摘要: 特低丰度薄油层具有储量丰度低、储层薄、渗透性差的特点,而水平井开发技术可以有效地解决薄油层开发中存在的问题。利用水平井注采井网开发低渗、薄层油藏,可增大注入量、降低注入压力、有效保持油藏地层压力,提高油藏采出程度,从而改善油藏开发效果。针对特低丰度薄油层的特点,建立地质模型,设计水平井注采基础井网,对基础井网进行开发效果预测,筛选出典型井网,对典型井网进行参数组合及经济评价,最后得出水平井开发薄油层的优势井网,为提高特低丰度薄油层水平井注采井网的开发水平提供依据。

Abstract: Ultra-low abundance and thin oil layers have the characteristics of low reserves abundance, thin reserves and poor permeability. Horizontal well technology can effectively solve the problem in ultra-low abundance and thin layers. Horizontal injection pattern can increase the injection rate, reduce the injection pressure, maintain the reservoir pressure and improve the production efficiency. In view of these characteristics, we establish the geological model, design the basic horizontal injection-production well pattern, and select the typical pattern to perform analysis and evaluation. The dominant pattern is obtained, which can provide the basis for enhancing reservoir production levels using horizontal well pattern in ultra-low abundance and thin layers.
