天然气

In the past few years , the QingDao government regulates her energetic structure , step by step limits the use of coal and oil , encourages natural gas ; simultaneously natural gas becomes the prerequirement for real estate development .

近年来，青岛市政府实施能源结构调整，逐渐限制煤炭与燃油的使用，积极鼓励使用天然气；同时天然气也成为房地产开发的先决条件。

Petroliferous gases mainly refer to the associated gas of crude oil, including petroliferous pyrogenic gases and petroliferous cracked gases.

中国经过20年天然气科技攻关，已形成天然气成因类型及其鉴别标志的理论体系和方法。

In a view of the theory of the traditional oil and gas formation it is considered that the oil and gas resources buried in sedimentary basins are generated by OM in source rocks during thermal evolution and marine, lacustrine sapropel and humic-sapropel OM is the mater of the formation of considerable oil and gas but coal-measure strata is relatively bad source rocks, being considered that they can not generate significant amounts of oil and gas.

传统的石油天然气成因理论认为蕴藏于沉积盆地的油气资源是由烃源岩中的有机母质在热演化过程中形成的，而且是海相或者湖相腐泥型和腐泥－腐殖混合型的有机质有利于形成大量的石油和天然气，而煤系地层相对是较差的烃源，认为这种烃源岩不能形成大量的油气。

2The natural gas of Ordovician is typical petroliferous gas which came from the same source rock. It is a composite of gas that was generated from the sapropelic parent material of different maturity. Its maturity varied from mature degree to high-over mature degree which decreased from east to west and from southeast to northwest.

2塔河油田奥陶系天然气为典型的油型气，具有相同的来源，为腐泥型母质不同成熟阶段生成气的复合，成熟度范围覆盖从成熟阶段到过成熟阶段，成熟度从东往西、从东南向西北逐渐降低，天然气的产生具有多阶连续的特征。

It was found that the quenching diameter of porous media is a multi-parametric complicated function, related to the mixture flow speed, the premixed gaseous laminar flame velocity, the pipe flow Reynolds numbers, the coefficient of temperature conductivity, the equivalence ratio and the soUd temperature.

为缓解能源结构不合理造成的环境污染问题，我国加快了天然气的使用力度，发展高效、低污染排放的天然气燃烧技术具有非常重要的现实意义。

Aimed at the existed factors of safety during stevedoring operation of LNG, its important for us to give out some suggestions and measurea which can help us stevedoring safely.

液化天然气装卸作业中存在的危险性主要是由于液化天然气本身的低温、高压、易燃易爆等潜在特性所致。

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。

With the development of oil drilling and the increase of the deep ocean drilling,the requirements of drilling additives were also promoted to satisfy the high temperature resistance and salt resistance.2-Acrylamido-2-methylpropane sulphonic acid is an acrylamid derivatives with -SO3H and -CH2=CH2- in its molecular structure.

随着世界能源需求的增加和钻探技术的发展，向地层深部挺进，向深地层要油气已成必然。在我国，这种现象尤为明显，作为全国石油天然气产量的主力接替区的西部，其石油资源量的73%、天然气资源量的52%都埋藏在深地层。

For gas tankless water heaters , the same gas supply line and/or venting may need to be sized larger than for a typical gas tank.

天然气tankless热水器，同样的天然气供应线和/或排气可能需要更大的规模比一个典型的煤气罐。

U.S. Rockies: We explore for and produce natural gas, crude oil and natural gas liquids in the Denver-Julesburg, Green River, Powder River and Uinta Basins.

美国洛矶山：我们探索和生产在丹佛朱尔斯堡，青河，粉河盆地和诺尔尤因塔天然气，原油和天然气液体。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
