Surface effects of triggered fault slip on Reykjanes Peninsula, SW Iceland

Three large earthquakes (M_w>4.5) were triggered within 5 min, 85 km west of a M_w 6.5 earthquake in the South Iceland Seismic Zone (SISZ). We report on surface effects of these triggered earthquakes, which include fresh rupture, widespread rockfall, disrupted rockslides and block slides. Field data confirm that the earthquakes occurred along N-striking right-lateral strike-slip faults. Field data also support the conclusion from modeling of InSAR data that deformation from the second triggered event was more significant than for the other two. A major hydrological effect was the draining of water through an open fissure on a lake bed, lowering the lake level by greater than 4 m. Field relationships suggest that a component of aseismic slip could have been facilitated by water draining into the fault zone.     

场论理论在经济客体地位评价中的应用：以河南省城市地位为例

一个 经济客体地位的评价不能单从该经济客体本身来考虑，它还与评价区域周围其它观察经济客体有关，会受到其它经济客体的衬托作用。经济客全的地位应包括评价经济客体在其它经济客体的“势”和其它经济客体在评价经济客体处的“势”两部分。     

评价储层含油性的热解参数校正方法及其应用

评价储层含油性时，热解参数Ｓ１＋Ｓ２是一项有效参数。其中Ｓ２相对稳定，Ｓ１则随样品类别或露置时间的不同而发生变化。岩心样品的随钻解分析值比较接近真实，岩屑和井壁取心样品的Ｓ１会明显损失。而目前多数探井心进尺少，大多为岩屑录井。     

氰化液中Ag的现场测定

已往测定氰化液中Ag的方法只适用于化学成分简单的样品，对于成分较复杂，尤其是Cu，Pb，Zn浓度较高的氰化液，其测定Ag的重现性较差。现场测定氰化液中Ag的方法是基于采用HNO3 H2O2(过氧化氢)破坏氰化液中的[CN]-，在10％HNO3介质中以CCX富集分离Ag。吸附在CCX上的Ag经灰化法解脱后在pH值为3．3的CH3COOH(乙酸)-CH3COONa(乙酸钠)缓冲溶液中，以Au试剂液珠萃取比色法进行测定。选择一个已知含量的氰化液进行10次测定，方法的测定下限为0．1μg／mL，RSD为5．8％，分析结果能满足选冶生产工艺的需要。     

Experimental research on reservoir sensitivity to stress and impacts on productivity in Kela 2 Gas Field

Kela 2 Gas Field, with high formation pressure (74.35MPa), high pressure coefficient (2.022) and difficulty of potential test and evaluation, is the largest integrated proved dry gas reservoir in China so far and the principal source for West-East Gas Development Project. In order to correctly evaluate the elastic-plastic deformation of rocks caused by the pressure decline during production, some researches, as the experiment on reservoir sensitivity to stress of gas filed with abnormal high pressure, are made. By testing the rock mechanic properties, porosities and permeabilities at different temperature and pressure of 342 core samples from 5 wells in this area, the variations of petro-physical properties at changing pressure are analyzed, and the applicable inspection relationship is concluded. The average productivity curve with the reservoir sensitivity to stress is plotted on the basis of the research, integrated with the field-wide productivity equation. The knowledge lays a foundation for the gas well productivity evaluation in the field and the gas field development plan, and provides effective techniques and measures for basic research on the development of similar gas fields.     

安塞油田杏河地区长6油层沉积微相研究

在岩心描述的基础上，对杏河地区长6油层沉积相进行了分析，提出了该区主要沉积相为湖泊环境的河控三角洲体系，主要为三角洲前缘亚相沉积，主要沉积微相有水下分流河道、分流河口砂坝、前缘砂席和分流间等，分流河道和河口砂坝是本区占主导地位的骨架砂体。该区长6油层的三角洲体系是安塞三角洲体系最早发育的一支，早期分流来自于北部，后期分流转由东北方向进入，由于各期分流河道迁移、袭夺、决口以及因压实的均衡调整等，从而形成三角洲复合体内部各分流三角洲砂体的相互叠置交错。根据岩心微相分析、小层砂体形态和测井剖面对比分析，对该区长6油层砂组及小层的沉积微相进行了研究，掌握了沉积微相的时空展布和变化规律。     

渤南油田中部古近系沙河街组低渗透储层岩石学和成岩作用

该区储层岩石类型主要为岩屑质长石砂岩，溶解作用是主要的建设性成岩作用，压实、自生矿物充填和胶结作用是主要的破坏性成岩作用，成岩阶段处于晚成岩A亚期。该区储层较高的孔隙度是晚成岩期强烈的溶解作用形成次生溶孔的结果，而储层砂岩较低渗透率的主要成因机理是成岩期各种自生矿物的充填和胶结作用；此外，溶蚀作用形成的孤立、互不连通的粒间孔也是形成低渗微细喉道储层的主要原因。有利孔隙组合为粒间溶蚀孔-原生粒间孔-粒内破碎缝，有利储层的分布受砂体分布、构造配置及成岩作用的联合控制。     

Pollution history and recovery of a boreal lake exposed to a heavy bleached pulping effluent load

We examined the effects of heavy pulp mill discharges on the Lake Lievestuoreenjärvi ecosystem and the later recovery of diatom and chironomid communities from age-dated short core samples. Beginning in 1927 the lake received a heavy effluent load from a sulphite pulp mill. Except for the recession during the Second World War and the temporary closure of the mill from 1967 to 1971, the industrial load, containing large quantities of nutrients, organic matter and toxic compounds, increased continuously. In the early 1980s, laboratory documents were falsified by the directors of the mill and the systematic illegal effluent overload led to a collapse of the whole lake ecosystem. In 1985, the outdated plant was finally closed down. Based on the assessment of chemical properties and biological remains of the sediment, we distinguished five developmental phases in the ecological state of the lake. In the pre-industrial phase, the pelagic and profundal benthic communities were dominated by species preferring ultraoligotrophic or oligotrophic lakes. Concomitant with the increasing discharge and deposition of chlorine compounds, resin acids, and mercury, as well as strong acidity and hypolimnetic and epilimnetic anoxia, the ecological status changed in a short period from excellent to bad. Finally, in the early 1960s, the majority of the lake was virtually dead and the aquatic life survived only in the uppermost littoral zone. Since 1985, a fast recovery in the water quality has led to a strong, but temporary eutrophy in pelagic communities. The main peak of eutrophication was caused by the invasion of a species new to the lake,Aulacoseira granulata var.angustissima. Later, the pelagic communities shifted towards oligotrophy, but the original, pre-industrial status has not been re-established. The profundal benthic communities have not achieved the pre-industrial structure, but at present indicate mesotrophy.
