摘要
针对渝东北地区的地震地质特征,在城口页岩气勘查区对城页1井区进行了地面微地震监测试验。环形布设32个监测台站,台站排列直径与页岩气压裂目的层深度相当。采用三分量速度检波器,钻浅孔埋置,其中部分检波器埋深30 m。监测拾取到有效信号74个,储层改造体积1. 93×10~7m^3,取得了较好的改造效果。试验结果表明,在该地区运用地面微地震监测技术是可行的。
According to the seismic geological characteristics of northeastern Chongqing,surface microseismic monitoring test is carried out in ChengYe 1 well,Chengkou Shale Gas Exploration Area.Thirty-two monitoring stations are set up in the ring,and the arrangement diameter of the stations is similar to the depth of the fracturing target formation of shale gas.The three-component velocity geophones are used to monitor the microseismic wave in shallow holes,some of which are 30 meters deep.74 effective signals are picked up and the volume of reservoir reconstruction is 1.93×10^7m^3,which has achieved good results.The test results show that it is feasible to use ground microseismic monitoring technology in this area.
