A device for profile control and water plugging of oily sludge

Abstract

The invention provides a profile control and water shutoff device for oily sludge, which belongs to the technical field of oil production related equipment and solves the problems that the profile control water shutoff agent cannot be directly produced on site, the production efficiency is low, and the movement is inconvenient. Including the transport vehicle and the complete machine base, the lower end of the transport vehicle is fixed with a waste liquid tank, the complete machine base is detachably fixed on the transport vehicle, and the upper end of the complete machine base is fixed with a material storage tank, a control cabinet, a liquid distribution tank, and several feeding boxes. , a liquid storage tank, several feeding tanks 2 and sludge raw material boxes, the liquid storage tank and several feeding tanks 2 and the liquid distribution tank and several feeding tanks 1 are connected by pipelines, and the vent holes of the liquid distribution tank and the storage tank are all fixed There is a hot steam filter, and a curved capillary is arranged inside the liquid storage tank. The lower end of the curved capillary extends out of the liquid storage tank and is connected with a back-suction fan, which is connected to the two hot-vapor filters through pipelines. The invention is easy to move, can be processed on site to prepare the profile control water blocking agent, mixes evenly, fully utilizes the heat, and speeds up the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of equipment related to oil production in oil fields, in particular to a device for profile control and water blocking of oily sludge. Background technique [0002] In the middle and late stage of oilfield development, the formation energy decreases and the recovery rate decreases. Most of the oilfields in my country begin to supplement the formation energy through water injection to improve the recovery rate. However, due to the heterogeneity and complexity of strata and oil layers, the phenomenon of water "bursting" and "channeling" in oil layers will occur. With the increase of water injection, the inhomogeneity of the water injection profile increases, resulting in a large amount of water output from the oil well. Therefore, profile control and water plugging are required. That is, when the high permeability layer is blocked from the water injection well, the water absorption profile of the water injecti...

Problems solved by technology

[0004] At present, oily sludge profile control and water plugging technology is developing in the direction of large doses of deep multi-slugs. The consumption of a single well can reach more than 10,000 m3, and the construction time can be as long as two months or even longer. Therefore, the device occupies a large area. It is inconvenient to move. In the oil production site, it cannot be moved at will. The process is cumbersome and the proportioning operation is complicated. It can make full use of heat and speed up production efficiency. Moreover, the toxic and harmful substances contained in oily sludge and the waste generated by the production of profile control and water shutoff agent are harmful to construction.
