摘　　要：东辛油田营13断块为具有边底水的复杂断块岩性-构造普通稠油油藏,由于生产压差较大、含水较高,直井冷采产能低。通过技术论证,决定改善该区块的开发方式,在构造高部位优化部署四口水平井进行热采,并对配套技术进行了优化,形成了HDNS技术,即水平井技术、油溶性降粘剂、氮气泡沫、蒸汽吞吐的组合。应用新技术后营13断块取得了很好的开发效果。Ying 13 fault-block,as a lithology-structure heavy oil reservoir with edge-bottom water,has low production when producing by straight hole because of the large producing pressure and the high water cut with cold producing method.Through technology demonstration,the development mode has been transformed,four horizontal wells on the high position of the structure have been deployed for thermal recovery.By optimizing technology,HNDS technology has been formed,which consisted by horizontal well technology,dissolver technology,nitrogen foam technology and steam technology.Good development results-13.7 tons of single well have been achieved at the beginning of the thermal recovery.It will be of great significance to the development of the similar reservoirs.
