针对塔河油田奥陶系碳酸盐岩缝洞型油藏储层特点,以及在压井方法、完井测试管柱设计和换装井口方法等方面存在的井控问题,创新换装井口新工艺,引进井控配套新工具.根据奥陶系油藏储层规模大小、流体性质,给出了适合塔河油田奥陶系复杂油气藏压井的新方法,设计出了适合奥陶系油藏不同油质、不同气油比和满足后期地质要求的常规完井测试管柱体系.

According to the features of carbonate fractured-vuggy reservoirs in Ordovician in the Tahe Oilfield and the well-controlling problems such as killing methods, completion testing string designs and wellhead-dressing methods, new techniques were innovated for wellhead-dressing and new tools for well-controlling were introduced. In view of the reservoir size and fluid properties of Ordovician, a new method suitable for killing the Ordovician complex reservoirs in the Tahe Oilfield was proposed, and a conventional completion testing string system was designed, which could deal with the Ordovician reservoirs with different oil properties and different gas/oil ratios.
