【摘要】：YM白云巖油藏已進(jìn)入高含水開(kāi)采期,如何尋找剩余油并進(jìn)行挖潛是目前面臨的重要問(wèn)題。該類(lèi)型儲(chǔ)層中普遍存在低滲透條帶,建立機(jī)理模型,通過(guò)對(duì)低滲透條帶的滲透率、厚度、產(chǎn)狀及與儲(chǔ)層滲透率的組合關(guān)系進(jìn)行敏感性分析,研究結(jié)果表明,滲流阻擋作用的強(qiáng)弱主要與其滲透率大小有關(guān),當(dāng)滲透率小于0.01 mD時(shí),能夠起到較好的滲流阻擋作用;同等條件下,厚度越大,滲流阻擋作用越強(qiáng);根據(jù)分布形態(tài)與樣式不同,對(duì)剩余油的控制程度Ⅰ類(lèi)Ⅱ類(lèi)Ⅲ類(lèi)Ⅳ類(lèi);若有兩條交錯(cuò)的低滲透條帶,則對(duì)剩余油的控制程度Ⅴ類(lèi)Ⅵ類(lèi)。低滲透條帶在一定生產(chǎn)時(shí)間內(nèi)可以形成滲流屏障,成為控制剩余油分布的重要因素。
[Abstract]:YM dolomite reservoir has entered the high water cut stage, how to find the remaining oil potential and is currently facing a major problem. Low permeability zone of this type of reservoir, establish the mechanism model, based on the low permeability, thickness, occurrence, and reservoir permeability rate of the combined relationship the sensitivity analysis results show that the strength of the main seepage blocking effect and its permeability is related to the size, when the permeability is less than 0.01 mD, can play a better role of seepage barrier; under the same conditions, the greater the thickness, the stronger the effect of seepage barrier; according to the distribution of different form and style, the remaining oil control degree of class II class III IV; if there are two staggered low permeability zone, the residual oil control degree V vi. Low permeability zone in a certain production time can be formed within the flow barrier, as control of residual oil distribution system Important factors.
