Description

Известные способы исследовани  скважин на приток или на приемистость требуют в первом случае откачки жидкости из скважины, а во втором - подлива жидкости в скважину. Дл  осуществлени  этих способов исследовани  требуетс  соответствующее оборудование скважннн , наличие емкостей и жидкости, что делает эти способы громоздкими и трудоемкими.Known methods of well testing for inflow or injectivity require, in the first case, pumping fluid from the well, and in the second, pouring fluid into the well. To carry out these exploration methods, appropriate borehole equipment is required, as well as the presence of tanks and liquids, which makes these methods cumbersome and time consuming.

Дл  повышени  качества исследовани и сокращени  времени их при применении описываемого способа понижение уровн  в скважине осуществл етс  нагнетанием в нее газа под давлением с одновременным прослеживанием понил ающегос  уровн  при установившемс  давлении или сн тием давлени  путем выпуска из скважины сжатого воздуха и прослеживанием повышающегос  уровн .To improve the quality of research and reduce their time when applying the described method, lowering the level in a well is carried out by injecting gas under pressure while simultaneously tracking an understanding level with steady pressure or relieving pressure by releasing compressed air from the well and tracking an increasing level.

На чертеже показана принципиальна  схема оборудовани  скважины дл  осуществлени  предлагаемого способа.The drawing shows a schematic diagram of the equipment of a well for carrying out the proposed method.

В скважине / устанавливают пьезограф 2, фиксирующий изменение уровн  с по.мощыо поплавка 3, соединенного с пьезографом проволокой 4. Устье скважины герметично закрывают крышкой 5, снабженной образцовым манометром 6 дл  наблюдени  за давлением в скважине. Газ (азот, воздух и др.) под давлением доставл ют в баллоне, 7, который соедин ют со скважиной через регул тор 8, поддерживающий дав , ление в скважине на заданной величине.A piezograph 2 is installed in the well / fixing the level change from the float 3 connected to the piezograph by wire 4. The wellhead is sealed with a cover 5 fitted with an exemplary manometer 6 to monitor the pressure in the well. Gas (nitrogen, air, etc.) under pressure is delivered in a cylinder 7, which is connected to the well through regulator 8, which maintains the pressure in the well at a predetermined value.

Положение уровн  следует фиксировать только после того, как установитс  давление. Прослежива  положение уровн  во времени при посто нном давлении в скважине опреде.т ют ее приемистость.The position of the level should be fixed only after the pressure has been established. Tracing the position of the level in time at a constant pressure in the well determines its injectivity.

Дл  определени  притока жидкости из пласта в скважине понижают уровень, создава  давление над ним описанным способом. Затем быстро выпускают воздух из скважины и прослеживают положение уровн  во времени.To determine the flow of fluid from the formation downhole, the level is reduced, creating pressure over it in the manner described. Then, air is quickly released from the well and the level is traced over time.
