The development of radial horizontal well drilling technology was under the studies on swirling jet theory and rock failure mechanism.
旋转射流理论和破岩机理研究，研制了径向水平钻井技术。
Radial horizontal well is the most complicated one in horizontal well series, it has a major horizontal section and one or several branch sections.
辐向水平井是水平井系列中的高难度井，它除了有一段水平井段外，还有另外一条或多条分支井段。

该技术可以在同一煤层气勘探井内，在不同煤层内完成多个径向水平钻孔。
The results indicate that infinite-conductivity horizontal well transient pressure is influenced by variable flux, but it doesn't appear early well-bore radial flow characteristic.
计算表明，无限导流水平井压力动态早期受流率分布变化影响，并不出现井筒径向流特征。
