摘要:

井间干扰是实现煤层气稳产高产的有效技术措施。 目前,煤层气井间干扰的理论研究较多,准确量化的现场认识较少。 根据煤层气井排采的特点,提出了一种方便、可靠、高效的用于判断井间干扰现象及定量计算井间干扰程度的新方法,该方法利用现场观察到的煤层气井启抽水位与原始水位存在的明显差异,定量化煤层气排采降压过程中出现的井间干扰现象。 通过在保德区块的实际应用,对比了所提出方法与煤层气理论判断方法的优缺点,并验证了所提出方法的可靠性,得出了该区块井间干扰特征的定量化认识,同时提出了井间干扰规律在合理部署井位、提高产气速度、缩短见气时间及优化排采制度等方面的应用建议。

Abstract:

 Well interference of coalbed methane wells is a kind of effective technologies to achieve high and stable gas production rate. At present, there are many studies on the interference phenomenon of coalbed methane wells, but less quantification work of wells interference in the field. According to the drainage features of coalbed methane wells, this paper proposed a new convenient, reliable and efficient method to determine and quantify the wells interference phenomenon, which is on the basis of the difference between observed start-pumping water level and original water level of coal bed methane wells. During the drainage process, the interference phenomenon of coal bed methane wells can be quantified more precisely by the new method. By comparing the results of the proposed method and theory method in the real case in Baode block, the reliability of the proposed method was verified. By the new method, the quantified characteristics and rules of interfered coal bed methane wells in Baode Block were summarized. Hence some reasonable application suggestions of interference of coalbed methane wells were provided, such as proper arrangement of well placement, increase of gas production rate, shortage of gas breakthrough period and optimization of production system.
