The invention relates to the technical field of carbonate reservoir ground produced liquid gathering, transportation and water injection, in particular to a carbonate reservoir multi-well oil gathering and water distributing device and a using method. The carbonate reservoir multi-well oil gathering and water distributing device comprises a water supply main pipe, an oil gathering main pipe, a metering liquid conveying pipe and at least one oil gathering and water distributing pipe, wherein distributing pipes with the same number as the oil gathering and water distributing pipes communicate between the metering liquid conveying pipe and the oil gathering main pipe. According to the carbonate reservoir multi-well oil gathering and water distributing device and the using method, according tothe law of alternate operation of oil extraction and water injection of a carbonate reservoir, meanwhile, it is considered that wells do not influence one another, the requirements of oil gathering,water supply and distribution and well selection metering are met, and by utilizing intermittent asynchronism of oil extraction and water injection, oil is gathered while oil extraction and water is distributed while water injection; and the device meets the requirements of simultaneous oil gathering and water distributing of the plurality of wells, oil gathering and water distribution among the wells do not affect one another, and oil gathering and water distribution of a single well operate alternately, so that oil gathering and water distribution are integrated by the device, the use load rate of the device is increased, and gathering and transportation pipelines are fully utilized.
Description
technical field [0001] The invention relates to the technical field of surface production liquid gathering, transportation and water injection in carbonate oil reservoirs, and relates to a multi-well oil collecting and water distribution device in carbonate oil reservoirs and a use method thereof. Background technique [0002] At present, in the surface engineering of carbonate oilfields, the oil and gas gathering and transportation process is a conventional oilfield technology; the intermittent and uncertain water injection forms an injection process of low-pressure water supply and well site pressurization; separate pipes are mostly used for gathering, transportation and water distribution. Network, and build oil collection valve group equipment and water distribution valve group equipment at relatively concentrated points. [0003] Carbonate oilfields have the characteristics of multi-stage karstification, multi-stage accumulation, high heterogeneity, and complex bottom w...
