大芦湖油田樊18-3块主力含油层系为沙三中、下4-10砂组。含油面积沙三中4.0km2,沙三下3.5km2,地质储量沙三中415×104t,沙三下239×104t。根据地质认识,针对本块试油试采情况,运用数值模拟技术进行了注水时机、注采比优化,并对方案的指标进行了预测。
Dafuhu Oilfield Fan 18-3 main oil-bearing sand system in the sand, the next 4-10 sand group. 4.0km2 in Sha3, 3.5km2 in Sha 3, 415 × 104t in Sha 3 and 239 × 104t in Sha 3. According to geological cognition, aiming at the situation of trial oil-extraction in this block, the timing of water injection, the optimization of injection-production ratio were simulated by numerical simulation technology, and the project’s indexes were predicted.
