Description

A kind of circulating gas-liquid mixes defeated pressurizer and method
Technical field
The present invention relates to a kind of gas-liquid delivery pressurizer and method, belong to gas-liquid delivery supercharging technology field, specifically relate to And a kind of circulating gas-liquid mixes defeated pressurizer and method.
Background technology
With the development in desert, the exploitation in marine oil gas field and oil-gas gathering and transportation supporting technology, oil gas water multi-phase mixed delivering skill Art has obtained increasingly being widely applied.It is current oil by multi-product pipeline after the low pressure oil gas medium supercharging that well head is produced Gas distance, the most effective approach of high efficiency transport, have great Social benefit and economic benefit.
Traditional well site mixed transportation process is as follows: first low pressure mixed with defeated medium and heats, then carry out gas-liquid separation again, The liquid medium isolated is stored in fluid reservoir, enters mixed transporting tube net after output pump extracts supercharging;The gas isolated Medium is pressurized by compressor after filtering again, and the high-pressure gas medium after supercharging enters gas line network, realizes gas-liquid Mixed defeated.Wellsite facility is mainly made up of mechanical commprssor, heating furnace, separator, filter, fluid reservoir, output pump etc., equipment More, complex process, fault is more, and is difficult into sled it is impossible to centralized Control, in-site installation trouble, and installation period is long, takes up an area face Long-pending big, be not suitable for transition transport.In addition, mechanical compressor is very narrow to the area requirement of admission pressure, and mix defeated pressure medium model Enclose too wide, pressure need to be depressured in the range of compressor permission, then be pressurized, energy loss is serious;Saturation water (liquid in gas Body) compressor risen with destruction, compressor fault rate is high.
Also have a kind of well site mixed transportation process at present: first low pressure is mixed with defeated medium and carry out gas-liquid separation, the liquid isolated In fluid reservoir, the gas medium isolated is pressurized after filtering media storage again by compressor, the height after supercharging Pressure gas medium enters fluid reservoir again, liquid medium is released and enters mixed transporting tube net, realize gas-liquid delivery.Wellsite facility is mainly Hydraulic compressor, separator, filter, fluid reservoir etc. form, and wellsite facility is less, and technique is simpler.Mixed defeated pressure medium is high When, using hydraulic compressed machine, there is discharge capacity greatly, energy consumption is low, the low advantage of fault rate;But when well head, to mix defeated pressure medium relatively low When, hydraulic compressor discharge capacity very low it is impossible to meet field working conditions demand, such as need to meet discharge capacity demand, then need increase equipment chi Very little, improve plant capacity, equipment energy consumption is big, and manufacturing cost is very high, and Project in Operation benefit is low.Also has the height it is simply that after compression When body of calming the anger pushes away the liquid in fluid reservoir, the separator of front end also in work, cannot discharge, if liquid by the big quantity of fluid that it produces Amount is larger, then liquid easily diffuses out separator, enters in compressor, compressor is damaged.
For this reason, the designer of the present invention is in view of drawbacks described above, by concentrating on studies and designing, comprehensively it is engaged in for many years for a long time The experience of related industry and achievement, research design goes out a kind of circulating gas-liquid and mixes defeated pressurizer and method, to overcome above-mentioned lacking Fall into.
