Description

Skid-mounted device for gel plugging

Technical Field

The utility model belongs to the technical field of the gel plugging device, concretely relates to sled dress device is used in gel leaking stoppage convenient to clearance.

Background

The leakage is the most common problem in the drilling process, the leakage degree of the leakage depends on the difference value between the pressure of a liquid column in a well and the pressure of formation pores, the development degree and the communication condition of a crack, the width and the length of the crack, the rheological property of fluid in a leakage passage and the like, and the leakage not only affects the normal drilling operation, but also affects the quality and the safety of the next well cementation. The conventional plugging modes can be divided into two types, one type is temporary plugging, materials such as following plugging, re-plugging and direct use of 3H and the like are added into slurry or the slurry for plugging, but the obtained plugging effect is temporary, and the well leakage is easily generated again due to the pressure fluctuation of a liquid column in a well or the scraping effect of a downhole tool on the wall of the open hole section. The other type is permanent plugging and cement injection plugging, wherein the permanent plugging effect is achieved by forming firm cement stones in a leakage passage by using cement slurry.

A gel is a solid, jelly-like material that is a special dispersion that is not flowable and often contains a large amount of liquid inside. The application of the gel in plugging is that the gel enters the leakage passage under the action of pressure difference and stops pumping when the pumping is stopped due to the higher viscosity, so that the gel is retained in the leakage passage and is quickly cured to plug the leakage passage.

At present, when plugging is carried out through gel, the gel is mostly stored and stirred through a skid-mounted device. The skid-mounted device is a form of integrally combining an equipment frame and equipment, means that a group of equipment is fixed on a chassis, can be used by being directly connected with a pipeline, and can be directly moved to any use place without installing a valve, an instrument and the like in the middle, and for example, the skid-mounted device for repairing and killing a well plugging agent for a gas well is disclosed in Chinese patent application with application publication numbers of CN110394111A and 2019.11.01. Current sled dress device for gel includes the base usually, installs the staving on the base, and the staving has feed inlet and discharge gate, is equipped with stirring structure in the staving, and stirring structure includes the pivot and sets up at the epaxial stirring vane of commentaries on classics, is equipped with on the staving to link to each other with the rotatory drive structure of drive pivot with the pivot transmission.

Among the prior art, in order to prevent remaining gel solidification on the stirring vane, used up sled device at every turn after, all need clear up remaining gel, but because stirring vane is located the staving of sled device inside to because the pivot among the prior art links to each other with drive structure is fixed usually, make stirring vane follow staving in the dismouting come out comparatively trouble like this, and then also make the user be not convenient for clear up remaining gel on the stirring vane.
