| 摘 要： | 吐玉克油田是在吐哈盆地亲开发的一个油田，以裂缝－孔隙性储层为主，根据其储特征，开展了保护油气层钻井液的实验研究，未加暂堵剂的原用聚磺钻井液对吐玉克油田裂缝－孔隙性储的损害十分严重，损害后储的渗透率不足原始渗透率的3％，将球形颗粒暂堵剂（XCB5－1），纤维状暂堵剂（LF－1）和可变形颗粒暂堵剂（EP－1）复配使用，能够达到“堵得稳”和“易反排”的技术要求，现场应用取得了十分显著的效果。

| Abstract: | Tuyuke Oilfield is a newly developed one located in Tuha Basin, behaving as fracture-pore reservoir. Study on drilling fluid technology is performed based on the formation characteristic and the matching bridging agents are optimized. Lab tests show the fluid damage the formation severely without temporary plugging agents with final permeability less than 3% of the original data, but with XCB5-1, LF-1 and EP-1 compounded, the fluid meets the requirements of stable plugging and easy back-blow Field using is successful. |
