Geophysical and Hydrodynamic Studies of Multilateral Wells

The paper presents the study of multilateral horizontal wells. The complexity of solutions for the development of monitoring tasks in horizontal wells on the results of geophysical investigations associated with multiphase flow, the influence of the gravitational redistribution over the cross section of the well the phases at different speeds phase currents, not the monotony of the borehole trajectory (the presence of ascending and descending sections in the column). The phase inhomogeneity arises as the cross section and along the length of the well. In these conditions, the use of standard technologies and equipment are inefficient. In addition to the problems expressed above is necessary to ensure the delivery of a geophysical instrument in horizontal wellbore. The geometry of the filtration flow of multilateral horizontal well has a different look than in the vertical, providing a significant impact on the process of redistribution of pressure in the well and the accuracy of calculation of hydrodynamic parameters of the formation. It is necessary to use a special multi-sensor equipment allows to fix the composition and rate of fluid flow on the cross section of the well
