复合射孔及爆燃压裂动态测试数据分析
Data Analysis of Dynamic Testing of Downhole Hybrid Perforating and Deflagration
摘要
Abstract
To deeply study the working mechanism of hybrid perforator,the downhole dynamic data of 4 perforation/fracturing completion technique:conventional perforating,built-in type hybrid perforating,stimgun type perforating, and deflagration fracturing was obtained by using high-speed downhole tester, these data was analyzed combining with the operational process parameters. Data analysis show that the peak pressure of four kinds composite perforation is between 30 MPa~140 MPa;and pressure pulse duration varied widely because of different working mechanism:deflagration fracturing has the longest event time 305 ms, conventional perforating event time is just 0.272 ms;the downhole dynamic pressure effect of composite perforator mainly depends on the composite powder charge and blasting methods. These real datas provide an important reference for the establishment of the underground complex dynamic process model and enhancement of composite perforation performance.关键词
