Problems solved by technology

At present, with the smaller well sites such as artificial islands and mountains, if a conventional liquid storage tank group is used, it is not only limited by the well site due to the large number of liquid storage tanks, but also the traditional cuboid liquid storage tank has a tank volume. Problems such as unclean liquid drainage cannot meet the development needs of large-scale industrial fracturing of tight oil wells

Embodiment Construction

[0021] In order to have a clearer understanding of the technical solutions, objectives and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0022] Such as figure 1 and figure 2 As shown, the present invention provides a liquid storage tank group, which includes a bottom liquid storage tank 1 and at least two liquid storage tank units 2 stacked sequentially from bottom to top, and the stacking method greatly reduces the pressure of the liquid storage tank group. The footprint of the liquid storage tank group is not affected by the footprint of the well site. The bottom surface of the bottom liquid storage tank 1 is a plane and can be directly placed on the well site. The top surface is provided with a liquid inlet through hole 11, and the lower part of the side wall of the bottom liquid storage tank 1 is provided with a liquid discharge through hole 12. The liqui...

Abstract

The invention provides a liquid storage tank group. The liquid storage tank group comprises a bottom liquid storage tank and at least two liquid storage tank units sequentially overlapped from bottom to top. The bottom surface of the bottom liquid storage tank is a plane, and the bottom liquid storage tank can be directly arranged on a well site. A liquid inlet through hole is formed in the top surface of the bottom liquid storage tank, and a liquid draining through hole is formed in the lower portion of the lateral wall of the bottom liquid storage tank. The bottom surface of each liquid storage tank unit is inclined with one side higher than the other side, and the section of the bottom surface of each liquid storage tank unit in the direction perpendicular to the inclination direction is V-shaped. A liquid draining port communicated with the outside is formed in the other side of the bottom surface of each liquid storage tank unit, that is, the liquid draining port is arranged in the lowest position of the bottom surface of the corresponding liquid storage tank unit. A liquid inlet communicated with the outside is formed in the top surface of each liquid storage tank unit. The liquid inlet and the liquid draining port of each liquid storage tank unit and the liquid inlet through hole of the bottom liquid storage tank are sequentially arranged correspondingly from top to bottom. The liquid storage tank group has the advantages that the occupied space is small, liquid is not prone to being left, and the volume is easy to calculate.

Description

technical field [0001] The invention relates to the technical field of oil production engineering, in particular to a liquid storage tank group. Background technique [0002] With the large-scale development of tight oil in Liaohe Oilfield, hydraulic fracturing has become the main way to increase the production of tight oil wells, and the industrialized fracturing mode will become an important means for Liaohe tight oil development to increase revenue, reduce expenditure, reduce costs and increase efficiency. At present, with the smaller well sites such as artificial islands and mountains, if a conventional liquid storage tank group is used, it is not only limited by the well site due to the large number of liquid storage tanks, but also the traditional cuboid liquid storage tank has a tank volume. Problems such as unclean liquid drainage cannot meet the development needs of large-scale industrial fracturing of tight oil wells. Contents of the invention [0003] The objec...
