Technical field
The present invention relates to a kind of Large Diameter Pipeline gas well well flow rate controller and processes, belong to oil gas field production gas technology
Field.
Background technology
In recent years, with the continuous development of exploration and development technology, the exploitation of unconventional petroleum resources is increasingly taken seriously.
Volume fracturing is used as to one of the important means of unconventional reservoir transformation, is also attracted attention more and more.Volume fracturing refers to
In hydraulic fracturing process using 4.5in pressure break gas production integrated pipe columns using huge discharge, large sand amount, big liquid measure, low sand than
Injection mode make intrinsic fracture constantly expand and brittle rock generate shearing slip, formed intrinsic fracture mutually handed over man-made fracture
Wrong fracture network improves initil output and ultimate recovery to increase transformation volume.
Downhole flow control technology is to install the oil nozzle of certain mouth diameter in underground and prevent hydrate using ground temperature heating to generate
To realize a kind of technology of gas well flow control.Gas well flow in order to control, currently, Soviet Union's Sulige gas field 4.5in tubing string volume fracturings
Well is using the generation of hole top heating furnace heating prevention hydrate, the operation pattern of metering pin valve aperture.There is heating in this mode of production
Stove need to consume natural gas, be unfavorable for energy-saving and emission-reduction, surface technology complexity, costly disadvantage.Using such operation pattern be because
Big for 4.5in tubing string calibers, pressure-bearing is big, and the control of gas well flow is realized there has been no well flow rate controller.
