Slip loading capacity testing device and method

Abstract

The invention relates to the technical field of oil and gas field development, in particular to a slip pressure bearing capacity testing device and method. The slip pressure bearing capacity testing device comprises a pressure testing machine, a cone tool, a sleeve and a cushion block, the pressure testing machine is provided with a first pressure plate, a second pressure plate and a pressurizing component, the sleeve is arranged between the first pressure plate and the second pressure plate, the cone tool is arranged in the sleeve, the cone tool comprises a first tool part and a second tool part, the second tool part is provided with a conical surface, and the cushion block is arranged in the sleeve and matched with the sleeve; according to the slip pressure bearing capacity testing method, the slip pressure bearing capacity testing device is adopted to test the pressure bearing capacity of a slip; according to the slip pressure bearing capacity testing device, whether the pressure bearing capacity of the slip can meet the design requirement or not is tested by simulating the anchoring state of the slip in an underground casing pipe, it can be guaranteed that a bridge plug is stably anchored to the designated position by adopting the slip with the pressure bearing capacity meeting the design requirement, and fracturing construction safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of oil and gas field development, in particular to a slip pressure-bearing capacity testing device and testing method. Background technique [0002] In oil and gas exploration and development, bridge plugs, as a downhole plugging tool, are widely used to block the lower well section during layered fracturing of oil and gas wells. Slips are used as the anchoring parts of bridge plugs. The bridge plug bears pressure to realize bridge plug setting and anchoring during hydraulic fracturing construction. Therefore, the pressure bearing capacity of the slips will directly affect the setting effect and pressure bearing capacity of the bridge plug, and will also affect the hydraulic fracturing reconstruction reservoir. layer effect. Such as figure 1 As shown, the existing slips include several slips 41 and hoops 42, the slips 41 are surrounded by the hoops 42 into a cylindrical shape, and the slips 41 are provided...

AI Technical Summary

Problems solved by technology

[0003] Therefore, before the bridge plug is put into use, it is very necessary to test the pressure-bearing capacity of the slips. If the slips whose pressure-bearing capacity does not meet the design requirements are used during fracturing construction, the bridge plug cannot be stably anchored at the designated position, thus Cannot achieve the effect of effectively stimulating the specified reservoir, affecting the production of oil and gas wells
