摘　　要：研究认为,低渗透油藏中流体主要呈非线性渗流流动。为了更准确地模拟这一过程,选用自研软件,低渗透油藏非线性渗流数值模拟一体化系统,对纯17块油藏的概念模型进行数值模拟计算。在利用该软件对不同井距的五点井网进行模拟计算时,采用水驱产能比这一指标进行对比分析,从而优选出合理井距。低渗透油藏生产井产能往往较低,需要进行生产井人工压裂。利用自研软件,对生产井人工压裂缝的导流能力和裂缝穿透率进行模拟计算,进而优选出合理的压裂缝导流能力和裂缝穿透率。Present thoretical study suggests that fluid flow is mainly non-linear flow in low-permeability.In order to more accurately simulate the process,this paper chooses self-writing softwave,the systm of non-linear flow numerical simulation(low-permeability reservior),to simulate concept models of chun 17 block reservoir.The paper makes use of water-drive productive ratio to optimize reasonable well spacing when simulating different well spacing of five pot wells.The individual well producing rate is often low in low-permeability reservoir,so we often need artificial fracturing.With the help of self-writing software,the paper simulates flow conductivity and fracture penetration coefficient of hydraulic fracture to optimizing these two parameters.And in the end,the paper can provides some development advice for chun 17 block reservoir.
