有邻井干扰压力恢复处理技术

在气井生产早期,由于开采时间短,所在储层渗透率低,压力变化的波及范围很小,通常的解析试井方法能够进行很好的解释;但是随着气井的不断生产,影响范围越来越大,部分井产生了井间干扰,通常的解析试井解释这些资料时,常常解释为边界影响,从而对储层产生错误的认识。因此我们研究数值试井,以正确解释有邻井干扰的压力恢复资料。本文从如何判断存在邻井干扰的资料入手,提出了存在邻井干扰时的表现特征,以及成功对这类试井资料解释处理。这对进一步完善试井解释技术、提高试井技术的应用水平和效果有很大促进作用。

Treat methods of adjacent wells interence pressure recovery

In the early days for produce of gas well,because of the short time for produce, low permeate of reservoir bed and the low range of pressure to involve,we can explain the well data perfectly with the normal order of explain.Along with the production of gas well, the higher range of pressure to involve,part of gas wells come into existence with neighborhood,the result for the normal order of explain comes into influence of boundary, for this reason,we recognize the reservoir with wrong knowledge,n order to explain the well data with influence of boundary,we study well test order of numerical value definitely.To start with the well data of existence with neighborhood,we analyses the characteristic of wells with existence of neighborhood and explain the data definitely.What we have done gets forward to the technology for data of well test and explain,and to heighten the apply of well test obviously.
