This article that focuses on the systematic and in-depth research in the current primal problem about abnormal burst pressure reservoir depress burst pressure has procured following main fruits:1 It forms the method which could obtain massive vertical static state mechanics parameters.2 In a foundation of acquisition of rock mechanics parameters,apply bent lamella that as mechanical model along with characteristic of actual geologic characteristics to analysis curvature for anticlinal strcture, get homologous tectonic stress value throug relation between the curvature and stress and different principal curvature in anticlinal structure,consequently set up laminational stress model for anticline reservoir. The block lamination for existed fracturing date has formed method of setting up mechanical model of lamination terrestrial stress by abtaining the block tectonic stress coefficients which are got by complex utilization test, laboratory test and fracturing date playback.3 Analysesing the main reason which lead to high burst pressure by considering the characteristic of reservoir geology,reservoir,and rock mechanics and reservoir damage,etc.Establishing burst pressure quantitative prediction model which provide gist for depressing construction risk and optimizing construction craft under the condition of open hole completion ,gun-perforated completion and damaged reservoir.4 Provding theoretical basis for interpreting acidification pretreatment which could depress busrt pressure by finding the relation between the influencing factors and rock machanics parameters and analysing the factors that have effect on rock mechanics parameters. Expounding the mechanism of reaction of mixed monomineral and acid from the angle of microcosmic element, evaluating quantitatively acid sensilility of different kinds of mineral effectively, and determing the first-order reaction dynamical equation of each mineral.5 Revealing rock mechanics property chage as a result of acid flooding in different condition by sandstone traumata experiment in different temperatures which combined with rock mechanics triaxial stress experiment.6 Associating damage mechanics with sandstone acidizing, established sandstone damage mechanics model in the foundation of the recognition on the rock mechanics parametric variation which is caused by acid-rock reaction in both macroscopic view and microscopic view ,also demonstrated those processes and quantitative estimated the acid busrt pressure to direct the site operation.
本文针对目前异常破裂压力储层降低破裂压力的主要问题展开较为系统和深入的研究,取得了以下主要成果:1形成了利用测井资料,结合室内岩芯测试结果,获取静动岩石力学参数的相关性特征,从而获得纵向上大量静态力学参数的方法。2在获取了岩石力学参数的此基础上,利用弯曲薄板作为力学模型,结合区块实际地质特征对背斜构造进行曲率分析,通过曲率与应力的关系,利用背斜构造不同部位的主曲率求得相应的构造应力值,从而建立起背斜储层的分层应力模型;对已有压裂资料的区块分层,形成了综合利用测试、室内实验、压裂资料反演获得该区块构造应力系数,建立起分层地应力的力学模型的方法。3综合考虑储层地质、油藏、岩石力学特性和储层伤害等因素,分析造成高破裂压力的主要原因,综合利用岩石力学、弹性力学等知识,建立了裸眼完井、射孔完井条件下以及储层受到伤害后的储层破裂压力定量预测模型,为降低施工风险和优化施工工艺提供了依据。4完成了物性、岩性影响岩石力学参数的因素分析,找出了各影响因素和岩石力学参数之间的关系,为从机理上解释酸化预处理降低破裂压力提供了理论基础;从微观元素的角度阐述了单矿物与酸反应的机理;并在此基础上,有效评价了各种矿物的酸敏感性,定量确定了岩石中各矿物的一级反应动力学方程。5完成了不同温度下的酸液类型、酸液浓度、注酸量等一系列砂岩损伤实验,结合岩石力学三轴应力实验,系统揭示了在不同条件下注酸而引起的岩石力学性质变化。6将损伤力学与砂岩酸化相结合,在宏观、微观两个方面认识酸岩反应引起岩石力学参数变化基础上,建立了砂岩损伤力学模型,并对其进行验证,在此基础上定量计算酸化后的破裂压力,有效指导现场施工

Assuming that half of the carbon loss in the degraded terrestrial ecosystem in current forest and grass areas are restored during the next 50 years or so, the terrestrial ecosystem in China may sequestrate~12.0Pg of organic carbon from the atmosphere, which represents a considerable offset to the industry's CO〓 emission.
5在现有的气候条件下,未来50年或更长的时间上,如果我们能通过有效的土地利用措施使我国现有林地和草地面积上的生态系统碳损失量恢复其中的1/2,那么我国陆地生态系统将具有~12.0Pg C的碳汇潜力。

The BBC's "Correspondent","Newsnight" and "Horizon", all current-events programmes, are watched by only half as many multichannel homes as by terrestrial-only homes. ITV's "Pop Idol" is watched by only 16% fewer. The drop in "Newsnight" viewing was 17 percentage points greater among poorer viewers than among richer ones. Soap operas, light entertainment, daytime TV, sport and lottery programmes attract a much higher proportion of poorer viewers, the corporation notes.
比如BBC的"通信者""新闻之夜""地平线"以及所有实事类节目,在装有多频道电视的用户中,这些节目的观众数量只有那些一般电视用户同类观众的一半,ITV的"平民偶像"的穷人观众比富人观众多了17个百分点,肥皂剧、轻喜剧、日间节目、体育和彩票类节目更是穷人观众的最爱。

However, this does not disprove that short changes in intensity or direction of the Kuroshio ever occurred at certain short cooling events. The 10Be minimum during the Younger Dryas event may indicate that the Kuroshio had been once greatly weakened or even terminated in the Okinawa Trough area which could be related to the response of the Pacific Ocean to the Younger Dryas. The 10Be and 9Be in surface sediment show totally different distribution patterns. The 10Be distribution is dominated by the input from Kuroshio and its branch, the Yellow Sea Current, whereas 9Be is mainly influenced by terrestrial input of suspended materials from the Yellow River discharge and deposited in the fine-grain size sediment zone southwest of the island of Jeju. Both 10Be and 9Be distribution patterns are different from anthropogenic pollutants such as heavy metal Pb which is dominantly distributed closely to the coastal areas.
冰期时冲绳海槽北部10Be的沉积通量远远高于太平洋大洋海区,充分反映了黑潮的传送带作用和边缘海的聚焦沉积作用,并表明末次冰期时在千年尺度上黑潮仍流经冲绳海槽,且强度并未减弱。10Be的通量在新仙女木时降到整个岩芯所跨时期的最低点,甚至低于10Be的现代大气平均生产率,因此推测在新仙女木事件时,黑潮的变动特别大,有可能改向或断流。
