高台子油田扶杨油层油水分布复杂,该区属于尚未进行大规模开发的地区。为了正确识别油水层并为制定油田开发方案提供依据,建立该地区油水关系解释图版和识别标准显得尤为重要。通过储层“四性”(指岩性、物性、含油性、电性)关系研究,应用交会图版法、油水层综合评价标准来综合识别油水层。同时,应用逐步判别分析的方法,建立高台子扶杨油层的油层、差油层、水层和干层的判别函数模型。通过回判率检验表明,建立的判别模型效果显著。通过以上这两种方法的配合能对油水层的识别更加精确。
The oil and water distribution in Fuyang reservoir of Gaotaizi Oilfield is complex, which belongs to the area that has not yet been developed in a large scale. In order to correctly identify the oil-water layer and provide a basis for the development of oilfield development plans, it is particularly important to establish a map and identification standards for oil-water relations in the region. Through the study of reservoir “four ” (referring to lithology, physical property, oiliness, electrical property), the oil and water layer is synthetically identified by the method of rendezvous diagram and the comprehensive assessment standard of oil and water. At the same time, discriminant function model of oil layer, poor oil layer, water layer and dry layer of Gaotaizi Fuyang oil reservoir was established by stepwise discriminant analysis. The test of return rate shows that the discriminant model is effective. Through the combination of these two methods, the recognition of the oil-water layer can be more accurate.
