柯克亚凝析气田X8段非均质凝析气藏储量精细计算

Subtly Calculation of Reserves of Anisotropic Condensate Gas Pool of X8 Section in Kekeya's Condensate Gas Field

塔里木盆地柯克亚凝析气田X8段凝析气藏为陆相沉积,现有各种地质、生产资料均表明该气藏储层非均质性较强,工程上采用动态法计算的X8段凝析气藏地质储量不足其勘探储量的一半。为尽量避免储层非均质性影响储量计算的精度,在采用容积法对非均质油气藏进行储量计算时应仔细研究储层非均质性,细分储量计算单元,精确求取储量计算的各个参数。

The X8 section gas pool of Kekeya condensate gas field in Tarim basin is of continental deposit.All the data of geology and production proves that the gas pool has strong heterogeneity.In fact,the reserve calculated by dynamic method in engineering is only as half as the exploration reserve.When volume method is used for reserve calculation,the effect which heterogeneity has on reserve calculation should be reduced,the reservoir heterogeneity needs to be studied carefully,calculating elements to be subdivided and each parameter to be obtained precisely.
