【摘要】：红岗北扶余油藏属于低孔低渗油藏。2012年通过红90-1区的水平井开发试验,初步明确了红岗北扶余油藏可以依托水平井技术实现陆续动用。但是存在着水平井砂层钻遇率低、井间储层变化大、水平井轨迹难以控制等情况。需要对红岗北扶余油藏开展水平井开发区域的精细三维地震构造解释和储层预测,用以指导2013年所部署的水平井,提高油层钻遇率,降低产能建设投资,提高动用效益。本项目借助地层精细对比、地震精细解释、储层反演等技术开展砂体预测,结合沉积相模式,对红岗北扶余油藏三角洲平原的分流河道进行精细的研究,精细刻画砂体的分布情况。分析影响水平井钻遇率的主要因素,开展水平井轨迹的地质导向工作,为水平井井位部署和调整提供地质依据。水平井技术近几年得到了蓬勃发展,但是水平井的轨迹地质导向一直是个难点,相关文献也比较少。本项目在研究过程中根据以往的经验结合本地区的特征探索了一套适合本地区的水平井实钻跟踪的方法。从地震资料、井资料、储层反演结果这三方面的信息相互分析和相互验证,有效的指导了水平井轨迹的调整,进而提高水平井的砂岩钻遇率。
[Abstract]:The Fuyu reservoir in North Honggang belongs to low porosity and low permeability reservoir. Through the horizontal well development test in Hong90-1 area in 2012, it is preliminarily clear that the reservoir can be used gradually by horizontal well technology, but there is a low drilling rate of sand formation in horizontal well. In order to guide the horizontal wells deployed in 2013, it is necessary to carry out the fine 3D seismic structural interpretation and reservoir prediction in the horizontal well development area of Fuyu reservoir in the north of Honggang in order to guide the horizontal wells deployed in 2013. In this project, sand body prediction is carried out by means of fine stratigraphic correlation, fine seismic interpretation and reservoir inversion, combined with sedimentary facies model. In this paper, the distributary channel in delta plain of Fuyu reservoir in northern Honggang is studied, the distribution of sand body is described, the main factors affecting the drilling rate of horizontal well are analyzed, and the geological guidance work of horizontal well trajectory is carried out. To provide geological basis for horizontal well location arrangement and adjustment. Horizontal well technology has developed vigorously in recent years, but the trajectory geological guidance of horizontal well has always been a difficult point. In the course of the research, according to the past experience and the characteristics of this area, we have explored a set of real drilling and tracking methods suitable for the horizontal wells in this area. The three aspects of reservoir inversion results are mutually analyzed and verified, which can effectively guide the adjustment of horizontal well trajectory, and then improve the sandstone drilling rate of horizontal well.
