摘要
随着钻探技术的进步与发展,水平井在油田上成为油气增产,提高勘探开发效益的一项重要技术。中山川水资源区有5.76km2尚未勘探,利用水平井勘探开发延长组长6油层,可以大幅度提高难动用储量的勘探开发效果,提高产量和采收率。经过对中山川水资源区周边油井精细的小层划分与对比,研究水资源区长6油层沉积相、砂体展布特征以及油层的分布规律,在结合精细的地质模拟,为设计水平井靶前距、水平段长度、水平段方位和靶点轨迹提供了重要依据。
Along with Progress and development of the drilling,horizontal drilling which can increases oil and gas and improve efficiency of drilling and exploitation in oilfield is one of the important technology. There is 5.76 km2 unexplored in the water resource region of Zhongshanchuan,it can significantly improve exploration and development effects of difficult to use reserves,production and oil recovery by using of horizontal wells to extend exploration and development of Chang 6.According to conduct a small layer of fine division and correla- tion of well in Water Resource Region of Zhongshanchuan, sedimentary microfacies, distri- bution characteristics of sand body and distribution of oil of Chang 61 been studied, deposit- ed with geological simulation,for the design of target from before,horizontal section length,ori- entation of the horizontal section,target trajectory of horizontal wells provide an important ba- sis.
