Slow Bottom Water Coning Horizontal Well Sand Control Completion Technology Research And Application

For Oil Production Plant of Shengli Oilfield Linpan bottom water reservoir for horizontal well development technical problems exist, horizontal well completion technology at home and abroad, an oil sand process conducted an investigation. The level of the bottom water reservoir ridge into the bottom water dynamics, see the water way and flooded law, the numerical simulation and physical simulation experiments, to establish a point-like break and line break, see see the water level of the water wells, see water way. Establish a reservoir and horizontal well bore in the seepage flow coupling mathematical model and solution method to analyze the level of pressure drop in horizontal wells yield on the proposed screen completion better than perforated completion. Screen hole by comparing the density and finite element analysis software ansys at this stage to determine the sieve hole density limit, the actual production situation with oil, the pore density of the variable to improve the production profile screen completion, delaying the water bottom water coning horizontal well completion technology, and through field application of the good results achieved. Sand control completion of horizontal wells combined with the need for precision on the file sand was studied to determine the proposed sand pipe sand filter or sand Sand Screen reasonable accuracy the main component file analysis, to determine a reasonable block sand accuracy.Study in this paper can effectively solve the practical production problems, and has important significance to instruct production development through integrating the research process and practical oilfield production closely.
