井下微地震裂缝测试技术在长庆油田的应用
|
摘要
裂缝方位和几何尺寸决定了井网的部署、射孔的方位、压裂设计的优化等,直接影响着低渗透油田开发的好坏。长庆油田采用井下微地震技术进一步认识到水力裂缝延伸的复杂性,明确了压裂裂缝真实延伸情况,在指导油田开发中的井网部署、压裂优化设计、压裂后的效果评估方面将发挥重要作用。
The orientation and geometrical size of the fracture not only makes a decisive role on well spacing,perforation azimuth,and fracturing design optimization,etc.But also affects the development of the low permeability oilfield. By applying micro-seismic testing tech in Changqing oilfield, the complex of the hydraulic fracture extension is understood further and the reliable extension status of the fracture can be definitude and it will also plays an very important role in the field development on well spacing, fracturing design optimization, and fracturing assessment.
