Along with gas field development time duration, part gas well stratum energy declines gradually, gas well fluid-carrying capability weakens, pit shaft hydrops phenomenon increases gradually, if pit shaft hydrops can not be discharged in time, can cause pit shaft pressure drop to raise, increase the back pressure of liquid to gas-bearing formation, cause gas production sharply to decline, even occur the phenomenon of dried-up well.Current Domestic Gas Industry in metering filing provision field is all substantially, low pressure is main, pressure, between 5～50MPa, cannot guarantee that high pressure measurement injects the use of new technology.In tight gas and shale gas exploitation, along with the introduction of external new technology, existing equipment cannot meet project implementation.
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition is that prior art is improved, a kind of high pressure chemistry agent filling skid mounted equipment is provided, solve filing provision in current technology and cannot guarantee that high pressure measurement injects the use of new technology, the problem that gas well output sharply declines with exploitation.
For solving above technical problem, the technical solution of the utility model is:
A kind of high pressure chemistry agent filling skid mounted equipment, comprise skid, it is characterized in that, the integrated parts such as diaphragm metering pump, storage tank, high pressure sluice valve, y-type filter, pressure duct and ball valve in described skid, design pressure is 85MPa, flow is 230L/h, storage tank is connected to diaphragm metering pump by high pressure sluice valve and y-type filter, chemical agent enters pressure duct after by diaphragm metering pump supercharging, be input to ball valve via pressure duct, outputed in the connecting line of gas well by ball valve control high pressure chemistry medicament.The utility model is selected the power conveying device of diaphragm metering pump as system, and design pressure is 85MPa, and flow is 230L/h, realizes high-pressure well mouth filling.Be stored in storage tank using the chemical agent such as methyl alcohol, corrosion inhibiter as working media, carry out high pressure filling to natural gas well head and pipeline.The natural gas of the high pressure under gas well will utilize just needs to adopt throttling expansion refrigerating method to remove water and the heavy hydrocarbon in natural gas, for unlikely generation hydrate in throttling expansion process of refrigerastion, before throttling, inject methyl alcohol and avoid generating hydrate, cause ice stifled, impact is produced, and particularly gas well needs to inject continuously before driving a well.Utilize high pressure chemistry agent filling to guarantee the continuity exploitation of gas well.
Further, on described diaphragm metering pump, be connected with high-tension damper, guarantee the stable of injection pressure, and preliminary filling air pressure is controlled to 70% well head pressure or the highest 25MPa, and provide inflatable tool and nitrogen to increase unit.
Further, in described pressure duct, dispose safety valve, needle-valve, flap valve and drain valve protection system safety, and there is backflow, emptying function, in case of emergency can turn-off fast.
Further, pipe fitting in described pressure duct connects the high pressure cutting ferrule adopting more than product work pressure 103MPa and connects, and avoids adopting the mode of welding and occurs problems of welded quality.
Further, on described storage tank, being provided with breather valve, spark arrester and magnetic flap level gauge assurance system normally uses safely.
Further, described storage tank is provided with Calibration Column, and to diaphragm metering pump, output is checked and calibrated, and guarantees to produce and the requirement that drives a well.
Compared with prior art, the utility model advantage is:
High pressure chemistry agent filling skid mounted equipment described in the utility model has solved the super-pressure loading technique of well head chemical agent, realize pressure 85MPa, the well head filling of flow 200L/h, optimize technological process, the stability of a system is good, guarantee the continuity exploitation of natural gas, solved current gas well output and sharply declined and even occur the problem of dried-up well phenomenon with exploitation; The utility model is simple in structure, is easy to realize, and low cost of manufacture, business efficiency is high, can effectively enhance productivity.
