Abstract: Reservoir productive capacity forecast is one of the important content of reservoir evaluation, horizontal well logging interpretation is mainly through the contrast corrected technique of horizontal well conventional log curve and pilot well conventional log curve, adding to the traversing relation between horizontal well track and formation. Although a large amount of information about well track and formation relation can be provided to exploitation engineers with this method, production oil gas ability of the reservoir ,in the process of drilling the horizontal well, it is difficult to be pointed out. Which brings difficulty to development of the field .in this paper, based on conventional log material, well profile is divided with the sensitivity analysis
and cross plot technique, then the reservoir effective thickness is
derived. At the same time,analyzing pilot production data and calculating out the horizontal well production level under the normalization condition, favorable linear relationship between them is found and productive capacity prediction model between horizontal well daily oil production and reservoir effective thickness of XX line of oils in DS oil field is set up. All the research
mentioned above provides more reliable horizontal well logging interpretation to reservoir description.

Key words: horizontal well, the reservoir, productive capacity forecast, effective thickness, logging evaluation
