Reducing pile for jacket and jacket leveling method
The invention relates to a variable-diameter pile for a jacket and a jacket leveling method, the variable-diameter pile for the jacket comprises an upper pile section, a variable-diameter pile section and a lower pile section, and the upper pile section is columnar; the lower pile section is columnar, and the size of the cross section of the lower pile section is larger than that of the cross section of the upper pile section; the variable-diameter pile section is arranged between the upper pile section and the lower pile section; wherein the upper pile section, the lower pile section and the reducing pile section are an integrated pile, and the interior of the reducing pile is hollow; when the variable-diameter pile is installed, a small-pile-diameter pile hoisting device and a small-pile-diameter leveling device can be applied, hoisting of the variable-diameter pile and leveling of a jacket are achieved, the purchase cost of the pile hoisting device and the leveling device is reduced, and the development cost of an oil and gas field with the water depth range of 300-400 m is reduced.
本发明涉及一种导管架用变径桩及导管架调平方法，导管架用变径桩包括上桩段、变径桩段、和下桩段，上桩段为柱状；下桩段为柱状，下桩段的横截面尺寸大于上桩段的横截面尺寸；变径桩段设置在上桩段和下桩段之间；其中，上桩段、下桩段和变径桩段为一体桩，变径桩内部中空；变径桩在安装时能够应用小桩径吊桩器和小桩径调平器，实现变径桩的吊装和导管架的调平，降低了吊桩器和调平器的购置费用，降低了水深范围为300m‑400m的油气田的开发成本。
