Problems solved by technology

[0003] However, there are many problems in the use of oil and casing. For example, since Changqing Petroleum Exploration Bureau discovered casing damage in July 1973 in Ridge 5 of Maling Oilfield in Longdong area, as of 1993, there have been a total of casing failures in the entire oilfield. 433 wells with pipe damage

Embodiment 1

[0035] like figure 1 , 2 , 3, this embodiment provides a corrosion-resistant oil casing, including a casing body and a current sensor; the above-mentioned casing body sequentially includes an insulating protective layer 5, an anode sacrificial layer 2, a core support layer 1, The connection layer 3; the anode sacrificial layer 2, the core support layer 1 and the current sensor are electrically connected in sequence.

[0036] In this embodiment, it includes a casing body and a current sensor, wherein the current sensor can be a common commercially available component, which is easy to purchase and replace. The current sensor includes an ammeter, and the ammeter is connected to the control terminal, so that the user can know the resistance Whether there is current generated in the corrosion-resistant oil casing to detect the working state of the corrosion-resistant oil casing.

[0037] The above-mentioned casing body sequentially includes an insulating protective layer 5, an a...

Embodiment 2

[0056] This embodiment provides a method for preparing a corrosion-resistant oil casing, which includes the following steps: after heating and expanding the anode sacrificial layer 2, it is sleeved on the outer peripheral side of the core support layer 1; after the anode sacrificial layer 2 is cooled and shrinked, An insulating protective layer 5 is sheathed on the outer peripheral side of the sacrificial layer 2; a connecting layer 3 is sheathed on the inner peripheral side of the core support layer 1; a flexible buffer layer 6 is filled between the core supporting layer 1 and the connecting layer 3; the inner peripheral side of the connecting layer 3 The inner protective layer 4 is applied.

[0057] In this embodiment, the following steps are included: the anode sacrificial layer 2 is sheathed on the outer peripheral side of the core support layer 1 after being heated and expanded; after the anode sacrificial layer 2 is cooled and shrunk, an insulation protection is sheathed ...

Abstract

The invention provides a corrosion-resistant oil casing and a preparation method thereof, and relates to the technical field of corrosion-resistant oil casings. The corrosion-resistant oil casing comprises a casing body and a current sensor, the casing body sequentially comprises an insulating protection layer, an anode sacrificial layer, a core supporting layer and a connecting layer from outside to inside, and the anode sacrificial layer, the core supporting layer and the current sensor are electrically connected in sequence. According to the corrosion-resistant oil casing, the corrosion resistance of the oil casing is improved, and the reliability and safety of long-term working of the oil casing are guaranteed. The invention further comprises a preparation method of the corrosion-resistant oil casing pipe, the beneficial effects are achieved, meanwhile, the working condition of the corrosion-resistant oil casing pipe can be detected in real time through the preparation method of the corrosion-resistant oil casing pipe, and the reliability and safety of long-term working of the oil casing pipe are guaranteed.

Description

technical field [0001] The invention relates to the technical field of corrosion-resistant oil casing, in particular to a corrosion-resistant oil casing and a preparation method thereof. Background technique [0002] The special oil pipe (oil casing) is mainly used for the drilling of oil and gas wells and the transportation of oil and gas. It includes oil drilling pipes, oil casings, and oil sucking pipes. Oil drill pipes are mainly used to connect drill collars and drill bits and transmit drilling power. The oil casing is mainly used to support the well wall during the drilling process and after the well completion, so as to ensure the drilling process and the normal operation of the entire oil well after the well completion. The oil pipe mainly transports the oil and gas at the bottom of the oil well to the surface. [0003] However, there are many problems in the use of tubing and casing. For example, since the Changqing Petroleum Exploration Bureau discovered casing ...
