摘    要:振动采油、酸化压裂技术都是油气田开发中增产的可行途径。振动采油技术主要是利用振动波处理油层,通过压裂造缝、原油降粘等方法使油井增产提高,从而提高油层最终采收率。酸压技术是一种常用于碳酸岩油气藏的油井增产措施,即在高于破裂压力下向地层泵入盐酸,使其产生裂缝或压开天然裂缝,同时酸液始终在张开的裂缝中流动并与裂缝壁面反应,最终形成具有一定长度和一定酸蚀导流能力的裂缝,以提高储层渗流能力。在一些稠油、高凝油的碳酸盐岩油藏的开发中由于普遍面临着地层渗透率低、原油粘度大等不利因素。所以将大功率的振动波与酸化压裂技术相结合,将是一种十分有效的方法,文章通过研究认为它可以促进原油粘度的降低,提高地层的导流能力,有效的解决常规方法不能解决的问题,对于提高碳酸岩油藏中稠油、高凝油的产量有重要的指导意义。

关 键 词:振动波  振动增产  酸化压裂  普通酸压  深度酸压

Abstract:The vibration oil-producing and acid frac turing techniques are the feasible stimulating ways in oil and gas field development. The former is to treat the oil reservoir by vibration waves, i. e. to increase oil well productivity so as to raise reservoir ultimate recovery factor through making up fractures by fracturing and reducing crude oil viscosity, and the latter is a commonly-used oil well stimulation of car bonate reservoirs which is, through pumping into hydrochlo ric acid at over breakdown pressure, to make up fractures or to open up the natural fractures, and , through the acidizing fluid's flowing in the open fractures and reacting with frac ture surface from beginning to end, to form finally the frac tures with a certain length and a certain acid etching flow guiding ability, thus raising the percolation capability of the reservoir. Because some unfavourable factors as low forma tion permeability and high crude oil viscosity, etc, have been generally faced in developing the carbonate oil reservoirs con taining viscous crude and / or high solidification point oil, it will be a very effective method to combine large power vibra tion waves with acid fracturing technique. Through investi gation, it was considered that this method may reduce crude oil viscosity, raise formation flow guiding ability and solve the problems which can' t be solved by the conventional methods, so that it is of great importance to increasing pro duction of the viscous crude and / or high solidification point oil in carbonate oil reservoirs.
