【摘要】 深入了解水力压裂裂缝的几何形态和延伸情况有助于改善低渗油气藏压裂增产作业效果,改善油气井产能并提高油气采收率。应用地震方法对水力压裂裂缝进行监测和描述已经有多年了,而新的地震硬件和处理技术的出现使得这类监测更加有效、可靠。更多还原

【Abstract】 Microseism method can provide key information about hydraulic fractures.Knowing the geometry and stretching of hydraulic fractures can help to improve the fracturing effect of yield increase in low-permeabihty reservoirs and to improve the rate of oil or gas recovery.This pa- per introduces a method to monitor hydraulic fracturing.The application effect is proved through some examples in the United States and Japan.更多还原
