【摘要】：本文在充分搜集龙虎泡地质信息的基础上,分析区域概况,进一步研究了不同渗透率级别储层的产量递减率、区块含水率、综合含水率、含水上升率以及压力的变化规律。最终通过对龙虎泡主体区块开发数据的分析预测出合理采油速度、合理注采比及合理注采比指数的界限值,把握龙虎泡开发区高含水期的开发规律,在此基础上,研究高含水后期开发技术政策界限是否应用于高含水期。应用油藏工程理论、物质平衡理论以及经济学理论对龙虎泡开发区块技术界限进行研究,指导油田下一步的生产实际工作。利用VB语言编程进行数据处理,对每口井进行小层的产量劈分,得出产量递减率的变化规律。利用已经计算出的单井产液量和各小层产液量,得出综合含水率的变化规律。运用卡彼托夫衰减方程,计算出合理采油速度。运用Logistic旋回模型建立注采比关系式,求得不同渗透率级别的合理注采比。通过求得弹性产率和水侵系数代入到注采比计算公式中,得到注采比的计算公式,将时间和相应的地层压力、采液速度代入公式,即可得到注采比。
[Abstract]:On the basis of fully collecting geological information of Longhu bubble, this paper analyzes the general situation of the region, and further studies the variation law of production decline rate, block water cut, comprehensive water cut, water cut rise rate and pressure of reservoirs with different permeability levels. Finally, through the analysis of the development data of the main block of Longhu Pao, the reasonable oil production speed, the reasonable injection-production ratio and the limit value of the reasonable injection-production ratio index are forecasted, and the development law of the high water-cut period in the Longhupu Development Zone is grasped, and on this basis, To study whether the technical policy limits of high water cut late development should be applied in high water cut period. Based on reservoir engineering theory, material balance theory and economic theory, the technical boundary of Longhupu development block is studied to guide the production practice of oil field in the next step. By using VB programming language to process the data, the production rate of each well is split and the law of production decline rate is obtained. The variation law of comprehensive water cut is obtained by using the calculated liquid production of single well and the liquid production of each small layer. The reasonable oil recovery velocity is calculated by using the Kapitov attenuation equation. The relationship between injection and production ratio is established by using Logistic cycle model, and the reasonable injection-production ratio of different permeability levels is obtained. By calculating elastic yield and water invasion coefficient into the formula of injection-production ratio, the formula of injection-production ratio is obtained. The injection-production ratio can be obtained by inserting time, formation pressure and liquid velocity into the formula.
