摘要： 准噶尔盆地陆梁油田陆9 井区下白垩统呼图壁河组油藏为典型的薄油层、边底水活跃的砂岩油藏,开发过程中受边(底)水推(锥)进及注入水突进影响,部分油井含水高、采出程度低且增产难度大。为提高油藏开发效果,利用多种手段对油层水淹状况和水驱规律进行了系统研究,确定了剩余油富集区。通过运用油藏工程和数值模拟,对侧钻水平井主要技术参数进行了优化。2008—2009 年共实施侧钻水平井14 口,平均单井增油8.1 t/d,含水下降47.2 个百分点,恢复产能2.69×104 t,效果十分显著。

Abstract: The Hutubihe reservoir of Lower Cretaceous in Wellblock Lu-9 in Luliang oil field in Junggar basin is a typical sandstone reservoir with thin oil layers and active edge and bottom water. Affected by the edge and bottom water coning and injected water breakthrough, some wells have entered into high water cut stage with low recovery factor and difficult incremental production. For this reason, several measures have been applied to in-depth study of watered-out oil layers' status and water drive regularity and determination of remained oil-enriched area. This paper optimizes the main technical parameters of sidetracking horizontal well by means of reservoir engineering and numerical simulation. In 2008-2009, 14 sidetracking horizontal wells were drilled, with incremental production per well of 8.1 t/d in average, water cut drawdown by percentage of 47.2 and productivity increase of 2.69×104 t.

Key words: Junggar basin, Luliang oil field, edge-bottom water reservoir, remained oil, sidetracking horizontal well
