The reasonable length of horizontal wells for lens-like thin-layered bottom-water reservoirs has been a question

and there were limited studies in the literature. Aiming at the study of a specific low amplitude

moderate-high permeability

thin lens-like sandstone reservoir with bottom-water in Hutubi river layer in Luliang oilfield of Xinjiang

by using a variety of methods in geology

drilling

reservoir engineering and numerical simulation

and combined with the effects of horizontal wells during the reservoir development

we demonstrated the relation respectively between various factors of horizontal well length and wellbore pressure loss

reservoir adaptability

and development of oil drilling rate effects of such reservoir. Then

we proposed the range of the reasonable length of horizontal wells considering both theoretically and practically. The results showed good reliability and applicability

providing technical reference for the research and application of horizontal wells in similar bottom-water reservoirs.
