高能气体压裂是解决长庆低渗透油气层解堵的一项简便易行的技术手段。由于火药燃烧随压力增高呈指数增加趋势,装药量受到极大限制。火药燃烧产生大量的CO气体也是一个潜在的危险因素。国外特别是乌克兰等国家都在研究一种新型化学反应气动力热解堵的新技术。根据国外研究的思路,笔者用铝粉、NaOH、NH4NO3甲醛等数种化学物质组配进行了实验室试验研究。以期得到一种新的化学反应气动力热解堵的技术途径。
High-energy gas fracturing is a simple and easy technical means to solve the plugging in Changqing low-permeability oil and gas formation. As the burning of powder increases exponentially with increasing pressure, the loading capacity is greatly limited. The burning of gunpowder to generate large amounts of CO gas is also a potential risk factor. Abroad, especially Ukraine and other countries are studying a new type of chemical reaction aerodynamic pyrolysis plugging new technology. According to foreign research ideas, the author used aluminum powder, NaOH, NH4NO3 formaldehyde and other chemical compounds with a group of laboratory experiments and studies. In order to get a new chemical reaction aerodynamic pyrolysis plugging technology.
