| Abstract: | Summarizing the designing and drill experience of horizontal wells in the old area of Daqing Oilfield, it is derived that the main factors influencing the prediction accuracy of the top microstructure of sand bodies include: sedimentary microfacies, boundaries of sedimentary units,measurement accuracy of well head elevations and deviation of nearby vertical holes.According to contrast research of two horizontal wells in the old area of Daqing Oilfield, the prediction accuracy of the microstructure due the difference in geology conditions and well density influences designing, drilling and construction, and on that of the top microstructure of sand bodies determines the feasibility of horizontal designing and the success rate of horizontal drilling in the old area of Daqing. |
| Keywords: | microstructure horizontal well trajectory design Daqing |
