油井措施投入决策是油藏经营管理中的重要内容,矿场上现行的措施增油量计算方法存在明显不足,在很多情况下不能正确反映每次油井措施的真实增油量,严重影响了油井措施效果和效益分析评价工作的进行。本研究提出了油井措施真实增油量的计算方法,新方法考虑了不同日期实施的措施间的相互影响,并可进行任意时间段内的措施增油量分析,以大港某油田2002年56井次9类油井措施的计算为实例,证明新方法客观、真实地反映措施的实际效果和措施的实际经济效益,有助于科学指导措施投入决策,以效益的观念经营管理油藏。

Decision making of oil well stimulation treatments is very important in world oil reservoir management, however the present method on calculating the oil production increment exhibits some defects and cannot reflect the real production increasing. A new method is present here which takes the correlation between the stimulation treatments implemented on different date into consideration, and oil production increment in any time period can also be analyzed. The calculation of production increment in June 2002 of Dagang Oilfield is taken as an example, and it shows that the new method is subjective and can reflect the actual effects and economic benefits produced from stimulation treatments.
