摘要/Abstract

摘要： 水平井技术作为提高油气田开发效益的关键手段,其产能预测精度直接关系到井网部署与开发方案设计的合理性。但现有模型常忽略实际井轨迹起伏及油水两相渗流特征,导致预测偏差较大。为此,基于当量井径原理和压降叠加理论,结合油水两相拟压力函数,建立考虑真实井轨迹的水平井油水两相产能预测模型。通过离散井段、压降叠加计算和相渗表征,实现了产液剖面的精细预测。研究结果表明:水平井的沿程日产油量分布大体呈“U”形,受实际井轨迹影响日产油量存在波动;随着水平井长度的增加,日产油量缓慢增加;水平井各段日产油量与渗透率正相关,穿过高渗地层有助于提高产能。相渗曲线形态对日产油量和日产水量有显著影响,低含水饱和度下相对渗透率曲线呈水相凹型时,水平井具有最佳产油性能。该研究为优化水平井设计和提高油井产能提供了理论依据。

Abstract: With the growth of global energy demand, horizontal well technology has become an important means for oil and gas field development. Based on the equivalent wellbore radius principle and pressure drop superposition theory, combined with the oil-water two-phase pseudopressure function, a horizontal well oil-water two-phase productivity prediction model considering the actual well trajectory was established. The study results show that the oil production distribution along the horizontal well is generally "U"-shaped, with fluctuations in flow rate due to the actual well trajectory; as the length of the horizontal well increases, the oil production slowly increases; the production of each section of the horizontal well is positively correlated with permeability, and passing through high-permeability formations helps enhance productivity. In addition, the shape of the relative permeability curve has a significant impact on oil and water production. The concave water phase at low water saturation has the best oil production performance, while the reservoir water saturation increases with the oil production of the well gradually decreases. This study provides a theoretical basis for optimizing horizontal well design and improving well productivity.

Key words: horizontal well productivity, oil-water two-phase flow, equivalent wellbore radius principle, pressure drop superposition theory, actual well trajectory
