潜入式人工裂缝实时监测技术在低渗透气井的应用

Application of Artificial Fracture Real Time Monitoring Technology with Borehole Seismic Receiver in Low Permeability Gas Well

为了定量分析、判断压裂后是否产生裂缝,产生裂缝的方位、长度、高度等,采用潜入式人工裂缝实时监测技术,通过对整个压裂过程进行实时监测,得到裂缝的产状、主应力方向等定量参数。该项技术成功地应用于低渗透榆林气田的2口井4井次作业,为评价气井压裂措施效果提供了可靠依据。

The fracturing stimulation is an important method to improve seepage condition in low permeability reservoir. In order to quantitatively analyze whether the fracture is produced or not, and to estimate its direction, length, height, etc. , an artificial fracture real time monitoring technology with borehole seismic receivers was adopted. and main stress direction were obtained through real The quantitative data of the fracture attitude time monitoring the fracturing process. The technology has been successfully used in two wells （four times） of Yulin low permeability gas field and provided reliable data for evaluating the fracturing effect of gas well.
