高能气体压裂技术又称可控脉冲压裂、爆燃压裂。这项技术最早起源于美国 ,194 6年进行了首次试验。该技术在美国、前苏联、加拿大等国已经得到了广泛的应用。高能气体压裂技术是一种经济可行的技术 ,不受井底条件的限制 ,我国的大庆、长庆、华北、辽河、四川、吐哈等油田都试用过此项技术 ,取得了较好的效果。井底发生爆燃后 ,造缝长度可达 2～ 10m ,能够有效地提高产能。近 10年来 ,我国探明的低孔低渗油层储量约占全国探明储量的一半 ,如何提高其采收率是我国石油工业亟待解决的问题。所介绍的新技术有助于我国低孔低渗油田的开发。
High-energy gas fracturing technology, also known as controlled pulse fracturing, deflagration fracturing. The earliest originated in the United States, the first experiment was conducted in 1964. The technology in the United States, the former Soviet Union, Canada and other countries have been widely used. High-energy gas fracturing technology is an economically feasible technology, not limited by the conditions of the bottom hole, our country Daqing, Changqing, North China, Liaohe, Sichuan, Turpan and other fields have tried this technology and achieved better effect. After blasting at the bottom of the well, the length of the stitching can reach 2 ~ 10m, which can effectively increase the production capacity. In the past 10 years, the proven reserves of low porosity and permeability oil reservoirs in our country account for about half of the national proven reserves. How to increase its oil recovery is an urgent problem to be solved in China’s oil industry. The new technology introduced contributes to the development of low porosity and permeability oilfield in our country.
