摘要/Abstract

摘要： 针对滴12井区八道湾组油藏非均质性严重、大孔道发育、含水上升速度较快、小剂量调剖效果较差等特点,提出深部调驱技术早期介入、区块整体进行深部调驱的治理思路。研发了适合该区块的以聚丙烯酰胺为主的深部调驱凝胶体系,该体系具有很好的成胶强度和封堵效果,现场试验为了提高对较大水窜通道的封堵能力,在调驱凝胶体系中加入了固相颗粒。2010年在滴12井区进行了4个井组的调驱措施,注水井平均注入压力上升1.85 MPa,措施井组日产油由2.0 t 上升到最高3.1 t,综合含水由57.8%下降到56.6%,4个井组目前累计增油1 063 t,效果较好。

Abstract: The Badaowan reservoir in D-12 well area in Cainan oilfield is characterized by serious heterogeneity, developed big pores, rapid climbing water cut and poor response of small dose profile control, etc. This paper puts forward a managing idea of early applicating deep profile controlling technology and conducting overall deep profile control in this area. A jel system for deep profiel control dominated by polyacrylamide that is more suitable for this area is developed. In order to enhance plugging capacity to bigger water breakthrough channels, the solid grains are added into the system. In 2010, the profile controls were conducted in four well groups in D-12 well area, then averaging injection pressure in injection wells rises by 1.85 MPa, daily oil increases from 2.0 t to 3.1 t, composit water cut decreases from 57.8% to 56.6%, and present cumulative incremental oil amounts to 1 063 t in the four well groups.

Key words: Cainan oilfield, D-12 well area, deep profile control, polymer, gel, solid grain
