复杂边界油气藏中水平井的产能公式——齐成伟公式的应用范围研究
|
摘要
针对复杂边界油气藏中分支水平井的产能预测问题进行了深入研究。将圆形油气藏径向等分,即将齐成伟建立的圆形油气藏中辐射状分支水平井拟三维产能公式中的Q替换为nQ后,得到了扇形油气藏中水平井的拟三维产能公式。将带形油气藏纵向等分,即将齐成伟建立的带形油气藏中横向水平井拟三维产能公式中的b替换为2b、L替换为2L、Q替换为2Q后,得到了带形油气藏中顶壁横向水平井的拟三维产能公式。将带形油气藏横向等分,即将齐成伟建立的带形油气藏中纵向双分支水平井拟三维产能公式中的Q替换为2Q后,得到了半带形油气藏中离壁纵向水平井的拟三维产能公式;进一步将si替换为0、so替换为L/2后,得到了半带形油气藏中顶壁纵向水平井的拟三维产能公式。
This paper presents an in-depth analysis of productivity prediction of multi-lateral horizontal wells in fault block reservoir.By radially sectioning circular oil or gas reservoir into sectors of equal magnitude,i.e.by substituting nQ for Q in Qi Chengwei's pseudo-3-D productivity formula for radial multi-lateral horizontal well in circular oil or gas reservoir,a pseudo-3-D productivity formula for horizontal well along the angle bisector in sectoral oil or gas reservoir can be derived.By longitudinally sectioning ribbony oil or gas reservoir into two equal parts,that is,by substituting 2b for b,2L for L and 2Q for Q in Qi Chengwei's pseudo-3-D productivity formula for transverse horizontal well in ribbony oil or gas reservoir,a pseudo-3-D productivity formula for transverse horizontal well to-the-side-wall in ribbony oil or gas reservoir can be derived.By transversely sectioning ribbony oil and gas reservoir into two equal parts,that is,by substituting 2Q for Q in Qi Chengwei's pseudo-3-D productivity formula for longitudinal bilateral horizontal well in ribbony oil or gas reservoir,a pseudo-3-D productivity formula for longitudinal horizontal well off-the-middle-wall in half ribbony oil or gas reservoir can be derived.Further substituting 0 for si and L /2 for so,a pseudo-3-D productivity formula for longitudinal horizontal well to-the-middle-wall in half ribbony oil or gas reservoir can be derived.
