摘要:

针对塔河油田碳酸盐岩油藏底水能量不足油井产量递减快及采收率低的状况,提出对这部分油井开展单井注水吞吐开采试验,利用油水重力分异原理实现油水置换并补充地层能量,加快原油流入井筒、增加井筒举升能量,进而提高此类井的产能和采收率。通过对先期试验井T707的数值模拟,表明碳酸盐岩油藏底水能量不足油井单井注水吞吐开采是可行和高效的。通过对32口井推广试验,单井初期日增油13~285 t、周期增油55~3 105 t,取得了较好的试验效果和较高的经济效益,摸索出了一种碳酸盐岩油藏有效的新的开采方式。

Abstract:

Given consideration to the situation of fast descending of production and the recovery factor in Tahe oilfield, the water injection and production were experimentalized on the spot. The experiment separated oil and water, supplied the reservoir energy, made speed the oil flow into well bore, added the lift energy, and enhanced the production and the recovery factor of the reservoir by using the principle of gravitative differentiation. The result of onthespot experiment in well T707 indicates that water injection and production are feasible and available. By applying the measure to 32 oil wells, the increment of oil production was 13 to 285 t and the increment in period was 55 to 3,105 t. Therefore, the technology is a new effective production mode in carbonated reservoir.

Key words: carbonate reservoir, water injection and production, recovery factor, production mode, numerical simulation
