查询词典 actual gas

This paper combines with pipeline delivery of our countrys actual conditions and other methods of detection and location. To the leakage characteristic of the fault to the long-distance natural gas pipeline, a method is raised, which is on the basis of wavelet and negative-pressure-wave to detect the leakage and locate. Jobs in this paper are as follows:Multi-resolution decomposition and reconstruction of wavelet transform is utilized to filter the noises, which the leakage brings the noises of negative-pressure-wave. The research is worked in the wavelet and wavelet packet filter. The wavelet transform have a fast and accurate recognition capability to signal singularity. This paper chooses wavelet technology to catch the break point of pressure signal.

本文结合我国管道输送的实际情况和目前现有的各种泄漏检测与定位方法，针对天然气长输管线泄漏故障的特点，提出了基于小波分析和负压波相结合的方法检测泄漏并定位，其中主要进行了以下几个方面的工作：利用小波变换的多分辨率分解和重构技术，对采集到的管道发生泄漏时产生的负压波信号进行降噪处理，并对小波及小波包优化的降噪效果进行对比性研究；利用小波变换技术对信号奇异点的快速、准确的识别能力，捕捉负压波信号的突变点，从而判断是否有泄漏发生。

There are many calculating methods for dynamic gas reserves. Among them, pressure build-up method and pressure differential curve method are commonly used. This is due to their advantages and actual proof by field tests in application degree. But all of them have their own constraining conditions, so it is difficult to say which one is more reliable.

天然气动态储量的计算方法很多，其中压力恢复法和压差曲线法是计算气井动态储量的常用方法，它们有很多优点，其应用程度已被矿场实际证实，但它们都有各自限制的应用条件，很难说明哪种方法计算更可靠。

Theoretical calculation shows the anomaly of reservoir tidal gravity is measured at μGal level, while the measured data shows the observation error of such tidal gravity at 10-μGal level. This indicates that the data noise may well disguise real anomalies, and therefore that the lack of measured anomaly data does not necessarily equate to the lack of oil and gas reservoir underneath. The actual observed tidal gravity anomaly can reach tens of μGal. Though it is more than three times the observation error, we can not attribute it to the reservoir-induced tidal gravity anomaly.

理论计算表明，油藏潮汐重力异常在微伽量级，而实际资料表明潮汐重力的观测误差为10 μGal量级，油藏潮汐重力异常可能会被噪声淹没，所以没有观测到潮汐重力异常不等于地下没有油气；实际观测的潮汐重力异常可达数十μGal，即使超过观测误差的3倍，也不能将它直接归因于油藏产生的潮汐重力异常。
