Statistic analysis indicated that three kinds of irregular components show complicated random characteristics, and their probability density distributions change with increasing gas velocity, that is, irregular occurrence time fluctuations of all three kinds of elements of heterogeneous structure (the dilute phase, the dense phase and the dilute/dense cycle elements) evolve similarly from symmetric distribution similar to Gauss distribution at low gas velocities to double-peak distribution at medium gas velocities, and become dissymmetric single-peak distribution at high gas velocities.

相关分析表明：动态行为中的三类非规则波动呈随机性；直方图分析表明：随表观气速变化，非均匀结构的各种非规则波动的概率密度分布均具有复杂的演变；其中，对于时间非规则波动，其演变趋势是：小气速下的单峰分布、中气速下的双峰分布和高气速下的非对称单峰分布。

Sulige Gas Field has low porosity, low permeability, low abundance, strong heterogeneity, complicate geological condition and is not very good at effective sand body continuity and connectivity, and so on. It is observed that gas well productivity of this gas reservoir is low, formation energy supply not enough, single well drainable gas is finite.

苏里格气田具有低孔、低渗、低丰度，非均质性强和有效砂体连续性、连通性差等特征；从已有的试井动态资料可以看出，该类气藏气井产能较低，地层能量供给不足，单井可采气量有限。

Synchronous parallel-type refers to the oil-gas system formed a relatively independent oil-gas system in the same stratigraphic range. Heterochronous polymeric-type refers to the stratigraphic and regional range overlaid in oil-gas systems which formed in different period. Synchronous cross-type refers to a mode of regional ranges crossed of two oil-gas systems.

同期并列式指含油气系统在同一地层范围形成彼此独立的含油气系统；异期叠合式是指不同时期形成的含油气系统地层范围，地区范围重叠的组合方式；同期交叉式是指两个含油气系统地区范围交叉的组合方式。

The article mainly discusses tunneling when there is more gas in the coal layer,utilizing the hish layer cracks using the hole in the high layer,in this way of inhaling the next layer gas as tunneling,the problem of the gas consistency above the ordinary level in some workplace because of the gas gushing form the next layer is sloved.

主要阐述了在高瓦斯煤层掘送时，利用高孔裂隙，采用高抽放钻孔、边掘边抽的方法，解决邻近层瓦斯涌出造成工作面局部瓦斯超限的问题。

One, corrode gas and corrode energy of life of plant of phenomenal Jiang Mou to bilge aluminous canal shoeshine, plunge into a bleed with the injector that takes syringe needle, in the analysis on appearance of gas phase color atlas, the result makes clear, in what taking gas hydric occupy 72% above, the others gas is nitrogen, not check gives oxygen.

一、腐蚀气体与腐蚀现象将某厂气胀铝管鞋油，用带针头的注射器扎通抽气，在气相色谱仪上分析，结果表明，所取气体中氢气占72%以上，其余气体为氮气，未检出氧气。

Making inventory is a process which tracks down inventory, storage capacity, working gas volume and cushion gas volume in multicycle operation of underground gas storage. This process is a key step to study the UGS operation rule, analyze the gas loss, improve the operating efficiency, and reduce the cost.

地下储气库多周期运行盘库过程，是对气库库存量、库容量、工作气量以及气垫气量的全过程实施跟踪的过程，是研究气库运行规律、漏失分析以及进一步提高气库运行效率、降低运行成本的关键环节。

The acid gas and nonacid gas are calculated with established model.The calculated results show that the average relative deviation of temperature for acid gas hydrate production is 0.33%;for nonacid gas,the relative deviation is 0.113%.

通过检验：该模型在预测酸性气体水合物生成温度时的平均相对误差为0.33%；对非酸性气体的偏差仅为0.113%，算例表明本模型计算方法简单，使用十分方便，具有较高的精度，能够满足工程要求。

This three region model is different from two region model available. The behavior of the nitrogen in the volume compensator was simulated by polytrophic process similar to real variety process of gas, or constant temperature process of gas with the valve opening in the volume compensator and adiabatic process of gas with the valve closed in the volume compensator, respectively. The former were closed relatively to real variety process of gas space nature.
