THE FACTORS AFFECTING THE PRODUCTIVITY OF HORIZONTAL WELL

Hu Dong-hui (Petroleum University, Dongying 257062, Shandong Province)  
In this paper, four methods for calculating the productivity of horizontal wells were reviewed, and the modified equations were given for the horizontal wells with anistropy of reservoir permeability, well eccentricity and formation damage. The factors affecting the productivity, such as reservoir thickness, horizontal well length, the anisotropy ratio of reservoir permeability, well eccentricity and formation damage on the productivity of horizontal wells were quantitatively an3lyzed by means of some calculation example and field data. It is shown from the analyzed results that formation damage is generally the major factor affecting productivity of horizontal wells. However, other influence factors should not be ignored in many cases.
