Abstract:Aiming at the problem of determining the position of the water production of the horizontal well in the heavy oil reservoir with bottom water, this paper establishes the physical and mathematical model of the bottom water heavy oil reservoir, using the Green function, the Newman product method, and the superposition principle to derive the non-horizontal well in the bottom water heavy oil reservoir. The Stehfest numerical inversion algorithm was used to obtain the bottom fluid pressure solution of the horizontal well production in the bottom water thick oil reservoir with the wellbore storage effect and skin effect. By drawing a typical plate for horizontal well testing in stages, and dividing and analyzing the flow stages, the influence factors of different production lengths, number of production sections, position distribution of production sections, and flow distribution are obtained, and relevant explanatory plates are drawn. The field application examples verify the validity of the research results and broad application prospects.
Keywords:Bottom water heavy oil reservoir   Horizontal well   Water production position   Well test interpretation   Plate
