The present application belongs to the technical field of manifold, and particularly relates to an intelligent throttling well killing manifold, which comprises a base, a plurality of movable support assemblies are slidably connected to the base, the movable support assemblies are fixedly connected with a cross piece, the cross piece is fixedly connected with a plurality of valve body assemblies, adjacent two valve body assemblies are fixed through quick dismounting and mounting assemblies, the quick dismounting and mounting assemblies are fixed on the movable support assemblies, the cross piece and the quick dismounting and mounting assemblies are fixed on different movable support assemblies, the position of the cross piece and the plurality of valve body assemblies can be changed by changing the position of the movable support assemblies on the base, thereby the butt joint installation of the oil well pipeline at different positions can be adapted, the quick dismounting and mounting between adjacent two valve body assemblies can be realized through the quick dismounting and mounting assemblies, the quick maintenance and replacement of the valve body assemblies can be realized, the maintenance efficiency of the throttling well killing manifold is improved, the throttling well killing manifold can be quickly put into use, and thereby the downtime is reduced.

The embodiment of the invention provides a fused salt heating superheated steam generation system and a control method thereof, and belongs to the technical field of oilfield exploitation. The system comprises a water supply device, an evaporation device and a superheated steam generation device which are connected in sequence, a fused salt overflowing pipeline is arranged and used for providing a heat source for the hot steam generation device and the evaporation device; the water supply device is used for conveying the preheated low-temperature supply water to the evaporation device, so that the evaporation device converts the preheated low-temperature supply water into wet saturated steam; the superheated steam generating device is used for converting the wet saturated steam into superheated steam required by steam injection; and the control device is used for controlling the operation states of the water supply device, the evaporation device and the superheated steam generation device based on the steam injection requirement. According to the scheme, the problem that in the prior art, response to the dynamic steam injection demand is insufficient is effectively solved, the adaptability and operation efficiency of the system are remarkably improved, and the heavy oil recovery demand under the complex working condition is met.

A rodless plunger drainage gas pump. The upper end of the upper pump barrel assembly of the present invention is fixedly connected to the center tube, and the inner hole of the center tube is connected to the inner channel in the gas pump; the annulus between the gas pump body and the outer pump barrel is the outer channel; the upper pump barrel assembly and the lower fixed assembly are axially fixed; during the operation of the gas pump, by alternately pressurizing the inner channel or the outer channel, the upper plunger of the movable assembly reciprocates along the upper pump barrel of the upper pump barrel assembly, and the lower pump barrel fixedly installed at the lower end of the upper plunger reciprocates along the lower plunger of the lower fixed assembly, so that the volume of the working chamber between the upper plunger and the lower plunger of the gas pump changes to complete the suction and discharge of liquid. Its beneficial effects are that the structural design is reasonable and can meet the mining needs of wells with different inclinations; no sucker rod is used to avoid the occurrence of eccentric wear of the sucker rod, effectively reduce the number of pump inspection operations, and reduce maintenance costs; it can effectively reduce the occurrence of sand jams and corrosion in the gas pump, extend the pump inspection cycle, and improve production efficiency.
