| 摘 要： | 针对低渗透油田单井产量低、注水压力高、增产增注措施受限制的实际情况,为进一步拓展增产增注措施思路,在某油田优选2个试验井组开展水力深穿透缩短驱替距离试验.根据技术原理,建立喷射孔眼在油层内长度的数学模型,综合考虑地层倾角、井斜角及射孔方向的影响,对软管推进轨迹进行了理论分析.在此基础上,确定试验井施工参数.现场试验表明...

| Abstract: | Aiming at the situation of low oil rate,high water injection pressure and limited stimulation measures for low-permeability reservoirs and in order to expand the ideal of stimulation,two well-groups in one of field were properly chosen and the hydraulic deep-penetration tests were conduced to shorten the displacement distance.Starting from the technical principle,this paper established the mechanics by mathematically modeling the distance of jetting within the reservoir.The influential factors like stratigraphic dip,deviation angle and perforation direction were considered.Meanwhile,it theoretically analyzed the hose advancing trackway.Based on this,the operation parameters of tested wells were determined.Field experiment shows that this effective way can realize the oriented stimulation of reservoirs. |
