苏丹17区Abu Gabra地区处于东达尔富尔和南科尔多凡州交界的地区,属于穆格莱德盆地,主要油气层为上白垩统Darfur群,下白垩统Bantiu组,下白垩统Abu Gabra组。该区块井深、封固段长,易井塌,固井施工中易发生水泥浆漏失,使固井施工面临很大考验。本文从Abu Gabra地区已固两口井进行总结分析,对该地区今后固井具有借鉴意义。
The Abu Gabra region of Sultan 17 is located in the junction of East Darfur and South Kordofan and belongs to the Muglad Basin. The major oil and gas formations are Upper Cretaceous Darfur Group, Lower Cretaceous Bantiu Formation, Lower Cretaceous Abu Gabra group. The well is deep in the block, the length of the sealing section is long, the easy well collapses and cement slurry leakage easily occurs in cementing construction, which makes cementing construction facing a great challenge. This article summarizes and analyzes two wells that have been consolidated in Abu Gabra area, which will be of reference for future cementing in this area.
