| description | FIELD: oil and gas industry.SUBSTANCE: development method of a deposit of high-viscosity and heavy crude oil involves drilling of one vertical production well. An inspection well is drilled at the distance of 30 m from it; a seismic pickup connected at the head to digital recording equipment is lowered into the inspection well; recording of seismic vibrations in the production well is performed. Hydraulic fracturing is performed in the production well. As per processing results of seismic signals, direction of crack propagation and its dimensions as per azimuth is performed. On both sides from the hydraulic fracturing crack formed out of the production well and at the distance of 15 m from the crack axis and parallel to it there drilled is one row of vertical injection wells with distance of 15 m between wells. Pump equipment is lowered to the production well. Electrical heating equipment is lowered by means of a cable to each injection well. Simultaneous heating of the formation is performed through injection wells and selection of the heated oil is performed from the production well till complete mining-out. Then, the production well is changed over to the inspection one. The second production well is drilled parallel to the shaft of the inspection well changed over from the production well at the distance of 30 m. Then, the above described process is repeated starting from lowering of the seismic pickup to the inspection well. At deviation of the axis of the crack formed out of the second production well from parallel direction to the axis of the crack formed out of the first production well to an angle of 15° and less for mining-out of a bottomhole area of the second production well, there used is an existing row of injection wells; an additional row is drilled parallel to the axis of the crack formed out of the second production well. At deviation of the axis of the crack formed out of the second production well from parallel direction to the axis of the crack formed out of the first production well to an angle of 15° and more for generation of the bottomhole area of the second production well there drilled is a new row of injection wells parallel to the axis of the crack formed out of the second production well at the distance of 15 m from it, and wells of the existing row of injection wells located at the distance of more than 20 m and less than 10 m from the axis of the crack formed out of the second production well are liquidated.EFFECT: improving |

Изобретение относится к разработке нефтяных месторождений. Технический результат - повышение эффективности разработки залежи. В способе разработки залежи высоковязкой и тяжелой нефти сначала бурят одну вертикальную добывающую скважину. На расстоянии 30 м от нее бурят наблюдательную скважину, спускают в наблюдательную скважину сейсмоприемник, обвязанный на устье с цифровой регистрирующей аппаратурой, осуществляют регистрацию сейсмических колебаний в добывающей скважине. Производят гидроразрыв пласта в добывающей скважине. По результатам обработки сейсмических сигналов определяют направление развития трещины и ее размеры по азимуту. С двух сторон от трещины гидроразрыва, образованной из добывающей скважины, и на расстоянии 15 м от оси трещины и параллельно ей бурят по одному ряду вертикальных нагнетательных скважин с расстоянием 15 м между скважинами. В добывающую скважину спускают насосное оборудование. В каждую нагнетательную скважину спускают электронагревательное оборудование на кабеле. Осуществляют одновременное прогревание пласта через нагнетательные скважины и отбор разогретой нефти из добывающей скважины до полной выработки. Затем добывающую скважину переводят в наблюдательную. Параллельно стволу наблюдательной скважины, переведенной из добывающей скважины, на расстоянии 30 м бурят вторую добывающую скважину. Затем процесс, описанный выше, повторяют, начиная со спуска в наблюдательную скважину сейсмоприемника.
