压裂水平井见水阶段产量递减规律研究
Study on Production Decline Regularity of fractured Horizontal Wells during the Period of Water Break - through
摘要
Abstract
The production decline models of fractured horizontal wells during water break - through period is established and production decline regularity and influence factors are analyzed based on the feature of relative permeability curves of low permeability reservoirs , material balance principle and the productivity equations of fractured horizontal wells. The results of the study show that the higher the production rate in initial period, the more rapid the production decline; production decline is characteristic of the feature of stage by stage, that is, production declines rapidly in the first stage, declines gradually in the late stages, declines in exponential mode and the exponential index gets less in late stage than early stages; the feature parameter of relative permeability curves not only determine the decline speed and decline magnitude in the first stage, but also influence accumulative production; the stages of no water break - through and in low water cut are the main production stages for fractured horizontal wells.关键词
