Then, the steady-state productivity model for horizontal well in gas reservoir is established. On the basis of solving the model, this thesis deduces the binomial deliverabiliry equation by which absolute open flow potential and inflow performance relationship can be gotten and we can forecast the production performance of horizontal well in gas reservoir.

其次，在建立水平气井稳定渗流的数学模型并求得其解的基础上，推导出了考虑地层伤害及非达西渗流影响水平气井二项式产能方程，通过该二项式产能方程可求出水平气井的绝对无阻流量，绘制流入动态关系曲线来预测生产动态。

After achieving the solution of the mathematical model,a binomial productivity equation of gas-water well with two-phase flow in formation was derived in consideration of the influence of formation damage and non-Darcy effect,thus establishing the theory of transient inflow performance relationship curve of gas-water well.

文章基于质量守恒原理，建立了气水两相地层瞬态渗流的数学模型，通过定义气水两相拟压力函数，将渗流数学模型线性化，在获得数学模型解后，考虑地层损害和非达西效应的影响，推导出在地层中为水气两相渗流的气水同产井的二项式产能方程，从而建立了气水同产井瞬态流入动态关系曲线的理论。

Horizontal gas well model considering well-bore structure parameters, turbulent flow under high-speed non-Darcy flow and start-up pressure gradient was established and solved. Binomial deliverability equation describing horizontal gas well was derived.

建立和求解了包含水平气井井身结构参数、近井区高速非达西渗流条件下气体紊流因素以及启动压力梯度效应的水平气井渗流模型，推导出了描述水平气井产能的二项式产能方程。

The binomial deliverability equation can only be used to describe the high velocity non-Darcy filtering flow. For low permeability fracturing gas wells, due to low permeable property and high flow conductivity of the formation, the filtering flow laws of the formation are different from those before fracturing, and binomial deliverability equation can not be used for the flow condition of gas wells, therefore, new equation is needed.

二项式产能方程只能描述高速非达西渗流，对于低渗压裂气井，地层的低渗透性和裂缝的高导流能力使得其渗流规律已经和压裂前大不一样，二项式产能方程已无法描述气井的生产状况，必须建立新的方程。

研究表明，该气藏属较大规模的自生自储型生物成因气，成藏条件良好。

Tear gas and sneezing gas: Odor resembles pepper, spicy mustard or bitter almond oil.

催泪瓦斯和打喷嚏气体：气味：类似于辣椒，辣芥末或苦杏仁油。

Coalbed gas reservoir simulator in 1.0 version is developed by modifying source code of Black Oil Simulation procedure BOAST II, the simulator breaks through the limitation of others coalbed gas reservoir simulation software that dont take coal matrix shrinkage into account.

修改黑油模拟程序BOAST Ⅱ源代码，发展了一个煤层气模拟器，该模拟器突破目前大多数煤层气模拟软件不能考虑煤基质收缩影响所存在的局限性。

The mainest environment problem has the whole world air temperature to change now warm, air pollution , water resource contaminate wait, specifically for all above problem, blowoff I think that the primo ought to control the automobile tail gas, the tail gas sends warm air pollution to make and the air temperature is changed into more than the correct or required number to have interwovenness relation , secondary, the industrial sewage and domestic sewage overanxious and purifying, cut down contaminating to water resource.

现在最主要的环境问题有全球气温变暖，大气污染，水资源污染等，针对以上问题，我觉得首先应当控制汽车尾气的排放，过多的尾气派发与气温变暖和大气污染有着密不可分的关系，其次，过虑和净化工业废水和生活污水，减少对水资源的污染。

Assumes that molecules are rigid ball, intermolecular End X are all elastic collision, in addition to the instant of collision, the molecular force can be ignored, then the chemical pure gas, K = 4nd2πkT = 4d2pπ, where: k for XmSkTSm Boltzmann constant, m is molecular weight, d the molecular diameter, n the molecular number density, p the gas pressure, T is thermodynamic temperature.
