Claims (4)

1. Способ разработки нефтяного многопластового месторождения на поздней стадии разработки, включающий бурение нагнетательных и добывающих скважин, закачку вытесняющей жидкости в нагнетательную и отбор продукции пласта через добывающую скважину, отличающийся тем, что после вскрытия бурением первого верхнего пласта продуктивного пласта До, в разрезе кыновских глин, подверженных осыпаниям и разбуханию, геофизическими исследованиями устанавливают его рентабельность разработки, после чего пробуренную часть скважины крепят, затем бурение продолжают долотом меньшего диаметра и вскрывают следующий продуктивный пласт Д буровым раствором на равновесии или депрессии с целью сохранения коллекторских свойств пласта, и если он рентабелен, то его разрабатывают открытым забоем до полной выработки и далее по аналогичной схеме бурением вскрывают и разрабатывают последовательно остальные нижележащие пласты - пачки Д, после выработки этих пластов бурением вскрывают высокопроницаемые обводненные пласты Д, Д Д и скважину обсаживают хвостовиком, крепят, после чего их по отдельности разрабатывают.1. A method of developing an oil multilayer field at a late stage of development, including drilling injection and producing wells, injecting displacing fluid into the injection and selecting production of the formation through the producing well, characterized in that after drilling the first upper formation of the reservoir, D o , in the context of the Kynovsky clay, prone to shedding and swelling, geophysical studies establish its profitability of development, after which the drilled part of the well is fixed, then drilled they continue with a bit with a smaller diameter and open the next productive formation D 1a with drilling fluid at equilibrium or depression in order to preserve the reservoir properties of the formation, and if it is cost-effective, it is developed by open-hole mining until it is fully developed and then, using a similar scheme, open and develop the remaining underlying ones strata - packs D 1b , after the development of these strata by drilling, open high-permeable flooded formations D 1v , D 1g D 1d and the well is cased with a shank, fixed, after which they are individually develop. 2. Способ по п.1, отличающийся тем, что если вскрытый продуктивный пласт склонен к осыпанию, то его перекрывают легкоразбуриваемым хвостовиком, например, из стеклопластикового или алюминиевого материала.2. The method according to claim 1, characterized in that if the opened reservoir is prone to shedding, then it is covered with an easily drilled shank, for example, of fiberglass or aluminum material. 3. Способ по п.1, отличающийся тем, что если два близлежащих продуктивных пласта Д и Д однородны по проницаемости и сложены крепкими породами, то их разрабатывают совместно открытым забоем.3. The method according to claim 1, characterized in that if two nearby productive formations D 1a and D 1b are homogeneous in permeability and are composed of strong rocks, then they are developed jointly by open face. 4. Способ по п.1, отличающийся тем, что необходимость прекращения бурения или дальнейшего углубления определяют геофизическими исследованиями, например, газовым каратажом и анализом шлама.4. The method according to claim 1, characterized in that the need to stop drilling or further deepening is determined by geophysical surveys, for example, gas casing and sludge analysis.
