Well Test Theory and Productivity Evaluation of Multilevel Fractured Horizontal Wells

Li Yue，Ji Dawei，Wang Jie

In order to realize the efficient development of the oilfield,it is needed to evaluate the productivity of the reservoir. According to the structure of horizontal well, the form of fracture and the distance of fracture, combined with the theory of seepage mechanics, a well test analysis model for multistage fractured horizontal wells considering wellbore storage and skin factor is established. A typical curve fitting chart of pressure and derivative is obtained, and a well testing interpretation software system based on the theoretical plate is developed. Based on the well test interpretation software system compiled by the theoretical plate, the IPR curve and the production decline curve are plotted by using multistage fracturing horizontal well test interpretation software.The results show that under the same production conditions, the influence of fracture distance and crack skin factor on productivity is less than the effect of crack half length on productivity. According to the curve of production flow rate with bottomhole flow at different production stages and the curve of output with production time at different bottomhole flow pressures, and the production capacity is predicted and evaluated at different stages of fracturing horizontal wells. It provides a strong guarantee for the efficient development of multistage fracturing horizontal wells.

摘要/Abstract

摘要： 为实现油田的高效开发，需要对储层的产能进行评价。根据井筒结构、压裂裂缝形态和裂缝距离，结合渗流力学理论，在考虑井筒储集和表皮系数的条件下，建立了多级压裂水平井试井数理模型，得出无量纲拟压力及其导数曲线拟合图版，根据理论图版编制出试井解释软件系统，利用多级压裂水平井试井解释软件，绘制出IPR曲线和产量递减曲线。结果表明，在生产条件相同的情况下，裂缝距离和裂缝表皮系数对产能的影响小于裂缝半长对产能的影响，通过不同流压下产量随生产时间的变化曲线，以及不同生产时期下产量与井底流压之间的关系曲线，对压裂水平井不同生产阶段进行产能预测评价，为实现多级压裂水平井高效开发提供了有力保障。

According to the curve of production flow rate with bottomhole flow at different production stages and the curve of output with production time at different bottomhole flow pressures, and the production capacity is predicted and evaluated at different stages of fracturing horizontal wells. It provides a strong guarantee for the efficient development of multistage fracturing horizontal wells.
