METHOD DEVELOPMENT multilayer OIL FIELDS

摘要

1. A method for developing multilayer oilfield, the method comprising: performing drilling in accordance with the depths of the existing draft oilfield development neftenosnosti clarify the contours, if refinement results indicate the presence of extra oil in the lower layers, then decide whether to develop these stocks, with a positive result of the decision to said drilling deepens the underlying layers of the rock faces of previously drilled wells, which are located in the section at the point ah intersection with layers containing additional oil reserves, iproizvodyat production of all be developed oily plastov.2. A method according to claim 1, wherein the extraction of oil-producing formations individually in depth order of their occurrence starting from naibolshey.3. A method according to claim 1, wherein the extraction of oil-producing formations simultaneously using a device for dual utilised.4. A method according to claim 1, wherein the presence of said additional oil reserves make a decision based on the evaluation of developing these zapasov.5 profitability. A method according to claim 1, wherein the presence of said additional oil reserves decide on the basis of evaluation of the properties of layers containing these stocks, and the potential implications of the development of these stocks to develop overlying zapasov.6. A method according to claim 1, wherein the presence of said additional oil reserves make a decision based on the fact of detection of the underlying non-drainable oil-saturated zones.
