Abstract

The present invention relates to a water-in-oil releasing liquid and a production method thereof. The production method sequentially comprises: (1) preparing raw materials, wherein the raw materials comprise, by weight, 200 parts of water, 680 parts of diesel oil, 10-20 parts of oleic acid, 20-25 parts of slaked lime, 20-30 parts of a wetting reversion agent dodecyl trimethyl ammonium bromide, 60-70 parts of a solid emulsifier SN-1, 10-20 parts of an anti-sloughing agent FT-1, 20-30 parts of a fast penetrant T, and 20-65 parts of barium sulfate; and (2) pouring the diesel oil into a high speed stirring tank, adding the solid emulsifier SN-1 under the 20000 rpm stirring condition to stir for 15-20 min, adding the water, stirring for 20-30 min so as to make oil and water be completely emulsified, sequentially adding the oleic acid, the slaked lime, the anti-sloughing agent FT-1, the wetting reversion agent and the barium sulfate, stirring, finally adding the fast penetrant T, and stirring for 30-40 min so as to obtain the water-in-oil releasing liquid.

Description

technical field [0001] The invention relates to an oil-in-hydrolysis jam fluid, which belongs to the technical field of oil and gas drilling and is used for soaking stuck drill parts when drill stuck occurs in oil and natural gas drilling. Background technique [0002] With the deepening of oilfield exploration and development, in order to further tap the potential and increase efficiency and increase crude oil production, oil exploration is drilling towards deeper and more complex areas. In recent years, the number of some difficult horizontal wells, highly deviated and extended reach wells has been increasing year by year. In the drilling construction of these wells, pipe sticking accidents are very prone to occur due to the influence of various reasons. There are many reasons for pipe sticking, which are related to the filter cake friction coefficient, drilling fluid density, improper operation, and the contact area and contact time between the drilling tool and the well...
