natural gas migration的意思|示意

The natural gas in the Ordovician of the central-eastern part of the basin is divided into four migration fields by using the data of carbon isotopic ratio in methane.

利用甲烷碳同位素资料将盆地中东部奥陶系天然气划分出四个运移场。

So that it can be used as an indication of natural gas migration to determine lateral migration distance and direction.

因此，它可作为气运移的指标，判断横向运移的距离和方向。

And the large ancient buried platform is the beneficial zone for the migration and accumulation of natural gas, controlling the shape and scope of the gas reservoir.

大型古潜台是天然气运聚的有利区带，它控制了气藏的形态和分布范围。

There are mainly 4 key parameters of natural gas resource evaluation, including gas production rate, migration-accumulation coefficient, play evaluation parameters, and recovery rate.

天然气资源评价重点参数主要包括产气率、运聚系数、区带评价参数与可采系数等4项。

Meanwhile, a set of natural gas geological theory has been established including gas source, migration, accumulation and storage.

同时，初步形成了一套包括天然气生成，运移，聚集，保存的地质理论。

The model is based on the unique of natural gas in its migration, accumulation and preservation.

这一模型是根据天然气在运移、聚集和保存过程中的特殊性建立的。
