Gas flaring is illegal in Nigeria and has been for a couple of years.

油井气继续被燃烧就是因为那些在尼日利亚的公司可以在尼日利亚和他们自己的国家通过这样的方式侥幸操作。

Using horizontal wells is an effective way to avoid early gas breakthrough and water coning of reservoirs.

在带气顶的底水油藏开发中，气水锥进是目前面临的重要问题，水平井开发能够有效地避免油井过早见气和过早见水，而确定水平井最优垂向位置是获得最佳开发效果的关键。

After the research, it was found the W8 fault was a laminal gas cap inspissated pool.

在开发过程中，发现气体影响较大，有油井7口不能正常生产，经研究认为W8断块是层状气顶稠油油气藏。

The difference between the calculating results of gas-oil rate considering or neglecting casing gas is compared. It is demonstrated that bigger error will be caused without considering casing gas. When the pressure at the casing shoe is lower than the babble point pressure, there is a certain proportion relation between the easing gas production and the submergence pressure as well as the easing-tubing sectional area ratio.

针对放套管气生产油井，现场测试了多口油井的套管气量，比较了考虑套管气与忽略套管气对气油比计算结果的差异，证明忽略套管气产量会给气油比计算结果带来较大偏差。

For the gas-producing wells containing certain formation water, gas-water ratio is usually much higher than that of oil-producing wells.

对于含水气井，其气水比一般比油井高得多，而且水和油物性差异大，气水两相流液体滑脱严重。

The main applications are oil or gas transfer pipe; pipe for oil well bushing; transfer pipe for medium or low pressure water, gas, oil; pipe used in the structure of low and medium pressure boiler、engine boiler heat exchanger and condenser; pipe for construction、iron tower、frame structure、tubular pile、stanchion and other structures; pipe for mechanic、engine、automobile、apparatus and other mechanical accessories.

A new expansive agent, Expandant DB, is developed for use in oilwell cementing to prevent gas channelling and poor bond quality.

姚晓，邓敏，唐明述，DB 型油井水泥膨胀剂的研究油井水泥固有的收缩特性是诱发油气井气窜和造成水泥环胶结质量差的主要原因。

In the process of the oil and gas field's exploration, when the well contains a great amount of supercritical fluid such as CO2 and H2S, the well blowout, erosion, wax problem and scale problems will take place more frequently. In the process of drilling, when the supercritical fluid emerged by conventional natural gas changes in phase transition, the well blowout will happen.

在油气田的开发过程中，井筒内高含CO2、H2S的超临界态流体，加速油井管柱的腐蚀、结蜡、结垢、灾难性的突发事故的出现；在钻井过程中，气侵的超临界流体在环空相态变化将可能引发钻井井喷。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
