红河油田37井区IPR曲线研究及合理生产参数确定

The research of IPR curve and determination of production parameters in Honghe 37 well area

低渗透油藏压裂水平井开发的显著特点是存在启动压力梯度、应力敏感以及裂缝参数影响等现象,这种特有的现象使该类油藏与常规油藏的生产特征存在较大差异,且目前无针对低渗油藏压裂水平井生产参数的优化设计模型,使得合理生产参数确定困难。本文将IPR曲线理论应用于水平井开采的动态分析中,通过实际生产数据进行分析得到的结果可靠,说明应用IPR曲线理论能有效评价预测油井产能和确定油井允许的最小流压界限及合理生产制度,为充分发挥油井生产能力、合理高效开发红河油田低渗透油藏提供了理论依据。

Abstract ：The significant characteristics of horizontal wells with hydraulic fractures for low permeability reservoir is starting pressure gradient, stress sensitivity as well as the impact of fracture parameters. Such a phenomenon unique to the type of reservoir and production characteristics of the conventional reservoirs are quite different, and currently no optimized design model for fractured horizontal wells production in low permeability reservoir ,therefore determine reasonable production parameters difficult. This paper IPR curve theory is applied to the dynamic analysis of horizontal wells, and actual production data by analysis of the results is reliable. This shows that application IPR curve theory can predict oil well production , and determine the oil well to allow the minimum flow pressure boundaries and reasonable production system can effectively evaluate well production capacity. The research of this paper to give full play to the well production capacity, the rational and efficient development of the Hong he oil field provides a theoretical basis for low permeability reservoirs.
