Description

Workover fluid filtering device for underground workover

Technical Field

The utility model relates to a workover fluid filters technical field, concretely relates to workover fluid filter equipment for well workover in the pit.

Background

The well repair is mainly to detect and repair a series of faults such as insufficient water, water temperature drop, sand gushing, water quality deterioration and the like of tube wells such as geothermal wells, water source wells and the like, so that the fault wells or the wells which are near to be scrapped can be operated again for production. The failed geothermal wells, water wells and the like cannot normally run for production, too much electric energy is consumed under the condition of insufficient water quantity, but corresponding water quantity cannot be extracted, the basic performance of the geothermal wells cannot be exerted when the water temperature is lowered, the danger is large when the sand gushing phenomenon occurs, not only is the frequent burning of an electric pump occur, the pipeline can be blocked due to the fact that the provided water contains too much sand, but also silt can be deposited on the filter pipes at the bottoms of the well casing pipes to block the filter pipes, so that the water in the water taking layer cannot normally gush up, if the sand gushing phenomenon occurs in the geothermal wells, the silt blocks the screen pipes in the water taking section, the water in the hot reservoir layer cannot normally gush out, and the phenomenon of insufficient water quantity also occurs. If the sand gushing point is close to the stratum section of the earth surface, a large area of cavities can be formed between the strata due to the extraction of a large amount of sand, the earth surface can be settled while the strata are compact, and the buildings on the earth surface can be damaged inestimably. The workover fluid needs to be filtered in the use, but can't carry out quick abundant filtration to workover fluid solid phase at present, has not only wasted the time, has reduced filtration and staff's efficiency, and filterable not enough moreover, the use of unable fine assurance workover fluid.

Workover treatment is a maintenance measure for maintaining or improving the oil and gas productivity, workover fluid is working fluid used during workover treatment, and the performance of the workover fluid directly influences the recovery effect of the production energy after the workover treatment. The oil field generally adopts clear water, stratum water or inorganic salt solution as workover fluid, but the compatibility of the clear water and a reservoir stratum is poor, so that the hydration and expansion of clay minerals are easy to occur, the reservoir stratum is blocked, the effective permeability is reduced, and the productivity is influenced.

Based on this, the utility model designs a workover fluid filter equipment for well workover in the pit to solve above-mentioned problem.
