丘东气田西山窑组气藏储层气水关系评价

EVALUATION ON GAS-WATER RELATIONS OF GAS RESERVOIR OF XISHANYAO FORMATION IN QIUDONG GAS FIELD

丘东气田西山窑组砂体比较发育,为含气主要层段,目前西山窑组气藏已经得到了全面开发,但受砂体分布未落实以及储层气水关系认识不清,气藏挖潜有待提高。利用测井资料对该区西山窑组地层进行精细小层对比基础上,建立了西山窑组储层孔渗饱模型,并结合试油资料从新对气水分布规律进行了刻画,找到了未开发潜力气层分布有利区,为油田上产提供有力的技术支持。

Xishanyao formation in Qiudong Gas Field, with relatively well developed sand body, is the main gasbearing formation which has been generally exploited so far, though the potential development limited by the lackin knowledge of sand body distribution and gas-water relations of the reservoir still needs to be promoted. Basedon detailed substratum correlation of Xishanyao formation in this area with the utilization of logging information,this paper establishes a model of porosity, permeability and saturation for the correspondent reservoir and findsfavorable zones of unexploited potential gas reservoirs by restating the laws of gas-water distribution with thehelp of oil testing information, all of which helps to provide technical support for the oilfield production.
