Abstract

Abstract:

In general case, the actual finishing drilling horizontal well is not absolutely horizontal, the well trajectory is undulant as wave. When the wellbore bending degree is big, gravitational potential energy causes the bigger difference of inflow performance than the ideal horizontal wells. Therefore, it is necessary to do in-depth analysis of the horizontal well inflow performance. The horizontal well with curved trajectory was approximately regarded as a continuous structure which is composed of a series of slant wells. By using the reservoir-wellbore flow coupling semi-analytical model, this paper studied the effects of well trajectory bending on horizontal well inflow performance, and compared the calculation results with the multi-branch horizontal wells. The result shows that well trajectory bending will affect the productivity of horizontal wells and wellbore pressure distribution, the radial inflow curves of horizontal wells and multi-branch horizontal wells have a big difference with ideal situation, and the shape fluctuates with well trajectory changes.
