【摘要】：本文以延長油田白狼城區(qū)塊為對象,對該區(qū)的高效注水開發(fā)進行研究。首先對區(qū)塊的基本概況進行了基本的研究,通過對該區(qū)塊生產資料的分析,對區(qū)塊注水開發(fā)效果進行評價,白狼城區(qū)塊自2004年12月開始注水開發(fā)到現(xiàn)在,月產油量從起初上升趨勢到現(xiàn)在基本保持平穩(wěn),產量趨于穩(wěn)定,含水率變化幅度不是很大,注水效果開發(fā)保持良好;再以油井為中心分析各向注水受效情況,發(fā)現(xiàn)多向受效井主要分布于油層中部,一向受效井和無注水受效井主要分布于油藏邊部,油井受效方向越多,受效程度越高,油井產量、含水受注水受效方向影響明顯;根據(jù)白狼城生產資料整理得到歷年注采比,結合地層壓力,研究了地層壓力與注采平衡對高效注水開發(fā)的影響,結果顯示地層壓力一直處于緩慢遞增趨勢,注采比基本保持平緩趨勢,隨著注水的開發(fā),地層壓力水平保持合理,形成注采平衡趨勢,保證了白狼城油區(qū)穩(wěn)產開發(fā)效果。最后,為了更好地對油田進行深度挖潛,強化油藏管理的針對性和有效性,結合對該區(qū)塊的注水開發(fā)效果分析,制定出合理完善的動態(tài)監(jiān)測方案,以及針對性較強的調整措施。
[Abstract]:This paper takes Bailangcheng block of Yanchang Oilfield as an object to study the development of high efficiency water injection in this area. Firstly, the basic general situation of the block is studied, and through the analysis of the production data of the block, To evaluate the effect of water injection development in block, from December 2004 to now, the monthly oil production has remained stable from the beginning to now, the output tends to be stable, and the range of water cut change is not very large. Taking the oil well as the center, it is found that the multi-directional effective wells are mainly distributed in the middle of the reservoir, and the traditional and non-water-infused wells are mainly distributed on the side of the reservoir, and the more the wells are, the more the effective directions of the wells are. The higher the efficiency degree, the more the oil well production and water cut are affected by the effective direction of water injection. According to the data of production in Bailang City, the injection-production ratio of the past years is obtained. Combined with formation pressure, the influence of formation pressure and injection-production balance on high efficiency water injection development is studied. The results show that the formation pressure has been increasing slowly and the injection-production ratio has maintained a gentle trend. With the development of water injection, the formation pressure level remains reasonable, forming the trend of injection-production balance, which ensures the stable production development effect in Bailangcheng oil area. In order to better tap the potential of the oil field and strengthen the pertinence and effectiveness of reservoir management, combining with the analysis of the water injection development effect in this block, a reasonable and perfect dynamic monitoring scheme is worked out, as well as the adjustment measures with strong pertinence.
