摘要/Abstract

摘要： 哈萨克斯坦扎纳若尔气顶油藏采用在油气界面附近屏障注水,封隔油气区,先开发油环(油环采用面积注水),后期开发气顶或在水障形成后油气同采的方式进行开发。以该油田Б南油藏为例,在深入分析屏障注水量变化与气顶膨胀增油作用关系的基础上,探讨了以屏障注水结合油环内面积注水方式开发的气顶油藏,适时降低屏障注水量,充分利用气顶膨胀能量,实现高效益开发的可行性。应用数值模拟方法进一步确定了气顶油藏合理的年注采比以及屏障注水井和油环内面积注水井注水量的比例关系。

Abstract: The gas cap reservoirs in Janajol filed in Kazakhstan are developed through isolating the oil and gas zones by injecting water as a barrier adjacent to the gas-oil interface. The oil ring is to be recovered first (by pattern water-flooding in the oil rig), then the gas cap in the later stage or the oil and gas be developed simultaneously after the water barrier has been formed. Taking South Б pool of the field as an example, in-depth analysis of the relationship between the water injection volume of the barrier and the incremental oil production by gas cap expansion is made, by which the feasibility of developing the gas cap reservoir is examined by integration of barrier-water injection with pattern water-flooding in the oil ring, timing reduction of the barrier water injection rate, making full use of the gas cap expansion energy to gain high economic benefits. In addition, reasonable annual injection-withdrawal ratio as well as proportion of the barrier-water injection rate and the pattern water-flooding volume in the oil ring is determined by using numerical simulation methods.

Key words: Kazakhstan, oil ring, water injection, numerical simulation
