摘　　要：柯克亚凝析气田上油组西四二-西五一气藏是低渗透凝析气藏。为了合理开发该类气藏,进行了布井方式和水平井开采对比研究。在保持西四二-西五一凝析气藏构造主体格局、储集层基本特征与流体相态性质不变的前提下,建立相似的高低渗透混合分布的理想模型。数值模拟研究表明,在相对高渗区布井既有利于高渗透区油气的采出,也有利于低渗透区油气的采出;水平井的单井产能高,生产压差小,可明显提高干气采收率和凝析油采收率,并有效缩短开采年限。X42-X51 reservoir of Kekeya condensate gas field is a low permeability gas reservoir. For rational exploitation of this reservoir, the exploitation methods such as suitable well pattern and horizontal drilling technology are studied. On the premise of the main structural framework, basic reservoir characteristic and original fluid phase behavior property of X42-X51 condensate gas reservoir, an analogy model for high and low permeability-mixed distribution is developed. Applying numerical simulation technology, the methods for exploitation of the condensate gas reservoir with low permeability are studied. The results show that location of well in high permeability area benefits the production of both high permeability area and low permeability area; horizontal well/drilling is of high productivity and low pressure difference, hence, the recovery of gas or condensate could be enhanced obviously and the development period of such field be effectively reduced.
