【摘要】：聚合物驅為大慶油田的高產和穩(wěn)產發(fā)揮了巨大作用,聚合物驅進一步提高油藏采收率后,仍有一部分原油殘留在地層中未被采出,因此開展聚合物驅后水驅精細挖潛措施研究對聚驅剩余油挖潛、進一步提高采收率以及指導后續(xù)注聚區(qū)塊聚合物驅開采有著至關重要的意義。本文目標區(qū)塊為大慶油田杏4-6面積區(qū)塊,目標區(qū)塊水驅后進行聚合物驅。利用Petrel地質建模軟件建立目標區(qū)塊水驅階段相控三維地質模型,結合Eclipse數值模擬軟件對全區(qū)水驅階段進行歷史擬合,并研究其水驅后剩余油分布類型及成因;針對目標區(qū)塊聚驅目的層建立其相控三維地質模型,利用分層注聚歷史擬合技術對聚驅階段進行歷史擬合,并研究聚驅后剩余油分布情況;分析聚驅后剩余油分布類型及成因,進行后續(xù)水驅開發(fā)效果預測。針對聚驅后水驅精細挖潛措施調整,主要從停高滲、壓裂、堵水、注采系統(tǒng)調整以及周期注水這五個方面進行研究。首先分析目標區(qū)塊后續(xù)水驅潛力的分布,針對后續(xù)水驅潛力較大的地區(qū),分別進行上述調整措施研究;對典型停高滲注入井驅油效果進行分析并提出目的區(qū)塊目的層停高滲的措施方案;根據壓裂、堵水及注采系統(tǒng)調整原則選取油水井進行相應的措施調整,并對措施效果進行分析;最后綜合上述效果分析結果給出杏4-6面積井網聚驅后水驅挖潛措施調整最優(yōu)措施方案。
[Abstract]:Polymer flooding has played a great role in high production and stable production in Daqing oilfield. After polymer flooding further improves oil recovery, a part of the residual oil remains in the formation. Therefore, the study on the fine potential of water flooding after polymer flooding has been carried out to explore the potential of residual oil for polymer flooding, to further improve the recovery rate and to guide the follow-up polymer injection area. The block polymer flooding is of vital significance. The target area is the 4-6 area block of apricot area in Daqing oilfield. The target block is driven by polymer flooding after water flooding. The phase controlled three-dimensional geological model of the target block water drive phase is established by using the Petrel geological modeling software, and the water flooding stage of the whole area is fitted with the Eclipse numerical simulation software. The distribution types and causes of residual oil after water flooding are studied. A three dimensional geological model is established for the target zone of the target block polymer flooding. The historical fitting of the polymer flooding stage is made by the stratified polymer injection history fitting technique, and the distribution of residual oil after the polymer flooding is studied. The distribution types and causes of residual oil after the polymer flooding are analyzed, and the subsequent water flooding development is carried out. Effect prediction. According to the adjustment of water flooding fine digging measures after polymer flooding, mainly from five aspects of stopping high seepage, fracturing, water plugging, injection production system adjustment and periodic water injection. First, the distribution of the following water flooding potential in the target area is analyzed, and the above adjustment measures are carried out according to the larger potential area of the follow-up water flooding. The effect of oil flooding in high permeability injection well is analyzed and the measures to stop high permeability of target area are put forward. According to the principle of fracturing, water plugging and injection production system adjustment, the adjustment of oil and water wells is selected and the effect is analyzed. Finally, the results are integrated with the results of the 4-6 area of apricot area. Adjust the optimal measures.
