摘要:
射孔密度、孔眼直径和射孔相位角等射孔参数的优化对于海上稠油热采水平井高效、稳定的生产有着重要的作用。以水平井射孔完井产能预测模型和射孔后热采井套管强度损失计算模型为理论基础,通过数值计算对水平井相关射孔参数进行了敏感性分析; 在保证套管强度损失在安全生产允许范围内,利用三因素四水平正交试验方法对现场生产井常规射孔参数进行优选,使热采井能够在长期稳定生产的前提下实现产能的最大化。优选分析结果表明,孔径18 mm、孔密60孔/m、相位45°等射孔参数组合可确保热采井生命周期内套管完整,并获得较高的油井产能。本文研究结果对海上稠油热采水平井套管射孔参数的优选具有借鉴意义
Abstract:
The optimization of perforation parameters, such as shot density, hole diameter and phase angle, is very important to the efficient and stable production of offshore heavy oil thermal recovery horizontal wells. In this paper, based on the theoretical basis of productivity prediction model for the perforation completion of horizontal wells and the strength loss calculation model for casings in thermal recovery wells after perforation, sensitivity analysis on relevant perforation parameters of horizontal wells is carried out through numerical calculation. On the premise of ensuring the casing strength loss within the allowable range for safe production, the conventional perforation parameters of field production wells are optimized by using the “three-factor” and “four-level” orthogonal test method to enable thermal production wells to achieve the maximum production capacity and long-term stable production. The result of optimization analysis shows that the perforation parameter combination of hole diameter 18 mm, shot density 60 holes/m and perforation phase angle 45° can ensure the integrity of casing in the life cycle of thermal production well and obtain high productivity. The results of study provide reference for selecting the casing perforating parameters of offshore heavy oil thermal recovery horizontal wells
