摘要:

渤海油田D5H井所在区块以底水构造油藏为主,油井投产后出水严重,应用中心管和变密度筛管等方式控水效果

不佳。基于D5H井的控水方案设计流程,尝试使用ICD分仓控水方法进行作业,控水效果较好;进而提出一套适用于该油田的ICD控水效果定量评价方法:(1)与相邻同

层位生产井含水率对比法;(2)与原始配产含水率对比法;(3)与校正数值模拟结果(模拟井不控水的含水率)对比法。采用该方法对D5H井和变密度筛管控水的D2H

井控水效果进行评价,结果显示,D5H井的平均增油速率为60433 m3/a,而D2H井仅为21287 m3/a,表明ICD分仓控水方法的控水效果明显优于变密度筛管

控水效果。该研究结果对渤海油田推广使用ICD分仓技术以及定量评价单井的控水效果具有很好的指导和借鉴作用。

Abstract:

The block where the well D5H located in Bohai Oilfield is dominated by the bottom

water structure reservoir, after production, the oil well produced lots of water. Despite the use of a central tube and a variable density screen

to control water, the effect is not good. Based on the design process of the water control of the well D5H, the ICD water control method was

tried, it was found that the water control effect was very good. Therefore, based on this, a set of quantitative evaluation methods for ICD water

control effect suitable for the oilfield is proposed, which includes: (1) Comparison of water content in the same layer of adjacent production

wells; (2) Comparison of water content for the original allocation; (3) Comparison method of corrected numerical simulation result (water content

of simulated wells without water control). Comparing the water control effect of well D5H and D2H(variable density screen method), the results

show that the average increase rate of oil production in well D5H is 60433 m3/a, while well D2H is only 21287 m3/a. This indicates

that the water control effect of the ICD water control method is significantly better than that of the variable density screen. The research

results have a good guidance and reference for the promotion of ICD technology in Bohai Oilfield and the quantitative evaluation of the water

control effect of single well.
