Detailed explanation of casing head
The casing head is an important connector between casing and wellhead equipment. The casing head is an important connector between casing and wellhead equipment. Its lower end is connected with surface casing through thread, and its upper end is connected with wellhead equipment or BOP through flange or clamp. Characteristics of casing head Casing connection can be either threaded connection or slip connection. Hanging casing is fast and convenient; The casing hanger adopts a rigid and rubber composite sealing structure, and metal sealing can also be used to enhance the se
Prevention and treatment technology of casing accident
1. Ferrule 01 Handling of ferrule There are two reasons for casing seizure: One is adhesive card; The second is shaft wall collapse or sand bridge jamming. After the casing gets stuck, full pressure can be applied but no more lifting is allowed. The annular clearance between casing and well wall is small, so it is impossible to perform casing milling and backoff. 1. Sticking card When the drilling fluid can be circulated, the method of injecting the releasing fluid is the same as that of treating sticking. 2. Collapse or sand jam (
Tubing, tubing, sucker rod, drill pipe and other common oil pipe equipment are introduced
1. Casing During or after the drilling of oil and gas well, one or several steel pipes are lowered according to the design requirements to prevent the collapse of the well wall, separate the fluid of each layer, and form the oil and gas production channel. These steel pipes are called casings. Note: φ101.6mm casing is a 4 "uncoupled casing Step 2: Tubing Tubing is a special tubing for oil Wells. Tubing is divided into two ends of the thickened tubing and flat tubing according to the thickening situation. Deep well completion uses thickened tubing at both ends, whic
Coiled tubing bottom seal drag fracturing technique

Technical introduction In order to meet the requirements of fine cutting, rapid layering, full hole production after fracturing and large rate fracturing in horizontal well reservoir reconstruction, the CT bottom seal drag fracturing technology was developed. Through the optimization and improvement of core tools such as packer and sand-blasting perforator, erosion analysis and field verification, the construction performance index of full displacement of 14m3/min under quartz sand condition is broken through, and the fixed-point refined transformation of the reservoir is realized, o
1. Overview Oil well tubing is the basic material of petroleum industry, the special tubing is indispensable for petroleum exploration and development, and the bulk strategic material of petroleum industry. Its quality and performance are related to the comprehensive economic benefits and security interests of the petroleum industry. Classification of well pipe by use; Casing, tubing, drill pipe, etc.; According to the production process can be divided into seamless oil well pipe and welded oil well pipe. Casing is mainly used to support the well wall during drilling and after co
Pipe inspection standard and content
Oil pipelines are used to transport crude oil and natural gas from oil and gas reservoirs to the surface after drilling to withstand the pressure generated in the production process. The outer diameter of the pipe is generally 60.3 mm ~ 114.3 mm. End processing forms are: no thread coupling thickening, external thread coupling thickening, flat end face, no thread coupling thickening, external thread coupling thickening. Tubing inspection range Fuel oil pipe, automobile oil pipe, excavator oil pipe, oil pipe, high pressure oil pipe, hydraulic oil pipe, brake oil pipe, air compress
Tubing coupling is a kind of oil field drilling tool, mainly used for tubing connection. It mainly solves the problem of fatigue fracture caused by stress concentration of existing coupling. The structure of the tubing coupling is: the tubing end is connected with the inner wall of the coupling by means of conical thread, and the coupling body end is connected with the tubing by means of flat thread with the same pitch and thread. The utility model has the characteristics of relieving the stress concentration at the root of the external thread of the tubing with a single cone thread, an
Use and maintenance of drill pipe
Precautions before running drill pipe into the well: Before the drill pipe is used in the well, the internal thread joint shall be placed on the movable drill pipe stand 0.3m above the ground according to the specifications, and sufficient support shall be provided in the direction of the drill floor to prevent corrosion of the drill pipe caused by water, tide and soil. The drill pipe frame should be kept parallel and at the same level to prevent the drill pipe from bending and deformation; The drill pipe at both ends of the pipe frame should be clamped with plugs to prevent the drill p
1. Introduction of special buckle Special thread is a pipe thread with special structure different from API thread. Although API threaded casing has been widely used in oil well production, its disadvantages are obvious in the special environment of some oil fields. Although API round threaded string has good sealing performance, the tension of the threaded part is only 60% to 80% of the strength of the string, so it cannot be used in deep well production. Although the API eccentric trapezoidal thread string has much higher tensile performance than the API circular thread string, its se
1. Classification of pipelines Pipeline pipe is the abbreviation of the steel pipe used in the oil and gas industry to transport oil, refined oil, natural gas, water and other pipelines. Oil and gas transmission pipelines are mainly divided into three types: trunk pipeline, branch pipeline and urban pipe network pipeline. Using 406 ~ 1219 mm channel, the wall thickness is 10 ~ 25 mm, and x ~ X80 steel. Branch pipeline and urban pipe network pipeline general specification for the | 114 ~ 700 mm, thickness is 6 ~ 20 mm, the grade of steel is X42 ~ X80. Pipes Pipes include welded st
Classification and application of drill pipe
The kelly, drill pipe, weighted drill pipe and drill collar in the drill tool constitute the drill string. The drill string is the core drilling tool that drives the drill bit from the surface to the bottom of the hole, as well as the passage from the surface to the bottom of the hole. It has three main functions: (1) transfer torque, drive the bit drilling; (2) Rely on the weight of the bit to exert pressure on it to break the rock at the bottom of the well; (3) Well flushing fluid transportation, that is, drilling mud through the high pressure mud pump on the ground into the drill string hol
Classification and function of casing
Casing is the steel pipe that supports the wall of an oil and gas well. Depending on the drilling depth and geological conditions, each well with multiple casing should be used. The cement used to cement the casing after it has been run should be used. Unlike tubing and drill pipe, it cannot be reused. It's a disposable consumable. As a result, casing consumption accounts for more than 70% of all well tubing. Casing can be divided into conduit casing, surface casing, technical casing and reservoir casing according to service conditions. Guide sleeve: mainly used for Marine and desert dr
Classification and function of tubing
1. Tubing classification Tubing is divided into flat tubing (NU), thickened tubing (EU) and integral connector tubing. Flat pipe refers to the pipe end is directly threaded, and is provided with a fitting without thickening. Thickened pipe means that two pipe ends are externally thickened, then threaded, and equipped with a coupling. Integral joint tubing refers to one end through the internal thickened external thread, the other end through the external thickened internal thread, direct connection, no coupling. 2. The role of tubing ① Oil and gas extraction: after oil a

What are the classifications of tubing joints
1. Oil pipe joints are classified according to shape Tubing joints are classified into five types by shape: (a) External thickened non-thickened joint -- both ends of the same specification, one end is connected to the external thickened oil pipe, the other end is connected to the non-thickened oil pipe or special thread oil pipe (b) External thickening and reducing joints -- different specifications at both ends. One end of the tubing joint is connected to a large extra thickened tubing and the other end is connected to a small tubing (c) Outer thickening to outer
