Embodiment 1

[0020] Such as figure 1 As shown, the petroleum-based oil well cement mixing system of the present invention includes a stirring cup 1 and a horizontal placing plate 2 for fixing the stirring cup 1. The placing plate 2 is provided with a first groove 3 that runs through the upper and lower ends of the placing plate 2 , the inner wall of the first groove 3 is provided with threads, the lower end of the stirring cup 1 has the same shape as the first groove 3, and the lower end of the stirring cup 1 is connected with the first groove 3 by threads; the placing plate 2 is provided with Through the first circular groove 7 on the left and right sides, the placing plate 2 is placed in the moving plate 4, the upper end of the moving plate 4 is open, and the first groove 3 in the moving plate 4 is provided with a second groove 5, and the moving plate The side of 4 is provided with the second circular through groove 6 corresponding to the first circular through groove 7, and the first te...

Embodiment 2

[0024] Petroleum-based oil well cement mixing system, on the basis of Example 1, when the first circular channel 7 corresponds to the second circular channel 6, the distance between the first groove 3 and the second groove 5 It is 5cm. Between the bottom surface of the placing board 2 and the inner bottom of the moving board 4, a number of spring rods that can expand and contract in the vertical direction are arranged.

Abstract

The invention discloses a petroleum-based oil well cement stirring system. A placing plate moves up and down in a moving plate. When the placing plate moves to a lower end, a first groove makes contact with the inner bottom of a second groove; and when the placing plate moves to an upper end, a first circular through groove and a second circular through groove correspond to each other. During stirring, the first groove is located above the second groove, and the first circular through groove and the second circular through groove are correspondingly and fixedly connected with each other through a first telescopic rod. During separation, the placing plate moves downwards in the moving plate, and the first groove makes contact with the inner bottom of the second groove. The petroleum-based oil well cement stirring system is simple in structure and convenient to operate and use.

Description

technical field [0001] The invention relates to the petroleum field, in particular to a petroleum-based oil well cement mixing system. Background technique [0002] Oil well cement is specially used in the cementing engineering of oil well and gas well, also known as plugging cement. Its main function is to cement and seal the casing and the surrounding rock formations, to isolate the oil, gas and water layers in the formation, and to prevent crosstalk, so as to form a well-isolated oil flow channel from the oil layer to the ground in the well. The basic requirements of oil well cement are: the cement slurry should have a certain fluidity and suitable density during the well injection process; after the cement slurry is injected into the well, it should set quickly and reach a considerable strength in a short period of time; the hardened cement slurry should It should have good stability, impermeability and corrosion resistance. [0003] In the petroleum field, oil well ce...
