METHOD OF GAS RECOVERY FROM WATER-BEARING BED |
摘要 |
FIELD: gas and oil production industry. SUBSTANCE: method is used in development of oil and gas deposits and also in recovery of mineral water from water-bearing beds and sea bottom for technical and medical purposes. According to method, gas and degassed water are taken through string of pump-compressor pipes with lifting of bed water up to well head by means of immersed pump. Lowered into well is second internal string of pump-compressor pipes. Secured in its lower part from external side coaxially is additional pump-compressor pipe with blind bottom at distance of 0.2-0.3 m from shoe of internal string. Degassed water is recovered continuously through internal string of pump-compressor pipes. Gas is taken through annular space between external and internal strings of pump-compressor pipes. Brine water is delivered into annular space between coaxially secured additional pump-compressor pipe and internal string of pump-compressor pipe at speed less than speed of emersion of gas bubbles. Application of aforesaid method ensures increased recovery of gas from well. EFFECT: higher efficiency. 1 dwg
