【摘要】：很多成功的水平井注水先例證明,低滲透油藏開發(fā)效果的改善得益于水平井注水技術(shù)的發(fā)展與應用。為了保持油藏的壓力能量平衡,水平井注水方式的不同組合可以提高注水效率和采出程度,經(jīng)濟效益也隨之提高。但是由于粘滯力對水平井井筒的影響,注水量突破之后,水平井注水效果很差,使水平井注水一直難以很好的利用。隨著水平井注水的普遍應用,低滲透油藏出現(xiàn)了新的研究領(lǐng)域即水平井井網(wǎng)的分布與優(yōu)化。近些年,隨著油氣開發(fā)的日益加深,注水井注水面積是否能得到充分的利用,是否能得到更高的采收效果,從而加大投資回報率,改善油田現(xiàn)有的開發(fā)狀態(tài),成為一個熱門的研究課題。由此可見,老油氣田的再開發(fā)與利用效果離不開水平井注水技術(shù)的廣泛應用。本論文主要利用室內(nèi)實驗研究及數(shù)值模擬研究等手段來確定合理的注采參數(shù)、對注采井網(wǎng)進行優(yōu)化研究,以及有針對性的調(diào)整注水手段,將為水平井注水開發(fā)油藏的穩(wěn)產(chǎn)、增產(chǎn)提供幫助。以邊臺潛山和勝西潛山油藏為背景,研究該類油藏復雜結(jié)構(gòu)井合適井型及注水開發(fā)方式,為該類油藏進一步提高采收率提供可靠的理論和技術(shù)支持;同時基于潛山油藏復雜結(jié)構(gòu)井注水開發(fā)的研究認識,針對邊臺潛山和勝西潛山油藏進行注水開發(fā)研究,為邊臺潛山油藏注水調(diào)整及進一步提高采收率提供實用方案和建議。
[Abstract]:Many successful horizontal well water injection precedents prove that the improvement of low permeability reservoir development results from the development and application of horizontal well injection technology. Different combinations of water injection methods in horizontal wells can improve the water injection efficiency and the degree of production, and the economic benefits will also be improved. However, due to the influence of viscous force on the wellbore of horizontal wells, the water injection effect of horizontal wells is very poor after the water injection rate breaks through. With the general application of horizontal well injection, a new research field, the distribution and optimization of horizontal well pattern, has appeared in low permeability reservoir. In recent years, with the development of oil and gas, the distribution and optimization of horizontal well pattern are becoming more and more important. Whether the water injection area of water injection wells can be fully utilized, whether it can get a higher recovery effect, thereby increasing the rate of return on investment and improving the existing development status of oil fields has become a hot research topic. The redevelopment and utilization effect of old oil and gas field can not be separated from the wide application of horizontal well injection technology. This paper mainly uses laboratory experiment and numerical simulation to determine reasonable injection-production parameters and optimize injection-production pattern. As well as the pertinent adjustment of water injection means, it will help to stabilize production and increase production of horizontal well water injection development reservoir. Taking Bian Tai buried hill reservoir and Shengxi buried hill reservoir as background, this paper studies the suitable well type and water injection development mode of complex structure well in this kind of reservoir. It provides reliable theoretical and technical support for further improving oil recovery in this kind of reservoir, and based on the understanding of water injection development of complex structure wells in buried hill reservoir, the waterflooding development of buried hill reservoir and Shengxi buried hill reservoir is studied. It provides practical schemes and suggestions for water injection adjustment and further improvement of oil recovery in buried hill reservoir.
