Problems solved by technology

However, this method can only balance some advantages and disadvantages of deep penetration and large-aperture perforation technology to a certain extent, and has not comprehensively achieved the ideal requirements of long penetration, large aperture, and small compaction pollution. There is still widespread controversy in the industry

Abstract

The invention discloses a granular preparation for perforation of an oil-gas well. The granular preparation comprises one or several kinds of a mixture of barium phosphate and copper oxide, a mixture of barium nitrate and chromium sesquioxide, or a mixture of potassium nitrate and ferric oxide, one or several kinds of a mixture of aluminum powder and carbon powder, a mixture of carbon powder and boron powder, or carbon powder, one or several kinds of a mixture of titanium powder and molybdenum powder, a mixture of tungsten powder and bismuth powder, and a mixture of bismuth powder and tantalum powder, one or several kinds of colloidal graphite, antimony trioxide or magnesium silicate, one or several kinds of hydroxypropyl cellulose, acetate fibers or fluoro rubber, and one or several kinds of ethyl formate, ethyl acetate or amyl acetic ester.

Description

technical field [0001] The invention belongs to the technical field of energy-concentrated after-effect perforating for oil and gas wells, and relates to a powder agent for after-effect perforating and a wet preparation method thereof. Background technique [0002] As early as the 1840s, the gunpowder propellant technology was studied as the main means of increasing the production of various oil and gas fields. By the 1970s, on the basis of a large number of experiments and theoretical Fracturing technology is becoming more and more mature and has been widely used in the former Soviet Union and the United States. The composite perforating fracturing technology is to ignite the gunpowder or rocket propellant placed in the perforating gun after the perforating bullet is detonated, make it burn, and generate a large amount of high-temperature and high-pressure gas, which passes through the gun barrel and the ring sleeve with high pressure. The rock formation is impacted in the...
