Technical and Economic Limits for Horizontal Well Development of Heavy Oil Reservoir in Shengli Oil Field

Abstract

Abstract: The result of horizontal well development of heavy oil reservoir is not only influenced by the conditions of reservoir and the design parameters of horizontal well, but also restricted by present oil price. This paper presents the statistical analysis of the field data from Shengli oil field, numerical simulation and economic evaluation, and then proposes the technical and economic limits for the horizontal well design in such a reservoir in condition of present oil price and technological level: the buried depth of reservoir is less than 1 500 meters; the degassed crude viscosity at 50℃ is lower than 30 000 mPa·s; the pay zone thickness is greater than 3 meters; the length of horizontal section is less than 300 meters; the vertical position apart from the top of pay zone is determined by 2/3.

Key words: Shengli oil field, heavy oil reservoir, buried depth, crude viscosity, pay zone thickness, technical and economic index
