摘要:
水平井是渤海S油田开发后期的主力井型,但随着油田进入高含水开发阶段,井控储量逐渐降低,增加了对剩余油深入精准挖潜,对油井稳产策略精细制定,对后期油井开发指标精准预测的要求。国内外专家关于油田水平井关键指标研究的成果丰富,但大多没有具体到特定油田。对S油田水平井的含水上升模式进行研究,归纳总结出一套油田自适应的高含水期水平井关键指标预测技术体系。在近两年新投的4口水平井对新方法进行了可靠性验证,结果表明计算的相对误差在8%以内,说明依据S油田不同含水上升模式拟合的产量、含水及递减公式在油田内普遍适用,具有广阔的应用前景。
Abstract:
Horizontal wells are the main well type in the later development stage of the S Oilfield in the Bohai Sea. However, as the oilfield has entered the stage of high water cut development, the well control reserves gradually decrease, increasing the requirements for deep and precise tapping of remaining oil, fine formulation of well stabilization strategy, and precise prediction of late well development indexes. There are abundant achievements of domestic and foreign experts on the research of key indicators of horizontal wells in the oilfield, but most of them are not specific to a oilfield. It was studied the water cut rise pattern of horizontal wells in S Oilfield, and summarized a set of oilfield adaptive technical systems for predicting key indexes of horizontal wells in a high water cut period. The reliability of the new method was verified in four newly invested horizontal wells in the past two years, and the results showed that the relative error of the calculation was within 8%, indicating that the production and water cut formulas fitted according to the different water cut rising modes of the S Oilfield are generally applicable in the oilfield and have broad application prospects.
