阳探1井是部署在渤海湾盆地冀中坳陷饶阳凹陷河间洼槽阳探1潜山构造上的一口风险预探井,属于一字号重点井。该井三开完钻井深5468m,采用Φ177.8mm尾管固井,封固段长达1650m。该井是华北油田在河间地区最深的一口井,静止温度高达182℃,顶部静止温度120℃,属于典型的高温大温差小间隙固井。针对该井的特殊井况,设计出符合满足施工要求的水泥浆体系,顺利完成本开次固井施工,为下一开钻井奠定了基础。
Yangxian-1 well is a risk pre-exploration well deployed on Yangzi 1 buried hill in Yanghe depression of Raoyang depression in the Jizhong Depression in the Bohai Bay Basin, belonging to a key well. The well opened three drilling depth of 5468m, the use of Φ177.8mm tail pipe cementing, sealing section up to 1650m. The well is the deepest well in the Hejian area of Huabei Oilfield. The temperature at rest is as high as 182 ℃ and the resting temperature at the top is 120 ℃. It is a typical high-temperature large-temperature small gap cementing. Aiming at the special well conditions of the well, a cement slurry system meeting the construction requirements was designed and the cementing construction of this opening was successfully completed, laying the foundation for the next drilling operation.
