The invention relates to a horizontal well leakage-proof rotational flow sand-washing device and sand-washing technology thereof. When a horizontal well is subjected to sand washing, sand-washing liquor seriously leaks in a perforation section, and is poor in washing and carrying capabilities at a horizontal section. A horizontal well rotational flow sand-washing device and a horizontal well leakage-proof double-layer oil pipe insulating circulation mechanism are communicated by a common oil pipe, and both ends of the common oil pipe are communicated with the horizontal well rotational flow sand-washing device and the horizontal well leakage-proof double-layer oil pipe insulating circulation mechanism by an oil pipe coupling. The technology is characterized in that the horizontal well rotational flow sand-washing device, the horizontal well leakage-proof double-layer oil pipe insulating circulation mechanism and the common oil pipe are connected in sequence and enter a shaft of the horizontal ...

The invention relates to a horizontal well leakage-preventing double-layer oil pipe isolating circulation mechanism. When a double-layer oil pipe is conventionally applied to perform horizontal well sand washing and well washing operation, a whole or partial double-layer oil pipe or a concentric oil pipe are adopted to perform operation, the oil pipe does not have a function of preventing or reducing stratum loss, sand washing liquid loss directly causes reduction of the working efficiency of sand washing liquid, various stratum pollutions are caused, and the oil producing capability of the stratum is reduced. The horizontal well leakage-preventing double-layer oil pipe isolating circulation mechanism comprises two identical double-layer oil pipe isolation steering connectors, namely an upper double-layer oil pipe isolation steering connector and a lower double-layer oil pipe isolation steering connector which are communicated through a double-layer oil pipe string structure. When the mechanism ...

The invention relates to a horizontal well rotational flow sand washing device. In the conventional sand washing construction of a horizontal well, sand washing liquid and stratum sand are arranged on an upper layer and a lower layer of a production casing respectively under the gravity action, the construction liquid flows from the upper layer, consequently, the stratum sand on the lower layer cannot be effectively carried to be transported together with the construction liquid, the stratum sand cannot be effectively carried to return out of a shaft, namely, the construction efficiency is low, the water consumption is too large, the sand washing effect is poor, and a construction pipe string is prone to being buried by sand. The horizontal well rotational flow sand washing device comprises a vector washing pipe and an isolation washing pipe which are connected through oil pipe couplings, wherein the isolation washing pipe comprises an oil pipe short joint and the oil pipe couplings arranged ...

The invention discloses a preparation method of a granular honey product. By taking brown sugar and white sugar superfine powder as auxiliary materials, the bonding state of honey is adjusted, and the nutritional ingredients of the honey are enhanced; by using the antibacterial effect of the honey, the addition of preservatives is avoided; brown sugar is added for color modulation and no pigment is used, so that a formula is more reasonable; and the honey is prepared into a granule form, so that the long-term transportation, storage, and post deep processing and utilization of the honey are facilitated, and losses caused by fermenting and the like are reduced. The preparation method disclosed by the invention is simple in technological process, and no heating process is performed, so that an effect of energy conservation is achieved, and the fragrance loss of the honey is small; by using normal-temperature natural drying and micronization technologies, the solubility of products is good ...

The present invention is directed to an apparatus for distributing a cable-pulling composition onto a cable as it is being pulled through a conduit. In one embodiment, the cable pulling composition is a block of an enhanced composition, e.g., consisting essentially of boron nitride that facilitates the pulling of cables through conduits. The invention further relates to a method for pulling cables through conduits by applying an effective amount of boron nitride composition onto the cable surface through the use of the cable-pulling apparatus of the invention.
