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。
Based on the analysis of the seismics, geology, drilling, well logging, testing and production data of 58 wells in the Shaximiao Gas Reservoirs on the Xinchang Gas Field, the authors make full use of certainty (PostStack / PAL, Strata, Rave, Integralplus, Stratimagic and Jason modeling new technology, a new method for comprehensive and detailed three-dimensional quantitative characterization of reservoirs, the establishment of gas reservoir J2 s2 1, J2 s2 2, J2 s2 3, J2 s2 4 four sets of storage The three-dimensional reservoir reservoir parameters (porosity, permeability, water saturation) model with grid size of 20m × 20m × 1μs (2m) improve the accuracy of reservoir description and improve the original Reservoir prediction in the interwell interpolation deficiencies. It provides reasonable technical support for the reconstruction of various reservoirs in the Xiasha Miaoxi Gas Reservoirs and the rational utilization of proven reserves, which provides a reliable basis for the development and deployment of gas reservoirs.
