Description
Technical field
The utility model relates to a kind of reinforcing oil well field, particularly relates to cementing head pressure testing fastening devices for a kind of well cementation.
Background technology
Past is due to cementing head use repeatly, and is not carried out in accordance with regulations the safe pressure testing before operation, causes cementing head that thorn leakage accident often occurs in cementing operation process.According to cementing head industry standard and casing and cementing technical requirements, need to carry out regular pressure testing detection to cementing head, cementing cement head pressure testing is arrived to predetermined safety value, thereby guarantee cementing cement head construction operation safety at the scene.But while carrying out pressure testing, cementing head outlet plug cannot tighten, and cannot simulate well head field working conditions, can not meet pressure testing requirement indoor.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of well cementation cementing head pressure testing fastening devices simple in structure, handled easily.
For this reason, the technical solution of the utility model is as follows:
Cementing head pressure testing fastening devices for a kind of well cementation, comprise: firm banking and at least 3 clamping leading screws, on described firm banking, be provided with the fixing hole that use is installed, and be provided with one or more concentric fixing with cannelures, the described fixing size with cannelure adapts with the size of corresponding cementing head plug, described fixing with the through hole that is formed with one or more groups along continuous straight runs on cannelure, one steady pin is installed in through hole described in every group, and described clamping leading screw is along fixing being radially arranged on firm banking with cannelure.Described every group of through hole is along the described fixing radially formation with cannelure.
Whether well cementation of the present utility model is carried out pressure testing by the installation operating mode that cementing head pressure testing fastening devices can simulation well mouth cementing head, reaches the on-the-spot tightening torque that uses, detect it and meet the demands.In addition, also can be by cementing head and other well head annex, as high pressure cock valve, the instruments such as gauge sensor, high voltage direct bend pipe combine pressure testing, detect connectedness and sealing.This apparatus structure is simple, easy to use, can improve the safety in utilization of cementing cement head by test, prevents because cementing cement head exists potential safety hazard generation personal injury accident, guarantees cementing operation job safety.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model cementing head pressure testing fastening devices;
Fig. 2 is the top view of cementing head pressure testing fastening devices in Fig. 1.
Wherein: 1, firm banking; 2, steady pin; 3, clamping leading screw; 4, fixedly use cannelure.
The specific embodiment
Below in conjunction with accompanying drawing, well cementation of the present utility model is elaborated by the structure of cementing head pressure testing fastening devices.
Referring to Fig. 1 and Fig. 2, this device comprises firm banking 1 and 3 clamping leading screws 3.On firm banking 1, be provided with the fixing hole that use is installed, also be provided with one or more concentric fixing with cannelure 4 (being provided with a plurality of in figure), each fixing size and dimension with cannelure 4 adapts with the size and dimension of corresponding cementing head plug, to meet the test request of different cementing heads.Fixing with the through hole (being formed with a group in figure) that is formed with one or more groups along continuous straight runs on cannelure 4, every group of through hole is along the fixing radially formation with cannelure 4, one steady pin 2 is installed in every group of through hole, and clamping leading screw 3 is along fixing being radially arranged on firm banking 1 with cannelure 4.
While utilizing this pressure testing fastening devices to carry out pressure testing, operation according to the following steps:
(1) select the place of fixing described device, can base be fixed on the ground by the fixing hole on base 1;
(2) take out steady pin 2;
(3) cementing head plug is put into suitable fixing using in cannelure 4;
(4) alignd with the through hole on cannelure 4 with fixing in the hole of cementing head plug horizontal direction;
(5) steady pin 2 is passed from the hole of cementing head plug and the fixing through hole with cannelure 4, and load onto nut, cementing head plug is fixed;
(6) clamping leading screw 3 is all tightened, from least three directions, cementing head plug is fixed;
(7) lay down the silk of carrying on cementing head plug, cementing head is vertically mounted on cementing head plug and is tightened, in each import of cement, load onto plug or plug valve, then connect pressure testing equipment and carry out pressure testing.
Claims (2)
