摘要：为提高大老爷府油田注水开发效果，针对目前区块开发中存在的主要问题，结合区块储层特征，开辟了老16-2并组先导试验并组，对该井组进行前期地质静态、动态分析及氮气泡沫驱适应性研究，结合储层特征，优化注入参数及工艺。通过水并注入氮气的模式，封堵高渗透出水层和补充地层能量，从而改善注采面，保持地层压力，扩大波及体积，提高动用程度，最终提高采收率。先导试验取得了较好开发效果，项技术的成功实施，为大老爷府油田提高注水开发效果提供了技术支持。

Abstract: In order to improve the effect of water flooding Dalaoyefu oil field, aiming at the main problems in the development of the block, combined with the reservoir characteristics, has opened up the old 162 well group pilot test wells group, early static geology of the well group, dynamic analysis and foam flooding adaptability research, combining with the characteristics of the reservoir, optimization the injection parameters and process. By injecting nitrogen into the water well, we can plug high permeable water production layer and replenish formation energy, so as to improve injection production profile, maintain formation pressure, expand sweep volume, improve production degree, and ultimately enhance oil recovery. The pilot test has achieved good results, and the successful implementation of this technology provides technical support for the improvement of water injection development effect in the big old lord oil field.

大老爷府注水开发现状及影响因素
注水见效后含水率大幅上升
1.1
该区块产油量由2014年年初的150t，下降到2015年年末的120t，递减速度快，含水由94%

上升到96.8%，含水上升速度快。 1.2注水开发低效原因
1.2.1区块整体注水开发低效因素
这个区受东西向裂缝及沉积展布影响，注人水沿裂缝及高渗条带突进，单层突进现象较严重，平面及层间矛盾特别突出。
1.2.2平面上东西向矛盾突出，注采敏感
通过老16-22与周围油井连通情况与注采动态反映来看，东西向井矛盾比较突出，老14
