本文通过应用DQHY软件对裂缝长度、方向及导流能力参数进行模拟,从而得到裂缝对气藏增产效果的规律,为制定最优的压裂方案,达到最优的增产效果提供了依据,但是在开发过程中,虽然裂缝对低渗透气田的采收率提高是很大的,但是影响它的因素不是单方面的,我们不但要看到它的增产效果,同时即要对压裂成本进行综合考虑,从而指定最佳压裂方案。
In this paper, by using DQHY software to simulate the parameters of crack length, direction and flow conductivity, the law of increasing production of fractures on gas reservoirs is obtained, which provides the basis for making the optimal fracturing plan and achieving the optimal stimulation effect. However, In the process of development, although the fracturing is of great significance to the recovery of low-permeability gas fields, the factors affecting it are not unilateral. We should not only see its stimulation effect, but also consider the fracturing cost comprehensively , To specify the best fracturing scheme.
