辽河油田齐40块蒸汽驱汽窜特征与控窜对策
CHARACTERISTICS AND COUNTERMEASURES OF THE STEAM FLOODING CHANNELING IN QI NO.40 BLOCK OF LIAOHE OILFIELD
摘要
Abstract
The steam channeling become serious day after day in Qi No. 40 Block of Iiaohe Oilfield, the proportion of the channeling for the well groups has reached 23. 5% . The steam fronts are unevenly undeveloped; the heat losses are severe; the development effects and economic benefits become worse. In accordance with the distribution laws and characteristics of the steam-channeled well groups in Qi No. 40 Block, the mechanism of the channeling is analyzed, and furthermore by integrating reservoir engineering methods and numerical simulation techniques, the suitable countermeasures for the channeling of different well groups are explored, among them, the effects of the following methods are pretty better-both effectively control the happen of channeling and improve the developed performances of the oil layers; nitrogen-aided steam flooding and alternating water-steam injection acted from head of the steam flooding. From 2009 to 2011, 79 well-times of successful anti-channeling measures are carried out in the whole block, the oil increment is not only upto 1.01×104t, more than, but also achieve obvious and high e-conomic effects. Therefore demonstrate important guiding significance for the anti-channeling control of the steam flooding of the heavy oil reservoirs in both the block and the other similar ones.关键词
