目前随着S95块的深入开发,油藏已进入开发后期,表现出综合含水高、采油速度低的特征,产量形势比较严峻。本文针对S95块高凝油油藏的特殊性,储层物性差,受冷伤害影响严重,注水开发效果一般等问题,着重分析S95块一次压裂效果,并根据一次压裂效果建立重复压裂选井选层标准,对重复压裂候选井按从优到劣进行排序,定量判断合适的候选井,经矿场实例验证该方法具有较高的可靠性,对重复压裂选井具有重要的指导意义。
At present, with the in-depth development of S95 block, the reservoir has entered the late stage of development, showing the characteristics of high integrated water cut and low oil recovery rate, and the production situation is rather harsh. In view of the particularity of S95 block high pour-point oil reservoir, poor reservoir physical properties, serious impact of cold damage and general waterflooding development, this paper focuses on the primary fracturing effect of S95 block and establishes a series of fractures according to the primary fracturing effect The well selection criteria are selected, and the candidate wells are sorted according to their preference. The candidate wells are quantitatively determined. The field test shows that the method has high reliability and is an important guide to the selection of well for repeated fracturing significance.
