摘　　要：针对A凹陷储层由于岩性变化大、凝灰质胶结严重、孔隙结构复杂等因素造成的油水层难以区分的问题,应用模糊综合评判方法,综合考虑各种相关因素,以A凹陷流体识别影响因素分析为基础,以试油资料和测井资料为依据,研发了该区块储层流体识别技术.通过实际应用验证,准确率达到91.7%.Aiming at the problem of difficult identifying oil and water in the reservoir of sag A, which is caused by great lithology variation, complex porosity structure, tuffaceous cemented and fuzzy water boundry, a fluid identification technolgy was developed based on the influence of fluid identification by concerning different factors, using well test data and applying fuzzy synthetic e- valuation. The practical application proved that the accuracy of the technology was 91.7% .
