| 摘 要： | 复杂裂缝压裂工艺是针对致密油油藏储层改造提出的新技术。以新86井区致密泥晶云岩储层为研究对象进行复杂裂缝压裂技术研究和试验,从地层天然裂缝是否发育,储层的脆性指数是否符合产生网络裂缝的条件,水平应力系数差是否满足形成缝网条件等方面,对其产生缝网可行性进行了分析论证。进行现场试验,并从影响措施效果的地质因素着手,对比工艺差异,进一步对复杂裂缝压裂技术的适用性进行分析,认为针对低渗透致密油藏,复杂裂缝压裂工艺的改造模式更有利于提高挖潜能力。

| Abstract: | Complex fracturing process is a new technology aiming to reservoir reform of tight oil reservoir. Focusing on Xin 86 Wellblock featuring compact mud--crystal dolomite, this paper studies the new technology and demon- strates the feasibility of fissure net formation considering if layer＇s natural fracture is well--developed, if reservoir brittleness index fits for the condition for fissure net formation and if horizontal stress coefficient difference meets the condition for it. Field test believes that reconstruction mode of complex fracturing technology is better for improving oil production in compact reservoir with low permeability. |
