4)  foam drilling technique
泡沫钻进
1.
As a kind of perfect and advanced drilling technique, especially in arid area and leaky formation, foam drilling method is accepted by drilling industry in many other countries, but the high press air-compressor, which has disadvantages of high technical requirement,and hight price and operating cost, extremely limits use and generalization of foam drilling technique.
泡沫钻进技术是一种省水、高效、先进的钻探技术方法,特别是在干旱缺水地区和漏失地层效果显著,并已被各国钻探行业所认可,但是其主要配套设备高压空压机却因技术要求高,价格昂贵,使用费用大,交通不便地区运输困难等缺陷,严重限制了泡沫钻进技术的推广和使用;而一套水泵泡沫增压装置就完全克服了上述缺陷,有力地推动了泡沫钻进技术的发展;为了进一步改进该增压装置的结构和提高其使用水平,组建了水泵泡沫增压装置实验台,对其增压性能和容积效率进行实验研究。

补充资料:去沫剂和消泡剂
分子式:
CAS号:

性质:又称去沫剂和消泡剂。系具有对泡沫相容性低和表面张力低的物质。用来控制、防止或消除各种泡沫,最广泛采用的是硅酮去泡剂,其他尚有以聚酰胺、植物油和硬脂酸制备的去泡剂。去泡剂与泡沫的气泡接触后,气泡膜的强度降低,使膜破裂,但去泡剂本身没有变化,继续与其他气泡接触,从而使泡沫消散。橡胶工业称脱泡剂。
