Drilling device for oilfield exploitation

Abstract

The invention relates to the technical field of oil exploitation, and discloses a drilling device for oilfield exploration. The drilling device comprises a fixed base, wherein the two sides of the fixed base are fixedly in sleeve connection with rotary buttons; each rotary button is fixedly in sleeve connection with a connecting rod; the bottom end of each connecting rod is fixedly in sleeve connection with a supporting rod; the bottom end of each supporting rod is fixedly in sleeve connection with a moving wheel; a fastener is clamped on the top end of each connecting rod; and a sliding chuteis formed in the top end of each connecting rod. Telescopic rods are arranged at the bottom of the fixed base and are movably in sleeve connection with buffer springs; then a fixed baseplate is fixedly arranged on the bottom ends of the telescopic rods, and thus, a rotary motor is supported; a fixed drill bit is driven to rotate through the rotation of the rotary motor, and thus, fixed screws onthe side surfaces of the fixed baseplate are driven to be fixed to the ground, and thus, the fixed installation is completed; and by arranging the two fixed baseplates, the drilling device is fixed more stably, and the stability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of oil exploitation, in particular to an oilfield exploitation drilling device. Background technique [0002] An oil well is a hole drilled by drilling methods. Generally, after an oil well is drilled into the oil layer, it is lowered into the oil layer casing, and oil well cement is injected into the annular space between the casing and the well wall to maintain the well wall and seal oil, gas, and water. According to the requirements of oil field development, use perforating guns to open the oil layer to form a channel, then lower it into the oil pipe, and use a suitable induction method to raise the oil from the bottom of the oil well to the well head. Therefore, drilling engineering plays a very important role in the development of oil and gas fields.

[0002] An oil well is a hole drilled by drilling methods. Generally, after an oil well is drilled into the oil layer, it is lowered into the oil layer casing, and oil well cement is injected into the annular space between the casing and the well wall to maintain the well wall and seal oil, gas, and water. According to the requirements of oil field development, use perforating guns to open the oil layer to form a channel, then lower it into the oil pipe, and use a suitable induction method to raise the oil from the bottom of the oil well to the well head. Therefore, drilling engineering plays a very important role in the development of oil and gas fields. In the construction of an oil and gas field, drilling engineering often accounts for more than 50% of the total investment, so the quality of an oil well is directly related to the efficiency and quality of oil extraction, and oil wells need to use drilling devices for operations. Before the drilling device is used, it is necessary to manually build a fixed base and then install the drilling device on it. The efficiency is low and the installation is not firm, which is prone to safety accidents. At the same time, there is no base that can be connected to the expansion , so that once the fixed base is built and expanded, it will be very troublesome, and it may affect the work of other drilling devices, the flexibility is not high, and it is also very troublesome when the fixed base needs to be removed, and the removal Afterwards, the transportation intensity is high, which is not conducive to recovery. Therefore, a drilling device for oil field production is proposed.
