Method of determining volume and interval of deposits in pipeline

FIELD: oil, gas and coke-chemical industries. SUBSTANCE: invention relates to oil industry and can be used in detection of scaling in an oil-field pipeline. Method of determining volume and interval of deposits in a pipeline comprises arranging movement of liquid through a pipeline with constant and known flow rate, simultaneously with selected points regularly spaced along length of pipeline, flow rate of this liquid is determined through a pipeline, pressure is changed with determination of sections with maximum volume of deposits in the pipeline. In sections with minimum pressure, radiographic inspection is performed by means of X-ray imaging to a section of pipeline free from salt deposits. Radiographic control is followed by dosimetric monitoring at the same site. EFFECT: disclosed method of determining volume and interval of deposits in a pipeline enables to determine accurate location of intervals and value of deposits by duplicating measurements using X-ray and dosimetry control with minimum costs, absence of complex calculations and visual confirmation of deposits on internal walls of oil pipeline. 1 cl РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 733 558 C2 (51) МПК F17D 3/00 (2006.01) G01N 23/00 (2006.01) E21B 47/003 (2012.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК F17D 3/00 (2020.01); G01N 23/00 (2020.01); E21B 47/0003 (2020.01) (21)(22) Заявка: 2018138322, 31.10.2018 (24) Дата начала отсчета срока действия патента: Дата регистрации: (73) Патентообладатель(и): Публичное акционерное общество "Татнефть" имени В.Д.

Pipeline optimizer system

본 발명의 일 실시예는 유전적 알고리즘을 사용함으로써 파이프라인 동작의 다양한 양상을 최적화하는 방법을 제공한다. 일반적으로, 유전적 알고리즘은 종료 조건이 충족될 때까지 연속적인 생성을 통하여 실행 가능한 솔루션들의 모집단을 진화하기 위해 사용된다. 각각의 솔루션은 파이프라인 시스템의 실행 가능한 동작 상태를 지정한다. 연속적인 생성을 통하여 기존의 솔루션들이 수정되고, 각각의 연속적인 생성에서 모집단의 식별된 솔루션이 제거된다. 반복되는 생성을 통하여, 모집단의 솔루션들은 향상된다. 최적화된 생산 솔루션이 생성되면, 직접 압력 최적화 프로세스를 사용하여 최적화된 압력 솔루션이 생성될 수 있다. One embodiment of the present invention provides a method of optimizing various aspects of pipeline operation by using genetic algorithms. In general, genetic algorithms are used to evolve a population of viable solutions through successive generations until termination conditions are met. Each solution specifies the operational state of the pipeline system. Successive generations modify existing solutions and remove the identified solution of the population in each successive generation. Through repeated generation, the solutions of the population are improved. Once an optimized production solution is created, an optimized pressure solution can be created using a direct pressure optimization process.

Method for automatic load distribution between low-temperature gas separation lines at gas treatment plants using air cooling units, oil and gas condensate fields of northern russia

FIELD: oil, gas and coke-chemical industries.SUBSTANCE: invention relates to the field of extraction and preparation of natural gas for long-distance transportation at complex gas treatment plants (CGTP) of oil and gas condensate fields (OGCF) of Northern Russia. Proposed method includes control of a number of parameters by means of an automated process control system (APCS) of the CGTP. Among them is the flow of dried gas supplied to the main gas pipeline (MGP) and the flow of unstable gas condensate (UGC) supplied to the main condensate line (MCL). APCS maintains temperature of gas separation in each low-temperature separator and controls mode of its operation at specified value of gas flow therefrom. APCS, having received the task on production volume of CGTP UGC, executes it by means of PID-regulator of flow rate maintenance of UGC in MCL, implemented on the basis of APCS. At the SP input, this proportional-integral-derivative controller (PID) controller of the APCS PID controller controls the dispatcher setting signal, and at the same time to its feedback input the PV signals the current flow rate of the UGC to the MCL. Comparing the setpoint and current flow rate of the UGC, this PID controller generates a CV at its output CV, which sends the PID regulators of all process lines (PL) of low-temperature separation (LTS) of the gas, which are also implemented on the basis of APCS. To the PV feedback input of these PID-controllers APCS transmits the signal of actual flow of dried gas to CGTP. Also, at the input of CV of PID-controllers of each LTS TL, a signal of the coefficient of the proportionality factor Cp_i, (where i is the LTS TL number), which determines the degree of action of this PID-controller on the control valve (CV) of the gas flow rate through it LTS TL. Value of the coefficient of proportionality Cp_iis determined for each LTS TL by its proportionality coefficient calculation unit depending on the cooling capacity of its air cooling apparatus (ACA ...
