4—D储层预测技术及其在油田开发中的应用——以周清庄油田E3s3—5^1砂岩岩性油藏为例

4-D RESERVOIR PREDICTION TECHNIQUE AND ITS APPLICATION TO OILFIELD DEVELOPMENT:A CASE STUDY OF THE E3s3-51 LITHOLOGIC SANDSTONE POOL IN ZHOUQINGZHUANG OILFIELD

在油田开发过程中,很难用构造图和精细储层预测结果一次搞清楚岩性油藏的构造和储层空间分布特征,也很难据此一次完成这种油藏的整体开发方案编制,为此提出了一种4-D储层预测技术的思路与流程.4-D储层预测技术是一种针对岩性油藏滚动开发的应用技术,实际上是时间序列的多次3-D精细储层预测技术.随着新完钻井的资料的不断补充和应用,3-D精细储层预测技术的应用次数和精度将不断增加,据此所编制的油藏整体开发方案也愈切合油藏实际.通过该技术在周清庄油田E3s3-51砂岩岩性油藏的开发应用,先后所部署的13口开发井均取得100%的钻探成功,从而也证实了该项技术的有效性.

During progressive development in an oilfield, it is difficult to understand completely trap and reservoir space distribution of a lithologic oil pool by using its structure map and refined reservoir prediction, and it is also difficult to make an integrated development plan for such oil pool only one time. Therefore, an idea and a flow chart are presented for 4D reservoir prediction technique, an applicable technique aiming for progressive development of lithologic oil pools, which is actually composed of multiple 3-D refined reservoir predictions in time series. With the added data from new drilled wells, the times and accuracy of 3-D refined reservoir prediction will gradually increase, by which the integrated development plan made for the oil pool will be more practicable. This technique has been applied to E 3s 351 lithologic oil pool in Zhouqingzhuang oilfield, and the 13 placed development wells have achieved a 100% success, indicating effectiveness of the technique.
