识别多裂缝水平井中每个裂缝簇中每个裂缝的贡献可能颇具挑战性；然而，了解裂缝簇级连通性可以为优化完井设计和井距提供详细指导。本研究提出了一种新方法，用于解释远场应变变化和压力数据，以量化裂缝簇级连通性和特性。
在本研究中，作者首先分析了美国能源部水力压裂试验场 (HFTS)-1（三期）井干扰测试期间的应变和压力响应。基于一维线性流动方程的假设，开发了一个新模型来描述生产过程中裂缝的早期压力变化。通过结合压力、应力和应变之间的线性关系，该模型得到了扩展，以捕捉裂缝沿线的应变变化。随后，该模型被用于解释压力计数据和相应的应变测量值，验证了其准确性。
Identifying the contribution of each fracture from each cluster in a multifractured horizontal well can be challenging; however, understanding fracture connections at the cluster level can provide detailed guidance for optimizing completion designs and well spacing. This work proposes a new method to interpret far-field strain change and pressure data to quantify fracture connectivity and properties at the cluster level.
In this study, the authors first analyzed strain and pressure responses during a well interference test in the US Department of Energy’s Hydraulic Fracturing Test Site (HFTS)-1 (Phase III). Based on the assumption of a 1D linear flow equation, a new model was developed to describe early-time pressure changes in the fracture during production. By incorporating the linear relationship between pressure, stress, and strain, the model was extended to capture strain variations along the fracture. The model was then applied to interpret pressure gauge data and corresponding strain measurements, validating its accuracy.
