Корреляция параметров и показателей гипсовой залежи Кругловского месторождения (Пермский край)

Корреляция параметров и показателей гипсовой залежи Кругловского месторождения (Пермский край)

Abstract

Kruglovskiy field is a quite simple geological structure of small thickness of productive layers, and includes a small amount of karstic and off-grade rocks. We analyzed the spatial distribution of the following parameters and indicators of deposit: thickness of gypsum strata, the average content of gypsum in the well, thickness of overburden, the thickness of karst intervals, thickness of the substandard grade rock, elevation of surface relief, and elevation of the top of gypsum and the top of anhydrite layers. There was observed close and very close correlation between the pairs of indicators. Positive correlation was established between the elevations of relief and top of gypsum layer, elevation of the top of gypsum and the top of anhydrite, and elevation of relief and the top of anhydrite layer. Negative correlation was revealed between overburden thickness and elevation of the top of gypsum layer, overburden thickness and elevation of the top of anhydrite layer, and between overburden thickness and thickness of gypsum stratum. The correlation results indicated that gypsum deposit has, in general, sheet-like shape, a groundwater table elevation changed in the process of hydration of anhydrite relative to the earth's surface, the big thickness of overburden brought a negative effect on the formation of deposit, and its total thickness of gypsum strata was relatively small.

Кругловское месторождение характеризуется довольно простым геологическим строением, небольшой мощностью полезной толщи, включает незначительное количество карстовых и некондиционных пород. Проанализированы пространственные соотношения следующих параметров и показателей залежи: мощностей гипсовой толщи, средних содержаний гипса по скважине, мощностей вскрыши, карстовых интервалов и некондиционных пород, отметок рельефа земной поверхности, кровли гипса и кровли ангидрита. Установлены тесные и весьма тесные корреляционные связи между парами показателей: 1) положительные между отметками земного рельефа и отметками кровли гипса, отметками кровли гипса и отметками кровли ангидрита, отметками земного рельефа и отметками кровли ангидрита; 2) отрицательные между мощностями вскрыши и отметками кровли гипса, мощностями вскрыши и отметками кровли ангидрита, между мощностями вскрыши и мощностями гипсовой толщи. Результаты корреляции свидетельствуют о следующем: гипсовая залежь в целом имеет пластообразную форму; зеркало подземных вод в процессе гидратации ангидрита изменялось согласно с земной поверхностью; большая мощность перекрывающих гипсовую толщу отложений явилась отрицательным фактором при формировании залежи: ее общая мощность оказалась сравнительно небольшой.
