Performance Rule Prediction in Gas Production by Water Withdrawal for Water Drive Gas Reservoir

水驱气藏排水采气动态规律预测

It is proposed that "finding gas by water withdrawal" can be applied to the fractured reservoir in the compacted sandstone of the UPPer Triassic in Sichuan Basin.

在四川盆地上三叠统致密砂岩裂缝性储层中，同样可以通过水井排水找到钻井未曾发现的天然气。

The greenhouse gas withdrawal grew unceasingly causes the Earth temperature to elevate continually.

温室气体排放量不断增长导致了地球温度持续升高.

The conclusions are that technology of foam producing gas with water withdrawal is an effective measure to achieve steady production of natural gas reservoir in Ordos Basin, and UT-6 foam stick is a better reagent.

认为泡沫排水采气工艺技术是实现鄂尔多斯盆地天然气藏气井稳产的有效措施，UT-6型泡沫棒在该地区是较好的药剂。

The land subsidence in China can be divided into two types: ( 1) the subsidence mainly caused by excessive groundwater withdrawal; ( 2) the subsidence caused by groundwater, oil, gas and warm groundwater withdrawal, and superposing on the neotectonic movement.

地面沉降主要有（1）由过量开采地下水引起的和（2）在新构造活动构造沉降的基础上，由开采地下水、油气、地下热水形成的地面沉降两种类型。

Cylinders can be supplied with standard valves for gas withdrawal or with siphon tubes connected internally to the valves for liquid withdrawal.

钢瓶可以配有用于气体提取的标准阀门或在内部连接到阀门的用于液体提取的虹吸管。
