METHOD OF DEVELOPING AN OIL FIELD WITH A FRACTURED RESERVOIR Russian patent published in 2018 - IPC E21B43/20 E21B43/17 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to petroleum industry and can find application in development of an oil reservoir with a fractured reservoir. By the method a pilot well is drilled. According to the data of geophysical studies in the productive reservoir of the prevailing direction of fracture of the field. From the pilot bore hole the same multidirectional paired horizontal trunks, which are directed to opposite sides from the well, are drilled. First pair of horizontal trunks are drilled perpendicular to the direction of natural fracturing. In this case after posting of each horizontal barrel by selection, the increase in production rate in the pilot vertical well is determined. After completion of construction of horizontal trunks, the increment of the rates of paired trunks is summarized. Select the two most productive pairs of trunks. When viewed from above in the direction of the pairs, vectors are created starting in the pilot vertical borehole, proportional to the total production rate of these pairs with an angle between them not exceeding 90°. Summarize the resulting vectors. In parallel to the direction of the resulting vector, the entire reservoir is equipped with horizontal production wells and injection wells. Pumping of working agent is done through injection wells and recovery of products through multi-hole production wells.

EFFECT: increase efficiency of development by taking into account direction of the actual migration of products in the formation, as well as simplifying development and its cheaper.
