【摘要】：辽河油田存在厚度达150m的巨厚超稠油油藏,应用SAGD技术开发取得了巨大的成就。目前,辽河油田的SAGD水平井完井管柱采用的主要是Φ177.8mm筛管,由于尺寸的限制,在一定程度上制约了油井产量的提高。为了进一步提高采油速度和最终采收率,使油田得到更加高效的开发,首次提出并实施了Φ244.5mm生产筛管钻完井工艺,与常规Φ177.8mm筛管相比较,其过流面积增加了58%。通过大尺寸井眼SAGD水平井井身结构设计、井眼轨道设计与轨迹控制、钻井液设计、完井管柱安全顺利下入等技术研究,实现了Φ244.5mm筛管完井的目的。现场应用3井次,单井日产油147t,日产水平是常规井的3倍。实践表明,大尺寸井眼SAGD水平井钻完井技术在开发超稠油油藏方面展现了良好的应用前景。
[Abstract]:There is a huge thick super heavy oil reservoir with a thickness of 150m in Liaohe Oilfield, which has made great achievements by using SAGD technology. At present, the main of the completion pipe column of the SAGD horizontal well in Liaohe Oilfield is the SAGD sieve tube. Due to the limitation of size, the production of oil well is restricted to a certain extent. In order to further improve the oil recovery speed and finally, the oil production speed and final result are further improved. The recovery has made the oil field more efficient, and first proposed and implemented the drilling and completion technology of the 244.5mm production sieve tube. Compared with the conventional 177.8mm sieve tube, the overflow area increased by 58%. through the design of the well body structure of the SAGD horizontal well, the trajectory design and trajectory control of the well, the design of the drilling fluid, and the safety and smooth of the completion pipe column. Down in technology research has realized the completion of the well completion of the 244.5mm sieve tube. 3 wells are used in the field, the daily oil production of a single well is 147t, and the daily production level is 3 times that of the conventional well. The practice shows that the SAGD horizontal well drilling and completion technology in large size wells shows a good application prospect in developing super heavy oil reservoirs.
