摘要
渤海JX油田油层厚度大、层间非均质性强、地下原油黏度大,水驱开发过程中易发生层间干扰及边底水锥进现象,严重影响油井的产能。通过理论分析和数值模拟等手段,研究了海上复杂厚层稠油油藏开发井网,深入剖析了厚层稠油油藏细分开发层系的必要性及水平井的关键参数。应用实践及效果评价表明利用水平井细分开发层系开发厚层稠油油藏效果良好。
Bohai JX oilfield is a complex thick layer of heavy oil reservoir, with characteristics of high reservoir thickness and strong interlayer heterogeneity, which would result in interlayer interference, edge and bottom water coning in water flooding process, so the oil well productivity can be influenced seriously. In order to develop this thick heavy oil reservoir efficiently, the geological model is established by means of theoretical analysis and reser- voir numerical simulation, and then the necessity of subdivision development of thick heavy oil reservoir and key parameters of offshore complex heavy oil reservoir are studied. Practice and effect evaluation show that subdivision of layer series by horizontal wells has good effect in the development of thick heavy oil reservoirs.
