Embodiment 1

[0025] like figure 1 As shown, the embodiment of the present application provides a bidirectional hydraulic shock analysis method for improving the effect of stuck pipe treatment, wherein the method further includes:

[0026] Step S100: obtaining the first stuck position;

[0027] Specifically, during the drilling process, the phenomenon that the drilling tool is trapped in the well and cannot move freely due to various reasons is called stuck pipe. The jar is used while drilling to convert the potential energy inside the stretched drilling tool into kinetic energy. After the jarring occurs, this kinetic energy transmits a power wave to the stuck drilling tool, so that the With unlock card. Strata reasons, poor drilling fluid performance, and improper operation may all cause sticking. When a sticking accident occurs, it is necessary to analyze different situations in order to effectively relieve the stuck. The first sticking position is the specific position of the drill bi...

Embodiment 2

[0085] Based on the same inventive concept as the two-way hydraulic jarring method for improving the effect of sticking in the previous embodiment, the present invention also provides a two-way hydraulic jarring system for improving the effect of sticking, such as figure 2 As shown, the system includes:

[0086] a first obtaining unit 11, the first obtaining unit 11 is used to obtain the first stuck position;

[0087] a second obtaining unit 12, the second obtaining unit 12 is configured to obtain the first rock formation information at the first stuck pipe position;

[0088] a third obtaining unit 13, the third obtaining unit 13 is configured to perform rock formation characteristic analysis on the first rock formation information to obtain a first pore pressure;

[0089] a fourth obtaining unit 14, the fourth obtaining unit 14 is configured to obtain a first impact force threshold value from the first pore pressure, where the first impact force threshold value is a thresho...

Abstract

The invention discloses a two-way hydraulic jarring method and system for improving the drill jamming treatment effect. The method comprises the steps that a first drill jamming position is obtained; rock stratum characteristic analysis is performed on the rock stratum at the first drilling jamming position to obtain first pore pressure; a first impact force threshold value of the first hydraulic jar is obtained according to the first pore pressure; a first contact area between a first drilling tool and the first rock stratum information at the first drilling tool jamming position and a first friction resistance borne by the first drilling tool is obtained; a first jarring mode is determined according to the first contact area and the first friction resistance, the first jarring mode comprises a first jarring direction and a first impact force, and the first impact force is within the first impact force threshold value; and the first jarring mode is sent to a jarring control system. The technical problems that in the prior art, a one-way hydraulic jar is difficult to use flexibly under complex well conditions, and fish falling accidents are caused by accidental excitation easily are solved.

Description

technical field [0001] The invention relates to the field of petroleum equipment, in particular to a two-way hydraulic shock method and system for improving the treatment effect of stuck drill. Background technique [0002] During the drilling process, stuck pipe accidents will inevitably occur. Due to formation reasons, poor performance of drilling fluid, improper operation, etc., drilling sticking may be caused. Different situations must be analyzed in order to effectively release the jam, and the key to preventing the jam is to detect the abnormality in the well as early as possible and take appropriate measures. Therefore, the jar is particularly important at this time. At present, the domestic jar can only achieve one-way hydraulic jar, which is difficult to use flexibly for some complex well conditions. In addition, ordinary hydraulic jars are easy to be accidentally activated and cause fish to fall. ACCIDENT. [0003] In the process of realizing the technical solut...
