古潜山由于古地形长期经受风化、剥蚀和地下水的溶滤作用,下伏岩层尤其是碳酸岩的孔隙度和渗透率大大增加,可形成大的裂隙或溶洞,地层喷、漏情况严重,作业施工难度大,井控安全要求高。根据埕岛潜山油藏具有高产、高压、喷漏严重的实际,通过选用合理的压井作业手段、完善的完井工艺,以实现海上安全环保生产。 Because of the long-term weathering, erosion and groundwater leaching of buried hills, the porosity and permeability of the underlying rock formations, especially carbonate rocks, have greatly increased, resulting in large fractures or caves, serious formation spray and drainage problems, and operations Construction is difficult, well-controlled safety requirements. According to the fact that Qindao buried hill reservoirs have high yield, high pressure and serious gushing leakage, the well completion technology is selected through reasonable selection of well killing operations so as to realize safe and environmentally friendly production at sea.
