Description
Technical field
The utility model relates to oil gas field production gas technology field, and particularly many implications of gas field cluster well group well can continue simultaneously, stablize and carry out the device that gas production is produced.
Background technology
At present, the gas production of cluster well group is taked in some gas fields, enters the station, measures, separates, fails outward after promptly the next natural gas via main line manifold of many implications well well head closes.Owing in the natural gas well in the cluster well group, the gas well that is higher than system pressure is arranged, needs to throw in underground throttle device, controlled pressure; Also have the stratum energy deficiency, pressure is lower than the low-pressure gas well of system pressure, can't ordinary production.The recovery percent of each gas well and reservoir properties difference, the pressure of each gas well, tolerance there are differences in the well group, cause after same main line manifold closes phase mutual interference between each well.For avoiding phase mutual interference between well, can only take intermittently, production model is exploited by turns.Rate when influence drives a well has like this limited the performance of each gas well deliverability of cluster well group.In addition, exist in the cluster well group and drive gas well between low pressure, pressure descends rapidly during production, is difficult to continuous, steady production, and exploitation is difficulty comparatively.
The utility model content
The purpose of this utility model is: a kind of injection drainage system that is used for the cluster well group is provided, utilize other gas well of a bite high-pressure gas well injection in the cluster well group, make each gas well of cluster well group can be continuously, steady production, rate when improving the gas well gas production is to reach the purpose of the reasonable high-efficiency mining of cluster well group gas well.
The technical solution adopted in the utility model is: the injection drainage system that is used for the cluster well group, mainly form by high-pressure gas well, low-pressure gas well, gas ejector, slide valve and pipeline, in the natural gas well group, the outlet of the head valve group of each natural gas well is connected with pipeline.It is characterized in that: the outlet line of the head valve group of a bite high-pressure gas well connects the import of gas ejector, has pipeline to connect gas external transport pipeline in the outlet of gas ejector, on the suction line of gas ejector and outlet line slide valve is arranged.On the intake of gas ejector, there is pipeline to connect the outlet of the head valve group of low-pressure gas well.On the pipeline that exports to the gas ejector intake of the head valve group of low-pressure gas well, slide valve is arranged.High pressure, high gas rate well offer the continuous production of low-pressure gas well institute energy requirement.
If in a plurality of low-pressure gas wells, there is the pressure of other gas well to be higher than system pressure, can in pressure is higher than the gas well of system pressure, underground throttle device be installed, on the pipeline that exports to the gas ejector intake of the head valve group of the gas well that is higher than system pressure, slide valve be arranged.Other gas pressure that is higher than the gas well extraction of system pressure is reduced, can cooperate with other low-pressure gas wells.Make by drainage gas well pressure and all be lower than system pressure.
Convenient, easy to maintenance for gas production, the outlet line of the head valve group of high-pressure gas well connects gas external transport pipeline; The outlet line of the head valve group of low-pressure gas well connects gas external transport pipeline; The outlet line of head valve group that is higher than the gas well of system pressure connects gas external transport pipeline.
What underground throttle device adopted is the adjustable gas testing body of EJT ejector.There is sale in market.
The beneficial effects of the utility model: the utility model is used for the injection drainage system of cluster well group, has the following advantages:
1, cluster well group, high pressure, low-pressure gas well can be produced simultaneously.After the cluster well group use to be sprayed drainage system, gas well can drive a well simultaneously, and natural gas enters main after mixing, rate when having improved the driving a well of cluster well group gas well, and gas well is realized efficient exploitation.
2, utilize in the high-pressure gas well injection cluster well group between drive gas well, make gas well can be under lower pressure continuously, steady production, the rate during gas production of driving gas well between raising.
3, improve the pipeline operating safety factor.It is 5.2MPa that natural gas mixes back pressure, and the pipeline operating pressure reduces greatly, has improved the safety factor of pipeline operation.
4, reduce the methyl alcohol injection rate.When gas well is produced, stop up, need to inject methyl alcohol for preventing hydrate, use this device after, pressure reduces, and has reduced the hydrate formation condition, minimizing hydrate blocking pipeline is guaranteed the gas well continuous and stable production.
