Consider to think, although apparent gaseous state is not had in 0 derv of the interfuse in artesian well fluid,hydrocarbon exists, but fall in certain environmental temperature condition, the volatilization with have certain free hydrocarbon composition appears C_(11 the following liquid state volatilizes hydrocarbon , what cause gas to measure complete hydrocarbon thereby is unusual, but the change that this won't cause gas to measure constituent to be worth however, use this one characteristic, can lift with complete hydrocarbon and the method with not elevatory firedamp will distinguish the complete hydrocarbon holiday that mixes fluid of derv artesian well to cause is unusual.

探究认为，虽然钻井液中混入的零号柴油中并无明显的气态烃存在，但在一定的环境温度条件下，将有一定的挥发游离烃成分出现C_(11以后的液态挥发烃，从而引起气测全烃的异常，但这却不会引起气测组分值的变化，利用这一特征，就可以用全烃升高而甲烷不升高的办法来区分混柴油钻井液引起的全烃假异常。

The net result is a continuous flow of gas, starting as hot gases in intergalactic space and ending as a drizzle of cool gas called a "cooling flow," falling into the central galaxy.

直接结果是气体的连续流动，一开始是星系间的热气，最后成为一股冷气，即"冷流"，流向中心星系。

所有的气路答保留肮脏，惯路边壁不得有尘埃、纤维、杂物、异物的活命，制止畅达气路，感化抽气，以保留惯路的畅达。

For a start, before the seismic inversion it is essential for a reservoir to enhance the basic research of the rock geophysical characteristic analysis, horizon calibration, fidelity processing and model analysis, etc., and of the reservoir's lithologic character, physical, electrical and gas bearing property. Subsequently based on the fundamental principle of seismic inversion, a series of inversion methods and their application conditions were emphasized. Finally, taking Labureng area as a target, by comparing various inversion effects, we aimed at enhancing the precision of seismic image, increasing SN ratio and resolution, and highlighting seismic responses of the target strata, and presented reliable geophysical references for the understanding of reservoir evaluation, gas bearing modelbuilding and reservoir mechanism in HJQ area.

首先把地震反演前的基础研究工作做扎实，其中包括储层的岩性、物性、电性、含气性在内的岩石地球物理特征分析、层位标定、保真处理和模型分析等；其次从地震反演方法技术的基本原理出发，重点探讨各种反演方法的技术特点和应用条件；最后以杭锦旗地区拉不仍工区为靶区，通过对不同地震反演方法处理效果的综合对比分析，以提高地震成像精度、提高信噪比和分辨率、突出目的层段的地震响应特征为目标，为杭锦旗地区储层评价、含气模式建立，成藏规律的认识提供可信的地球物理依据。

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。
