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 present invention relates to a method for preventing toxic and harmful gas from spilling from a mouth of a well during workover. The method is applied in the workover construction. In the method, an induced draft pipe is directly connected with a well mouth three-way strobe pipeline which is arranged at the position lower than a well mouth flange plane; the other end of the induced draft pipe is connected with a draft fan or a drainage box to pump out the gas in the pipeline; the draft fan or the drainage box is connected with a discharge pipeline; a low pressure area is formed in a well cylinder; when the gas overflows from the well cylinder, the gas can not spill out from the well mouth. The gas is introduced by the low pressure area to flow out from the induced draft pipe and is discharged to the place far away from the well mouth by the discharge pipeline. The method ensures that no toxic and harmful gas exists near the well mouth and does not influence the normal construction of ...
