Abstract
Description
Изобретение относится к ледоведению и ледотехнике и может быть использовано в ледовых исследованиях, в частности, в районах добычи углеводородов на шельфе замерзающих морей.The invention relates to ice research and ice engineering and can be used in ice research, in particular in areas of hydrocarbon production on the shelf of freezing seas.
Стамуха представляет собой неподвижный торос, образовавшийся или придрейфовавший на мелководье и сидящий на грунте. Задачей исследования внутреннего строения льда является оценка возможных воздействий этих ледяных образований на различные морские сооружения.A ham is a stationary hummock, formed or drifted in shallow water and sitting on the ground. The task of studying the internal structure of ice is to assess the possible effects of these ice formations on various offshore structures.
Известные дистанционные методы исследования льда, такие как радиолокация и гидролокация, не могут обеспечить получение достоверных данных о внутреннем строении торосов и стамух из-за помех при зондировании неоднородного льда. Для таких исследований обычно проводят бурение скважин во льду с отбором или без отбора керна.Known remote ice research methods, such as radar and sonar, cannot provide reliable data on the internal structure of hummocks and hammers due to interference when probing heterogeneous ice. For such studies, drilling of wells in ice is usually carried out with or without coring.
Известен способ определения расположения границы льда и грунта при бурении стамух горячей водой [1, 2]. Во время бурения измеряют температуру талой воды вблизи забоя. Граница льда и грунта относительно поверхности льда расположена на глубине, при которой произошло резкое изменение температуры воды на забое и уменьшение скорости бурения до полной остановки термобура. Достоинством данного способа является достоверность определения расположения границы льда и грунта. Недостатком является неоднозначность при бурении стамухи остывшей рабочей водой из-за большого удаления водоподогревателя от объекта исследования или по иным причинам.There is a method of determining the location of the boundary of ice and soil when drilling stamukha hot water [1, 2]. During drilling, melt water temperature is measured near the bottom. The border of ice and soil relative to the ice surface is located at a depth at which a sharp change in the temperature of the water at the bottom and a decrease in the drilling speed until the thermal drill stops completely. The advantage of this method is the reliability of determining the location of the border of ice and soil. The disadvantage is the ambiguity when drilling the granite with cooled working water due to the large distance of the water heater from the object of study or for other reasons.
Целью настоящего изобретения является получение при водяном бурении объективной информации для определения расположения границы льда и грунта.The aim of the present invention is to obtain during water drilling objective information for determining the location of the boundary of ice and soil.
Указанная цель достигается следующими действиями:The specified goal is achieved by the following actions:
1. В процессе теплового бурения-плавления льда производят запись на компьютер скорости бурения и прозрачности талой воды. Как только термобур проходит сквозь лед в грунт, в скважине появляется взвесь воды и грунта или ила, и прозрачность ее резко уменьшится, даже если термобур продолжает погружаться, размывая грунт.1. In the process of thermal drilling-melting ice, the drilling speed and transparency of melt water are recorded on a computer. As soon as the thermal drill passes through the ice into the soil, a suspension of water and soil or silt appears in the well, and its transparency decreases sharply, even if the thermal drill continues to sink, eroding the soil.
2. При последующей обработке этих данных на компьютере сопоставляется зависимость скорости бурения с прозрачностью талой воды. Глубина, на которой произошло уменьшение прозрачности талой воды, соответствующее переходу бура изо льда в грунт, определяется как глубина расположения границы льда и грунта.2. During subsequent processing of these data on a computer, the dependence of the drilling speed on the transparency of melt water is compared. The depth at which there is a decrease in the transparency of melt water, corresponding to the transition of the drill from ice to soil, is defined as the depth of the location of the boundary between ice and soil.
Предлагаемый способ обеспечивает получение большого объема необходимой объективной информации о строении стамух. Экономический эффект от использования предлагаемого способа состоит из экономии времени высококвалифицированных специалистов при полевых работах. Учитывая повышенный интерес к строению торосистых образований в районах добычи углеводородов на шельфах замерзающих морей, настоящее предложение можно считать актуальным.The proposed method provides a large amount of necessary objective information about the structure of the gangs. The economic effect of using the proposed method consists in saving time of highly qualified specialists in the field. Given the increased interest in the structure of hummock formations in hydrocarbon production areas on the shelves of freezing seas, this proposal can be considered relevant.
