【摘要】：為了研究縫洞型碳酸鹽巖油藏注氮?dú)馀菽尚行约坝绊懸蛩?研制了縫洞型碳酸鹽巖油藏細(xì)觀物理模型和宏觀剖面可視化物理模型,可由細(xì)觀到宏觀對縫洞型油藏注泡沫可行性及其影響因素進(jìn)行室內(nèi)物理模擬。細(xì)觀物理模型實(shí)驗(yàn)結(jié)果表明:水驅(qū)后,剩余油主要以封閉孔洞內(nèi)剩余油、閣樓油、繞流油和油膜的形式存在;氮?dú)馀菽芡ㄟ^重力分異及阻力效應(yīng)啟動(dòng)閣樓油與繞流油并剝離油膜。在宏觀剖面可視化物理模型上進(jìn)行了注泡沫影響因素研究。實(shí)驗(yàn)結(jié)果表明:在含油飽和度較低時(shí),以低部位井注、高部位井采(低注高采)的方式注泡沫效果更好,注泡沫時(shí)機(jī)不宜過早,宜在充分水驅(qū)的基礎(chǔ)上轉(zhuǎn)注泡沫;底水能量過強(qiáng)則不利于注泡沫,同時(shí)存在一個(gè)最優(yōu)的泡沫注入量。對于碳酸鹽巖縫洞型油藏開采中后期,注泡沫開采能夠有效維持高效開發(fā),提高原油采收率。
[Abstract]:In order to study the feasibility and influencing factors of nitrogen foam injection in fractured and cavernous carbonate reservoir, a meso-physical model and a macroscopic section visualization physical model were developed. The feasibility of injection foam and its influencing factors can be simulated in laboratory from meso to macroscopically. The results of meso-physical model experiments show that after water flooding, the remaining oil mainly exists in the form of residual oil, loft oil, flow oil and oil film in the closed hole. Nitrogen foam can activate attic oil and circumfluence oil and strip oil film through gravity differentiation and drag effect. The influencing factors of foam injection are studied on the physical model of macroscopic profile visualization. The experimental results show that when the oil saturation is low, the foam injection is better in the low position well injection, the high part well production (low injection and high production) method, and the foam injection timing should not be premature, and the foam injection should be changed on the basis of sufficient water flooding. Too strong bottom water energy is not conducive to foam injection, and there is an optimal foam injection rate. In the middle and late stage of carbonate fracture-cavity reservoir production, foam injection can effectively maintain high efficiency development and improve oil recovery.
