| 摘 要： | 微地震监测技术是页岩气开采过程中对页岩气储层压裂效果评价和指导压裂过程的重要手段,可通过观察、分析压裂过程中诱发微地震事件,获取压裂裂缝参数、导流能力、裂缝展布发育方向等信息。中牟区块牟页1井具有低孔、低渗储层特征,对含气层段的三层储层,采用大排量水力压裂施工,进行地面微地震监测、井中微破裂成像技术压裂监测及微地震监测;牟页1井监测压裂结果显示为缝长251～496m,缝宽120～252m,改造体积约为237.5×104～387.7×104 m3,方位角64°～80°。压裂实施使储层裂缝开启含气层段得到改造,指导了实时压裂和压裂效果评价。

| Abstract: | Microseismic monitoring technology is an important means to evaluate the fracturing effect of shale gas reservoirs and to guide the fracturing process. By observing and analyzing the microseismic events induced in the fracturing process, the fracturing parameters, conductivity, the development azimuth of the fractures and other information are obtained. The Mouye No. 1 well in the reservoir area of Zhongmou block has the following characteristics:low porosity and low permeability. The three layer reservoir of gas zone is conducted large volume hydraulic fracturing operation and the fracturing was monitored with micro-seismic technique at the ground surface and the micro-fracture imaging technique and micro-seismic technique in the well. The result is that the fracture is 251~496 m long and 120~252 m wide, the reworked volume is about 237.5~387.7 million m3, azimuth is 64°~80°. Implement of the hydraulic fracturing opens fractures in reservoir and reworks the gas zone so as to guide the real-time fracturing and evaluate fracturing effects. |
