深南构造带滚动勘探开发实践与认识

Practice and understanding of rolling exploration and development in Shennan structural belt

针对深南构造带破碎、储层空间变化大、油水关系复杂等的特点,应用三维地震资料目标精细处理、精细解释、测井评价、定向井钻探等技术,结合地质、测井、录井、分析化验等资料,进行了综合地质研究,实现了低勘探开发区评价和寻找较整装油藏的滚动勘探开发,发现了深南断层上升盘的泽70和下降盘的泽10两个油藏(千万吨级储量规模的油田),并摸索出了一套行之有效的滚动勘探开发方法。

In view of the characteristics of Shennan structural belt,such as fractured structure,big variance of reservoir space and complex oil-water relationship,with the application of3D seismic data fine processing,fine interpretation,logging evaluation,directional well drilling technology technologies,and by fully utilizing geology,well logging,mud logging and analytical data,the comprehensive geological study has been carried out,which realized the low-degree exploration and development evaluation and rolling exploration and development of uncompartmentalized reservoir.Two reservoirs,Ze70in upthrow side and Ze10 in downthrow side have been found,with the reserve scale of 10-million-ton.These effective rolling exploration and development methods provide meaningful guidance for complex structure belts.
