Optimization of Horizontal Section Length of Horizontal Wells in Different Sedimentary Microfacies Zones

Ecuador Oriente Napo group of upper cretaceous basin P oilfield TmTS layer for tidal shelf sedimentary system, sedimentary microfacies types are mainly tidal channel, tidal sand ridge, tidal sand dam, continental shelf, shelf mud sand beach, plane distribution of sand body is complex and reservoir properties have bigger difference, now the oil field adopt vertical well and deviated well development, to improve the efficiency of development, The length of horizontal section of horizontal well is optimized according to the difference of sand body development in different sedimentary microfacies. On the analysis of the different sedimentary micro facies of reservoir and reservoir property on the basis of actual production data, carried on the fine sand body types, at the same time the numerical reservoir simulation analysis software Rubis mechanism of different sand body model is set up, the stable fixed number of year, the cumulative production parameters, such as, this paper compares and analyzes the different sedimentary micro facies of the optimal horizontal section length, improve the effectiveness of the horizontal well development, It can provide reference for subsequent well location deployment.
