摘要
塔中西部碳酸盐岩高效井以缝洞型储集层为主,在地震资料上主要表现为"串珠状"或"片状"强反射。研究高效井反射特征与储集类型以及开发动态等资料的关系,对碳酸盐岩地区井位优选有重要指导意义。利用地震剖面、工程异常及产能测试、开发动态等资料及数值模拟与精细储集层标定等技术,分析高效井与第一个波谷的厚度、横向延续距离以及有效储集层在剖面发育位置等特征的对应关系,总结出一套高效井的地震反射特征图版。据此图版优选高效井点,同时建议打水平井兼探非"串珠状"储集层,对高效开发塔中西部碳酸盐岩油藏有一定的帮助。
The high efficient wells in carbonate fractured-vuggy reservoirs in western Tazhong area are reflected as beads-shaped or sheet-shaped strong reflection from the seismic profile.Study on the relationships among the reflection,reservoir type and production performance is of significance for optimizing well location in this area.This paper presents the corresponding relationships among them,including the high efficient well reflection characteristics of the vertical range and horizontal distance of the first wave trough,and the location of effective reser-voirs in the seismic profiles,and gives a set of characteristic chart of the wells,based on data from the seismic profiles,engineering anomaly,deliverability test,production performance by means of techniques for numerical simulation and fine calibration of reservoirs.Because the first wave trough is large vertically and the horizontal distance is long,the best location of the high efficient well can be chosen.To drill hori-ontal wells and explore the non-beads-shaped reservoirs at the same time could be a good method for efficient development of such reservoirs.
