摘要:

储气库注采井反复高强度注采,储集层频繁应力变化,易引发出砂,威胁储气库稳定运行。以鄂尔多斯盆地榆37储气库为例,运用节点分析法,考虑支撑剂运移的临界流速模型,结合地层出砂预测的临界出砂压差模型及临界冲蚀流量模型,明确榆37储气库注采井的合理注采区间,确保储气库在极限生产状态下的运行安全。结果表明:通过对储集层裂缝中支撑剂进行受力分析,建立裂缝中支撑剂启动的临界流速模型,计算出当注入速率与采出速率分别为10.89 m/s和8.19 m/s时,支撑剂达到临界启动流速;考虑3种限制性模型,对节点分析法进行改进,计算出榆43-1井安全运行的合理注采区间,分别为1.79×104~6.53×104 m3/d和2.82×104~6.35×104 m3/d;在安全的前提下,计算出榆37储气库10口井的合理注采区间。

Abstract:

Repeated high-intensity injection and production in wells of a gas-storage lead to frequent stress changes in the reservoirs, which may trigger sand production to threaten the stable operation of the gas storage. Taking the Yu-37 gas storage in the Ordos Basin as an example, the nodal analysis method was used, together with the critical flow velocity model for proppant migration, as well as the critical sand production pressure difference model for sand production prediction and the critical erosion flow model, to define the reasonable injection and production rates of wells for ensuring the operation safety of the Yu-37 gas storage under the extreme production state. According to the calculation using the critical flow velocity model for initiation of proppant migration in the fractures, which was established through the stress analysis of the proppant in the reservoir fractures, the proppant reaches its critical flow velocity for initiation of migration when the injection and production rates are 10.89 m/s and 8.19 m/s, respectively. Three restrictive models are used to modify the nodal analysis method, the reasonable injection and production rates of Well Yu 43-1 are determined to be (1.79-6.53)×104 m3/d and (2.82-6.35)×104 m3/d, respectively. Given the safety limits, the reasonable injection and production rates of 10 wells at the Yu-37 gas storage are defined.

Key words: Yu-37 gas storage, sand production, nodal analysis method, initiation of proppant migration, critical flow velocity, critical production pressure difference, erosion flow rate
