【摘要】 在对新场气田上沙溪庙组气藏 5 8口井的地震、地质、钻井、测井、测试及生产资料分析的基础上 ,充分运用确定性 (PostStack/PAL、Strata、Rave、RM、Integralplus、Stratimagic)和随机 (Jason)建模新技术、新方法对储层进行全面、细致的三维定量表征 ,建立了气藏J2 s2 1、J2 s2 2 、J2 s2 3 、J2 s2 4四套储层的三维空间储层属性参数 (孔隙度、渗透率、含水饱和度 )模型 ,网格大小为 2 0m× 2 0m× 1μs(2m) ,提高了气藏储层描述的精度 ,改进了原有储层预测在井间插值方面的不足。对上沙溪庙组气藏各类储层的改造及已探明储量的合理利用提供合理的技术支持 ,为气藏开发部署提供了可靠依据。更多还原

【Abstract】 On the basis of analyzing the data on seism ,geology,drilling,logging,testing and production collected from 58 wells in Uppe r Shaximiao Formation (J 2 s 2) gas reservoirs in Xinchang field,and by a pplying fully the new deterministic (Post Stack/PAL,Strata,Rave,RM,Integralplus, Stratimagic) and random (Jason) modeling techniques and methods,the reservoir ma y be characterized in detail,overall,three dimensionally and quantitatively and the 3-D reservoir attributive parameters (including porosity,permeability and w ater saturation) model with a network size of 20m×20m×1μs(2m) was set up f or each of the J 2 s 2 1,J 2 s 2 2,J 2 s 2 3 and J 2 s 2 4 gas reservoirs,thus raising the accuracy of reservoir descript ion and overcoming the shortcomings in the interwell interpolation method used f or original reservoir prediction,which provides reasonable technical support for the stimulation of various reservoirs and the reasonable utilization of the pro ved reserves in Upper Shaximiao Formation gas reservoirs,and supplies reliable b asis for gas reservoir development deployment.更多还原
