废弃压力是准确计算气藏采收率和可采储量的基础和前提。二项式产能方程法评价气藏废弃压力能够反映出气藏原始压力、气藏埋深、储层非均质特征、以及不同废弃条件等多种因素对于废弃压力的影响,因此该方法评价结果较传统废弃压力评价方法如经验法、气藏埋深法等更可靠。针对二项式产能方程法在求解参数过程中存在的难点,对该方法进行了迭代改进,并编写了相应程序,提高了计算效率及精度。 Abandonment pressure is the basis and premise for accurate calculation of gas recovery rate and recoverable reserves. Binomial productivity equation evaluation of gas reservoir pressure can reflect the original pressure of gas reservoirs, gas reservoir depth, reservoir heterogeneity, and different waste conditions and other factors on the impact of waste pressure, so the evaluation results of the method The traditional method of evaluation of abandoned pressure such as empirical method, buried depth method is more reliable. Aiming at the difficulties in solving parameter process of binomial productivity equation method, the method is improved iteratively and the corresponding program is written to improve the calculation efficiency and precision.
