压裂是吉林低渗透油田新区开发和老区稳产的主要增产措施,而压裂效果的好坏却受着诸多因素的影响。从分析影响因素入手,提出在压裂后的适当时期对人工裂缝进行处理,清除伤害裂缝的物质,恢复裂缝的导流能力,提高油井的产量,延长压裂的有效期。
Fracturing is the main stimulation for the development of new low-permeability oilfields in Jilin and the stable production in old areas. The fracturing effect is affected by many factors. Based on the analysis of influencing factors, it is proposed that the artificial fractures should be treated at an appropriate time after fracturing to remove the material that damages the fractures, restore the flow conductivity of fractures, increase the production of oil wells and extend the effective period of fracturing.
