Main factors influencing reformation effects of massive acid fracturing reservoir

摘要: 塔河油田碳酸盐岩缝洞型油藏储集空间复杂,70%的油井需要酸压建产,部分油井因埋藏深、地温高,原有的酸压规模小,裂缝穿透距离有限,不能有效沟通储集体,导致油井供液不足,低产低效。通过对已实施油井分析研究得出影响大型酸压效果的主要因素为(1)油井所处井区油气富集程度;(2)油井控制区域储集体发育程度;(3)前期酸压沟通储集体状况;(4)压裂施工规模及参数。Abstract: Fractured-vuggy carbonate reservoirs in the Tahe Oil Field are complicated.Acid fracturingis required in 70%of the wells.In some wells with deep burial depth and high formation temperature,the former acid fracturing failed to connect reservoir effectively since fractures had not penetratedenough far away,resulting in feeding-flow lack,low yield and inefficient.Main factors influencingreformation effects of massive acid fracturing reservoir have been concluded as follows:a)Petroleumenrichment extent of the region where wells locate;b) Reservoir generation degree of the well-control-ling region;c) Reservoir connection condition after the former acid fracturing;d) Scale and parametersof acid fracturing.
