探测半径的计算公式

Calculated Formula for Investigation Radius

探测半径是评价油藏控制程度和井控储量的重要参数。现有的探测半径数学计算公式缺乏统一和规范性。为改变这一现状,更准确地计算油井的探测半径,以调研的大量相关文献为基础,从均质油藏直井、非均质油藏直井、水平井和特殊情形四个方面,对国内外学者在探测半径的研究进行总结和归纳,得到了这四方面的探测半径计算公式,提出了目前研究存在的问题和相应的解决思路,既便于科研工作人员对探测半径公式的查阅参考,又利于探测半径研究的发展和完善。

The investigation radius is the important parameter to evaluate the degree of control and well control reservoir reserves. The existing mathematical calculation formula for detection radius lacks of unified and standardized. In order to change this situation to calculate an accurate radius of well,based on research on a umber of related documents,from four aspects of vertical wells with homogeneous reservoirs,vertical wells with heterogeneity reservoir,horizontal wells and exceptional circumstances,the study on detection radius by scholars at home and abroad are summarized to achieve a detection radius formula at these four aspects and current research problems and corresponding solutions ideas are presented,which not only is convenient for research staff to consult reference probe radius formula,but also conducive to probe radius of research development and improvement.
