摘要
潞安矿区煤层气井井网布置采用350m×250m,根据区内两口试验井LA-016、LA-019裂缝实时监测技术取得的压裂裂缝半径、裂缝方位、裂缝影响高度,验证了井网布置的科学性和合理性,结合煤储层特征、区内构造、水文地质条件、煤层气后期开发与利用等因素,确定了在潞安矿区进行井网布置方法和原则,并结合实际情况来逐步完善,使其更具实用性。
350m×250 well pattern is used in CBM wells in Luan mining area. According to two testing wells LA-016 and LA-019 hydraulic fracturing fracture radius, orientation and height of influence data from fracture real-time monitoring, have validated the scientificity and rationality of the well pattern layout. Combined with factors of coal reservoir characteristics, geological structure, hydrogeological condition, CBM later stage exploitation and utilization, have determined well pattern layout method and principle, according to practical situation made it more practicable.
