用微地震技术评价姬塬油田体积压裂的效果
The application of micro-seismic monitoring and evaluation technology to evolution of volume fracturing effect in the Jiyuan oilfield
摘要
Abstract
Micro-seismic monitoring technology is an important means to evaluate the fracturing effect of low permeability reservoir and to guide the development of fine water injection in oil reservoir.Through the observation and analysis of micro-seismic events produced by fracturing,the location,size,flow conductivity,geometric shape and local fracture distribution regularity of fractures can be obtained.Wangpanshan Chang 8 reservoir of the Jiyuan oilfield is characterized by low porosity,low permeability and low voltage,and hence production will decrease soon after the conventional fracturing production is conducted for a period.In recent years researchers have carried out mixed water volume fracturing and implemented the micro-seismic monitoring.The monitoring of Lu 58-54 well mixed water volume fracturing results shows that the long slit produced is up to 315.97 m,the seam width is 104 m,the fracture height is about 58 m,the affected volume is about 24.48 million m3,and the direction is NE 19.5°.The fracturing has caused the reservoir layer cracks to open and drainage radius to increase,thus increasing the amount of single well production.The effect is very obvious,and the results obtained by the authors lay a solid foundation for further fine development of the reservoir.关键词
