长2油层物性较差,常规射孔后不经改造基本无自然产能。本文针对麻黄山长2油藏底水发育,受所处油藏部位的影响,油水接触关系复杂,对该井进行压裂优化设计,从而改变油井底部的渗流阻力,提高油气在井底流动效率。根据长2的地质特点和岩石力学性质,对长2的耿108井进行压裂设计,利用PT压裂软件进行模拟,设计出合理的泵注压裂程序,压裂液量等参数,从而达到设计的裂缝尺寸,提高油气产量。
Long 2 reservoir physical properties are poor, after conventional perforation basically no non-natural production capacity. In this paper, the development of bottom water in Chang 2 reservoir of Mahuangshan Mountains is affected by the reservoir location, and the oil-water contact relationship is complex. The fracturing optimization design of the well changes the seepage resistance at the bottom of the well and enhances the oil-gas flow efficiency at the bottom hole . According to the geological characteristics of Chang 2 and the mechanical properties of rock, the fracturing design of Well 2 108 of Chang 2 was carried out and the simulation was carried out by using PT fracturing software to design a reasonable pump-injection fracturing program and fracturing fluid volume and other parameters to achieve Crack size design, increase oil and gas production.
