Description

Water injection matching combined tool

Technical Field

The invention relates to the technical field of oilfield exploitation, in particular to a water injection matching combined tool.

Background

An oil field refers to the sum of oil and gas reservoirs within the same oil and gas production area under the control of a single geological structure (or stratum) factor. A field may have one or more reservoirs. The oil field is mainly the oil reservoir in the same area, and the gas field is mainly the gas reservoir. According to the geological factors in the area for controlling oil and gas production, oil and gas fields are divided into 3 types: constructing oil and gas fields. Meaning that the hydrocarbon production area is controlled by a single construction factor, such as wrinkles and faults. Secondly, the oil-bearing area of the stratum type oil and gas field is controlled by stratum factors (such as unconformity, pinch-out and lithology change of the stratum) on the background of a regional anticline or monoclinic structure. Compound oil and gas field. The oil and gas producing area is not controlled by single structure or stratum factors, but controlled by multiple geological factors. In the development process of an oil field, an oil field well and a water injection well generally exist, and in the water injection process of the water injection well, a plurality of sets of tools are often required to be matched for use so as to realize water injection operation.

Generally all can use the drill bit to carry out the preliminary treatment back to the water injection well among the prior art, and utilize the blanking plug to descend to predetermined height, and make and fix between the wall of a well of blanking plug and water injection well, and realize blockking up, do not contact between the side of the decline in-process blanking plug of blanking plug and the wall of a well of water injection well, descend to predetermined height after, just can open the blanking plug and fix between blanking plug and the wall of a well, fix with this realization, but the fixed comparatively complicated satisfying use that can not satisfy of blanking plug among the prior art.

Simultaneously, when utilizing the blanking plug to block up the wall of a well, the inside liquid height of the wall of a well this moment is confirmed promptly, can realize the water injection operation this moment through to the inside injection liquid of the wall of a well, but generally utilize many sets of instruments to realize blockking up and water injection operation among the prior art, need realize promptly that it is fixed to realize reaching the blanking plug after the predetermined height, and utilize the water injection device to carry out the water injection operation to the inside of the wall of a well, can't accomplish the combined use of water injection device and blocking device, need carry many sets of instruments, it is very inconvenient to use.

In the exploitation in-process in oil field, generally can get through the side at the oil well with the water injection well to provide pressure to the inside of oil well, nevertheless in the pressurization in-process, need guarantee that the inside of water injection well is in vertical state, and the inside of water injection well does not have the jam, generally all utilize the drill bit to take out the drill bit after clearing up water injection well inside among the prior art and reuse the blanking plug and realize blockking up, the use steps are comparatively complicated, and can't realize blockking up when unobstructed.
