浅谈致密油藏直井体积压裂储层改造体积的影响因素

Shallow Talk about the Influence Factors of the Volume of the Fractured Reservoir in the Tight Reservoir

致密油是一种自生自储的非常规油气资源。致密油储层因为致密、渗透率低,所以储层基质向裂缝的供油能力差,仅仅依靠单一的压裂主裂缝方法很难达到增产的效果,体积改造要形成裂缝网络,才能在最短距离内让流体基质到裂缝渗流,所以致密油储层的改造要在三维的方向形成裂缝网络才能全面改造,即体积压裂。针对三叠系致密油储层的特点建立缝网模型,然后对比体积压裂与常规压裂的效果,得出体积压裂对储层改造体积的影响。

Tight oil is a kind of unconventional oil and gas resources in the self-storage. Because of tight oil reservoir and low permeability, it is difficult to achieve the effect of.increasing yield by single fracturing method, which can be fonaed in the shortest distance, so that the transformation of tight oil reservoir can be transformed, the volume is fracturing. Aiming at the characteristics of Triassic tight oil reservoir establishment of fracture network model, then contrast volume fracturing and conventional fracturing effect, it is concluded that the volume fracturing effect of the reconstructed volume of reservoir.
