一、井孔概况苏03井地理座标为北纬33°58′,东经117°57′。该井井深449.28米,第四系覆盖层厚110.45米,为套管封闭。覆盖层下为震旦系白云岩和白云质灰岩,溶洞裂隙发育。钻孔穿过两段断层角砾岩。第一段147.46米—204.40米,为主要富水段,单位涌水量为4.26米/米·秒。第二段331,30米—338.10米,在360—366.40米处岩石破碎,裂隙发育,裂隙面见有断层擦痕。该井孔所揭露的溶洞、角砾岩和裂隙井孔特征,说明其为岩溶裂隙承压水,富水性能和径流、承压条件良好,该井对远大震,在其发生之前能记录到锯齿状和小波纹状的波形(另文探讨)
First, the well profile Su 03 well coordinates as north latitude 33 ° 58 ’, longitude 117 ° 57’. The well depth of 449.28 meters, Quaternary cover thickness of 110.45 meters, for the casing closed. Sinian dolostones and dolomitic limestones are under the overburden, and the fissures in the cave are developed. Drilled through two fault breccias. The first paragraph of 147.46 meters -204.40 meters, as the main water-rich section, the unit of water inflow of 4.26 m / m · sec. The second paragraph 331,30 meters -338.10 meters at 360-366.40 meters rock broken, fracture development, fracture surface see fault scar. The characteristics of karst caves, breccias and fractured bores exposed by the boreholes indicate that they are under pressure, water-rich and runoff in karst fissures with good pressure bearing conditions. Before the occurrence of this great earthquake, the well could record Jagged and small corrugated waveforms (another discussion)
