Environmentally friendly technology for monitoring the structure and composition of gas-liquid flows

Purpose. To optimize the operation of the pipeline system, select an effective technology for further processing of the transport mixture, and more accurately predict the residual life of pipeline systems.

Specifications. The technology provides results for monitoring the structure and composition of gas-liquid flows at the level of the following characteristics:  gas phase flow, thousand nm3/day from 5 to 50  oil flow, t/day from 0.2 to 10  water flow, m3/day 1 ,5 to 15 Nominal values of the main relative (reduced to the measurement range) measurement error and maximum deviations from the nominal value: – basic relative (reduced to the measurement range) gas flow measurement error, % ± 5% – basic relative (reduced to the range) measurement) error in measuring oil flow rate, % ± 7% – basic relative (normalized to the measurement range) error in measuring water flow rate, % ± 8%

Application area. Enterprises of the oil and gas sector, chemical-technological production, utility companies of Ukraine

Advantages. The technology created as a result of research to control the structure and composition of gas-liquid flows will be environmentally safe, in contrast to hydraulic fracturing technologies, since the increase in formation fracturing will be carried out using working fluids without the addition of environmentally harmful chemicals. In addition, the technology provides ongoing separation-free monitoring of the structure of multiphase flow of wells and determines the flow rate of gas and liquid phases of the flow in real time.

Technical and economic effect. The cost of processing one well with the developed technology will be 2-4 times less than the cost of work during hydraulic fracturing. Payback period – 2 years. The expected economic effect from using a device for creating sign loads on formations and an IVS for measuring the volume and structure of a hydrocarbon mixture will be at least 2.5 million UAH. per year for one set of devices.

Description. The technology is based on well stimulation through dynamic impact on formations using a developed hydraulic shock device, followed by monitoring the structure and composition of the gas-liquid hydrocarbon flow of the developed IVS and making a decision on the subsequent use of the flow. Component technologies are technological regulations for carrying out work on decolmatation of the bottom-hole formation zone using a pulse-wave hydraulic shock device and monitoring the structure and composition of gas-liquid flows. The technology provides for separation-free control of the structure and composition of gas-liquid mixtures using the latest experimental IVS model with original software.
