在射箭河构造的射1井采用φ311钻头钻至井深4478m,井下显示段多达17个漏,气、水层同存段,尤以漏和出盐水为主要矛盾。在钻井中,因盐水层频现、井漏和出盐水未间断,曾堵漏作业14次其中桥浆堵漏11次,微珠水泥堵漏3次,堵漏结果只是维持钻进。累计漏失井浆1743.5m~3,出盐水632.9m~3。分析主要漏层为3362～3379m,2899.30～2901m,4130.70～4132.40m,主要盐水层为3789.20～3792.20m。1992年6月钻至固井深度4478m~3,井浆密度1.50g/cm~3,粘度50s。循环
The shot 1 well constructed at Archery River is drilled with a φ311 drill bit to a depth of 4478 m. As many as 17 leakages, gas and water layers are co-located in the well below the well, with the main contradictions of leakage and saltwater. In the drilling, due to the frequent occurrence of the brine layer, there was no leakage of salt water and no leakage of salt water. There were 14 plugging operations in which the bridging plugging occurred 11 times and the bead cement plugged up three times. The plugging result was only to maintain drilling. Accumulated loss of slurry 1743.5m ~ 3, brine 632.9m ~ 3. The main leakage layers are 3362 ~ 3379m, 2899.30 ~ 2901m, 4130.70 ~ 4132.40m, and the main aquifer is 3789.20 ~ 3792.20m. June 1992 Drilling to the depth of 4478m ~ 3, the well density 1.50g / cm ~ 3, viscosity 50s. cycle
