TH油田凝析气藏水平井试井合理压差的确定

Determination of reasonable pressure difference for horizontal well test of condensate gas reservoir testing in TH Oilfield

水平井产能试井主要是求取产能方程和绝对无阻流量,优选生产油嘴。水平井试井合理压差的确定实际上是与水平井合理产能相对应,而合理的产能是通过选择合理的油嘴来实现的。产能试井设计中的关键就是设计合适的油嘴,以获得稳定可靠的产量和压力资料。

The horizontal well open-flow capacity, and to productivity test is mainly to obtain select nozzle for production. The the productivity equation and absolute determination of reasonable pressure difference for horizontal well test is relevant to the reasonable productivity which is determined by the selection of nozzle. The key of the well test design for productivity is to design reasonable nozzle in order to obtain steady and reliable productivity and pressure data.
