【摘要】:随着油田开发的深入,常规油田开发已经不能满足社会对油气的需求,因此需要寻找油田开发后备潜力,低孔低渗透断层~岩性油藏成为勘探开发增储增产的重点。杏北开发区扶杨油层为低孔特低渗透断层~岩性油藏且具有较大油气潜力,需要开展扶杨油层的油藏评价工作。论文研究区按照物性差异可以划分为三类潜力区:Ⅰ类潜力区、Ⅱ类潜力区、Ⅲ类潜力区。为落实扶杨油层开发潜力及注水可行性,杏北开发区开展了扶杨油层Ⅰ类潜力区杏B1井区开发先导性矿场试验,试验表明杏北扶杨油层Ⅰ类区块注水开发是可行的,但杏B1井区规模小,注采井网不够完善,对扶杨油层Ⅱ类潜力区研究程度不够。因此论文针对扶杨油层Ⅱ类潜力区杏A1井区进行深入研究。本文首先深化对扶扬油层地质特征认识,形成了标准层控制下的溢岸薄层砂细分对比技术,油水层识别技术,储层变参数解释方法;在此基础上,确定超前注水技术界限,优化油水井压裂技术,分析研究了适合于杏北扶扬油层的综合配套技术方法,落实扶杨油层开发潜力,探索扶杨油层经济有效开发模式。研究结果表明,地质分析前提下的油层动用开发技术以及超目前注水、综合压裂技术可以较好的指导扶杨油层开发工作,为油藏经济有效开发提供了成功技术经验,提高了开发的经济效益,对长垣老区扶杨油层有效开发动用也具有一定的指导意义。
[Abstract]:With the deepening of oilfield development, conventional oilfield development can no longer meet the needs of the society for oil and gas. Therefore, it is necessary to search for the reserve potential of oilfield development, and low porosity and low permeability fault ~ lithologic reservoir becomes the focus of exploration and development to increase reservoir production. Fuyang reservoir in Xingbei Development Zone is a low porosity and low permeability fault ~ lithologic reservoir with great oil and gas potential, so it is necessary to carry out reservoir evaluation of Fuyang reservoir. According to the difference of physical properties, the study area can be divided into three types of potential regions: type 鈪,
