摘要
针对当前油藏工程界普遍存在的油层有效厚度对油藏开发效果是有影响的认识未给出理论证实的问题,从单相不可压缩流体、单相弱可压缩流体渗流入手,应用油藏渗流力学原理及油藏数值模拟方法,明晰了油藏开发效果的影响因素,并应用油藏数值模拟软件ECLIPSE进行了验证.理论研究与数值模拟研究结果表明,油层有效厚度对油藏开发效果都是有影响的,且油层有效厚度越厚,其对油藏开发效果影响越大.油层有效厚度是通过油藏流体重力作用来影响油藏开发效果的.在油藏开发效果影响规律研究中,理论研究和数值模拟方法各有优缺点,理论研究方法应注意相关理论适用条件,数值模拟方法应规避影响其计算精度的网格数、油水井生产制度等参数.
In view of the current reservoir effective thickness of reservoir engineering is widespread understanding of reservoir development effect is not given theory problems, using the modern mechanics of fluids flow in oil reservoir, this paper deduces the Single phase incompressible fluid and single-phase weakly compressible fluid reservoir development effect formula that clear the effect factors of reservoir development. At the same time, the new conclusion is verified using reservoir numerical simulation software（ECLIPSE）. The study indicate that the oil layer effective thickness should have effect on reservoir development effect, and The thicker the oil layer effective thickness, the greater the reservoir development effects, and the oil layer effective thickness affects the reservoir development effect through reservoir fluid gravity. Theoretical research and numerical simulation method has its advantages and disadvantages, related theory applicable conditions should be paid attention to theoretical research method, numerical simulation method should avoid affect the calculation accuracy of grid number, production system parameters such as oil and water Wells.
