| 摘 要： | 探讨苏里格气田水平井地质三维导向技术,为水平井规模化开发提供新的思路和技术。以区域地质背景、区块砂体展布规律为基础,由常规二维地层对比求取地层视倾角发展为地层三维空间对比求取真倾角,精细对比地层及储层展布情况,并结合辫状河沉积微相及其发育特征和随钻参数分析评价开展水平井地质导向分析。研究区盒8段辫状河道主要发育河道充填、心滩微相、废弃河道、越岸沉积4种微相;以沉积微相分析技术为基础的地质三维导向能够有效保证水平段钻遇率。在储层三维空间对比闭合基础上,形成了以沉积微相赋存规律、砂体地质规模及特征分析为核心的水平井地质三维导向技术,完善了水平井地质导向方法。 |

| Abstract: | The discussion on three‐dimensional geosteering technology for the horizontal wells in Sulige gasfield provides some new ideas and technology for the development of large‐scale horizontal wells .The analysis of horizontal well three‐dimensional geosteering technology is carried out through obtaining true dip via three dimensional comparison with apparent dip in two ‐dimensional ,precise strata correlation ,and reservoir distribution , recognizing the braided river facies of micro‐facies and characteristics ,and analyzing the regional geological background and distribution of sand bodies .The He8 Group braided river sub‐facies mainly include channel‐filling ,channel bar , abandoned channel , overbank deposit .Based on the analysis of sedimentary microfacies ,the three‐dimensional geosteering technology can effectively guarantee the horizontal drill encounter rate . The three‐dimensional geosteering technology is developed based on three dimensional comparison , sedimentary microfacies scale ,and their characteristics . It can expand and extend the development of the horizontal well geosteering methods and techniques ,and effectively promote its application . |
| Keywords: | horizontal well reservoir correlation three-dimensional geosteering geological model Sulige gasfield |
