Foreland basin is the richest in oil and gas distribution of the world's different petroliferous basins. It has more favorable petroleum geology conditions and greater exploration potential.

前陆盆地是世界上不同的含油气盆地原型中油气最富集的一类，石油地质条件优越，具有较大的勘探潜力。

Based on the integrative analysis of seismic data, log data and petrologic character, three types of sedimentary facies can be recognized in the Yijianfang Formation.

在综合分析其岩石学特征、测井资料，结合地震资料，划分出台内滩、滩间、点礁三种沉积相，并讨论了一间房组早、晚期沉积相的空间展布特征，编制了各时期的古地理图，为油气勘探提供了地质指导。

The faults moved during the early and middle period of Holocene epoch. The planimetric positions of these faults were consistent with the fault positions in the map of Tertiary geologic structure, which indicate that some fault motions were from the Pleistocene to Holocene epoch.

这些断层的平面位置与基底或第三纪地质构造图中的断层位置一致，表明有些断层活动贯穿了更新世并延续到全新世，这些勘探成果对渤海西部断层活动性的鉴定具有重要意义。

Based on the previous researches, combined with the further understanding of the present oil\|gas exploration, the exploitation of the Junggar basin, the analysis of the sedimental strata characteristics in different stages and the mountains profiles on the margin of the Junngar basin, it is considered that there are three\|period foreland basins formed since the Permain in Junggar basin.

基于前人的研究成果，结合在准噶尔盆地油气勘探开发实践中取得的新认识和对准噶尔盆地周缘盆—山耦合区带地质剖面及盆地不同时期沉积地层特征的分析，认为该盆地自二叠纪以来发育了3期前陆盆地，这3期前陆盆地及与其相关坳陷的组合和叠加是形成准噶尔盆地丰富油气资源和多样化成藏模式的主要原因。

At last, it was said it was true that an array of prospecing technicians had been selectedly assigned into 723 geological prospecting troop.

最后，据说确实有一批勘探技术人员，被挑选借调入了七二三地质工程大队。

As a result, the analysis of reservoir heterogeneity can offer a geological guidance for the study of gas distribution in reservoirs and also is in favor of the succedent exploration and development.

通过对储层非均质性及控制因素的分析，为研究储层内天然气的分布规律提供了地质基础，并有利于指导后期的天然气勘探和开发工作。

Along with horizon development well to implement, some problem became more and more gravity, such as sandbody'scale and sandbody'boundary was uncertainty and layer pressure was uneqilibrium for different well area development degree is not community. These taked a few difficulty of comprehensive evaluaterating, deploying horizon development well, adjusting well trackway for the gas field, and it might take any geologic risk.

随着该气田水平开发井的逐步实施，其含气砂体规模及砂体边界的不确定性以及由于各井块开发程度的不均一性而导致的地层压力不均衡等地质难题都日益显现出来，这些都给该气田的全面评价、水平开发井部署和井轨迹的调整带来困难，并可能引起更大的勘探开发风险。

In order to solve this problem, an improved algorithm is presented in the paper. Results from model data show that the method can diminish traveltime error in near surface model with great difference in slowness and describe accurately seismic sliding along the interface of the velocity layers.

提出了一种改进的地震波走时计算的逆风差分算法，通过考虑首波和散射波的走时，能有效地减小速度值差异较大的近地表地质模型的走时计算误差，准确地描述速度界面上折射波的滑行描述，特别适用于近地表层析成像及地震勘探中的静校正问题。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
