1井奥陶系气藏应为奥陶系原生高成熟油型气藏.通过对靖边气田天然气组分和碳同位素特征相关性分析表明，奥陶系风化壳天然气的乙烷含量低，碳同位素
乌什凹陷白垩系舒善河组勘探程度很低.2002年,通过W1井,发现YLK气藏.2005年通过S1井,发现SM油藏.但此外先后钻探的3口井均未获得新发现,使的乌什凹陷白垩系舒善河组的成藏条件变得更为复杂.本文首先通过对单井和露头的沉积特征分析,并结合地震反射特征研究,认为乌什凹陷舒善河组主要发育两大沉积体系.同时进一步通过对三维区地震资料的精细研究，以目的层顶构造成图后发现W1井的气藏并不受局部高点的
四川盆地侏罗系石油资源量约为12～38亿吨,目前年产油约8万吨,主要分布在川中地区,产层以大安寨灰岩为主,同时沙溪庙、凉高山等粉砂岩也有少量石油产出.随着中国非常规油气理论和技术的迅猛发展,四川盆地已经成为中国非常规石油勘探开发的试验基地.本文阐述了与国内其他致密储层石油勘探盆地相比,四川盆地侏罗系的先天不足,一是生油条件偏低,TOC一般在0.8～3.2％,平均1.6％左右;二是储集物性差,孔隙度
碳酸盐岩缝洞型油藏非均质性强,目前制约缝洞型油藏高效开发的主要难点是缝洞储层的连通性识别.本文以塔北Y地区为例,地质-物探-油藏多学科相结合,形成了一套静态描述、动态验证、迭代调整的储层连通性分析技术.该套技术从碳酸盐岩缝洞型储集体的地球物理响应特征分析出发,预测出孔洞地震属性体和裂缝地震属性体,对不同地震体进行网格化运算,根据网格化后晶格间的接触关系,判断地震体间的连通性,并将生产动态特征与储层
大庆喇嘛甸油田SⅡ油层组主要发育河流-三角洲沉积体系,河流发育,具有"同期平面多变性、垂向多期河道切割叠置性"等特点,等时对比具有一定的难度.本文依据"重点井沉积时间单元划分"－"标准层控制﹑参照层借鉴对比"－"平面井网对比"这一方法,对研究区301口开发井进行了精细划分、对比,在此基础上,通过测井微相模式的建立和沉积微相的研究,精细刻画了各沉积时间单元砂体空间分布规律,实现了单一河道砂体的识别,
Considering its size and potential importance,the ocean is surprisingly poorly characterised in terms of organic gases that play important roles in global atmospheric chemistry.In this project we aim
The ocean’s influence on volatile organic compounds (VOCs) in the atmosphere is poorly understood.This work characterises the oceanic emission and / or uptake of methanol,acetone,acetaldehyde,isoprene
Carbon monoxide (CO) and non-methane hydrocarbons (NMHC) are naturally produced from the ocean surface and this oceanic source,which can have an impact on the remote atmospheric chemistry,needs to be
The flux of DMS from the ocean to the atmosphere plays a major role in the marine atmospheric sulfur cycle.The oxidation of this biogenic sulfur to SO2 and subsequently to sulfate aerosol (which can a
