分离式射孔压裂复合弹在油气井测试中的应用

APPLICATION OF SEPARABLE PERFORATING-FRACTURING COMBINED BULLET TO THE TEST OF OIL-GAS WELLS

为消除钻井、固井、完井射孔对油气层的污染,提高碳酸盐岩和砂岩油气层的油气产量。经过长期的研究、试验,提出将射孔和高能气体压裂合为一体,通过一次施工完成射孔和压裂两个工序。通过实例表明,该工艺不仅节约人力、物力及时间,而且能合理利用能源,是提高油气井产量的有力措施。

In order to eliminate the pollutions caused by drilling,well cementing,well completion and perforation in oil-gas beds and to enhance the oil-gas prodution of carbonate rock and sandstone reservoirs, through a long research and test,a new technique, by combining perforation with high-energy gas fracturing into a operating sequence,is presented. The example shows that the technique not only saves on manpower,material resources and time but also reasonally use energy resources,and is a forceful measure of enhancing oil-gas production.
