水平井在姬塬油田铁平7井区的应用效果研究
|
摘要
鄂尔多斯盆地伊陕斜坡西南部的铁平7井区油藏属于典型的底水发育的低渗透岩性—构造油藏,油藏具有油层厚度较薄,物性较差,单井产能较低的特点.通过对水平井与直井的应用效果分析对比后得出:水平井可以解决边底水突进过快的问题,并可增大泄油面积,提高单井产量,从而显著提高低渗透油藏产能,增加经济效益.
Located in the mid-east region of Yishan slope in Ordos basin,Tieping 7 wellblock is a typical low permeability reservoir with basal ground water. It is characterized as thin oil layer,poor physical property and low deliverability of single well. Comparative analysis of used horizontal and vertical wells shows that horizontal wells can slow down the side bottom water breakthrough,increase drainable area,and improve production of single well.So horizontal wells can be used to enhance productivity and raise economic efficiency significantly in low permeability reservoir.
