Abstract

Abstract:

Accurately predicting period of heating steam stimulation area of horizontal well is very important for the development
of heavy oil reservoir. The current forecast radius formula contains a double integral，which makes the calculating process
complicated and time consuming. In this paper，by Marx Langenheim vertical well heating range formula as the theoretical
basis，and on the basis of in-depth study，we simplified calculation of heating model，and established a simplified model of
horizontal well cyclic steam heating，which is with simple relationship type，easy to solve and convenient to apply. Oilfield
actual parameters are calculated and analyzed，and the results show that using the improved formula can get relatively accurate
result，which verifies the accuracy of the formula.

Key words: horizontal well, cyclic steam stimulation, heating area, predicting models
