Case study shows that considering the geologic parameter uncertainty allows the gas well productivity estimation to be more precise , thus decreasing the possible risks in gas pool development 实例计算表明，考虑地质参数的不确定性能够使气井产能评价更准确，并能降低气藏开发存在的风险。
Horizontal well production forecasting formulas need to consider not only anisotropism and borehole eccentricity , but also the skin factor during drilling and completion process 摘要水平井产能预测公式除了要考虑储层各向异性和井眼偏心距的影响因素外，还要考虑钻井和完井过程中产生的表皮系数的影响。
On the basis of comparing various productivity calculation formulas , the authors put forward the productivity calculation method for the horizontal well of condensate gas reservoir , which proves a high accurate rate in the cases 在比较了适合于油藏水平井产能计算公式的基础上，提出了凝析气藏水平井产能计算方法，通过实例计算，正确率较高。
Based on sand control well productivity prediction , the economic effect evaluation and economic index comparison to all feasible methods in the viewpoint of technology are conducted , and optimum sand control method is synthesized and optimized , which is reasonable in technology , and feasible in economy 摘要在防砂井产能预测的基础上，对所有技术上可行的防砂方法进行经济效果评价和经济指标对比，综合优选出技术上合理、经济上可行的最佳防砂方法。
It is suggested that because the volcanic reservoir has very high heterogeneity , waterflooding process should not be adopted rashly in the early production period until obtaining experiences from clustered - well lest : infill drilling and adjustment during the period of early production may enhance producing extent , prolong water - free oil production period and improve performance response : a number of horizontal wells drilled during the mid - period of production may further increase the single well productivity and keep relatively long - term production stable and high 指出，由于火山岩储集层非均质性极强，在火山岩油藏开发初期切不可贸然采用注水开发，应在实验井组中取得经验后，方可逐步推广；开发初期，实施加密井调整措施，可提高储集层动用程度，延长油藏无水开采期，改善开发效果；开发中期钻一定数量的水平井，可进一步提高单井产能，使油藏保持较长期的稳产、高产。
