赤岸油田韦2断块裂缝分布研究及应用

Research and application of fracture distribution of Wei 2 fault block in China oilfield

低渗透油藏开发是目前各油田普遍关注的难题,国内近几年的石油地质储量增长主要在Ⅲ类低渗透砂岩储层。致密低渗透储层中裂缝分布的研究,对提高低渗透储层的开发效果具有重要的理论及现实意义。该文针对韦2断块的实际地质特征,运用裂缝分布研究方法开展裂缝分布的初步研究及预测,为油藏合理开发提供有关地质模型。

Exploitation of the reservoir with low permeability is at present a difficult problem that is general concerned in all oilfields. At home in these days main increase of OIP is the third genus reserve of the sandstone reservoir with low permeability. The research of the fracture distribution of tight lowpermeability reservoir has very important theoretical and practical significance on development effect of the reservoir. With regard to the practical geological feature of Wei 2 fault block, the study method of fracture distribution is used in the preliminary study and forecast of fracture distribution so as to offer relevant geological model for reasonable exploitation of oil reservoir.
