The invention provides an experimental method for researching the fracture reorientation in the oriented perforating and fracturing process. The experimental method comprises the following steps of: A, making a test piece by a core exposure cube of which the side edge is greater than or equal to 1m; B, then arranging the test piece in a three-axis stress loading device and sequentially carrying out oriented perforating and fracturing on the test piece under the three-axis stress loading condition; and C, after carrying out fracturing, analyzing the test piece. The experimental method provided by the invention has a more reliable test result and is convenient to observe a fracture extension rule.

The invention relates to an acidic surfactant fracture liquid system. The system comprises 2.0-5.0wt% of cetyltrimethylammonium bromide, 0.5-2.5wt% of potassium biphthalate, 10-20wt% of hydrochloric acid, 0.1-1.5wt% of hydrofluoric acid, and the balance water. The fracture liquid system is suitable for 40-60DEG C reservoir stratums, can be used for acidifying unblocking and sand addition fracturing, and is diluted and broken by stratum water or an organic fluid after the fracturing construction.

The invention relates to the technical field of calcium carbide production, particularly relates to a technology for recycling screen underflow, and particularly discloses a lime briquetting production line. The lime briquetting production line comprises a ball press, a ball discharge belt conveyor, a large-inclination angle belt conveyer, a first vibrating screen and a product storage bin, wherein the ball press is used for pressing and molding a lime ball; the molded lime ball achieves the first vibrating screen via the ball discharge belt conveyor and the large-inclination angle belt conveyer; and the first vibrating screen conveys the molded lime ball to a calcium carbide furnace via the product storage bin. The quantity demand of calcium carbide smelting on the lime material is ensured while unit cost of calcium carbide is reduced; the lime underflow ball is recycled; the benefit of the lime powder is maximized; and meanwhile, the pollution to the environment caused by transportation ...
