摘要:
中海油刚果(布)Haute Mer A 区块为深水出砂稠油油藏,根据常规的挡砂精度设计准则采用砾石充填防砂后出油困难。为了确定合理的挡砂精度,提出了海上稠油防砂不同设计原则下的最大含砂浓度标准,并通过砾石充填出砂模拟实验, 采用“三曲线分析方法”,获得了不同于常规的防砂设计准则。该分析方法同时考虑了砾石充填层的相对渗透率、剩余渗透率及含砂浓度标准。实验结果表明,充填层砾石粒度中值为地层砂粒度中值8~9 倍时充填层渗透性最好;采用该设计准则确定的防砂挡砂精度油井产能提高了3 倍多,解决了该区块防砂后出油困难的问题,为该类稠油出砂油藏挡砂精度设计提供了新的思路。
Abstract:
Haute Mer A block is a sanding deep-water heavy oil reservoir in Congo sea, it had a low productivity after being applied to gravel pack technique which followed the conventional accuracy of sand control principle. In order to obtain a reasonable accuracy of sand control, the maximum sand concentration was proposed based on different design principles of offshore heavy oil field, and an unconventional design rule was developed according to a gravel pack experiment and “analytical method by three curves”. The relative permeability, residual permeability and sand concentration could be considered by this method. Results show that the permeability reached the peak when the ratio of pack median grain size to formation median grain size varied within the range of 8 to 9, and accuracy of sand control designed by this new standard come to a higher productivity index 4 times than those designed by Saucier’s method. The problem of low oil production after sand control in Haute Mer A block had been resolved, and this may provide a new ideas for the design of sand control accuracy in heavy oil field.
