本文通过对特拉华盆地沃尔夫坎普深层凝析油生产井进行现场建模研究，采用含水力压裂的成分模拟模型，研究了凝析油堤对油井动态的影响。模型发现，凝析油堤的影响微乎其微；凝析油主要在裂缝网络中析出，可通过高导流裂缝高效开采。本文提出了一种采用积极返排策略的最佳开发方案，该方案已通过二叠纪盆地凝析气井实际运行验证，有望在不产生凝析油堤风险的情况下提高项目价值。
过去几十年来，特拉华盆地一直采用水平井开发，目标是Bone Spring和Wolfcamp地层。作业公司于2023年末钻探了两口评价井，以测试新墨西哥州A油田深层Wolfcamp地层。本研究的主要目的是分析井间距、叠合方案、完井设计和压降策略对井效的影响，以提高井产能和经济效益，从而优化深层钻井-井距-单元设计，使其与油田的开发目标相一致。
新墨西哥州 A 油田占地面积超过 14,000 英亩。
This paper investigates condensate-banking effects on well performance by conducting field-modeling studies on Delaware Basin deep Wolfcamp condensate producers using compositional simulation models with hydraulic fractures. The models found condensate banking to be of minimal concern; condensate dropped out mostly in fracture networks and could be efficiently produced through highly conductive fractures. An optimal development plan with an aggressive flowback strategy, validated by actual Permian Basin gas-condensate well performance, is proposed that should improve project value without condensate-banking risk.
In the past decades, the Delaware Basin has been developed with horizontal wells targeting the Bone Spring and Wolfcamp formations. The operator drilled two appraisal wells in late 2023 to test the deep Wolfcamp in New Mexico Field A. Key aims of this study were to analyze how well performance changes with well spacing, stacking scheme, completion designs, and drawdown strategy to improve well productivity and economics, thus optimizing deep-bench drilling-spacing-unit design, which aligns with field‑development goals.
New Mexico Field A covers more than 14,000 surface acres.
