__NOTOC__ <small-title />

由引擎发动的旋喷是一种[[Jetting - general|喷射技术]]，它使用引擎旋转钻柱并将泥浆抽出。现使用多种规格的由引擎发动的旋转钻井设备。在发展中国家使用的商业钻井设备为Lone Star 100、PAT Drill 201和 Deep Rock Hydra；还有很多其他类型。

虽然人们预计使用引擎比使用人工的优势更大，但就旋喷而言，其实两者用时相同，钻取的深度也相同。由引擎发动的技术只是在人类工程学方面的表现更胜一筹。

===Construction, operations and maintenance建造、运作和维护===A self made engine-driven rotary rig is not very difficult to make, although drill bits, drill pipes and engine may have to be specially imported.自己制作由引擎发动的旋转钻井设备并不难，但是钻头、钻管和引擎可能需要专门进口。

===Costs费用===The price of these rigs depends and varies between US$ 3000 and US$ 5000. 这些钻井设备的造价在3000美元到5000美元之间。

===Field experiences实地经验===Engine operated rotary jetting is mainly used in Thailand, Laos, Cambodia, Chad, Niger, Nigeria, Burkina Faso, Tanzania, Mozambique, Zambia, Mauritania, Madagascar and Nicaragua.使用由引擎发动的旋转喷射的国家主要有泰国、老挝、柬埔寨、乍得、尼日尔、尼日利亚、布基纳法索、坦桑尼亚、莫桑比克、赞比亚、毛里塔尼亚、马达加斯加和尼加拉瓜。
