塔里木油田开发事业部创新使用国产复合超深穿透射孔技术,增强地层渗流特性和渗流面积,截至5月12日,有14口油井实现增产,日增油146 t,累计增油7 200 t。目前,塔里木油田油气开发面临着低渗透、低孔隙度、高致密油气藏较差储层与近井地带污染严重的储层,采用常规射孔补孔工艺作业无法达到增油、增注的目的。部分水平井因钻井井眼轨迹偏差,导致常规射孔工艺因射孔穿透距离短,无法穿透较长泥岩隔层。
Tarim Oilfield Development Division innovative use of domestic composite ultra-deep penetrating perforating technology to enhance the formation of seepage characteristics and seepage area, as of May 12, 14 wells to increase production, increasing oil 146 t, the cumulative oil 7200 t . Currently, the oil and gas development in the Tarim Oilfield is facing the serious pollution of reservoirs with low permeability, low porosity and high density in tight reservoirs and near-wellbores. The purpose of using conventional perforation and recharging can not achieve oil increase and increase injection . Some horizontal wells due to deviation of the wellbore trajectory, resulting in the conventional perforation process perforation due to the short distance, unable to penetrate the longer mudstone compartment.
