水平井底水锥进临界产量计算

CALCULATION ON THE CRITICAL PRODUCTION OF BOTTOM WATER CONING IN HORIZONTAL WELL

QHD32 - 6油田A2 6水平井油层下有一底水 ,为了确定合理的投产产量 ,需要确定底水锥进的临界产量值。针对QHD32 - 6油田A2 6水平井的具体参数 ,分析了底水油藏水平井水锥的形成机理 ,分析了计算底水锥进临界产量的几种数学模型 ,根据油层实际情况选定了其中的两种模型并通过计算对垂向渗透率、油水密度差、水平井位置等参数对临界产量的影响进行了分析 ,对指导A2

The payzone of A26 horizontal well in QHD32-6 oil field has a bottom water. In order to determine the suitable commissioning production, the critical production of bottom water coning must be studied. According to the actual parameters of A26 horizontal well in QHD32-6 oil field, the mechanism of bottom water coning in horizontal well was analyzed, and several mathematical models for calculating the critical production of bottom water coning was established. and two mathematical models were selected and analyzed for critical production on the affection of parameters such as vertical permeability, density difference between water and oil, well position and so on, which are very important to guide the commissioning design of the well.
