Description
Technical Field
The invention relates to the technical field of energy exploitation, in particular to a sleeve fracturing sliding sleeve.
Background
In the petroleum field, fracturing refers to a method for forming cracks in hydrocarbon reservoirs by utilizing the hydraulic action in the oil or gas extraction process, and is also called hydraulic fracturing. The fracturing is to artificially crack the stratum, improve the flowing environment of oil in the underground, increase the oil well yield, play an important role in improving the flowing condition of the bottom of the oil well, slowing down the interlayer and improving the oil layer utilization condition, and the casing cementing sliding sleeve segmented fracturing technology is a reservoir reconstruction technology newly developed in recent years. Casing gas has an effect on the density of the crude oil and the liquids in the casing, resulting in the presence of a copy of the pressure differential. The oil jacket pressure connected with the oil jacket may be unequal, for example, after the oil jacket is connected with an injection well, the oil jacket pressure is sometimes higher than the oil pressure, and the oil jacket pipe consists of a steel pipe which supports the side edge of the oil-gas well, so that the normal operation of the whole oil well during the well drilling process and after the well completion is ensured. According to the depth and geological conditions of the wells, each well uses a multi-layer sleeve, cement well cementation is adopted after the completion of the sleeve well, and the sleeve well is different from an oil pipe and a drill rod, cannot be reused and belongs to disposable material consumption. Therefore, the oil consumption of the casing accounts for more than 70% of the total consumption of the whole well pipe, the casing can be divided into a conduit casing, a ground casing, a technical casing and an oil reservoir casing, and the consumption of the pipeline is increased along with the deepening of the development of the produced energy along with the buried place.
Aiming at the problems, the invention provides a sleeve fracturing sliding sleeve layer transformation method.
However, most casing fracturing slips have the following drawbacks:
when the energy is developed, because the depth of the developed energy is different, a large number of pipelines are needed for splicing, the bottom energy is mined, the needed pipelines are spliced and mined by using a large number of pipelines along with the increase of the depth of the energy, but after the energy is mined, the mined pipelines, rotating rods and the like are always abandoned at the ground, the possibility of recycling is avoided, the pipelines with different diameters facing the pipeline types cannot be spliced and mined mutually, when the situation of misplacement occurs, the mining point from a new drilling is always needed, the fault tolerance is low, and the waste degree is large;
in the process of exploiting energy, the sleeve, the oil pipe and the drill rod cannot be reused, the sleeve, the oil pipe and the drill rod belong to disposable consumable products, meanwhile, the sizes among pipelines are different, the pipelines cannot be mutually compatible, when the pipelines are insufficient in length, a constructor is required to purchase the pipelines newly, the pipelines with different sizes cannot be used, and in the process of waiting for conveying the pipelines, the exploitation time and the exploitation cost are both one expense, so that the incompatibility of the inner diameter splicing among the pipelines is one of main reasons that the pipelines cannot be mutually spliced.
Accordingly, the present invention provides a casing fracturing sleeve to solve the above problems.
