Application of PVA1788 film-forming system solid-free drilling fluid in Well Guiliudi-1

摘要: 桂柳地1井为广西柳州市鱼峰区雒容镇区块页岩气地质调查井，设计井深2350 m，钻遇水敏性地层等复杂地层。为了提高无固相冲洗液在页岩气复杂地层深孔钻进中维持孔壁稳定的能力，在PVA1788体系无固相冲洗液的基础上，添加成膜A剂、封堵剂GFD-1等处理剂。根据冲洗液试验及现场应用，成膜A剂具有降失水功能，不影响冲洗液的润滑性能，对粘度影响不明显，该PVA1788成膜体系无固相冲洗液滤失量较低，封堵裂隙效果好，减弱了地层水化膨胀，提高了成膜抑制防塌能力，满足了桂柳地1井深孔复杂地层维护孔壁稳定、安全钻进的需要。对类似复杂地层无固相冲洗液的推广应用具有参考价值。Abstract: Well Guiliudi-1 is a shale gas geological survey well in Luorong town block, Yufeng district, Liuzhou City, Guangxi province. The designed well depth is 2350m, and complex formations such as water sensitive strata are encountered during drilling. In order to improve the ability of solid-free drilling fluid to maintain the stability of hole walls in deep hole drilling in complex formation of shale gas geological survey， drilling fluid treatment agents such as the film-forming agent A and the plugging agent GFD-1 were added to the solid-free flushing fluid of PVA1788 system. Test and field application showed that the film-forming agent A had the function of reducing water loss without affecting the lubrication performance of the flushing fluid， or any obvious effect on the viscosity. The PVA1788 film-forming system solid-free drilling fluid has low filtration loss， good fracture sealing effect， reduces formation hydration expansion， and improves sloughing inhibition and prevention ability with film-forming； meeting the needs of maintaining the stability of the hole wall and safe drilling in the deep hole and complex formation. This paper has reference value for the popularization and application of solid-free drilling fluid in similar complex formations.
