Abstract

Abstract: Since the gas reservoir of the Dengying Formation in Gaoshi-Moxi platform margin belt was put into production, many gas wells have been blocked to varying degrees during the production process, which is manifested as a variety of complex forms of wellhead, wellbore and formation plugging, seriously restricting the normal and stable production of the gas wells. The plugging samples were analyzed by acid dissolution, infrared spectroscopy, energy dispersive electron microscopy, X-ray diffraction and chromatography-mass spectrometry, with the result that the main components of the plugs are basically the same, and there are slight differences in the components of the plugs in different gas wells and key basic data such as geological features, completion methods, and well-entry fluids were comprehensively analyzed to further determine the source and formation mechanism of blockages. On this basis, according to the different plugging degrees and types of gas wells, the pump-injecting oil-cleaning organic blockage removing agent process for the wellbore is not completely blocked, the coiled tubing flushing process for the wellbore completely blocked, and the acidizing and plugging removal process measures for the formation blockage. Twelve gas wells in the Dengying Formation gas reservoir at the edge of the Gaoshi-Moxi platform belt were de-plugged by the above technologies, and the daily recovery gas volume is 145×10⁴ m³, and the economic benefits are remarkable. A series of gas well plugging control technologies suitable for Dengying Formation gas reservoirs have been formed, which can be popularized and applied in the same type of sour gas fields.

Key words: Gaoshi-Moxi platform margin belt, plugging, organic plugging remover agent, acidizing plugging removal, coiled tubing plugging removal, chip catcher
