YQ2气区合理产量的研究

气井合理产量的研究是气井高效开发的一个重要课题。由于影响气井产能的因素很多,因此应用不同的研究方法,结论有很大差异。YQ2井区为致密气藏,目前处于开发初期,测试资料不完善且差异较大。为了高效、合理地开发气藏,确定气井的合理产量就成为了急需解决的研究课题。针对YQ2井区的地质特征和开发情况,本文对比分析了经验方法、生产指示曲线法、生产数据统计法和数值模拟法等计算合理产能的4种方法。通过对各种方法的分析评价,得出了各种方法的优缺点和适用性。建议根据气井的地质特征和动态特征综合考虑,选择合理的方法来确定气井的合理产量。

Methods of Determining Reasonable Production of Gas Well in YQ2 Gas Field

Determination of reasonable production of gas well is a significant research subject. Due to its many influencing factors, gas well production which is calculated by different methods could vary dra matically. YQ2 gas field belonged to tight gas reservoir only have limited testing information with very dif- ferent interpretation results now. In order to obtain rational and efficient development of the gas reservoir, determination of gas well production will become an urgent research. According to geological features and actual development situation of YQ 2 gas field, four methods of calculating gas well production are pro- posed in this paper. Through the evaluation of these methods, the advantage, disadvantage and suitability are obtained. All in all, reasonable production of gas well should be determined by choosing a rational method according to the combined consideration of geological features and dynamic development character- istics.
