【摘要】：针对小岩心物理模拟实验不能模拟水平井井网方式对水驱效果影响的问题,开展了模拟储层条件下的能在高温、高压下通过改变管线不同切口变换井网方式的水平井大岩心物理模拟室内试验,研究了水平井-水平井交错井网、水平井-水平井平行井网、直井-水平井交错井网、直井-水平井平行井网、直井-直井井网这5种不同的水平井井网类型的水驱油规律及剩余油分布特征,并建立了数值模拟预测模型进行对比、验证。结果表明:在渗透率级别相同的情况下,对比5种井网类型,水平井-水平井交错井网驱油效率最高,剩余油分散。水平井大岩心物模实验所得出的对水平井井网和直井井网的对比分析结论对指导油田现场井网的部署具有重要意义。
[Abstract]:Aiming at the problem that the physical simulation experiment of small core can not simulate the effect of horizontal well pattern on water drive effect, the energy of simulating reservoir is developed at high temperature. Under high pressure, the horizontal well pattern, horizontal well pattern, horizontal well pattern, horizontal well pattern, horizontal well pattern, horizontal well pattern, horizontal well pattern, horizontal well pattern, horizontal well pattern, horizontal well pattern, horizontal well pattern, horizontal well pattern, horizontal well pattern, horizontal well pattern, horizontal well pattern, horizontal well pattern, horizontal well pattern, horizontal well pattern, horizontal well pattern, horizontal well pattern, horizontal well pattern and horizontal well pattern are studied. The water drive rule and remaining oil distribution characteristics of five different horizontal well pattern types, parallel well pattern and horizontal well pattern, are established and compared with numerical simulation prediction model. The results show that in the case of the same permeability level, compared with five types of well pattern, the horizontal well and horizontal well staggered well pattern drive efficiency is the highest, The comparison and analysis of horizontal well pattern and straight well pattern is of great significance for guiding the deployment of oilfield field well pattern.
