摘 要：碳酸鹽巖縫洞型油藏由于裂縫、溶洞的分布隨機(jī)性強(qiáng)，其流動(dòng)機(jī)理和開(kāi)發(fā)方式與常規(guī)的碳酸鹽巖裂縫性油藏存在很大差別，注水開(kāi)發(fā)目前處于試注階段，還沒(méi)有形成相應(yīng)的油藏注水開(kāi)發(fā)理論體系。因此，建立適合碳酸鹽巖縫洞型油藏的注采關(guān)系及注水方式，優(yōu)化碳酸鹽巖縫洞型油藏不同注水方式下的注采參數(shù)，是碳酸鹽巖縫洞型油藏注水開(kāi)發(fā)理論與方法的關(guān)鍵基本問(wèn)題。本研究以油藏工程學(xué)、流體動(dòng)力學(xué)理論為基礎(chǔ)，以室內(nèi)物理模擬實(shí)驗(yàn)、數(shù)值模擬、礦場(chǎng)注水試驗(yàn)和大量動(dòng)態(tài)資料統(tǒng)計(jì)分析為基本手段，充分考慮理論研究、室內(nèi)實(shí)驗(yàn)研究與現(xiàn)場(chǎng)試驗(yàn)研究相結(jié)合，針對(duì)課題研究目標(biāo)，選擇具有代表性的縫洞單元模型進(jìn)行重點(diǎn)研究，對(duì)油藏能量、注采關(guān)系、注水方式、注采參數(shù)、注水開(kāi)發(fā)動(dòng)態(tài)及開(kāi)發(fā)效果評(píng)價(jià)方法進(jìn)行深入研究，進(jìn)而形成系統(tǒng)的縫洞型油藏注水開(kāi)發(fā)技術(shù)政策及注水開(kāi)發(fā)效果評(píng)價(jià)方法。2013年通過(guò)進(jìn)一步開(kāi)展室內(nèi)物模和數(shù)值模擬研究，建立了縫洞型油藏室內(nèi)三維注才井組實(shí)驗(yàn)?zāi)Ｐ停晟屏丝p洞型油藏單元注水方式，優(yōu)化了縫洞型油藏單元注水的注采參數(shù)，進(jìn)一步完善了不同類型巖溶縫洞儲(chǔ)集提注水技術(shù)政策。該課題完成了年度研究計(jì)劃內(nèi)容和目標(biāo)。

Abstract：Because of cracks， caves strong distribution randomness in Carbonate fracture cave reservoir. Its current mechanism and development mode have big difference with the conventional fractured carbonate reservoirs. Water injection development is currently in trial stage， Not form the corresponding theoretical system waterflooding reservoir.Subject to reservoir engineering、fluid dynamics theory， In physical simulation experiments， numerical simulation， the mine water testing and statistical analysis of a large number of dynamic data as the basic means. Fully consider the theoretical research， experimental research experiments and field studies combining indoor， For research objectives， Select fractured unit model to focus on a representative study， On the reservoir of energy， the relationship between injection， water injection mode， injection parameters， water development and development effectiveness evaluation method of dynamic depth study. Build relationships and water injection methods suitable for fracture-cave carbonate reservoir， Thus forming system vuggy reservoir waterflood injection technology policy and development effectiveness evaluation. Further indoor physical model and numerical simulation in 2013 year， Established a three-dimensional vuggy indoor injection wells experimental model group， Improved vuggy reservoir unit injection mode， Optimize the injection parameters vuggy reservoir water injection unit， Further improve the different types of karst fractured reservoir provides water technology policy. The subject completed the annual research program content and objectives.

Key Words：Tahe Oilfield；fractured-vuggy reserviors；Water flooding development；Water injection；Injection-production parameters
