Abstract

The invention relates to a high-efficiency energy-saving oil exploitation method. The process for realizing the method is as follows: a multi-phase flowmeter is provided, can adapt to more oil well environments and meters the yields of oil, gas and water produced by oil wells independently at real time in the sites of production wells; and meanwhile, heating equipment of well mouths is installed at the required well mouths, the heating power is controlled by utilizing the metering data of the oil wells and parameters set manually according to the requirements of gathering and transferring, and the condition of heating as required is realized. A metering station is cancelled, the production wells are locally connected together by using pipelines, mixed fluid produced by the oil wells enters a multi-purpose station directly and is dewatered and degassed, and then the qualified crude oil is output outwards. Data processing equipment (or named as other names) of the well mouths integrally collects and processes various data of the well mouths simultaneously, automatic oil extraction, automatic metering, automatic heating, gathering and transferring and automatic accident judgment and treatment are directly realized at the well mouths, the entire oil extraction system is divided into areas according to the requirement, the data processing equipment of the oil wells is connected into a network according to the areas, and integral control is realized.

Description

Technical field: [0001] The invention belongs to the technical field of petroleum exploitation, and in particular relates to a technology integrating the monitoring of oil production wells with the measurement and delivery technology after the oil production wellhead. Background technique: [0002] The existing oil production method is to use oil production equipment to lift the multi-media fluid mixture of oil, gas and water from the formation to the ground. The content of this multi-phase mixture medium varies greatly and also contains impurities such as sediment. Due to the lack of suitable multiple flow meters, the metering work cannot be completed at the head of the oil production well, and the mixture can only be transported to the metering station through the pipeline. Time is measured, and the results are converted into full-day production. The measured mixture is then transported to the joint station. After degassing and dehydration at the joint station, qualified c...
