CONTINUATION OF CONNECTIONS BY OIL PIPELINES WITH RESTORATION OF WELLHEAD PRESSURE OF OIL EXTRACTION OF PRODUCTION WELLS FROM OIL AND GAS OFFSHORE FIELDS

Abstract

In article briefly analizes connections to in-field oil pipelines by restoring the wellhead pressure of offshore oil and gas fields. In the Introduction section, it is stated that the processing of survey data to reduce oil losses during surveys in gas lift wells may produce a result enabling to group these gas lift wells and to apply the results of periodic surveys of one well in a particular group of wells to other wells in the same group with some error. If the in-well equipment of wells operated from same horizons is similar and gas is supplied from the same depth, then the optimal modes of these wells will be close to each other. This was confirmed by the results of laboratory tests. In order to accurately determine the values of parameters to be measured during a field study, it is necessary to reduce the variation interval of the working agent consumption. The design of the gaslift well should ensure there are two channels in the well. Canal for high-pressure gas to be given to well and channel to lift gas- liquid mixture to the surface of the earth. Number of pipes injected into the well, their interaction, there is an oil system of lifts depending on the direction of gas supply and gas-liquid resistance, one and two pipes, depending on the number of pipes injected into the well, there are rings and central system lifts depending on the direction of the worker agent hitting the well. Key conditions for the efficient use of gas lift yield opportunities, is a proper definition of the construction of the lift and its working regime. Additional energy is provided from the surface of the earth to lift liquid in the exploitation of wells by gaslift. You have to work on choosing the gaslift lift's business regime, as well as minimum additional energy, to allow maximum or permitted liquid lifting for a specific well. There are 2 types of gas lift. Energy consumption should be lowest when extracting liquid from well, to ensure optimal harvesting from the well. We need to look at these to extract a certain amount of liquid in the well; the length of the lift and the depth of the lift pipes should be determined, the most cost-effective diameter of lifting pipes, the most cost-effective amount of the worker agent hit should be found, identifying pressure, and the most convenient ratio between the worker agent and the extracted liquid.
