油气上窜速度计算方法改进及应用

Improvement and Application of Oil and Gas Upward Channeling Speed Calculation Method

油气上窜速度反映了钻开油气层能量的大小,其准确与否直接关系到钻井施工的井控安全,也与评价和保护好油气层有密切的关系。通过对油气上窜速度计算方法影响因素的分析,结合现场实际,从如何优化关键参数出发,提出了完善油气上窜速度计算的具体方法和措施。修正后的计算公式更能准确反映油气侵入程度,也为调整钻井液密度、保护油气层提供更可靠依据。

The oil and gas upward channeling speed reflects the energy of drilling oil and gas reservoir, and its calculation accuracy is directly related to well control safety in drilling construction, and it is closely related to the evaluation and protection of oil and gas reservoirs. Based on the analysis of the influencing factors of the oil and gas upward channeling speed calculation method, the concrete methods and measures to improve the calculation accuracy of oil and gas upward channeling speed are put forward. The improved formula can more accurately reflect the degree of oil and gas invasion, and provide a more reliable basis for adjusting drilling fluid density and protecting oil and gas reservoirs.
