新店油田储层精细描述及注水开发研究
|
摘要
本文在分别对新店油田精细地质研究的基础上，通过油藏工程方法进行理论研究，建立了该地区的数学模型，然后经过历史拟合，对该地区的含水率和产量进行了预测。并针对两个地区的实际情况提出了调整注采结构的建议方案。
通过研究新店油田的开发特点、数值模拟和综合调整方案的预测结果，从油藏工程方法分析了新店油田的开发特点。对油田的原始地质储量、区块原始地层压力、区块实际的采出程度和区块的综合含水拟合的较好。这为后面的数模分析打下了良好基础。研究表明新店油田的萨尔图油层为三角洲内前缘亚相沉积，这与西部外围其它油田萨尔图油层的外前缘亚相有明显不同。新店油田纵向上油气水间互分布，气层主要分布在SⅠ-GⅢ等油层组的7个沉积单元内。本文对储层的动用情况进行了研究，重新按单砂体计算了储量。通过数值模拟得出，新店油田具有加密潜力和外扩潜力。可布加密井6口，外扩井7口。油田外扩井完钻后，应采取转注杜31-13、杜35-13、杜39-14、杜49-14、杜46-14五口井的点状分层注水方式，采油速度控制在2％，注采比为1.2，注水强度为2.6m3 m·d时，注水开发将达到较为理想的结果。
This article is based on the accurate formation description and establish reservoir mathematical model of this field by the theorical research of reservoir engineering. Then predict water cut and production by history fitting and direct out how to unjust the injection-production system to the field.
In this article, by analyzing the development characters of Xindian field, numerical simulation and the predict results of generally unjust means, it fit with the original georgic reserves, original geological pressure of oil area, the actual recovery and water cut very well. This can benefit for numerical simulation. The research can predict that Saertu reservoir of Xindian field is the front surfaces sedimentation of delta and it is different from outer front surfaces of other Saertu reservoir in the west. It is distributed by oil, gas and water vertically in Xindian field and gas reservoir distributes in the seven sedimentation units of the reservoir of S I - GIY. This article also includes the research of the producing reserves of reservoir and calculates the reserve according to monomer-sand. Xindian field has the potential of in filled and out pushed by numerical simulation. It can distribute 6 in-filled wells and 7 out-pushed wells. After the out-pushed wells are finished, the field should take the method of separate zone water injection. There are 5convented injection wells and they are Du3 1-13. Du35-13. Du39-14. Du49-14. 46-14. the oil recovery rate is controlled on 2%. injection-production ratio is 1.2. water intake per unit thickness is 2.6m3/m.d. then the effect of water flood will be very good.
