Description
Technical field
The utility model relates to oil gas field production gas technology field, and particularly natural gas well intermittent gaslift discharge opeing construction is a kind of isolated plant that utilizes compressed natural gas gaslift draining, is primarily aimed at the gas field watered-out well and recovers gas production production.
Background technology
Along with continually developing of gas field, gas well deliverability reduces gradually, product aqueous vapor well is taken liquid production capacity and is constantly weakened, gas well is taken liquid production difficulty day by day by self-energy, pressure reduction increased between the gas well oil jacket was pressed, gas production continues to successively decrease, and stops production until water logging, cause when driving a well rate low, influence the gas field recovery percent of reserves.For a long time hydrops soaks and tends to gas-bearing formation is caused great pollution and injury, and therefore, discharge opeing fast and effeciently recovers gas production production, is to keep gas well deliverability, efficiently develop the key in gas field.
At present, well head stationary compressors are adopted in some gas fields, carry out the intermittent gaslift discharge opeing to opening producing well, and a compressor only can carry out the supercharging discharge opeing to a bite gas well, exists problems such as investment is big, management maintenance cost height, and utilization rate of equipment and installations is low.
The utility model content
The purpose of this utility model is: a kind of vehicle-mounted natural gas compressor gaslift pumping equipment is provided, by natural gas compressor the well head natural gas is injected pit shaft from sleeve pipe, utilize injection high pressure gas and stratum output natural gas to take liquid jointly, ability reaches discharges the shaft bottom hydrops, makes the water logging natural gas well recover gas production production.
The technical solution adopted in the utility model is: vehicle-mounted natural gas compressor gaslift pumping equipment, mainly form by vehicle-mounted natural gas compressor, wellhead assembly, gas-liquid separator, sewage jar, block valve, flow meter and stabilizator, on wellhead assembly, have, the first well head sleeve valve, the second well head sleeve valve and well head are produced valve, it is characterized in that: the first well head sleeve valve connects the exhaust opening of vehicle-mounted natural gas compressor by high-pressure hose, can inject high-pressure natural gas after compressing toward the oil jacket annular space; Produce on the valve at the second well head sleeve valve of wellhead assembly and well head and to be connected with pipeline respectively, and two pipelines are parallel on the extraction pipeline, the other end of extraction pipeline connects the import of gas-liquid separator; Water out at gas-liquid separator has pipeline to connect the sewage jar, and the sewage of separating can flow into the sewage tank stores.At the gas outlet of gas-liquid separator by a pipeline block valve of series connection and a flow meter; The outlet of flow meter is connected with the gas gathering station connecting line; Connect a source gas line by threeway on the gas gathering station connecting line, the other end of source gas line connects the air inlet port of vehicle-mounted natural gas compressor; On source gas line, be connected with a stabilizator.
On the extraction pipeline, be connected with a needle-valve.
Described source gas line is a flexible rubber hose.
Sketch the course of work of vehicle-mounted natural gas compressor gaslift pumping equipment.The natural gas that utilizes gas gathering station and eliminator to separate, source of the gas as vehicle-mounted natural gas compressor, natural gas is through injecting gas well oil jacket annular space after the supercharging, hydrops in the pit shaft is enumerated from oil pipe, by well head production noticeable degree gas well open flow pressure and tolerance, come gas to mix as source of the gas gas with flow line after the natural gas via gas-liquid separation of enumerating from oil pipe, fluid separation applications is after blowoff valve enters the sewage jar.
The beneficial effects of the utility model: the vehicle-mounted natural gas compressor gaslift of the utility model pumping equipment, on probation by the scene, do not establish in the down-hole under the situation of gas lift valve and formation water can be discharged from pit shaft, realized circulation gaslift water pumping gas production, be provided with the sewage jar, not emptying of well head, not blowdown of scene, safety and environmental protection, adopt vehicle-mounted natural gas compressor to have and move flexibly, advantages such as operation is convenient, one chassis carries natural gas compressor can implement gaslift recovery gas production production to many mouthfuls of watered-out wells, has improved utilization rate of equipment and installations greatly.
