长堤油田桩11块为具有活跃边底水的稠油油藏,利用直井开发含水上升快,为了改善其开发效果,在井间以及油藏顶部剩余油富及区域部署水平井,为了使水平井取得好的开发效果,对水平井开发该类油藏的开发技术界限进行了深入系统研究,研究结果表明,有隔层的区域有效厚度3m以上部署水平井效果较好,无隔层区域有效厚度5m以上部署水平井效果较好,越靠近油层顶部生产效果越好,射孔方式为一次射孔。
Pile 11 of Changti Oilfield is a heavy oil reservoir with active edgewater. The development of water cut-off by vertical wells is rapid. In order to improve the development effect, horizontal wells are deployed between wells and at the top of the reservoirs, Hirai achieved good development results and conducted an in-depth systematic study on the development technical limits of horizontal wells for the development of such reservoirs. The results show that the effective depth of 3m above the effective area of the horizontal wells is better than that of horizontal wells, The deployment of horizontal wells with a thickness of more than 5m is better. The closer the production is to the top of the reservoir, the better the perforation is.
