摘要
以东濮凹陷胡状集油田胡十二块油藏为解剖对象，探索了一套高含水期剩余油分布的多学科研究方法。以储层地质学、地质统计学和油藏工程等为理论基础，采取由点到面、静动结合、多学科协同的研究方法，应用虚拟井预测方法研究了单井剩余油分布特征，分微相建立了不同的水淹模式；根据正演井间分形克里格方法建立的非均质概念模型与示踪剂方法的有机结合很好地指示了井间剩余油分布情况；应用动态综合分析法、物质平衡法、水驱特征曲线法以及油藏数值模拟技术等从不同的侧面研究了本区的剩余油分布规律。
Aiming at the No.12 Fault-block reservoir of Huzhuangji Oilfield in Dongpu Depression, a series of interdisciplinary approaches are researched to study the remaining oil distribution during the high-watercut stage. Based on reservoir geology, geostatistics and reservoir engineering etc. the dynamic and static data and the all research methods are synthesized to study the distribution rules of the remaining oil in layers, interlayers and all over the 2-D areas. For example, pseudo-well forecasting method is applied to study the remaining oil distribution of a single well, establishing different water-floodriing models corresponding to sedimentary microfacies. The heterogeneous geological conceptual models built up by using Forward Interwell Fractal Kriging and the traccr technique are combined together to indicate the interwell remaining oil distribution conditions. The dynamic comprehensive analysis method, the material balance method, the water-driving characteristic curves and thc reservoir numerical modeling techniques are adopted to study the remaining oil distribution rules from diffcrent aspects. These approaches are helpful for implementing the 'Retaining Oil & Chntrolling Water' scheme in China's complex terrestrial fault-block reservoirs.
