Abstract

The invention discloses a deep sea low-permeability reservoir supersonic kinetic energy fracturing ground targeting test device, relates to the technical field of oil-water well supersonic kinetic energy fracturing simulation test, and aims at improving and optimizing the design test scheme for hydraulic impact fracturing ground targeting and laying a foundation for researching a hydraulic impactfracturing fracture forming mechanism; the device specifically comprises a sleeve, the outer walls of the two ends of the sleeve are connected with an end cover and a connecting cover through fastening threads respectively, the outer wall of one side of the connecting cover is connected with an impact chamber through threads, an impact short section is arranged in the impact chamber, the outer wall of one side of the impact chamber is connected with an adapter through threads, and the outer wall of one side of the adapter is connected with a hard pipeline through threads. By arranging the sleeve, the adapter, the pump truck and other structures, the formation mechanism of the crack form generated by the cement target can be conveniently researched and analyzed, and the design test scheme of hydraulic impact fracturing ground targeting is improved and optimized, and a foundation is laid for researching the hydraulic impact fracturing fracture forming mechanism.

Description

technical field [0001] The invention relates to the technical field of supersonic kinetic energy fracturing simulation testing of oil and water wells, in particular to a ground target shooting test device for supersonic kinetic energy fracturing of deep-sea low-permeability reservoirs. Background technique [0002] Due to tight lithology, low permeability and high seepage resistance in low-permeability reservoirs, the natural productivity of oil wells is low. Among the production stimulation measures of modern oil and gas fields at home and abroad, fracturing and acidification are the main measures to improve single well production in low-permeability oil and gas fields; In terms of fracture-making mechanism, fracturing technology can be divided into hydraulic fracturing and high-energy gas explosion fracturing; hydraulic shock fracturing technology began to emerge in the former Soviet Union in the 1970s, and after field application, summary, improvement and perfection, it rea...
