随着中国海油发现的低孔(孔隙度)、低渗(渗透率)油气藏增加,为实现在确保一定的孔密(射孔密度)和不实施压裂作业的情况下,有效地增加射孔器的穿深和孔径,提升低孔低渗油气井的产能和低孔低渗边际油气田的开发效益,上海分公司、中海油服与川南石油机械厂联合开展了“低孔低渗油气井超深穿透射孔工艺研究”。
With the increase of low porosity (porosity) and low permeability (permeability) reservoirs discovered by CNOOC, in order to achieve effective increase in ensuring certain hole density (perforation density) and not performing fracturing work, Perforator piercing depth and pore size to enhance the productivity of low porosity and low permeability oil and gas wells and development benefits of low porosity and low permeability marginal oil and gas fields, Shanghai Branch, COSL and South China Petroleum Machinery Plant jointly launched the “low porosity and low permeability oil and gas Well ultra-deep penetration perforating process ”.
